| 2|2|2002-09-16 12:24:21|s56al|I wonder...|
I wonder what is the purpose of this transceiver? ICOM throw the
VHF/UHF and 100W HF/6m PA capabilities out of the IC-706 to gain the
space for antena tuner? Hopefully is the RX current consumption
lower as that of IC-706 if the '703 wants to be "portable" with it's
10W PA.
Has anybody already seen this transceiver offered by any supplier or
knows the estimated price?

Best regards,
Aleks, S56AL

Hi!

Good question Alex. I guess ICOM decided relise this
radio on the market, because pressure of the YAESU become
a principal. Concernig price, no idea.

Hi there

Seen any info ( test ) from FCC on the IC-703 ??

/ Tilman SM0JZT
| 6|2|2002-09-24 07:35:28|tthulesius|Re: I wonder...|
I think that ICOM wants to provide the features that are missing
with the FT-817. Like Speechprocessor, Autotuner and DSP.
Also FT-817 is waisting spece for a useless batterycompartment
where the IC-703 uses the space for someyhing usefull.
I would have liked if the rig would have been smaller
but on the other hand it is good that the 706-option
can be used also for the 703.

According to spec the rig will draw 250 mA. Not bad att all
compared with FT-817 and others. So this is a truly
portable rigg -( remember it includes a Autotuner ).

B.t.w
The tuner needs a balun if you have a high-Z antenna
like a longwire.

--- In IC703@y..., "tthulesius" case (easily modified for safe NiMh use) has gold plated contacts
(for whatever thats worth) and seems well constructed. A set of
cheap 1900mah Gold Peak AA NiMh batteries will provide for about one
hour of SSB QSO on maximum power output. Carry two sets and you have
plenty of operating time if you really need it, AA cells are very
light.
Also battery technology is continually advancing, sanyo just came out
with 2000mah AA NiMh batteries for example (even these are going
cheaply, www.batteriesamerica.com was selling them for US $3.50 at
last check, making a 2000mah 9.6v set [the battery compartment takes
8AA cells] less than US$ 29). I would not be surprised to discover
that soon even larger capacity AA cells will come to market. Just
about 1 year ago 1600mah cells were considered high capacity.

I love the battery compartment because: AA cells are much cheaper
than amateur battery packs (allowing the user to purchase new cells
as technology improves at a low price), AA cells will never be
discontinued (unlike a proprietary battery pack), AA dry cells are
avaliable in almost every area of the world (great in an emergency or
for a special need if your NiMh run out unexpectedly) and NiMh aa
cells are widely avaliable in the developed world--this is great for
tourists who find their batteries drained while at a location they
will not visit again...just buy some aa drycells and make that once
in a lifetime qso before getting back on the bus/in the car, the AA
cells I carry for my 817 can be used to power any other devices I may
be carrying (although its not good to unbalance the cells) such as my
GPS or ham ht (ft-530 or vx-5r) or handheld scanner or camera or mini
mag lite in a pinch- THEY ALL HAVE BATTERY COMPARTMENTS (sometimes
optional) FOR AA CELLS.

Personally I find that I use the 817 as a carry along rig and rarely
find myself walking for more than one hour. If I am going to be out
operating for much longer, I might as well treck along my 706mkiig
and a big SLA battery.

I would have loved to see a battery compartment for standard cells on
the 703. That way I could have saved money and would not be forced
to purchase any proprietary packs from Icom that were not compatable
with my other rigs. Also I would be able to purchase standard
replacement cells when traveling abroad, even if my charger/power
supply failed or was incompatable with the local power grid (if the
grid is running).

Sorry to be so long winded, but I think standard cells have many
advantages that hams who have not used them may be unaware of.

I prefer to have a good tuner built into a portable rig over skinny battery
capacity.

You do nto have to use ICOM-packs connected to the rig when external.
There are hundreds of 9V6 and 12V-packs out there that can be used.

I hav converted the battery-compartment in my beloved FT-817 including a
switched voltage-control så that I can run my FT-817 on a cool and
healthy 10 volts although running from 12- 13V8.

Have a look on my homepage for FT-817-bits.

Thats true, however then you need power connectors for each piece of
equipment. My yaesu equipment (817, ft530 and vx5r) all uses the
same external power connector, however my ht scanner and my radio
shack ht have different ones, my gps has no external power connector
and neither does my mag lite. Also it seems like all of the HTs out
there now have AA holder cases, while they all have different power
connectors making the AA cells a universal power supply.

It just occured to me that it might be very limiting to power the 703
from standard NiMh AA cells because I dont think they can deliver
much more than 2 amps draw. NiCd may provide more amperage......

Also thanks for the webpage. I have read about power dissapiation
and voltage on the 817 and would like to see the what you have done.

Hi there

Nothing wrong with a FT-817. I have one and I'm perfectly happy with it.

To honest, the only reason to buy a 703 should be.

1. It has a built in tuner (Lineflattener) - I use resonant antennas
......
2. You can remove the operating head - But the FT-817 is so small so you
do not need stow it away.
3. ICOM might have better after market support in your area.

I will have a firts look and try with the 703 this weekend. Look forward
to it.

Hello anxious Icom 703 Future users.

My reply from Icom USA was that they hope for release to the US
market at the end of March 2003, pending FCC approval. This means 6
1/2 weeks to Dayton Hamvention.
Of course, you have to remember that a bird in the hand beats 2 in
the bush......we'll all believe it when we see the 703 in the USA at
our favorite dealers. Universal Radio has it listed as a "future" HF
radio for sale on their website.

Hi Charlie,

ICOM brought 12 of them to the Baltimore Hamfest yesterday and gave 4
each to the radio dealers that were there. I have one of them on my
desk now and am playing with it. Looks nice. The tuner matched my
R8 over the full 40 meters which my FT-897 tuner certainly would not
do, nor will my FT-1000MP MK V tuner. The DSP noise reduction seem
to work very nicely also.

ICOM said in 2-3 months they would likely have the HF and 6 meter
version approved for sale if I wanted to wait. (Not likely.)

| 35|35|2003-04-03 21:08:55|chris6955|been playing with the IC703|
This week I have had an IC-703 on loan from Icom UK!
The UK version comes with DSP and 50mHz as standard.
The radio really needs the 455khz filter and as there is only an
option for 1 so you will have to choose between cw or ssb.
When running from 13.8 volts the radio gives 10 watts and the ATU
seems to cope with an SWR of less than 4.5 to 1 on most bands.
The external battery only gives 5 watts so a gel pack will be a
better solution.
All in all it is an OK radio and 10 watts is useable. The radio will
I am sure appeal to the UK foundation license holders but for me I
think I will stick with the FT-817 for portable operation. If I can
not make it on 5 watts then I probably wont make it on 10 watts either
They are expected in the UK in about 4-6 weeks and price will be
about £600.00

Thanks Paulo,

I found an IC-703 at the Link you gave me and it is on its way!

Looking forward to many QRP hours. I have used several IC-706 rigs
ant this one is very similar except no heat, no noisy fan but better
receive and newer features.

I'll keep you posted.

Rick <| 37|36|2003-04-06 03:07:29|Roy Crosier|Re: I found an IC-703!|
Today I attended a hamfest and saw 10 brand new
703 radios. They have the tuner and 6 meters
built in. They were being sold by the Associated
Radio Communications store of Overland Park,
Kansas. The normal price is $669, although some
hamfests have the Icom coupons for $40 off.
Associated's phone is 800-497-1457.

I asked if I could look at a manual and they let
me. It says the radio will work down to 9 volts
in the field, and the receive-only draw is 300 mA
when squelched.

Anyway, it looks like a great radio, but the
downside is that the 706 is being discounted to
$729 at some hamfests, so one does wonder if
not getting the 144 and 440 bands is worth
a hundred dollars. I know that a purist QRP
operator won't want the 706, so no flames please.

The manual also said that the 703 is menu selectable
down to one half watt output, much like the FT817
menu.

first models avaliable here will only support HF. The HF/50Mhz model
will be available later this summer. Correct me if I'm wrong.

| 39|36|2003-04-06 17:21:51|Roy Crosier|Re: I found an IC-703!|
Rick & the group:

YES!! I didn't believe it either since I had been
reading this listing the past few months. I checked
both the box and the manual and they both said
"HF + 6" The down side is that there is only one
antenna connection for both, unlike many radios
that provide a separate antenna for the bands above
HF.

Hi All,

Does anyone know if these early models will be upgradeable to 50Mhz
when the new batch comes out later this summer. I feel a little
queasy having a radio that says HF/50Mhz on the front panel but
doesn't work on 50Mhz. Might not be too good for resale value.

Cheers,

I too saw the 6 meter version at a Michigan hamfest this past
weekend. A Michigan ham dealer known as ComDac had 2 of them. I only
wish I had the money to buy one. Oh well, it willo have to wait.
I was suprised to see them there because I also heard the 6 meter
version was not out yet but I saw one.

Hi Chuck,

Did you actually turn the radio on and tune up to 6 meters? The ICOM guy
said none were being released in the USA until later this Summer. The face
plates and boxes do say HF/50MHz but the band is disabled on the one I
purchased.

Tom N4ZPT



| 45|42|2003-04-08 01:59:29|Tom Azlin, n4zpt|Re: Can they be upgraded?|
Hi Rick,

That is the question!! I opened up mine to see what was there. It looked
like the tuner had several "missing" coils and relays. I am hoping there
will be an upgrade "kit." Even without the kit is looks like a nice
alternative to building a K2.

Regards, Tom N4ZPT
| 46|42|2003-04-08 02:30:00|Rick Riverman|Re: Can they be upgraded?|
Those are my exact sentiments also. I came soooo close to buying a
K2 because I thought these 703 rigs were never going to become
available. Then I saw a posting on the hfpack group last week about
the availability on the east coast and so I ordered one. Should be
here Thursday. Yes, I too hope there will be an opportunity to
upgrade for a reasonbable fee. But you are right, it specs out to be
a considerably better rig than the K2. We'll see...

Cheers,
Rick <



| 47|36|2003-04-08 03:04:29|cleskie|Re: I found an IC-703!|
No I did not actually turn it on but the plates/ boxes were labeld
HF/50mhz.
If it did not actually have 6 meters in it, it's good I didn't buy
it. Because I would have felt mislead.

I agree Chuck. The dealers at the Baltimore Hamfest were careful to tell us
that these radios and boxes (and manuals by the way) were miss-labeled.
Sounds like to me that the radios were software programmed at the last
minute to remove 6 meters given they had not yet passed the FCC tests but
wanted to get the radios on the market.

Hello all,

I am a JUNKIE when it comes to QRP gear, having dropped bucks on about
all of 'em at one time or another. When I compare this rig to the 706,
I just don't see the value. It has a built in tuner which is nice and
has low draw on receive. Now, it still needs an external battery, so
why not go for a 706 at about the same price and get the other bands.
It'll still turn down to about 3 watts, but that old 100 watts is
there if you need it. Just don't see the value of the 703 at the
curtrent price. I'm betting that if you want one and are willing to
wait a little, you'll get a better price later as they gather
dust...........

Bill in Az. de N3KHI
| 50|49|2003-04-09 16:12:11|Rick Riverman|Re: I don't know....|
The problem with using the 706 for QRP is that it draws almost 2 amps
continuously in receive mode. It generates so much heat internally
during receive that the fan cycles on every five to ten minutes,
causing it to draw even more current. The 703, on the other hand,
has no fan and only draws about 250 ma during receive, about 1/8 that
of the 706. That is a HUGE difference in battery consumption rate,
which is what QRP is all about.

Also, because it doesn't need all the heat sinking cast aluminum
frame, the 703 has room to incorporate a built in antenna tuner--
something that is usually needed for QRP portability, but not always
needed for mobile or fixed station operation.

So basically, you get the best of both worlds with the 703: energy
saving low power consumption with antenna tunning needed for QRP
operation, and the fancy features found on the heat generating, power
hungry 706.

I think that if ICOM can get past their initial release confusion
with two models with the same markings, they will have a real winner
here.

Cheers,
Rick < W7RBR

I agree with what you say Rick. Even so I plan to hold off a while
before I buy a 703 for 3 reasons.

1. One I think the price will come down to be more even with the
FT-817.

2. I also want to wait and make sure all the bugs are worked out of
the rig, although I don't really expect to see to many flaws show up.

3. I would like the 6 meter version.

In the mean time I will be monitoring the good and bad points of this
rig and if all goes well, I might be selling my FT-817.

heretic to the cause. That is why I originally
stated that the 706 at a hundred dollars more
gave you more for your dollar than the 703.
I became disabled three years ago so I no longer
consider walking up hills and carrying gear and
batteries. My QRP now is all done from home using
a Yaesu FT-920 turned down to the lowest setting.
I still own several QRP single band units and I
am constructing a transmitting attenuator to
hopefully play with milliwatting or even micro-
watting. Anyway, I said all that to say this:
I think the 703 would be a great bargin at say
$400 or so. I also think they will come down
in price because many non-hikers will take the
706 instead. That will mean that Icom will
sell the 703s out and quit making them. Then
there will be a black hole in the market until
somebody else picks up QRP again in a few years.
Look at the same thing that happened the last
solar cycle--Kenwood brought out things like the
660 and 670, not enough people bought them, they
added 100 watts (680, 690) and dropped the QRP
line, in the USA at least.

Having played with the 703 and the FT857 side by side I think Icom
are going to struggle with this one.
When using batteries the FT857 will run up to 20 watts the icom is
only 5 on batteries!
The internal ATU is at best a swr flattener so no good for random
wires. It is big and looks old fashioned.
I just can not understand why Icom left off VHF and UHF
I use an 817 for portable and a 706 for mobile and can see no merit
in a 703.
Also the filter really is a must on the 703 it aint cheap and it only
takes one. Another ommision that seems pointless!

The 857 don't have a battery compartment. You might be refering to
the 897. That rig runs close to a thousand dollars.
The 703 is closer in price to the 817.

Yaesu has some nice rigs in the 857, 897, and 817. I own the 817 and
have seen the other two. I guess it's all personal preference, but I
am not real fond of the tiny display used by all three of the Yaesu
rigs and at least on my 817, the buttons are so small, It's hard to
push one button without hitting the one next to it, or in the case of
the function button, I keep bumping the VFO.

As far as the 703 only taking one filter, the FT-817 only takes one
filter as well, and I paid 159 dollars for it. Hardly cheap.

The tuner might not work on all antennas, but it should work fine
with homebrew diploes or vertical antennas and to me is a trade off
for the lack of VHF/UHF. Besides, I have an HT or the 817 for that.

There is one advantage to the Icom. At least in my opinion. I have
owned several Icom HF rigs as well as Kenwood and Yaesu. The thing
that would sway me to the Icom is the track record I have had with my
other Icoms. No Icom HF rig I have owned has ever went down on me
yet!! I can't honestly say the same thing about my Yaesu or Kenwood
rigs I have owned. I know this is a personal observation and others
may have different experiences, but I have been very lucky with Icoms.

Actually though, I might eventually get the 703 and possibly keep my
817 as well. Then I'll have twice the fun hi hi. Both rig have their
good and bad points.

--- In IC703@yahoogroups.com, "cleskie"
When run on external batteries the 703 is 5 watts and the FT857 is 20
watts !!!!!!!! I do not think people realise that the 703 does not
take internal batteries!!!Also a lot of people do not realise the
FT857 can run off 9.6 volt batteries.

Filters for the 703 list at 50% more than the yaesu and the 857 takes
2 filters.

For portable the 817 is what I use. If I used a rucksack then the 703
would not be my choice.
When hill walking VHF/UHF is very useful for emergency comms so I
feel it is a serious ommision.

I do not want to get into a yaesu is better than icom war but Icom
have seemed to miss a lot of useful bits off the 703 and when I put
one on a 40m dipole at night it leapt about like a cat on a hot tin
roof while the 817 and 857 did not. I can only speak as I find and
assuming the 703 Icom loaned me is not a pre production sample I have
to say it does not come up to my expectations.

Prices and six meters

I noticed today that HRO's online catalog
lists both the HF only model and the HF+6,
but also states that the HF+6 is not in stock.
I know they often give better prices than they
list in their publications and I would certainly
hope this is the case with the 703. They have
it priced quite high, much more than Associated
Radio. I don't see it listed yet on the AES
web site.

The idea of a HF QRP rig with simplified design is great. The K2 is
out of the question since anything assembled is usually of
questionable quality and limited resale value. The current Yaesu
rigs are over-designed, user unfriendly, and gaudy looking. The
Argonaut V is nice but I can't get used to the idea of paying $800
for a rig with a fluorescent display. I never work VHF/UHF and only
use 20 meters, 30, and 15 - mostly digital and a little CW. Throw in
the 703's built in tuner (much more useful than all the bands I never
use), and the built in DSP (no need to play the UT106 waiting game)
and this rig is very attractive. If the early reviews are good and
the rig sounds good on SWL (my 2nd pastime) I'll buy one. Ken
| 61|61|2003-04-17 05:02:05|ws4v|New ad in QST |
Saw the new IC 703 in the recent QST ad. Looks nice. It doesn't say
anything about the front panel being removable like the 706. However
it wouldn't be necessary since most wouldn't be running the radio
mobile where the front panel would be a help.
Wonder how this will fare against the 817...
| 62|62|2003-04-17 07:04:20|Tilman D. Thulesius|IC-703 vs FT-817|
Hi there

I would say that the IC-703 has most of the stuff the FT-817 does miss.
Some bits that I have found:

AF-speechprocessor
Only HF (+6M) = less compromises
Autotuner - Great to be able to finetune them antennas used in the field

Full QSK - For the CW friends
Low RX current drawn (300mA) - not bad for a featurerich TRX
Detachable front panel - Great for outdoor use. Only take out the
frontpanel
of the rucksack and off you go.
A great display. The small size of the FT-817 is a pain even hen you
have a good eyesight.
The front panel of the FT-817 is very small and distruptet by the silly
BNC-connector
for a VHF/UHF antenna.
It has a buit in TCXO , where you have to pay extra with the FT-817
It has a DSP as option. In some markets it comes as standard.


Only drawback visavi FT-817 might be that it is a bigger unit....

So the IC-703 is for sure a rig to consider over the FT-817

That silly BNC conector allows me to connect HF ariels when the FT817
is over my shoulder. The VHF and UHF are great when out hill climbing
to a DX spot.
I went out this afternoon HF was dead except 40m (Stood no chance
with 5 watts) and I worked a lot of stations on 144mhz ssb
I know there will be those who like the Icom but don't try and
compare the IC703 with the 817 !
There is no other radio like the 817 and I think Icom would be brave
to try and copy it. The 703 will find its place in the market but it
will not nick sales from the 817. It might nick a few from the 897
tho. I still think the major let down on the IC703 is no internal
batteries

Chris:

I agree that the BNC connector is handy, and so
is having internal batteries to a point. I sold
my 817 because I grew tired of the menus, small
display and small buttons. I intend to buy a
703. There is not much 2 meter SSB in the US,
much to my dismay. Probably has to do with
the lack of population density here, but I think
we fail to use a very interesting mode and band.
I have stopped hitting my head against a brick wall
after trying for years to generate more interest
in 144 SSB/CW.

Since this is not a busy reflector and we have
several English friends, please allow me to
share another type of story. (It is not entirely
off topic because one of the Englishmen in this
story does not speak because he is using his
new '703.)

An American was in Europe and got on a crowded
train car. The American saw that a French woman
was sitting next to a window and her dog was
sitting in the seat next to her. The American
asked if he could please have he seat but the
lady refused, saying several things about the
arrogance of Americans, their wanton warlike
nature, their uncalled-for boycott of French
goods, and so forth.

The American walked on through the train, but
after going into several cars and not finding
a seat, he returned to the French woman. He
again asked her to move her dog and she began
cursing him, his heritage and questioning the
number of his legitimate parents. With that
the American became angry, grabbed the dog,
threw it out the window, then sat down.
The woman was in great anger and she looked
to the English men around her and said that
they should do something about this barbaric
American in their midst.

The American looked at one of the English men
and asked what he should have done. The English
man looked back and said:

"You Americans always make the wrong decisions.
First, you drive on the wrong side of the street.
You take your coffee on the run instead of making
time for tea, and you think that a bonnet is
something that goes on a woman's head. And now you
have gone and thrown the wrong bitch off the train!"

Hi,

I'm strongly thinking about the 703 to compliment my FT-817 and also as the
basis for CAT software for the 703/706 (see my website for my free FT-817
offering). I would use it from my car up in the Swiss alps, mainly for
PSK31.

Has anyone compared the SW rx performance with the FT-817? Does anyone had
the CAT codes for either the 703 or 706 in a format they could mail me or
point me at?

External batteries don't worry me at all as I take a rucksack no matter
what.

I'm hopping (for the sake of your development) that they have just
added commands(maybe for the 703?) I can only assume that there
maybe some "NEW" commands like ATU On/Off etc.., maybe not?

I think with the number of 706's around,
if you do develop a Commander "70X" (706/703)
you will have an instant winner.

Hi,

Let's see, but I have pretty well decided to buy a 703, it's ideal for what
I want when driving up to a mountain pass in the car. I live at 1,050m (see
my website) and it's nice to be able to go somewhere where there is no
background noise, play PSK31 for a few hours, then come home. I'm not really
interested in 2m / 70cm, and have the FT-817 anyway.

I have pretty well all the bits I need in my FT-817 software, so making 703
software would not be at all difficult. What I like about ICOM's approach is
common commands across the range of radios, whereas Yaesu is a bit of a
dog's dinner.

My current schedule of work would allow me to start on 703 / 706 / 7xx
software in July, and as I can rob code from my FT-817 software I guess it
would have something working that is similar to the FT-817 software by the
end of July / mid-August time.

All

I have here a 703.

The spec in Sweden includes a DSP and 50MHz.

The DSP is doing a wounderful job also when doing digital modes.
I have a optional CW-filter in (FL-52A, 500Hz) that is very pleasant
to listen to. Somewhat pricey but really worth it.

The CI-V-interface I have made myself using a MAX-232. Schematics
are on the net.

I was looking at the ICOM America download area and saw the IC 706 user
guide but the CAT codes were either missing or I was too thick to see them,
anyway there would be a good chance that they are similar if not a superset
of the 703 commands.

Maybe I should look for a sponsor for this project :-)

Because I've already written a very feature-rich program for the FT-817 I
can steal lots of code, so a project like this should only take 4 weeks to
get something that can be demonstrated.

--- In IC703@yahoogroups.com, "Simon Brown" Hi Simon,

I would assume the 703 would just have maybe some additional
codes for some of the features not present in the 706?
ATU, Power Levels, etc. I would think something built around your
817 Commander to support the 703/706 would be very well received.
Would you do the integration to your PSK Deluxe?

I'm away from home 5 days a week.. Unfortunately my employer
blocks access to Newsgroups/Egroups so I may not be the right
person to do the sponsorship/promoting etc.. Although I could do
testing at weekends?

Hi,

Yes , of course I would integrate PSK31 Deluxe. Looking at the CAT commands
I think I may be able to support sliding the filter over the waterfall as
(and I hope I'm right here) I think the IF shift can be set via CAT as well
as read.

So just imaging this - slide the filter around via the PSK31 Deluxe
interface! I would love to do this with the FT-817 but sadly...

I was only joking about sponsoring the project :-)

Hi all,

After helping Simon with testing the FT-817 Commander and PSK31
Deluxe I have decided to climb on the bandwagon and get myself a '703
too.

One concrete question: does anybody have experience using the 500Hz
CW filter for data modes? Is it set up as standard to have its
passband centred around 1500Hz if used for data modes (just like the
FT-817) ?

| 101|73|2003-04-27 19:14:53|Roy Crosier|my little disappointment|
I have been studying the online manual for the
'703 lately and I think I have an unanswered
expectation.

I owned and sold my FT-817 because of all the
tiny menus and small buttons it took to navigate
them. I also had to always have the book or a
cheat sheet with me to remember how to switch
things. That is OK for the at-home rig, but not
for going mobile/portable/man-pack, whatever.

I think what I want is something with the
specifications, size and coverage of the '703,
but not the "features." I would like to see
a radio that provided CW, SSB and maybe AM/FM
on 10 and 6 or higher, and would sell for maybe
$350 to 400. I don't need the digital modes and
all the other bells and whistles, except for a
few memory channels. I probably don't even
need memories since most of my hamming is done
on FISTS, county hunter or 29.6 channels anyway.

I just fear getting out in the bush and getting
something accidently changed and then not being
able to reset it because I forgot the menu. I
know it would be different if I did PSK or RTTY
on the move, but I don't. I'm not entirely a
Luddite as I do own a computer, but I still like
some things simple.

How far off base am I? Flames are OK because
my skin is made of out-lawed asbestos.

Sounds like a Patcomm PC-500 might fit the bill for you. For $395 you
get a 0-15 Watt rig with CW & SSB (and digital modes) on two bands of
your choice; extra band plug-in modules are available at $35 each. It
comes with an adjustable SCAF bandwidth filter (with no AGC pumping
reputedly) and is well-rated by those who've entered reviews on
eHam.net. Very simple user interface with *no* menus.

| 105|105|2003-04-28 03:22:45|mrcoffee_12001200|My Icom 703|
Purchased yesterday, been on for over 24 hours. My thoughts. The
little radio is somewhat susceptable to rf keying the rig in cw mode.
After attaching a ground wire and cleaning the rats next away from
radio, it's much better.

Radio puts out 12 watts on all bands with 13.8 volts. Nice.

Tuner copes with quite a wide range of mismatches. Every now and
then, it won't tune, but will select a previous setting for the band
I'm using. A problem when I change antennas. The reset function
does not seem to help this. Oddly enough, this problem seems to be
going away as I use the rig.

The DSP works well. I have an IC-718 with 706dsp module installed.
I find the 703 dsp works approximately as well. Really quite nice.

I have read that the ssb receive audio is muddy. This is true. I
have an IC-706 and it's much better. Using an external speaker to
fire the audio at operator really cleans up the problem nicely.

The rig has a feature which allows you to get a graphic display of
SWR over huge area of the band you're on. This is super nice,
effective, and well done. Again, I like the tuner, it works better
than expected and I have an email to Icom to find a resolution to my
sometime problem of tuner defaulting to previous setting. Likely
user error, but won't know until i get my reply.

Transmit audio reports using stock mike and compression are very good.

Receiver is excellent. I don't live in a "ham rich" area, so i can't
say how well the unit will work with lots of strong signals nearby.
But even without a narrow filter, the cw contest last night was
wonderful on this little rig.

Overall, I really like the radio. The tuner WILL tune a non 50 ohm
load (unbalanced load to be precise). I have used 3 different
antennas, a mobile whip with wire counterpoise cut for no particular
band, an mfj multi-band vertical with the counterpoise removed
(again, unbalanced - got feedline radiation but that's expected), and
an indoor window sill mount coil tapped whip with an unknown length
counterpoise. All work and have made contacts thru all 3.

The size of the radio is really no larger than my ft-817 with LDG-z11
tuner. thinking of it this way, it's pretty nice. Light as well.

I like it and will keep it warts and all. If Icom has fixes for any
problems that may come up, i'll probably send it in for a warranty
upgrade.

The menu features are pretty much exactly like those of the 706, with
a few added niceties. very easy to use, a joy to operate.

Just set the max out to 5 watts and you have 5 watts. The 703 switches to
5 watts max when the supply voltage is less than 11 volts and switches back
(if you have it set) to 10 watts when the voltage goes above 11.4 volts.

I have a known good (great) antenna....88' dipole fed (up 30 feet)
with 450 Ohm ladder line connected to a manual tuner. I've worked
the world with this antenna on one watt and less (CW and PSK31). In
fact, I worked Alaska and Washington using this antenna on 1 watt
last evening at 0200 UTC using the '703 on 40 meters.

I have built a Buddipole for 20 and 17, a 44' vertical dipole fed
with 300 ohm twin lead into an external tuner, a wire vertical cut
for 40 meters and a 40 meter Hamstick mounted on a chainlink fence
with a counterpoise.

| 134|133|2003-05-10 19:28:33|Peter Halpin|Re: First impressions?|
Hi all,

Roger asked:

I have had mine for six days now. I have been able to compare it to my K2
and FT-817, and the first impressions are reasonably favourable. I only
bought this so that I can help Simon HB9DRV develop Ham Radio Deluxe...

Plusses:

Easy to use with stubby fingers....that's important to me.
Receiver is quite lively, and I think it compares quite ( a lot) favourably
with the '817. It's not in the same class as a K2, but then again - what is?
DSP works as well as my outboard W9GR DSP III in autonotch and noise modes:
that says enough.
I used to have a plain vanilla '706 years ago, so I found operating this
thing easy out of the box, even with the added functions.
TX audio is said to be very reasonable using default settings.
Setting it up for digital modes is dead easy: but WHY have Icom decided that
LSB should be the default mode? RTTY fixation?
The rear DATA connector is FT-817 compatible and works a treat (but see
Quirks later)
The autotuner seems to have a much wider range than Icom specify. I haven't
tried random wires yet, but a variation on the W3EDP loaded up OK.
Basic selectivity is better than an FT-817 with stock filters. The 500Hz CW
filter is STEEP, but now I wish I'd bought a 250Hz filter instead: much more
handy with PSK31 (and what is planned with Ham Radio Deluxe).
Build quality seems OK too.

QUIRKS:

Why Icom say that the rig is suitable for 9k6 packet is beyond me: haven't
they heard that we should be using NARROW FM on 6m? That's a waste of a
connection on the DATA socket :-)
The power supply cable is a little odd - and that's me being very
diplomatic. And of course it uses a non-standard plug/socket assembly.
It wouldn't have cost more to make the autotuner a true wide-range job (but
then sales of extras would drop)
No mobile mounting bracket supplied as standard.


Does it replace an FT-817? I don't think so: it is more that it complements
the '817. You can't stick a 703 in your anorak pocket and nip out to the
park with the dog. I reckon Icom are aiming this more at people who go to a
fixed spot for a while and want something easy to operate. I think that it
could be called an IDEAL holiday rig.

By the time Simon HB9DRV gets through with it this should be a very useful
rig indeed.

Conclusion: I like it. I could get to love it, but given a choice my K2
stays and the rest go...

the the difference is.

73, Peter
| 137|133|2003-05-11 22:17:22|Peter Halpin|Re: First impressions?|
Hi Peter and others,

Oh dear! I will not be popular with the Icom fans for this, but there is no
real comparison. The K2's RX is MUCH better. The rig's noise floor is so low
that it seems as if there is silence between signals - with the '703 there
is always some noise around. The K2 has no problems on 40m in the evening
with a full-size NVIS dipole - with the '703 you have to use the attenuator
and play with the RF gain. I haven't been able to make proper measurements
(yet!) but subjectively the '703 is not in the same class...not by a LONG
way. It's probably about average. But we shouldn't compare apples and pears
here: for what it is, the '703 is a NICE rig. I can see it becoming my
digital modes rig full-time, leaving my K2 for other things. I am privileged
to have both, but if I had to dispose of one then I am afraid the '703 would
go. I don't need many of the (nice) features it has, but I can understand
how my K2 works, and I can repair it myself if anything ever happens to it -
that's not possible with a '703.

I like my '703, but I LOVE my K2 - it's as easy as that.

Hi!

HRO doesn't have the Plus (HF/6m) version yet, and the guys
at the Phoenix HRO store don't have an ETA for it yet. Don't
know about the other stores mentioned above, but rather than
waiting a while for the HF/6m version to show up - and since
I don't normally operate on 6m, despite having that band on
my FT-817 and IC-756Pro2 I already own - I went for the HF-only
version last week.

Why is the HF-only version available now and not the HF/6m
version? One possibility... if you have the HF-only (#18)
version, it does not come with an FCC ID number or the CE
seal (for Europe) on it. Icom could get that into stores in
many places as is, without 6m, before making the HF/6m versions
plus the other versions that have to clear the FCC or CE
certification processes (and/or meet any other country-specific
regulations). Not unusual for some Icom gear - their IC-R3
receiver was available in Canada for many months before a
version with an FCC ID (and the big reception gap at 815-902
MHz) appeared in the USA.

Unlike the 756Pro2 I have at home, which only transmits in
the ham bands, the 703 will transmit outside the ham bands a
little bit - like the 706Mk2 and 707 I used to have. It's a
neat radio, but I need more time (and better HF propagation)
to really put it through its paces before deciding on whether
to use it (at 5W) or my FT-817 for Field Day next month. It
played nicely yesterday at home, hooked up to my verticals,
while running off a 12V 7Ah gel-cell battery. Chances are I
will take both of those radios, but look to run the 703 as
my Field Day radio in another 1B/1-op/QRP/battery effort from
somewhere in northern Arizona instead of my trusty FT-817.
Or, I could find a friend and go with a 2B/2-op/QRP/battery
effort using both radios. Hmmm....

Hi!

Just saw this on the ARRL web site:

http://www.arrl.org/news/stories/2003/05/14/100/?nc=1

Not a "band", but 5 channels (5332, 5348, 5368, 5373, and 5405 kHz),
USB (2.8kHz bandwidth), with a 50W ERP limitation relative to a 0db
antenna for each channel. Count 30 days from when this Report &
Order appears in the Federal Register before it becomes official
for US hams to use these frequencies (not there yet, according to
the ARRL web-site article). And get the 60m mods ready...

The text of the Report & Order is available from FCC at:

http://www.fcc.gov/Daily_Releases/Daily_Business/2003/db0514/FCC-03-105A1.doc

or

http://hraunfoss.fcc.gov/edocs_public/attachmatch/FCC-03-105A1.doc

as a Microsoft Word document. I could not locate it as a text

Well,

I got my rig last week (big thanks to Chris Taylor at Martin Lynch UK). My
initial reaction is very positive, I like it a lot. I am looking forward to
starting the software development by the end of next week.

By comparison with the FT-817 I would say it is better thought out,
especially the menu system. I found I can do everything without reading the
fine manual. Other things like the flip-down stand give it an edge, but of
course you can't go portable with internal batteries, but who goes portable
with just the rig? You also need antenna, 6-pack, sandwiches, etc. so an
extra battery is no big deal. It's also a bit heavier, but we're all young
fit athletic types?

Peter Halpin showed me a PSK31 waterfall with the CW filter switched in -
it's quite a bit sharper than the FT-817 with the 500Hz filter. If you're
just going to sit in the shack then I would say it's better, but I haven't
really used it much yet. Got to sort out the pigsty here first :-)

Hi!

reading the

If you've used a 706 (any version) previously, this radio is
pretty easy to figure out. I had to read the manual to see
details of the SSB-D mode (select RTTY, then hold the mode
button until this change appears on the display - not too hard),
and some other things not in common with the 706s. In general,
with a straight key or mic I was able to get on the air quickly,
and spend the quality time reading the manual later.

Just a 6-pack? ;-)

I have the 500Hz filter as well, but haven't installed it yet.
Since these filters require soldering, I wanted to give the
radio a workout before I make that commitment. Any problems,
and I would have been back at the store getting another one.
The filter will probably go in my 703 this weekend, barring any
unforeseen problems.

For SSB, the stock filter IMO does a better job than what you
get standard with the FT-817. This opinion could change next
month, as I'm tuning through the SSB portions of the bands for
ARRL Field Day, but I'm not as concerned with a single filter
socket in the 703 as I was/am with the FT-817. Two filter
sockets would have been better, but I like what I've seen and
heard so far. Having the TCXO in there (bought one for my 817)
and the DSP module (not available from Yaesu for the 817) are
good things, along with the built-in tuner and additional output
power. As Simon mentioned, for me extra batteries would go
along even with the 817 and its internal pack, so this is no
issue with my 703.

If these two radios were available 2+ years ago, when I bought
my 817, I probably would have gone straight to the 703. Along
with what I like in the 703, I'm normally partial to Icom
gear. The FT-817 has been a fun little radio, used from many
locations in W/VE/XE, haven't had the problems that some mention
on the 817-specific lists (failure of the PA sections, for
example), and I'm hoping to have at least the same fun with the
703.

Too bad I didn't just break down and get my 703 *before* my
recent trip to Mexico 2 weeks ago. I had enough with me
down there, and didn't want to tempt the 2 Mexican Customs
checkpoints with yet another transceiver in my car (I had an
IC-W32A, FT-817, IC-706Mk2, RadioShack 10m radio, GPS, cell
phone, and radio accesories) - even if it was out of its original
packaging, packed with my other stuff, so I could avoid an
involuntary contribution to the local economy. Oh well.....
there's time to get it on the air before Field Day, and on other
trips, in the next few months.

Have a great weekend, and 73!

Hi,

Does the rig have reverse polarity protection? I've just wired up a PSU to
my new rig and will be starting software development next week.

Having this and the FT-817 side-by-side I must say the 703 is much easier to
use by a long way!

The manual describes the optional filter installation with the filter
soldered in. Is it really necessary to solder it in if the IC-703 is
not going to be used as a backpack rig. I ordered a 500HZ filter but
may want to switch it to a 250HZ, or a 400HZ from Inrad or even a SSB
filter. I have learned from experience that un-soldering is much more
problematic than soldering.

Hi Dave,

I just wired up the rig for PSK31 (big thanks to Martin Lynch again) and can
tell you the 500Hz filter is very sharp - knocks the socks off the FT-817 in
this respect. Chris Taylor shipped me the rig with the filter already
installed.

Dear all

I am very disappointed, that the DSP does not have an audio bandpass filter
for CW.
Bandpass with DSP is sooo easy, much easier than noise reduction and
automatic notch.
It's absolutely ridiculous. A few lines of software. There is no technical
reason not to implement it.
It is like a pocket calculator that has a square root function but doesn't
multiply.

What I believe: They did it on purpose - to protect the selling of IF
filters.
Shame on ICOM!

I agree the 500 X-talfilter in the IC-703 is superior to listen to.

Great that ICOM did do something more then just doing a QRP aout of the

Bit of a shame though that the built in AT only covers SWR 1:3.

| 159|159|2003-05-22 20:16:27|Eric Sluder|Just Joined The List After Getting A 703+ At Dayton|
Thought I would join you all in the discussion. I picked up a 703+ at AES In Dayton
for around (I think) $649 plus lots of Ohio tax. They're shipping me the CW filter and
carrying handle this week - man the filter is EXPENSIVE!

So far, I can't complain about the radio. Being a 706MKIIG owner, I hooked it up and
began using it right away. Ironically 6 mtrs was experiencing a band opening and I heard
stations from all over the SW USA booming into Indianapolis, IN with just a 4' whip hooked
up so I could begin listening to it - what a riot!

I bought the radio to use on overnight stays in hotels while in NW Indiana on business.
I also purchased a new manual tune screwdrive antenna on a tripod w/4 and 10 foot whips
by MFJ. They don't even have a product number for it yet. After having a lot of discussion
with the Engineer who designed it, I just had to have it because it seems like it will work
well for my applications including FD. I can use the 4' whip with the coil and tripod mount
in the hotel room on 20 mtr - 2 mtr. So 20 mtr CW here I come....

The only disappointment so far is, when using 6 FM through a repeater they didnt' include
a 'dup' feature in software. You have to use both VFO's to use a repeater - a pain in my
opinion. Of course this isn't the primary purpose for the radio, but considering it's software
driven through menus it should have been left in when they used portions of the code from
the 706 series (and yes they did, I asked the ICOM rep and he told me so... cut's down
cost when developing the radio along with using the shell of the 706 series...).

If anyone knows of a softpack for it (besides the ICOM Backpack), please let me know. I'd
like to be able to protect it for travel.

Eric W5WLW/9

Hello to all,

My name is Chris Thomson and I must confess that I have been lurking for some time, on this, and associated groups. I am trying to make up my mind as to which rig to purchase. The Icom Press Release compared their radio to Rig X (FT-817) and came up favourably. Unfortunately I learnt today that their RRP is $2154.00 AUS.

This is almost double the price of a FT-817.

Is it twice as good ?

The Japanese Press Release said that ICOM would price the 703 under 100,000 Yen. If I do the maths that makes it around $1200.00 AUS not $2154.00 AUS.

I will ring Icom Australia and ask some questions.

Thank you Simon and Peter for a great job with FT-817 Commander and charging for your time at AR rates. Hi Hi.

Even though I don't own a QRP rig yet, I could access the FT-817 Commander program using an Icom RS232 cloning cable plugged in. This picked up enough RF hash from my QTH to think a FT-817 was connected.

Regards,

Chris VK6TNC

It's actually a little bit longer (depth) than the MKIIG. From the front
of the face plate to the extreme back on the 703 (the four corner
protrusions) is very slightly longer than the MKIIG from the front of the
face place to the extreme back on the heat sync. The specs I read on most
of the retailers websites are way off in depth.

"""""" Conditions were not too good today. I was out /PM from 1625Z
to 1810Z.

Initially I could only hear three to four stations, all European, on
the band.

Just after 1700Z I began to hear people on 18157.5 just at the noise
level. I heard Bob, AA2VK on Long Island saying he was going to
change to his 2020, but could not work him. Also heard AG4XH. Iput
out some calls and wwas answered by Jim, VA3MN. I think Jim must be
a regular listener on 18157.5; this is the third time i have worked
him as a /PM.

I then actually worked Marty, AG4XH in Florida - thanks for staying
with me Marty.

I then heard Gerry, W2GLA working KP2(?)GLZ/PM. I gave Gerry a call
and he ebded up working two pedestrian mobile stations at the same
time. Unfortunately the other /PM station could not hear me and i
could just hear him at the noise level - not well enough for a QSO.

Glenn, VE9GM then gave me a call after which KB8??? called me.
Unfortunately I could not get his suffix despite mny requests for him
to repeat it, and th "KB8" coming through loud amd clear. This was
at 1805Z. After this conditions seemed to deteriorate so decided to
call it a day and returned home to my Sunday supper.

This morning I visited the "open day" of my local ham radio emporium.

Some great bargains (for the UK) were to be had. For eaxample the
following rigs, new, boxed and complete with DSP units where
applicable were available, The price includes 17,5% Value Added Tax.

FT 817 £489
FT 857 £720
FT 897 £899
and
IC 703+ £515

I was sorely tempted but my XYL had sewn up my wallet pocket before I
left home.

The Icom stand had a 703 up and working in its LC156 backpack. On
first acquaintance a relly sweet combo. The first time I have seen a
major manufacturer catering for the HFPack type of person. A really
inspired touch was the "703" mobile log book held in the interior
mesh pocket of the LC156. The special thing about this was the 703
crib sheet/cut down operating manual printed in the first few pages
of the log book.

It seems to me that Icom are really going after the HFpack market.

If the rig had 20+ watts I would have unpicked the sewing on my
wallet pocket and to H*** with the consequences:-)

Hi all,

Randall asked:


Well, the stock SSB filter, of course!

The rest are options: and you can only fit the one. This has to be soldered
in too - I MUCH prefer that, but it does mean that swapping filters is not a
task to be taken lightly. The rig has to be dismantled to do it...

| 186|186|2003-05-27 20:42:39|Eric Sluder|703+ Update (Hamvention minus 9 days)|
Made a couple of 10 watt SSB contacts over the weekend (still waiting on my CW filter).
Got great audio reports, and the rig worked just fine. I'm discovering more features each
time I use it. I've already used it on 6 FM and received good audio reports through a local
repeater there as well. Still need to try it out on CW and PSK31.

I haven't enjoyed a new radio like this in a long time. I think Icom put a lot of thought into
this radio. Too bad it looks so much like the 706 series, I'm sure some folks are going to
think it's just a 706 with different finals - wrong! I will say, getting use to the latching relays
in the tuner is a real hoot! It sounds like you're tearing up the radio when you manually tune
the radio. My wife and kids thought I had done somthing terribly wrong to the radio while we
were on the back porch yesterday afternoon enjoying a cool Memorial day cook-out and Dad was
working HF!

Hi Chris,

I have echolink on the computer, but I hardly ever get the chance to use it.

I do have MSN Messenger, but that's really meant for communication with
Simon :-)

To keep this on topic: Simon and I have been brainstorming with Skip Teller
and great strides are being made with PSK31 Deluxe. PSK63 support has been
added (not PSK63F, I must say) and various improvements have been made.
Testing is still going on, but Simon hopes to have something ready by the
weekend. He'd better do, 'cos I am taking my '703 top Scotland for a while:
watch out for MM3ECN/P during the middle part of June.

Anyway: check either/or www.hb9drv.ch and www.halpin.tomaatnet.nl on

Just got my 703 and was trying out keyboard CW using the CWTYPE
program. setting was paddle off and full break in or semi-breakin.
Ran into problems on the higher power settings. type any letter and
get a "continuous" cw transmission. Would have to shut down 703 to
get it to stop. Problem exists on all the amateur frequencies.

At the lower power settings[1-7], the keyboard cw worked normally. I
use an optoisolator circuit between the computer and the rig. Iambic
keyer and straight key work fine.

I use the program and the circuit on my 706 at full power and have no
problems. any suggestions? Thanks.

I can't help you there. Where has the group gone? Perhaps all the
703's are in for repairs. After 3 days the tuner doesn t tune and
there is no power output on transmit.

That 66 foot dipole for 40 meters must have been too much for the
tuner and the finals to handle.

Never again will I buy a new model.

Hi ho Hi ho it's to the shop we go.
| 196|194|2003-06-01 00:26:17|n1ix@att.net|Re: PLEASE READ if you have used 703 on CW|
The IC703 works well in QSK mode but it is not a TenTec.
You can hear another station between dits but you can also hear the relay.
The relay is not a distraction if you are using phones. My usual CW speed is 28
wpm but I have used it at 30+.
I have had the FT-817 and various TenTec gear including the Argonaut 5.
Each of the radios has its strong points.
The Argo 5 with its smooth QSK and DSP bandpass filters. The FT-817 has VHF and
UHF capabilites. The IC703 with its exceptional receiver, DSP noise reduction,
and antenna tuner. The DSP really works well to eliminate noise.

--- In IC703@yahoogroups.com, "hamjerr" my 703 has been AT the Icom repair facility since May 12. I called
this past wednesday, and they have not touched it. The gentleman I
spoke with said "oh - it's a new radio, i'll see if I can bump it up
in line for you...".


Anyway, The finals are blown for no reason, the rig keys itself in CW
mode making it almost impossible to use in that mode unless I cut the
power way down.

On the positive side, I really liked the radio and the swr and band
use graphs. Very functional. I found the audio "muddy", some do ,
some don't, but mine is definitely muddy. I have an ft-817 and ic-
706 and ic-718 among other rigs to compare with. The 703's audio is
muddy.

I found the memory keyer nice, easy to use. The tuner worked much
better than advertised, and the DSP is very nice. Hopefully Icom
will fix these problems for me.

On a similar note, I had to send my 817 into yaesu for repair.
Similar problem. I had the radio back in hand in less than 3 weeks,
and that includes at least 6 days of UPS/Postal service transport
time.

I think that the radio is functionally excellent, well designed.
After I get it back, I'll use it until fall, and if it's still
unbroken at that point, I'll buy the cw filter.

Interesting review, I am a bit disappointed for failure to
mention of the different IF filtering and any affects that
may have on the radio verses the 706, and how well the filtering
works. UPS messed up my order with AES and my filter went
to my old QTH instead of my new one, so I'm still out my CW filter.

Also, very little was mentioned on the software changes and how
it accomodates the CW QRP'er. I own both radios, and assess
a marked difference in the two radios software features.

and
reassembly :^) It's been on receive for over 100 hours, and I've made
numerous contacts at the 5 & 10 watt level. The tuner still tunes...

There will always be a bad unit make it past testing in a manufacturing
facility. I've been in the technology business way to long to not see at
least one bad unit occasionally. I think this reflector would be humming
if there was an upward trend towards failed radios. I think it's quiet

I called Icom today and they put a brand new rig in the mail to me.
They said my unit had an odd phase-lock loop problem and rather than
make me wait until they found the problem, they would rather just
send a new unit. I find that acceptable. They admit that they are
training on the 703 and prefer not to train on customer's rigs.

Group,

Picked up the 703 at Dayton. Really like it and have received great
signal reports. I have an intermittent problem with the internal
keyer if I do not have the rig grounded.

Question, how do most of you handle a ground (if at all) when using
the rig as a portable unit. I have not had a chance to play with a
random wire laying on the ground from the rig's ground lug, etc. I
would like to use it as pedestrian mobile.

As I said, with a proper ground it works great.

Any suggestions?

Hi all,

Brought a brand new IC703 home from the Atlanta hamfest Saturday and
2nd QSO with 9 watts into a 20m hamstick dipole at 10 feet was with a
fellow psk31 enthusiast in Spain! This is a new world for a fellow
whose rig up to this point has been a 1970's vintage Kenwood TS-820.

Regarding transmitter drive level.... I've got the 703 mic gain right
at a mid-scale reading of 5. Then I adjusted the sound card output
upward while watching the LCD bargraph power output indication on the
703 until it just lit the last segment over the indication for 10
watts. The sound card adjustment ended up being pretty close to mid
scale. I checked and no ALC action was evident but on-the-air tests
reported IMD readings in the -18db range.

Subsequently, I decreased the drive so that ALL BUT THE LAST segment
over the 10-watt indication was lit, and then on-the-air reports were
a more satisfying -25db.

Is this a reasonable approach? It didn't seem like simply making
sure that there was no ALC action was sufficient. How have you all
been setting your drive level?

Man, that 703 is a hoot!

Ken
| 213|212|2003-06-09 16:21:24|Simon Brown|Re: IC-703 PSK31 drive level|
Hi,

How the IMD is measured really depends on the other station's software. It
is only possible to measure IMD while you are Txing but not sending out
characters - i.e. it's on Tx and you are having a beer. It also depends on
the background noise as well (the IMD, not the need for the beer).

So just make sure there is never ALC, myself I do that and also don't drive
more 5W out.

I'm using mine for CW contacts on the back porch right now. The ground
setup is nothing more than
a 10 guage wire clamped on a 2 ft rod in the ground. The antenna is either
a manual screwdriver
on a tripod with two 33' ground radials, or a 33' vertical wire, with a 33'
counterpoise w/ the
groud mentioned above. The keyer works fine.

I have ordered a Ten Tec artifical ground kit for use in hotels with a
counter poise. It will be
interesting to see if the keyer still works okay. I would recommend using a
tuned counterpoise
to the band you are operating on, or the artificle ground unit like the Ten
Tec, or MFJ if you
can't effectivity keep RF out of the radio.

Normally I would assume it's just bad luck, but this is the second
radio that I have ordered from Gigaparts and they listed it as in
stock. Then they say they are out when I call to ask how long it is
back ordered. Then I get a date about a week from whenever I call
that they will be "expecting a shipment of them in." Well, today when
I call again, they claim not only to have never had the 703+ in stock
at all, but they say it will be late July before they could fill my
order, at the earliest. I cancelled my order. I guess I'll have to
go elsewhere and pay a bit more for it. It's ironic that just about
every other dealer online lists the radio as in stock. I know that
they are available, due to the owner's reviews/comments off the list.
Just figured I would see if anyone else on here has had the same
troubles out of Gigaparts, with the 703 or other radios for that
matter. 73's

No experience with them, but I bought my 703+ from AES
at Hamvention. I placed a separate order for the CW filter
and carry handle while there and they were to ship it to me
after the show. I indicated that I'm in the process of a job
transfer and need it shipped to my temp address in Indianapolis.

I called about 10 days later and asked where my filter and handle
were. Bud who is the manager of the OH store said it shipped
two days after Hamvention. UPS got the address wrong in
Indy and rerouted it to my TX address (somehow) which
stumped both Bud and myself.

Long story short, he put a tracer on it at UPS and they admitted
fault. In the meantime I got another filter and handle three
days later from OH and Bud took care of the lost shipment
with UPS. That's customer service, so I'd recommend looking
into AES for your radio. By all rights, he could've made me
wait until the package in TX got back up this way!

--- In IC703@yahoogroups.com, "tcnic52" yes, i picked up one of the first serial numbers of the plain 703,
and it would key itself in cw mode on 40, 30, 20, and 17 if running 5 watts. Icom said to ground the rig shortest distance to earth
ground.

My rig went south and ICOM gave me a new one which has very little of
the self-keying problem.

Overall - the rigs performed well but for this problem. The more
resonant my antenna was, the better the situation with the keying was.
I think that having a balanced with the braid isolated via coiling or
other means would help greatly. You don't want radiation near the
unit, as this seems to key it. I've seen this problem with all kinds
of rigs when mounted in an automobile.

I don't know how they do their inventory, but I've purchased from
them in person twice, and both times preceded the visit with a phone
call to verify the inventory.

The place itself is a nice place to view equipment, and the staff
was very helpful to me personally.

I ORDER stuff from HRO in Atlanta. Never had a problem. Just place
order via phone call and they will verify stock before they get
your card info, or do an inventory search of their other stores and
ask if you want the stuff sent from there.

AES has also done well by me.

Five weeks old and never off my desk. Checked into local
nets 7 or 8 times.Comes to you exactly like it came from
factory.

The Icom IC-703 is an all mode QRP HF transceiver with
built-in automatic antenna tuner and digital signal
processing. The radio was specifically designed for
QRP operation, and features automatic notch and noise
reduction (via DSP), built-in CW memory keyer, built-in
TCXO, multiple scanning modes, and more. The AUTOTUNER
features LATCHING RELAYS to help reduce current drain and
works much better than the average built in tuner.

$600 shipped/insured CONUS.

I asked ICOM today if they were planning on a mod for the 703 and 706 radios to operate
on the new 60 meter band and below is their reply!
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Good Afternoon...

Thanks for your e-mail.

The home company in Japan is aware of the 5 channalized frequencies. At

this time, there are no modifications or upgrades to any ICOM radio that

will allow operation on 60 meters.

Best Regards;

Mike

My first 703 went into Communications Headquarters, Wilmington, NC.
no transmit and keying problems. Got my new one in the mail today,
and am happy with the prompt turn around by Communications
Headquarters.

I seem to be still having the same transmit problems using keyboard
and the CW Type program by UA9SV. I have an optocoupler circuit
between the computer and the rig and I have used it successfully on
my 706 and my Kenwood 450S/AT.

703 is set for straight key. Examples of problems: enter a v and
sometimes it transmits a u or maybe just an extremely long "dah"
If I enter an e, I usually get the extended "dah", maybe 3 or 4
seconds. With other letters I have the same problem.

Using an iambic, or straight key there is no problem. Other than the
obvious solution is not to use the keyboard program, but does anybody
know of a solution to this problem?

Thanks

Hi Eric,

Well, I don't know about the 703, but I have both a 706Mk2 & a
706Mk2G, both of which work just fine on 5MHz.

I used the information at: http://www.mods.dk/ to do the mods.

However, I should say I waited until the warranty expired!

After the mod I checked out both radios using a spectrum analyser,
and all the sproggies are well within spec.

The mod is very easy. The photo shows my IC-703 HF unmodified. All
you need to do is remove the diode circled in the photo. This will
open up the transmit to general coverage. The diodes are located

For the "G" model, I used the third one down - 21.08.1999.

The rig is fine for general coverage HF transmit, but don't try it
out of band above 29.999MHz as the rig has SERIOUS spurious outputs
on some frequencies that will cause BIG problems.

I've used my "G" on 5MHz since last August without any trouble at all.

Carefully try 1/2 wave antenna lengths in your "longwire"(1/2 wave,
1 wavelength, 1 1/2 wave, etc.) for the bands you want to try. or:

Cut your "longwire" into dipole(s) and feed with coax.

OK,

You've bought the rig *and* read the manual? Good, here's a quick test:

On page 72 of the PDF handbook 'Control Command' for Command 16 Sub command
02 I see that the preamp status can be either off (works OK), Preamp 1
(works OK) or Preamp 2 (errors).

What is Preamp 2? When I try to set this via my software I just get an error
from the radio, so I wonder if this is an error in the handbook?

Simon,
The preamp/Attenuator button (page 3) can turn the preamp on, or the attenuator
on, or both off. It would be an error to try to turn both on. I don't see any
reference to the attenuator in the command table.
How is the computer control going? I would be happy to be a beta tester if you
need one.

re. the same 'option' on page 61, but the UT-106 comes standard on the

Not sure why ICOM enjoys confusing folks, but I think the 106 is already

When using my 703 the DSP acts, sounds peforms just like the MKIIG.

Well I just have to say this:

I've been working on Ham Radio Deluxe now for 3 weeks and ICOM's
implementation of computer control puts Yaesu not just in the shade but in
the stone-age. The 703 commands are much better than even the 706MkIIG's.
The rig itself is a stunner.

To say that it is very good is an understatement. It is utterly
professional. It is a real pleasure to write software for the 703.

Anyone wanting to run this software when the Technology Preview is available
in 2 weeks will need a CI_V converter which is available from your friendly
ICOM shop or you can build something yourself. Peter Halpin (outside in a
nice lightening storm as his alter-ego Igor) make me a simple box which does
the trick.

I have a screenshot or two on my website but this doesn't begin the describe
what can be done.

Hi Simon,

Finally did it.. My IC-703 was ordered to day so should have it in a
few days.. I just couldn't resist after hearing all the positive
comments! :-)

It will be very easy getting use to operating as it is much the same
as my IC-746.. As the junior OP put it "looks like the baby version
of the current radio". I'm sure looking forward to the larger display
as the FT-817 is a bit small for poor eyes.. hi..

It will be nice working with your Ham Radio Deluxe on both ICOM rigs.
I have a CI_V cable, so already to go here.. The next project will be
figuring how to use two rigs with the one interface cable, as I do
not have the ICOM interface with multi-radio connections.. It's
really great not having to re-learn everything when changing radios
and/or programs.. I really like that.. hi..

| 263|263|2003-06-30 23:22:06|Patrick STODDARD|WD9EWK - Field Day 2003 @ Flagstaff AZ|
Hi!

For the third year in a row, I made a day-trip to northern Arizona
and operated in Field Day as WD9EWK during Saturday afternoon -
until sunset - from the Fort Tuthill park, south of Flagstaff AZ.
Unlike in 2001 and 2002, I did not use my trusty FT-817 portable
transceiver; I had a new IC-703 (HF only) I wanted to try out in
Field Day conditions, and also try it at 5 watts - the maximum
power level as my FT-817. I was able to compare the 703's
performance to the 817, and IMO the 703 is a better radio for
these conditions. I will file my entry to ARRL shortly, in the
same category as I used in the last 2 years - 1B, 1 operator,
battery power.

My station was not complex - the IC-703 transceiver, an LDG Z-11
automatic antenna tuner with the LDG RBA-1 external 4:1 balun,
and a 40m dipole up approximately 15 feet (4.57m) fed with
450-ohm twinlead to that tuner and balun. My station was powered
by a 12V 21Ah gel-cell battery, and with the radio at 5 watts the
the battery easily ran for the entire afternoon. I had another
21Ah gel-cell, plus 2 other 7Ah gel-cells, that I could have used
if needed. I sat at a picnic table on the south side of the park,
just inside the entrance off Arizona 89A and I-17, and was shaded
by trees that surrounded my table. :-)

I was on the air for just over 6 hours, bouncing between 3 bands
(15, 20, and 40 meters), making a total of 51 SSB contacts in
that time. I was "entertaining" a visitor for a little while in
the afternoon, so I lost some operating time, but still had fun
being 2 hours away from the heat in the Phoenix area. This is
the largest number of contacts I have made in any of my 3
portable/QRP Field Day efforts - I had 47 in 2001 (37 SSB, 10
RTTY), and 36 in 2002 (all SSB), so I am not complaining about
this number. I will also claim 2 of the 100-point bonuses on
offer (operating 100% on battery power, and being in a public
place). I had no luck on 10m, but tried 40m for the first time
in my portable/QRP Field Day ventures, and made almost half of
my QSOs on this band. My 51 contacts were with stations in 10
US states (none east of Texas - heard the east coast later in
the day - but they didn't hear my 5 watts), 2 Canadian provinces
(Alberta and British Columbia), and 19 ARRL/RAC sections. Had
I run more power, or set up somewhere I could operate well into
the night, I know I could have done better - but this was an
enjoyable afternoon no matter where my score ended up.

I bought a disposable 35mm camera to take pictures of my setup,
and need to get that developed and scanned into JPG files. I
will post them shortly on my web page for this Field Day effort
at:

http://www.qsl.net/wd9ewk/fd2003.html

I like the 703's receiver, and even at 5 watts having the speech
compressor in the 703 helped me out. I could have done better
at 10 watts, but I like this category despite the lower power
level (love that 5X power multiplier!). This radio, along with
the Z-11 tuner, will definitely go with me on other trips in the
future.

Until Field Day 2004... 73!

A bit over a week or two ago I posted a question to this group
asking if anyone had been experiencing a "runaway keyer" with their
703. I didn't receive any answers right away. Basically the 703's
keyer would become unstable on some bands (I experienced it on 30M
initially) and insert it's own dots and dashes. I checked my
grounding and antenna resonance - all ok. Thinking about it, it
seemed to me that RF was getting into the keyer, most likely from
the wire leading out to my paddle. Ground should be ground within
the radio, so I figured that if there was a "floating ground" issue
associated with the keyer, that could be the problem. So, I took a
short length of wire and soldered it to the ground lug (male end) of
the keyer phono plug and fastened the other end to the chassis
ground lug on the back of the 703.

Bingo - problem cured. A few days ago a gentlemen on this group,
Dennis, emailed me and wanted to know if I'd found a cure. I told
him what I'd done and he tried it. He reports that it fixed his
runaway keyer issue to. He was more curious than I and he added
that his measurements between the keyer ground and the chassis
ground was around .8 ohms. That would be enough to cause stray
currents.

I'll zap Icom a message and see if they say anything and report back
to this group if they add anything. Until then, this 'lil fix may
help any others here thay may be experienceing the runaway keyer
problem.

Bob,

I believe most of the big dealers are running neck-to-neck. The only real
price difference I've noticed is in accesories. AES wants $20 more for the
500 khz CW filter than Universal Radio.

If you do a search on the IC-703 in Google you'll hit all the Ham vendors
websites with (most likely) links/urls to there price pages for the radio.

Hi Eric!

It probably could have, but the Z-11 has a wider matching range
than the 703's tuner - wider than even the range published in
the July QST review. I also had the tuner with me in case I
had to revert to my FT-817. Once I tuned up on a particular
band, I would turn off the Z-11, since it will hold its settings
without power.

One reason I bought the 703 was so I wouldn't need another box
(external tuner) when working with less-than-ideal antennas and
away from home, but for Field Day I had lots of room in my car
to haul stuff with me. There will be other trips - by plane -
where I won't have this "luxury", and not having to haul stuff
like an external tuner will be very good!

Band conditions were very poor with few station being heard at my
QTH. I heard a W7VJ calling CQ and gave him a call. I was almost
surprised when he came back to me. With his amp and stacked beams, he
was the strongest sig on the band, 59+. His antenna system did it's
part to help me out but still I was impressed with my 54-55 report,
running 10 watts into a ground mounted Buttermut HF5V vertical.

The DSP noise reduction and noise blanker work great. All controls
and functions are easy to figure out. Excellent sensitivity on the MW
broadcast and LW bands and the pre-amp works if required.

Over all, I'm impressed. In some ways it seems to work better than my
IC-746 but more tests need yet. This one looks to be a keeper... now
is anyone looking for a very slightly used FT-817.. :-)

I just put my Icom703 into service and the transmitter did not
work. First time I have had an Icom (I own a 706 and have owned many
others in the past) fail out of the box. Sent it off to Bellevue and
hope for a speedy return.
Listening around with the radio was great, but I am anxious to
actually get on the air with it.
| 273|272|2003-07-08 05:37:25|Bob & Janet|Re: Icom 703 Transmitter problems|
my IC706mk2g failed out of the box. It would heat up and quit... just the
heat from receiving was enough to cause it to shut down.

Icom found a bad/cold solder joint.

Hi all,

I have just got my '703 back from repair after a failed PA stage. It
took two weeks to get there and back, but that's including shipping
it from the Netherlands to the UK and return - that's reasonable
service. It's all working according to expectations and I am able to
press on with testing Ham Radio Deluxe. I've already found a few bugs
that weren't apparent while using a mate's 706MkII (tnx PE1OQX!) and
things are coming together quite nicely. We can expect a "technology
preview" of HRD some time towards the latter half of next month if
things go according to plan.

My new IC703 was just delivered by the big brown truck WIIGII

I have noticed immediate questions - perhaps I did not read closer, but I
thought that the IC703 had internal battery or is it just that it knows to
cut back output power when EXTERNAL battery voltage drops...

And the big question... does anyone know a secondary source for the power
cable? Before I cut this cable to install Anderson Powerpoles, I would like
to know a source for the orginal style connector (and why did Icom use an
entirely different connector from the series they normally use - who was the
idiot that decided to change?)

The connector is man enough for the job: my FT-1500 has a very similar

Power Poles is the dreaded "Not Invented Here" syndrome?

Hi Bob..

Glad to hear it got there OK.. bet your having fun now! hi..

Looking at the power cable, there are only two wiress, so there is
no way the radio can tell what power source is being used. It thus
assumes you are on battery when the voltage is around 9.6V. I guess
the reason for this is that most people running from a power supply
would likely have 12v or better, so why run it on lower voltage..
When I turned down the voltage on my PS, I was a bit surprised to see
low voltage battery flashing on the display.

The connectors will likely become more readily available later. I
think I will cut the cable and worry about getting more later.. On
the positive side, I sure like it better than the power cord setup on
the FT-817.. Icom gave us "a real power cable"! :-)

Hi Ken,

Well, I tested the IC703 to make sure it worked (not a DOA/ out of box
failure like my IC706mk2g was), then I carefully removed the orignal
connector from the radio. I removed the pins from the white shell and then
removed the wires from the pins... I then SAVED the pins and the shell for
possible future use (why I do not know, these connectors are trash - yes,
better then the FT817 [now that connector is a joke on ham radio] and the
Powerpole is a far superior connector!). I then opened the radio, found the
tiny chip resistor and opened the TX so I can play on 60m.

I then put it all together in my WorldPak2, and when this thunderstorm
quits, I am going to go play radio - outside, with my AS1887 mil surplus
whip, but if it never stops raining, I might just finish my CT17 project.

Here are some instructions for modifying your IC-703 for 60 meters
Transmit. Also, it will transmit elsewhere, so be careful after you
perform this mod! First – carefully remove the face plate from the
radio and put it aside. Look at the instructions in your manual,
page 68 and remove the NINE screws holding on the TOP COVER. Use a
piece of plastic to slowly force the top cover from the radio. BE
VERY CAREFUL when you remove the cover as the speaker wire is
connected, via J 7372. Remove the speaker wire from the connector
and set the top to one side. Now, look at the instructions on page
68 in your manual - that shows you how to install the UT-102 Voice
Synthesizer unit. Notice the outline of the UT-102 unit on the
photo and now find it on the radio's main board. On my main board,
right below the WHITE, 8 pin UT-102 connector it says "UT-102". You
will need a magnifying glass to continue.
Note: the UT-102 lettering is almost on the front edge of the
circuit board.
You must now count solder pads to the LEFT of the "U", (UT-102) and
the chip you want to remove is on pad 6. Also, there are only 13
pads to the left of the "U". Of the 13 pads, only FOUR of them have
chips across them. The chip you want to remove is on pad 6.
Another way to describe that chip is that it is the SECOND chip from
the LEFT of the "U" on the circuit board. I just lifted the front
of the chip off the pad and left it attached to the back pad. That
way it can be put back in place, if needed.
Please, Please – these chips are very tiny, so take your time and
use a small tip on your solder tool to unsolder the chip. If you
feel uncomfortable doing this mod – DON'T DO IT!
There does not seem to be a way to post photos in the photo section
of this group, so – if you want a photo of this mod please contact
me at rllaffoon@... and I will send you a JPG photo that
has a hand drawn RED arrow pointing to the chip that has to be
removed or lifted on one end. It is a very clear photo. Also, on
that photo I moved the GRAY wire that crosses to the right of the 8
pin White UT-102 socket, just so that I could take the picture. It
might be a good idea to move the GRAY wire out of the way while you
do the mod. The GRAY wire does not unplug, you just have to
temporarily re-route it.

Hi Larry and the group..

Here are a couple of thought on the mod.

1)- It may be a good idea to use a soldering iron with a grounded tip!

2)- For those prefering to avoid the soldering iron.. Use a razer
blade kniff and carfully cut out a sliver of the pc board trace
leading to the cap.. that way the cap also stays in place. Best of
all there is less chance of damaging something else. If you should
ever want to undo the mod, just place a solder bridge across the gap
you made in the trace.

Hi all,

I used to have a plain vanilla IC-706, and I have been using a
friend's 706MkII for testing Ham Radio Deluxe - both of these had
quite "loose" VFO tuning knobs if the brake was fully released. My
703 is quite a bit stiffer, and won't move more than 3/4 of a turn
even if given a good swing. Does anybody have an idea how to remove
the tuning knob without busting something? Is this a standard feature
among 703s?

I have looked for HRDeluxe and I cannot find it, does it exist yet, is it
vaporware? I went to Simons site and followed the links to download HRD, but
there was nothing to download.

Yes, I saw the notice about his biz manager and the delay, but from all the

Hi Bob,

As Peter says it does work, it isn't vapourware and it will be free. I have
some things I want to do before I make a technology preview available, my
business partner who died left behind an excellently organised business and
I'm finding it very painless taking over the administration although it's
also very sad. Fortunately running a business in Switzerland is not as
complicated as in some other countries.

Despite the additioninal work my partner's untimely death has caused I think
we'll have something available as Technology Preview #1 in two weeks, if you
look at the screenshots on the webpage you'll get an idea of how it's
shaping up. To be honest what Peter and I are using is very usable for the
IC-703 and IC-706, I've been enjoying using it with my IC-703 and have had
quite a few 6m contacts while driving the rig via the software - AF gain, RF
gain - all I've done with the rig is press in Power button, everything else
has been controlled via Ham Radio Deluxe.

A sign of how well it's going is that I haven't had a bug report from Peter
for two days! The first preview will support FT-817, FT-857, FT-897 and
IC-703, IC-706, IC-706MkII and IC-706MkIIG. I have promised Peter that as
soon as this is out I'll try to add support for the Elecraft K2.

Please bear with me - the FT-817 Commander and other programs show that I
can deliver the goods, even if there are some bugs.

add, and it's bound to go wrong somewhere :-) The real test is when the

all. NEVER underestimate the power of a user to REALLY screw things up....

comparing the rigs, I don't find the IC-703 to lack anything. The DSP
and speech processor work very well. Also, the antenna tuner has a
wider range and allows me to use antennae that the IC-746 will not
tune. The only complaints I have heard are from CW OPs.. The say the

Hi,

From memory adding initial support for the IC-746 is not difficult. The
program is data driven - for each radio I have tables of buttons, commands
to set / get values etc. I don't want to make it user-customisable yet but
adding a new radio is *very* easy for me. I may look at the 746 CIV commands
before the Tech Preview.

I live at 1,050m asl in the Swiss Alps (see my website) but have worked most
of Europe on 6m - when it's open it's really open.

the FT-817 has are:

* 2m + 70cms
* Smaller package if you are going backpacking

Hi all,

Adrian asked:

It's not a fair comparison: I reckon they are aimed at two different types
of user.

I have owned an '817 and had an enormous amount of fun with it, but the '703
has a far superior receiver - and that gets my vote any day of the week. It
also has a built-in ATU and a neat DSP noise reduction. The downside is that
the 703 is larger and heavier than the '817 - but isn't everything? Of
course, you could consider building an Elecraft K2 :-) Mine knocks spots
off almost everything when it comes to receiver performance.

If you need an "everything in one box" solution, then go for the '817. If
you need a good receiver (and you do!) that's solidly built and is easy to
use, go for the '703. But whatever you do, build a CAT interface and get
FT-817 Commander if you buy an '817, or wait a short while until Simon
HB9DRV gets Ham Radio Deluxe up and running. Testing is proceeding quite
nicely, thank you very much. Have a gander at http://www.hb9drv.ch and

I would go for the IC703. have had a FT-817 and had lots of fun with the
thing.

Now I have sold that one and working my way trough QRP-QSO:s with that
and QRO QSO:s with a FT-857.

The altter is really a QRO version of a FT-817 with all the quircks
solved
plus adding a bit mor power.

I´m waiting for YAESU to come out with a FT-817 mkII having the
following
bits done although having the same size:

Both antennaconnectors on the back
A bigger display being possible with removing the front antenna
connector
Using the space used for batteries for a autotuners with a 1:3 range.
Speecprocessor built in.
Option for 2 proper filters ( CW and SSB )
Bracket on the bottom to lift the rig when being put on a desk
QSK

There we go FT-817 is a great TRX but IC-703 outperforms it now
although the size of the FT-817 is great also having the option to do
2m and 70cm when being on the road.

The advantage that I like is the remote head. I operate with the rig secured

well, my /pm set up is still a "works in progress", but it is a WorldPak2
case. The WorldPak2 is attached to a GI surplus ALICE frame.
The pack needed to be modified by adding D rings to the top and sides so
that it could be attached using black tywraps.

Look at my web site for pictures... http://users/adelphia.net/~m10 if the
pictures do not show up OR adelphia is DOWN AGAIN! try www.qsl.net/k8ys.

Follow the links to Amateur Radio. I have pictures of the FT817 in the same
configuration.

The WorldPak2 case has a large pocket in the bottom. This pocket is PERFECT
fit for two 4AH/12v gelcells.

I mounted a "mirror mount" 3/8x24 antenna base to the ALICE frame. From the
antenna base, I added a short pig tail from the mount bolts to a Anderson
Powerpole so I can connect a counterpoise.

The radio connector has been replaced with an Anderson Powerpole. Red, Black
and Orange. Red and Black are obvious, the orange is connect to the
ground/earth bolt and goes out of the pack to the antenna base.

I already own an IC706mk2g and the separation kit. I have never mounted the
radio in the van, so I have never used the remote kit. I took the remote kit
cable and connected to the radio, place the radio in the pack. I can now
button up the pack since I no longer need to get access to the front panel
or antenna tuner - as I had to with the FT817.

Antenna is a special/rare critter. It is a GI surplus AS/1887 for the
PRC1099 or the PRC77. I am not sure exactly which. The antenna covers 3 to
18 MHz with a tapped coil. To change band segments, you move a tap at the
base of the coil. The antenna whip is a LONG sectional whip that looks like
a modern tent pole -- the type with an elastic string down th emiddle so you
can fold the tent pole - or maybe a blindman's cane.

I have made two contacts on it so far. My first contact was on 10m with a
mobile station in West bygawd Virginia. I then tried 20m and 20 was a
pitiful mess, but I worked the MM net control. I am in Ohio -- 26m N of
Cincinnati, 12m S of Middletown. The guy I was working in WVa did not
believe me that I was WALKING around the yard with the radio.

Unlike the LDGz11 tuner, I MUST use a counterpoise with the internal IC703
tuner and the mil whip. The z11 did not much care what I was trying to feed,
the IC703 is VERY selective!

Oh, the nice thing about mil surplus... I can add battery packs, 4AH/12v at
a time. A battery fits perfectly in a 20 round M16 ammo pouch, and the
pouches are made to fit the ALICE gear.

My plans are to put the radio gear inside the MEDIUM ALICE pack if I ever go
out needing overnight or a couple nights worth of gear/clothes. The medium
pack fits the frame and has an internal subsection made to install radio
gear.


Did I miss anything?

Hi Adrian and others,

One thing I forgot to mention is that the '703 has a TXCO - fitted as
standard - for added stability. That's worth taking into
consideration.

No one seems to have mentioned that the 817 can, of course, have an internal
battery fitted for ultimate portability. This is how I use my set.

This is the major disadvantage for me when considering buying a 703 as I
would have to use an external battery.

OK, the 817 doesn't have a built-in ATU but as I use pre-cut dipoles "in the
field" I've never needed one. I think I would also miss 2m and 70cms as
well.

I think the point raised earlier that the two sets are targeting two types
of operation (and operator) is valid, so perhaps a comparison is not
ultimately relevant.

I agree the 703 is a nice set and has a good receiver and features but at
the high prices charged for the set in the UK (especially compared to the
US), I think I'll give it a miss for now.

Hi Adrian,

I have both and would very strongly recommend the 703. The advantages that
the FT-817 has are:

* 2m + 70cms
* Smaller package if you are going backpacking

In my opinion the 703 is much better thought out, the receiver is excellent.
The main 703 advantages:

* bigger display
* better menu system
* better RX
* built-in ATU
* DSP - very good indeed

I think this is question that will keep poping up so I've taken the
time to put down some of the pros and cons of both radios from what
comes to mind... These are of course from my experience. Others may
have some additions or different comments based on their own
experience.

IC-703 vs FT-817
+++++++++++++
IC-703 pros
=========
Front face can be detached for remote use or mounting
Large Main Tuning Knob - very easy to tune
Large easy to read Display
Very easy to use Menu System
Built in Auto Antenna Tuner
DSP noise filtering included
Speech Processor included
High stability TXCO standard in some versions
Has a "real power cable" with fuses
Memory Keyer
Accessory plug with pig tail wires is included
10 watts power output
9 - 15.87 volt operation with microprocessor power save
Wire "stand" to hold up Front of Radio
Price The Same or Less than the FT-817 (in my country)

IC-703 cons
=========
CW OPs have complained about the QSK
CW OPs say Optional CW Filter is a necessity
No Internal Batteries
No 2m + 70cm
Large Manual Size (not convenient for portable)
Size and Weight for Portable
No Schematic included

FT-817 pros
=========
Very Small Package
Designed for Portable Operation
Shoulder Strap for Carrying is included
Internal Batteries (may not last long)
Included 2m + 70cm
Front (top) and Rear Antenna connectors
Rubber Duckie Antenna for 6m, 2m & 70cm
Small Manual Size (convenient for portable)
Schematic included

FT-817 cons
=========
Display is very small (especially for old eyes)
Main Tuning Knob - very small (hard to tune)
Buttons and Menu system can be confusing
No - DSP
No Auto Antenna Tuner
No Speech Processor
No Keyer Memories
High stability TXCO Costs Extra
No Wire "stand" to hold up Front of Radio
Maximum Power Output 5 watts

Above are some of the points that come to mind, from using both the
FT-817 and IC-703. After getting my IC-703 I it didn't take me long
to decided which radio to keep. I wanted the extra features that I
was use to having in my main rig, an IC-746. I found the IC-703 to be
as good and in some ways better than my IC-746.. For one thing, the
ATU will match an antenna that the one in the IC-746 will refuse to
tune. I like the "Big Radio" features in this small package, the
larger display and bigger tuning knob that I can easily spin with my
finger.. I was use to using a Icom IC-746, so I found it much easier
to get use to operating the IC-703.. I only need the manual to
refresh my memory on a few things. As to portable operation, I have
no plans to climb a mountain or go any other place that that will be
very far from the road or parking lot so I can carry my gel cell or
what ever when required.

To be fair, a whole lot will depend on how you plan to use your radio
and where you plan to take it. If you are a real out doors person
climbing mountains etc you would like the small size of the FT-817.
For general operation or a beginners rig, there is no way the FT-817
can compete with the IC-703.. both radios are in a different class! I
had fun using my FT-817 and made lots of contacts. the radio worked
well and did what it was advertised to do. Very impressive for the
sizr of the package, complete with 2m + 70cm, making it an all in one
radio. For me the display was far too small for my "old eyes". I
really had no need of the 2m + 70cm as it is easy to carry my small
VX5-R if those bands are required. I have no regrets with selling my
FT-817 and love my new IC-703..

Feel free to add you additions to this list, I'm sure I forgot or
mixed up something in the process..

Hi,

A few comments: the IC-703 manual is available as a PDF so you can print it
out yourself on smaller paper for portable use.

For portable use although the FT-817 has internal batteries the current
drain is roughly similar to the IC-703, and after you take into account
everything else you'll need the extra weight / volume of the IC-703 isn't
such a problem.

Hi all,

Ken mentioned:

But the same can be said of the '817!

I doubt very much if the schematics are any use to "Joe Average" anyway -
even I feel rather insecure about poking around inside these SMD rigs :-)



You call that a PRO? A rubber duck is by definition a con, isn't it :-)


Is that a con?


Agreed - an amazing little rig. If Simon hadn't decided to do Ham Radio
Deluxe I would still have mine - but I am glad that I "discovered' the 703.

And an Elecraft K2 is still a very viable option - it may cost more, but
just look at that receiver! AND you have to build it yourself...

| 314|301|2003-07-12 12:46:17|Al Bolton|Re: Icom 703 vs FT 817 - Pros and cons|
The current drain is not too big a problem if you use CW as I do nearly
exclusively and use a high cpacity NiMH pack.

A spare battery pack is not as big as even a small Gel cell battery either,
so I think the 817 is a better portable choice for me-for now!

Hi Bob and the Group

Thanks for your very informative post. You clearly have spent some time
thinking things through.

Congratulations on your workmanlike /PM arrangements.

Provided antenna impedances are kept within the 703's autotuner range I
think the 703 is going to prove a hit for this market.

I will be out /PM from about 1600Z today (with the Alinco at 50W). Hope to
join the HFPack net on 18157.5 1630Z. Hope the band is in a lot better
shape than yesterday. If it isn,t I will be on 40m.

What antennas are used by the group. With my SG 2020 I've used either
the Buddiplole or a 44' dipole fed with twin lead through an LDG Z 11
tuner. I purchased the 703 because of the built in tuner. I operate
mostly in conjunction with my scout troop camping trips
| 319|319|2003-07-14 17:02:43|Larry Laffoon|Re: Digest Number 86|
Hi Ted - I have used mostly Dipoles and a Beam antenna so far - all of which
the built in tuner handle just fine. I have an LDG RBA-1 which I plan to
use with a long wire antenna sometime soon. I will report to the group on
how that goes, should be fine. If you use "twin lead" you should use the
RBA-1 as it is a 4:1 balun and should do the job without damaging the
internal tuner.

I use the Commercial Buddipole with my IC-703+. I tune the CBP to 17 meters
and operate 20-17-15 with the tuner in the IC-703+. Works great for me.

I will be using this combination on Grand Cayman Island from August 5-11 as
ZF2FF. I plan to be on every morning and some afternoons and evenings.
Please look for me on 18.157.50 SSB and 18.080 CW as well as 14.342.5 SSB
and 14.050 CW if 17 meters is dead. I will be on 50.110 off and on as well.

Maybe someone ought to ask ICOM? I'm guessing it's a software
leftover from the 706MKIIG code they used. The coders probably
didn't do their homework and left that portion of the code in place.
By the time it got to a point in pre-production and caught it was
decided to leave it be and put the responsibility in the users hands
as to use that feature or not.

Just a guess... the transverter theory is a good one too!

Hello everybody!

I would like to invite all of you to give the best solution for a home made NiMh Battery pack (but easy to handle, without too much fuss)

As I can see, there is no commercially available NiMh battery for this radio...yet. It would be nice to put together a battery pack worth at least 4000mAh,...with 9.6v.

Maha comes to my mind,...but they still don't have anything particular for IC703.

Have a great day!

I've had good luck using the Radio Shack 1600ma/9.6v RC battery
packs and the Radio Shack fast 5hr. charger. I use two of these
packs, replacing one as it gets depleated. There is certainly no
reason why you could not connect two or more of these packs in
parallel to boost the current capacity.

An even better option for me is laptop computer Lithium Ion
batteries. I've been recently using a very lightweight laptop
battery with a capacity of around 3200ma at 12v. The same Radio
Shack quick NiMh charger seems to charge this battery fine with no
problems noticed.

Although LiIon packs are, usually, internally protected these days
they need to be used with suitable chargers designed for charging
this chemistry. I am not familiar with the Radio Shack charger but
recommend you check its suitability (a) for your own safety, and (b)
to check that you are not overcharging the pack and thereby
degrading its capacity or longevity.

Dear All,

Having just joined the IC 703 group, I'd like to say hello to everyone. I am glad to be here - and I've already got some questions on this rig (which I ordered a few days ago; strill waiting for the mail to arrive):

I downloaded the instruction manual. The manual says on page 7, section 4 on installation, that the internal ATU is designed to work with an unbalanced 50 Ohm feedline and will not operate with a long wire or ladder line. If this is the entire story of the ATU, then the rig is not fit for qrp purposes. Most qrp-ers I know work with some kind of a wire antenna. I just finished making myself a new G5RV and I would like to use it with the IC 703. In light of the above instruction, I do hope that the ATU will work properly if I put a BalUn between the antenna and the ATU, connecting the BalUn with a few inches of RG 58 to the ATU. Will this work??

And there is another remark on the same page of the instruction manual which puzzles me: it says that you cannot use the IC 703 with a magmount antenna. I am not sure if I understand the term "magmount" correctly; I always assumed this word refers to the antenna installation on the roof of a car usig a magnet antenna mount. Is that correct? And if so: why shouldn't we use such antenna with this rig? What is the problem with the mount?

Actually, both questions boil down to one issue: if you are neither supposed to use an unbalanced feed line nor a removable car mount, then the only antenna system you are supposed to use is either a a large gp or rooftop antenna / beam (great portable perspectives) or a whip antenna nailed to your head. (ok, the buddypole would probably work , too ...)

But I guess I misunderstood something here and I hope some of you might have good news for me ...

Tnx es 72 de DL5OA, Alex

Hi Alex,

The ARRL report said the tuner is about an 8:1 range tuner on resistive
loads, which is pretty close to the the 10:1 LDG tuners. I have used the
tuner to match a 40 meter quaterwave vertical on 80 meters. I also used it
to tune hamsticks over a full band with a counterpoise.

So I think it is a bit better than ICOM's manual implies.

I have not yet tried a 40 meter doublet fed with 300 ohm line via a balun.
But based on other tests it should tune a G5RV just fine, especially if you
used a balun on the feed line.

A mag mount does not actually connect the shield to the car body so there
is no counterpoise so to speak.

my turn for a question... I have the programing cable for the FT-50,
I need a programming cable for the Icom. After looking at the
schematic, they are pretty much identical, they both take serial data
from the computer and convert it to serial data for the transceiver
(basically RS-232c to TTL). The only difference that I see is the
connector. The FT50 having a 4 circuit mini-phone jack and the
IC703/ic706 having a three circuit mini-phone jack -- and to top that
off, the FT50 uses an adapter between the yaesu cable and the ft50
adapter!...

I am wondering out loud... are they compatable, without the need to
build a new level converter for the IC703????

Maybe, all I need to go between the FT-50 and the IC-703/706 is an
adapter between the end of the Yaesu cable and the Icom CI-V
connector???

Suggestions anyone??

Right you are about being careful with charging Li packs. The RS
charger has an internal timer that limits the charge time to the
battery. I also like to keep an eye on any fast charging process to
make sure the pack doesn't heat up. With this particular battery
and charger, everything is cool as a cucumber. But again, keep tabs
on any fast charging process just to be on the safe side.

When I bought my 20m hamstick and mag mount at a hamfest a few months ago,
the dealer advised not purchasing the single pad mag mount as he predicted
I'd just take it home, find I could not load it properly and return it to
him. He said that the single pad does not provide sufficient capacitive
coupling to the car body to provide a suitable counterpoise.

Instead he recommended the three-pad mag mount, which I subsequently
purchased. I can't say for sure if he was right about the single-pad mag
mount not working, but he was certainly correct about the 3-pad mount
working ok. It certainly does.

Measurements with the MFJ-259b antenna analyzer indicate an SWR of 1.1 : 1
(f=14.2 MHz, R=46 ohms, X=5 ohms.)

The 703 loads it fine and in the SWR display shows it as one LCD segment up
from 1:1.

Yes indeed! They seem to work well enough for VHF/UHF - and I even used a
5/8th for 2m as a 1/4 wave on 6m without any problems, but on lower bands
they are a little iffy. You really can't beat a PROPER mount with really
good grounding. And if you put a mount on an body panel that's hinged (like
a boot lid - trunk for those of a colonial persuasion) make darn sure that
there's a SOLID electrical contact between all panels and the main frame of
the car. RG213 braid can be used for this, although there are good grounding
straps available at most automotive electrical stores.

Hi.

I use the four pod/magnet mount (with a cut down placemat to protect the
car roof) for my hamstick on the car and a counterpoise when hiking. I was
thinking the single pad mag mount - should have said something abou the
multi-magnet ones.

Hi,

Does the 703 have PBT? In the CAT codes (user guide page 72) I can set the
inner and outer PBT but they don't do anything and I failed to find PBT info
in the user guide, so I'm wondering if this is an error in the CAT codes
table.

I have found a few other errors so I'm guessing this is an error but it
could well be pilot error :-)

Hi Tom,

thanks. Well, I guess if you connect the shield of your coax at the
base of your antenna to the car frame, any magmount should work with
the IC 703. Thanks also for your encouraging comments on the G5RV. I
can't wait to try the rig (hasn't arrived yet).

There have been a few reports of low output, but all have been fixed

with a full replacement from ICOM. Hopefully someone will comment on here
but I recall reading something about a bad solder joint and erratic keyer

Just my 2 cents on what I've done with my 703 and G5RV Jr. so far.
I'm hooked up to a G5RV Jr. that is 19 feet off the ground. It
tunes full band at 1.5 SWR or better for 10, 12, 17, and 20 meters.
On 6 meters I loose SWR around 50.300 and down but above that tunes
great. It doesn't tune 15 at all, same results for any portion of
30 or 160 (duh!). However I do get about the top 3/4ths of the band
for 80. I dont' remember where the cut off for the SWR going down
the tubes is. I took a lot of readings and have a lsting of them at
home if anyone is interested in the results.
I've got limited space to put an antenna up at the house and the
G5RV was just a little too long and tough to get high enough up.
The apex of the house is about 19 feet so it was perfect for the
Jr. I've been really satisfied with it. Enough so that I have
another Jr. that I am going to be using as a camping antenna, if
this blasted rain ever stops!
BTW, in the above readings I am not using a balun, it's coax off the
bottom of the ladderline straight to the radio.

Hi,

Is anyone out there using the 703 with CW and using features like the
present number, count-up channels etc.? I'm starting adding support for
these to Ham Radio Deluxe and don't quite understand it.

How does the preset CW number work? And the three channels MK1 to MK3? I
know there's a manual but if anyone out there has figure it out please give
me a shout. I'm out tomorrow...

Hi all,

Ever so slightly off topic - but still useful to know.

And that's the way it should be done! I was speaking to Louis Varney some
years ago at a GQRP Club meeting and he was adamant that you should NEVER
use a balun with a G5RV (he wasn't happy about connecting coax to it either,
as his design assumed the use of 75_Ohm flatcable attached to the open line
portion). If you must use coax, just make an HF choke by wrapping the coax
6-10 times around your hand at the feedpoint.

| 366|337|2003-07-30 20:34:13|areandae|Re: IC 703 antenna sytem and ATU|
As far as my understanding goes, the G5RV Jr. is what I've learned
as a half length and height G5RV. The standard G5RV is 102 ft.
total between the dipole arms and I think 34 ft. of ladderline. My
Jr. is half that. I've only used Juniors but my understanding is
that a full size works better with 40 and 80, with less acceptable
results on 6 and 10. There are also some people who run a doubled
G5RV, mainly to get acceptable results on 160, but with the 102'
being a little more than I can put up, 204' is out of the question.
I think that either of the large two would be a bit bulky for most
backpacking or car camping situations. Not only the transportation
and setup would be tough, but alot of times I can't spot an easy
102' run that I can string up and get 34' off the ground. But I'm
rather new to ham radio and more often wrong than not! :)
Anyway, when I get home tonight, if I'm online I'll send another
post with the actual results across the bands that I've gotten with
the semi-permanent mounted Jr. at the house.

Hi Folks,

I'm having problems with my brandnew IC 703 and I hope someone in our group might be able to help me:

I work almost exclusively in CW and I never use anything else but the good old "handle key". So this past weekend, I put the 703 to work for the first time and followed all steps according to the instruction manual (including, of course, switching "CW paddle" from "on" to "off", as rewuired if you use a morse key). I connected different antenna types, including an MP 1, a DB Sloper and a G5RV. What a disappointment!! First of all, the internal tuner tuned almost nothing. All of these antennas have been in use for quite a while with other transceivers and tuners (even the MP 1, when I was too lazy to tune the coil by hand) and always worked fine. But the IC 703 was hardly able to tune any of them. In most cases, on most bands, it just said "beep" and showed a very high SWR. It did neither tune successfully nor try for 20 seconds to tune before it gave up, as described by the manual. In a few cases, though, it did tune - and then something extraordinary happened: when I started giving
CW signals and pushed the handle, the tranceiver wouldn't stop transmitting after I released the handle of the key. It just gave a continous "dah" without stopping, even if the tuner was turned off! On and on it went until I changed the band or the mode!! I tried various morse keys which I have been using for years, to make sure it was not the fault of the key. This happened many times.

Now, before I send the IC 703 back to the dealer for repair or exchange for a different IC 703, I would be very interested to know if there is anyone am,ong the group who made the same or similar experiences and found a simple explanation; maybe I AM doing something wrong (though I checked all options that crossed my mind).

Thank you very much and

73 de DL5OA, Alex

Hi Alex,

I think you are getting RF into the rig, either via the power supply cable
or via the key's cable.

I would try with a dummy load before sending back.

If it is an RF problem then a couple of ferrites should solve the problem.

Hi all,

Alex wrote:


Icom specify the tuner as working between 16.7 to 150 Ohm (less than 3:1
vswr) on HF bands and 20 to 125 Ohm on 50MHz. I very much doubt that an
untuned MP-1 would meet these criteria :-)

I have (among others) a low-slung 1/2-size G5RV up at the moment, and the
703's internal tuner will give an acceptable match on 40m and up. The actual
SWR on the line is quite a bit higher than 3:1 on 15m, but the tuner seems
to manage. It will even give a good match on 6m. For use with random wires
and such you'd probably be better off with a Z-match - or try one of those
"Magnetic Longwire Baluns" with 12.5m or 25m of wire. You can buy one for
about e75 - or build one for e10. The core to use is FERROXCUBE, type 3C11.

Hi!

I have the same problem with the keyer (using a hidden antenna without of 10
meters of wire), I have solved it inserting a ferrite choke in the connector
of the key. It seems that the keyer this not well isolated of the RF, if you
use the connector of the mike to connect the paddles he won't give you any
problem of feedback of RF.

Regarding the ant tunner, I syntonize the wire antenna correctly connected
directly to PL, even without using counterpoise, in the bands of 40 17 15 12
and 10 meters. (the swr without tunner is between 2.5:1 - 5:1)

Greetings

Alex,

I had the same problem and posted a notice here under "Runaway Keyer."
Seems the ground side of the keyer/key phonojack is not a chassis
ground. There are two surface mounted components that actually rise the
potential to around .6 to .8 ohms. To see if this is your problem, take
a wire from the ground side of the keyer plug and route it to the
chassis ground lug. Should clear the problem. And youdon't have to open
the rig's cover. However, when I modified my 703 for 60 meters, I
lifted the circuit board and tacked a wire to bypass the two surface
mounted components that are between the keyer ground and chassis ground.
My 703 is working fine now.

I sent an email to Icom support regards this issue and they confirmed
the different potential between the key jack ground and chassis ground,
but they didn't think this should be a problem. I have to differ
with'em on this one, though.

I just returned from Grand Cayman where I operated my IC-703+ and
Buddipole antenna from the parking lot of the Holiday Inn. I worked
many stations including Northern Ireland...not bad on ten watts and
a portable dipole antenna only eight feet off the ground. I carried
the 703 in my Icom back pack and went through five security
checkpoints at the airports. Not one of them asked me to open the
back pack to see the radio. They all ran the back pack through the
x-ray machine and off I went. No problems, no questions.

thanks for your replies. I have to admit my ignorance: I am a lawyer and my practical knowledge on technology is very limited. What dou you mean by "If it is an RF problem then a couple of ferrites should solve the problem."? What should I do? David suggests to insert a ferrite choke into the connector of the key, but I don't know what this means.

I wonder if the problem really has to do with getting rf into the rig or the keyer not being grounded to the chassis, as Craig suspects. The point is that the continous signal (this gives CW a new meaning, hi) which continues even after I released the key only appears once the rig is properly tuned, i.e. when there is very low SWR. While tuning, or with a high SWR, the phenomenon does not appear.

I know that my knowlege on technolgy is far below the standard most group members have, but I hope my questions are not too ignorant ...

I would be glad for further ideas.

Tnx es 73

Simon Brown <simon.brown@... Hi Alex,

I think you are getting RF into the rig, either via the power supply cable
or via the key's cable.

I would try with a dummy load before sending back.

If it is an RF problem then a couple of ferrites should solve the problem.

I don't have a 703 yet, but I have been following the various 703 forums
as I decide to buy one. Yes, I have seen several posts about RF current
on the key line locking up the rig in continuous output.

The most probable cause of the continuous keying is some amount of RF
current imposed on the key line. This current can come from either
direction.

Even if your antenna shows a match, there can still be RF current on the
shield side of the transmission line which can than flow though the key
line to your key to your hand, through capacitance between the key and
your hand.

Or, the RF current may be radiated from the antenna and picked up by the
key. I'm going to guess that your problem is not this mode unless the
antenna is physically close to the key.

There are several ways of removing the RF current. You can get some
ferrite beads, see FSB-1/4 and SBC-1/4 on the Palomar page
http://www.palomar-engineers.com/Ferrite_Beads/ferrite_beads.html, on
your transmission line to remove the RF current from going down the
transmission line shield to the radio. Where to place the beads is a fun
thought, probably at the antenna connection point. Somewhere on the
Palomar site is a discussion page about RFI.

Or place the same beads on the key cable to remove the RF current on the
key line.

You can also try to shunt the RF current on the key line by placing a
small capacitor, .01 or .001 uf, between the pin and shield. I saw
something about the key shield being above ground by some small
resistance, so don't know how well this may work.

I hope that this helps some.

The more I think about this, the more I am convinced that this key lock
problem is caused by to problems.

1. A rather poor job on Icom's part in making sure that accessory jacks
have sufficient RF decoupling. Very disappointing because this is well
documented, been done well in the past on most all rigs, and not rocket
science.

2. By the very nature of QRP and portable antennas and the like, often
there is a balanced to unbalanced antenna to line coupling issue. Which,
can cause the rig to be RF hot.

Alex, in my last post I discussed using ferrite beads to decouple
transmission line RF currents.

I also suggest that you look at an antenna book in the coupling line to
antenna sections. Here you will find many discussions about balanced and
unbalanced antennas and how to couple them to the transmission line. And
you should find a section about using the ferrite beads as a 1:1
balanced to unbalanced current balun.

Hi John, hi everyone,

sorry for the long silence. Business kept me "under water" and away from reading my e-mails. Yeah, it seems as if I got the keying problem under control. I improved the grounding by using a shorter cable with a larger diameter - to no avail, the rig kept keying on and on. Then I connected the exterior part of the key plug with the ground-connecting screw (as suggested by some of you) -and, suprise surprise, the wild-keying disappeared and never turned up ever since. This was about a week ago and I worked every morning a few qsos without any problems. The tuner works fine, too.

However, I have to admit that I trust my good old workhorse SG 2020 still more than the new IC 703, and preparing for a 2 weeks vacation in Italy, I might rather pack the 2020 than the IC 703. Haven't decided yet ...

But nevertheless, I would order the IC 703 again if I had to decide again. Hope this helps.

Thanks to all of you for the many good advises, let's hope the keying problem won't haunt us too often.

Regards

Alex, DL5OA

Hi Erwin,

in my opinion the receiver of the IC 703 is spectacular. If there's a problem with the IC 703, it's not the rx. In a few cases (including myself), people had problems with keying CW. You'll find details in the IC 703 group mails (stichwort "running key"). However, I believe the IC 703 is a great radio and I am having a lot of fun with it. Despite the initial problems, I would buy it again.

Hi Erwin and others,

Ermm: deaf is relative. But the RX is quite good - not as good as my K2, but
for a relatively low-budget radio it's quite good enough. The 703's RX is
far superior to the '817s - try both on a 40m dipole in the evening and
you'll see what I mean :-)

And whichever you choose there's outstanding freeware CAT software available
from HB9DRV.

Like Peter I have both rigs (Peter sold his FT-817). For shack use the 703
wins every time as long as 2m and 70cm is not important. For backpacking /

Hi Erwin,

I had a FT-817, bought an IC-703.. liked it so much I sold the FT-
817. For me it was a very easy decision to make..

If being very small, running off internal batteries (doesn't run for
long) having VHF and UHF are all important to you than get the FT-817.

If the above is not a major concern go for the IC-703.. IMO it is a
much better radio for most operators, works great and is easier to
use. The tuning knob and display are a lot bigger.. more usable size!
With the IC-703 you don't need to pay extra for a speech processor or
DSP add on most models (may be different in Europe?)The built in ATU
will match antennas that many other internal tuners can not. You get
a whole lot of radio for the price..

I say this having owned and operated both radios..

I also own an IC-746 and have never found any problems with the
receiver. I do find that some things work better on the IC-703.. The
DSP seems better and the ATU will tune my a much wider range than the
specs lead you to believe.. For example, my IC-746 will not tune one
antenna on 80 meters while the IC-703 has no problems tuning the same
antenna.

As you own an IC-746, another advantage is that the IC-746 will share
some of the accessories.. eg. the CI-V radio interface. If you go
with the FT-817 you will need a CI-V for the ICOM and a CAT for the
Yaesu..

To be fair, you should expect a lot of pro IC-703 replies in this
group. Now if you go to the FT-817 group, you will get a lot of
encouragement to buy a FT-817.. That's just the way it works.. Hi..

Hi John and the group,

I'm not knocking John's page as it is a collection of information he
has found and gathered together. Also I only gave it a quick read. My
only thought is that someone looking at the problems listed, without
comparing problem with the other rig may be scared away from the IC-
703.

Most of the problem listed for the IC-703 are new to me.. Maybe I
missed the discussion some were along the line. The CW keying problem
has been talked about and seems to be due poor grounding. It has
never happened to me. As to the other problems, they do not appear to
be very common. Normally those with problems look to a group like
this as a place to complain and seek help. I'm not sure now many
members we have in this group but I can say I have not heard many
complaining about the IC-703.

In the FT-817 group, there were a constant messages about blown
finals, to the point that it could get you worried.. It never
happened to me when I had one.. Also the tiny power cord and
connector, without any fuse got a great deal of discussion. I seem to
remember some talk about the finals and maybe even the FT-817 being
discontinued.

they didn't disappear in the low bands.

to ground the keyer.

I picked up my 703+ at Hamvention, no worries on this end. It loads up every antenna I've hooked up
to it. Got the 706MKIIG as well, and the 703 definitely has a hotter receiver. The radio is on at
least 5 days a week, and I TX on it at least 3 times a week. Maybe I got a good one, or maybe the
eHam reviews are full of subjectivity (as usual).

Hi Roger...

No problems and no complaints.. I love my IC-703..

I won't go over the reasons why I bought the IC-703 and sold my FT-
817, or all the things I like about the rig, you can read that in the
previous messages..

A couple of things to keep in mind, there will always be some
problems, no matter what you buy, it's a fact of life. Even
$50,000 cars have problems. You just have to hope you are not
the one with problems. Also, people with problems tend to be more
vocal about them, they seek out groups like this, eham etc to vent
their anger and complain when they feel unfairly treated.. Some
comments and reviews may not be fair and give a negative view of
a product when it is not deserved. Satisfied users are too busy
having fun and may bother with groups and telling people how happy
they are..

This group was started a years ago before the IC-703 was even
available in North America.. It is always good to read past
messages in a group.. You will find lots of comments and a
reasonably good over view of what users think about the IC-703..

Doesn't have a tuner, but real QSK, max of 20 watts, no filters
required because of the DSP, and built in computer interface. A bit
more money, but it is worth it. The 703 has some quality problems.
Some units seem to be o.k., but too many people are having problems

a 10 meter dipole. That built-in tuner is amazing!!! I haven't found
a situation where something I connect to it won't load.

Further to my question about reliability I have recieved this e-mail
from Peter DL2FI:

Sometimes I wonder, what Hams are presenting at eham.net reviews.

I think I have the first 703 coming to Europe because it was a rig
we got for a test review a month before one could buy it from the
dealers. In the mean, the German club magazin published their own
test review done by their own test specialists.

Result of both: a great receiver. In my own words, written in our
test review: The best I had on the work bench since I tested the K2.
Dynamic range, blocking, Intermodulation of Receiver ... All
excellent. In CQDL, the club magazin they said, the tx/RX relais is
the only bad thing. My personal view: I am doing CW only, but
because I use headphones I never had problems with this little reed
relais.

A well known (and fixed) problem is a "hanging" keyer if you do not
use the internal keying electronic. This was because the robot
has "forgotten" to solder 2 4,7nF caps to the keying line :-)

Compare a 703 with other modern rig by listening to an S5 CW signal
whilst there are strong CW signals in the neighbourhood, lets say 3
kHz away and you will see why I am saying, the 703 has a real good
receiver. (Yes, the K2 is better in CW)

Bought my IC703 at Dayton and thoroughly enjoyed it until the RF
output dropped to almost nil. Sent it back to the dealer (AES) and
am awaiting the verdict. I expect that if the dealer can't fix it
they will (as they indicated) fly it out to Icom on the west coast.

I realize that some reviewers may use eham and other product review
sites to bash and trash, but most don't. My review of the product
was an honest one. The IC703 has the potential to be an outstanding
rig for the serious QRPer. But it also has the potential to be a
disaster for us as well. The failure I experienced was IDENTICAL to
that experienced by another user. The driver transistor opened up on
his rig, and it appears that mine did the same. Are there others
about to experience the same thing? I'd guess there are (see the
complete correspondence at QPR-f). My second product review post on
eham was admittedly made in frustration, but that too is honest
commentary. Icom has a problem on its hands and seems, so far, to be
in deep denial. My fellow QRPers deserved to be warned, in my opinion.

When I get the radio back, I will report factually what exactly the
problem was.

Hi, folks.
Just found out about this group and thought I may as well join in.
Without going into a lot of technical detail, I'd like to say that
the Icom IC-703 is the 'most-fun-to-operate' rig I've owned in my
mere 38 years of hamming. More fun, even, than my beloved Meissner
Signal Shifter, model EX...one of which was my Novice(WN4BJC) rig
back in 1965/'66.

I bought my '703 used in July 2003 and it was working fine upon
delivery.
Being a used rig, I have, of course, no warranty protection.

After a few days of operating...mostly CW and RTTY...the output power
became intermittent, changing at will, anywhere from full output power
(as set by the max power function) to only ten milliWatts.

Long story short, the driver transistor, Q150...a Mitsubishi RD01MUS1
one-watt power MOSFET...finally went totally open. This still allowed
ten milliWatts of rf out because energy from the pre-driver, Q101,
passed through the gate-drain r-c circuit around Q150, providing just
enough drive to cause the push-pull finals...a pair of Mitsubishi
RD07MVS1 devices...to develop 10 mW output. I managed to work one
station, in Venezuela, from here in Pulaski County, Virginia on 20
meter PSK31, with the driver transistor removed from the rig and only

I ordered from Icom the IC-703 service manual, and subsequently a

I have e-mailed Peter to ask if he can share the IC703 measurements
with us here:

"Hi Peter,

People on the IC703 Yahoo group have asked if it is possible for you
to publish some of the measurement figures on the group? (Dynamic
range, blocking, Intermodulation results. It would be
interesting to see how they compared to QST review of the IC-703).

The group address is http://groups.yahoo.com/group/IC703/ and you
would be very welcome to join of course!

By the way, I think no-one is arguing that the IC703 receiver has a
very good but there do seem to be too many reports of transmitter
failures.

I have had my 703 for several weeks and love it.I got the 250hz cw
filter and it is as sharp as a straight razor. But, like some others,
I have had a problem with rf locking up the keyer. I emailed Icom and
got this reply..."move the rig farther from the antenna". N0 other
comment on the problem. Now I read of a simple way to alleviate the
problem with a short jumper from the common on the keyer plug to
ground. All I can say of the tech who responded to my sincere
question is: He came accross like an arrogant JACKASS. He made no
acknowledgment of this obviously common problem or offered any other
advice .Icom needs to send its techs to Ten Tec to learn what
customer service and public relations mean. I love this radio, but
can't say much for the arrogant jerk who answered my email
question....at least that is the way he certainly seemed with the
curt reply. Hope this was just an isolated incident with Icom
service.I can't wait to try the jumper wire solution.The 703 is more
fun to use than my almost new TS-570sg. The Kenwood is a better all
around cw rig, but the Icom could stand alone as the only rig in myh
shack. Ilive in Sarasota, FL. and it will be a great battery operated
rig for the storm season. Bill Anderson WB4TJH
| 414|414|2003-09-07 04:16:31|n4qa|IC-703 key jack/ key-line components, or, so says the service manua|
I too have experienced erratic internal keyer operation due,
apparently, to rf feedback. So far, I have experienced this only in
the mobile...a '93 Toyota light pickup with a Hustler mobile antenna
mounted on the rear bumper.
The only other antenna I use with the '703 is an end-fed wire, 250-ft
in length, nearest point of which is about 100-ft from the rig.
I'm using a Heathkit HFT-9B QRP tuner, mounted at the antenna's
feedpoint(top of a fencepost). 100-ft of cheap R/S 50-ohm coax
between tuner and '703. No keyer problems noted, any band, using the
end-fed wire. Ok using or not using the internal 'a/t' for a closer
match. But, I must emphasize that I tune the end-fed wire antenna AT
the antenna with the Heathkit QRP tuner and use the '703's 'tuner'
only as a 'transmatch' and only when necessary.

According to my copy of the IC-703 service manual...copyright 2003
Icom Inc...
there are no capacitors on the 'dotk' and 'dask'(Icom signal names
for the lines originating at the key jack) lines anywhere at or
between the key jack and IC5901, pin 73('dotk') and pin 72('dask').
IC5901 is the 100-pin M30620FCMGP computer chip on the 'Main
Unit'(Top board).
No caps shown on the 'Main Unit' schematic...none shown on the 'Main
Unit' PWB layout diagram.
There ARE, however, six surface-mount ferrite beads, shown on both
the schematic and the PWB layout diagram, present in these lines.
Specifically, devices EP6911 & EP6921 in series between key jack dash
and IC5901, pin 72;
Devices EP6912 & EP6922 in series between key jack dot and IC5901,
pin 73.
Plus, devices EP6923 & EP6924 in series between key jack common and
chassis ground. Chassis ground is also circuit ground.

I have NOT lifted the 'Main Unit' to see the actual components in my
IC-703. According to the layout diagram in the service manual, all
six of these ferrite beads are located on the bottom side of
the 'Main Unit' PWB.

In the mobile, I've been able to 'calm-down' the keyer with
appropriate grounding of the rig via its rear ground screw and the
vehicle body. But, I may look into the problem further...

Hello.

I've just experienced a weird situation.
I was happily calling CQ ( the radio had been on for some hours in RX
& TX) and suddenly there was no TX power, no ALC movement and no SWR
readout on the meters. I thought 'uh oh the mic' but it was keying
the radio on FM & SSB but with no power out, it didnt appear to be
TXing the radio at all. The only way i got it to come back was
to 'reboot' the radio by power cycling it.

Has anyone else has this occur? If so did it lead to anyting worse?

Best regards
Greg

Hmm its happened again, and this time i checked on a receiver there
is a tiny amount of output on the FM band, no signal indicated on the
meter but an awful tone is transmitted on the FM mode. This radio is
only 1 day old from the shop :((((

BTW, my IC-703 is serial number 1801416. It's the hf-only version.
It is my understanding, regarding the first two digits of the s/n:
18 for all hf-only '703s
15 for all hf + 6 meter '703s

It appears that the PWBs documented in my copy of the service manual
are of later revisions than those actually in my '703.

'Main Unit':
B5904G in the rig
B5904H in the service manual

'PA Unit':
B5903F in the rig
B5903G in the service manual

It is conceivable that capacitors on the key lines...or any number of
differences among PWBs of differing revision levels...may indeed
exist.

The plot thickens...

I took it back to the shop, where magically it worked again on their
bench. Even when i tested it the following day at home it still didnt
work, after a vigerous shake aswell. Conculsion from the shop's
bench: intermittant fault probably caused by a bad joint in the PA
stage. Solution: Well i didn't come away with the IC703, i paid a bit
more and got the radio I was really after in the first place:
IC706mkIIg. I still enjoyed my experience with the IC703 and It will
be a cracking radio if only Icom could weed out the bugs in it (and
also confirm) these issues.

Anyone using the AH4 with an IC-703?

I tried to use a SG-239 and found my IC-703 cuts back the power to a
level that is too low for the tuner to work. One thing I learned is
the hi SWR protection works.. hi..

The AH4 should work fine as ICOM recommends it for use with the IC-
703. I'm interested in other users comments before I decide to change
tuners..

| 425|424|2003-09-15 09:52:02|f6acc|Re: IC-703 and AH4 ??|
GA Ken,

I did not used the AH4 but I suppose that, as AT180,it needs at least
8watts fr tuning (see Instruction manual,page 89)
Most automatic antenna tuners need more than 5watts except those made
especially fr QRP.
Try with full power . Once You have tuned , You can go to lower power.
Long life to your IC703:I get 2 ,both died after about 10 hours!!!
I am waiting driver mosfet the keying problem having been fixed.

Hi Jean,

So far so good, no problems with my IC-703 (no 6m). It is only a
month old so still a few months warranty left.. If something fails, I
hope it is within that period.. hi..

FYI From what I read when HA-4 is in tune mode, the radio sees this 50
ohm load so is happy with a near 1:1 SWR, it can easily supply the
wattage needed to tune. The AH-4 actually only used around 350 mw for
tuning with the rest displaced in 50 ohm resistors. this being the
case the IC-703 should work OK.

with other tuners, such as the SG-239 I have now, the radio see what
ever load is in the path to the antenna through the tuner. If it is
too high the IC-703 cuts back the power below the level needed to
tune.

Not sure about the finals being the same on both versions of 703. I can say that I have had my 703+ on 24/7 for almost a month and worked all bands at full output with no problems. The tuner is excellent and the receiver is hotter then the 706G with a lot less noise "birdies". The DSP is the same or a bit better the 706G. Over-all my 703+ has been well behaved and works as it should.

Got my IC-703 back after its trip to the factory for repairs. The RF
output basically went away on it as I detailed in my other post. The
verdict from ICOM was pretty simple: The driver transistor died. It
was replaced, and the radio seems to be working ok now. How long this
magic will continue to prevail is anyone's guess. As if there was any
doubt before, there is now clearly a pattern to the 703 failures. A
sad thing for a new and very promising QRP rig.

My AH-4 arrived this afternoon. First impression was it sure is a lot
smaller then expected.. It looks bigger in pictures.. Yes I had the
measurements but I never really worried about the size..

The first project after unpacking is to open up the tuner. You have
to do this to connect the control and coax cables. This is nice, no
need for an excuse to look at the inner workings.. hi.. The control
cable comes ready assembled with a connector on one end and tinned
leads on the other that push into a quick connect connector. A good
quality of grey covered coax was supplied along with 2 - PL-259
connectors that have to be installed. It took a while to get the
connectors soldered on, hook up the connector as well as screwing and
unscrewing the 8 screws.. Next step to put it in service.

The set up here, I have the AH-4 mounted on the wall near the roof
where a short piece of 300 ohm TV twinlead enters the shack. the 300
ohm twinlead feeds an antenna cut for 80 meters. How does it work?
Really well and tunes up on all bands in a very short time. It even
loaded up on 160m though the SWR is around 2.5:1 and the power output
is cut back (is not rated to work 160m) The power consumption is very
low. I do not see any noticeable difference in current draw in
standby with the tuner plugged into the 703.

Now I'm a happy camper! This is the tuner to go with if you want to
tune various wire or whip antennas. The way it is designed the radio
always seeing a 50 ohm load when tuning, making is work well with low
power rigs, no problem with the SWR protection cutting back power
here!Other tuners don't offer this feature. Using the same antenna, I
have none of the problems I had encountered using and SG-239 tuner.

Hi Simon -
heh heh....bit of a jump from a 703 to a 7800....just joshing. Simon, I have been eyeing the 703 but get the impression power out adjustment is not simply a matter of twisting a dial....is that correct? Is it locked into 10 watts out only or can you control it down to milliwatts? Thanks for any input. I presume that Icom will take care of the only two negative issues I hear: failure to ground the key and some blown transistors. Cheers, Tim NZ7C

Hi Tim and group. My 703+ has been on 24/7 for over a month now with no problems found other then grounding the keyer plug on the back inside of the radio. Output is fully adjustable down into the mW range, right up to a full ten watts output. The receiver is better then the two 706G's I've owned. Menu is very similar to the 706G. Tuner works excellent, no problems tuning up my G5RV or other vertical multi-band HF antennas. I'm very happy with it so far and getting excellent audio reports with the stock microphone. What else can I say...

Hi Hans,

Have you read the past messages??

I almost worn out my keyboard saying nice things about my IC-703 (HF
only).. What more can I say without sounding like a broken record..
(now it did it.. dating myself.. a record is what we had before
cassettes and CD's.. hi..)

You will also be surprised how well 10 watts gets out.. even on the
low bands.. I regulary check into 80m SSB nets with no one noticing
that I am not runing my IC-746.. I've had comments like it doesn't
sound like a QRP rig.. It has really great TX audio and the
Compressor works well..

As mentioned previously, the AH-4 makes a great accessory for whips
and random wire antennas.. I wish the internal tuner worked as well..
hi.. What a shame as Icom could have done this.. The AH-4 pc board is
not very big and it is a 120w version..

OK, since you asked.... :-)

I bought an HF-only (version 18) 703 in early May, when the local
HRO store in Phoenix AZ finally got them. Used it from home and
also in the mountains of northern Arizona for ARRL Field Day. I
worked only SSB with it, but like others have said I had good
reports on my signals and audio. I sold it in late July, when I
bought an HF/6m (version 15) 703 from the same HRO store. The
HF-only 703 had no problems while I had it, I just wanted to get
the version with 6m, and I haven't heard a thing from the guy who
bought the old 703. So far, the HF/6m 703 has been as good as
the HF-only 703, no complaints from here.

I don't do much CW, so the key problems haven't been an issue, but
I plan on using it more from around the house - maybe even outside,
if the temps keep falling. In about a month I will take the 703
with me to Vancouver BC for a long weekend. I'll probably do
some CW from there, but there is a contest that weekend I will
probably try for a little while (CQ WW SSB).

Purchased my 703 (hf only) from Texas Towers in July. Didn't get to
roll it out till August. Don't know what I waited for. Operation and
features supurb. Normaly I'd be carrying a SG 2020 ADSP2, Z11 with
balun, and 44' twinlead fed dipole. Now less stuff. 703 and
Commercial Buddipole. Alright I don't have the frequency agility of
my SGC setup as the tuner in the 703 does not have the range as the
Z11 but, all I have to do is get the BP close and the tuner does the
rest. My next venture is a home made YOYO. Two camping clotheslines
(Walmart less than 2.00 each) packed with about 40' of #26 stranded
from the hamfest. "T" type center insulator fashioned from side of
laundry detergent bottle. Odd length of RG 58 (18') and some type 43
beads at the feed point. If I spent $10.00 it was alot. Pre marked
the lengths with a black Sharpie pen. Just support and pull out the
desired length and apply fire to the wire.

HI

I have used tow EH antenna as Mobil antenna and operated 357 qso´n this summer.

When I look through my log I can se that, there is 3 S-unit difference between receive and given rapport.

Reason for that is all received station was working 100 watts to 1KW and used Beam ore Quad.

I have only my EH-antennas and ICOM – 703 with 10 watts.

Even DX Europe to USA. (not bad)

I am satisfied with my EH antennas L+L from arno electtronica and KA4Q GeorgeÂ’s backpacker they are equal

Hallo,

my IC 703 works great. The receiver ist very very good, the tuner matches my G5RV on all bands...

Yesterday I recognized a little problem: I worked outside and directly under my antenna (G5RV). Only on 40m, unfortunately around 7,03 MHz (our qrp-frequency) there are some "ghost-signs" in cw: if I key the trx, sometimes a dit or a dah is added. I thought, that is caused by HF and I put some ferrit-cores over the key-line. But this doesn't solve the problem. Now I made a direct connection between the Ground of the key-jack and the ground-screw of the transceiver-back. It seems to work great.

Has anybody of this list the same problems? And how has he repaired it?

HI!

Everybody has that same problem!!.
The solution is simple, to connect the ground from the rig to the ground of
the keyer.
You can make it in an external way (such and like you have made), or to make
a small welding inside the rig.
I after proving with the ferrite chokes, decided to make this

Hallo David,

thank you very much for your answer. I had the same idea as you and I will make this little internal weldind...

I just tested, if it solves the problem really. I made a short open wire connection to the antenna and put the keyline between: with this optional connection there s no problem; without the transmitter doesn't stop sending.

When installing an INRAD filter, I recommend you isolate it from the

sporadic shortcut...

Except that, it works absolutely fine.

Hello Everyone,

I've been reading the posts here every since I got back from Dayton.
I'm impressed by the way most everyone conducts themselves here on
the list.

I'm glad to see some positive comments here as the reviews on e-
ham.net have been less than complimentary for the 703. I've liked
the concept of this little rig from the beginning and more so after
eye-balling it in person at Dayton. I've been waiting until winter
to take the plunge(the rat hole is in the process of being
replentished) before purchasing this little rig. I'm looking forward
to being part of the group for real and taking it portable when the
XYL and I travel.

There is a technical review of the IC703 by Peter Hart in this
month's RSGB RadCom together with a user review showing portable use
with whips and a Buddipole.

Before anyone asks, I will NOT copy the article as this is RSGB
copyright, but suggest you join the RSGB to see what it says
instead! You will find plenty else to enjoy too.

What I will say is the reviews were generally favorable but did
mention erratic keying problems on CW and an IM2 problem with 40m BC
interference getting through on 20m RX. Overall it was complementary.

The 703 works fine when I first power-up. Then the "Power"
and "SWR" indicators stop funcioning.
The ALC continues to work fine. Also when this happens the internal
Tuner stops functioning as well.

I keep an external SWR in the line to check on it. and that shows
that the power output is fine, but just the 703's meter shows no
power.

Has anyone else had this happen? And if so, what can I do to figure
it out?

A complete re-boot clears it up, but only temproarilyu.

At the request of another ham, I made several tests tuning with the

watts and give a minimum of 5 watts. It was interesting to find that
even at the lowest power setting on the IC-703 "L" which should be
1/10 of a watt, the AH-4 tuned up the same as it did using 10 watts.
Further proof of how well the it works with the IC-703 at all power

| 476|474|2003-10-05 05:22:28|Eric Sluder|Re: AM Broadcast listening|
I listen to SWB quite often with my 703+ and it sounds quite good
considering the small speaker. I listen in on 3.880 and 3.885 from
time-to-time as well and the Hams there sounds good as well. It does have
the down side that the sensitivity is preset (can't be adjusted like SSB
with the RF Gain control). The IF Shift feature doesn't work on AM either,
but that's not a big deal. You'll find that with a large antenna, it can be
overloaded on the heavily used SWB bands, so the attenuated will need to be
invoked (or use your external tuner as a preselector which helps a lot of
the times). I've even heard some 6 meter AM'ers on mine (was unable to work
them due to a poor antenna situation on my end) and they sounded good. Two
of the fellows were using the 706MKIIG's for their AM transcievers
(interestingly enough).

Hope this helps...

Hi all,

This is a copy of a posting to the Ham Radio Deluxe group - you have been
warned!

If you have a narrow filter fitted that you use with the 703's DATA mode,
you will find that switching it on from Ham Radio Deluxe or PSK31 Deluxe
results in your rig being switched to "normal" SSB mode. This means that
your microphone will be open in TX, and if you have the speech compressor
switched on, it will also be working. Switching the narrow filter from the
rig's front panel works as expected.

This behaviour is down to an anomaly in the 703's firmware: it's NOT the
software misbehaving, and we haven't been able to think up a workaround.

IC703 users are advised to remove their microphones and disable speech
compression when using any form of input to the rear DATA connector.
(When using CAT software, that is)

--- In IC703@yahoogroups.com, Frédéric Paché at: http://groups.yahoo.com/group/miraclewhip/

This group has about 350 members and you will find plenty of users
who will be willing to share their experiences of this antenna.

With a counterpoise or ground in the shack (in my case just a
waterpipe attached to the central heating) I have worked into LA on
40m with 5W SSB using the FT817 and into LU on SSB (11000kms+) on 10m
SSB. Also, all around Europe on 6m SSB. In all, I've worked 5
continents with the Miracle Whip indoors with just a central heating
ground - all on SSB. It is certainly FUN.

The antenna works better on the higher HF bands, DEFINITELY needs a
counterpoise or ground, and will always be several S points down on a
dipole up in the clear. On controlled tests on 20m by the HF Pack
group it measured 29dB down without a couterpoise on a 1/4 wave in
the clear and 10dB down when using a counterpoise. On 15 and 10m
results will be slightly better. So, if you can stand a few S points
drop you may have a small, easily tuned multi-band solution.

One thing to watch is noise pick-up. I use a small switch-mode PSU
and on some bands the Miracle Whip does pick up some noise from it as
it is only a few metres away.

Good luck and 73s

My new IC-703, HF only, serial number 1801436, arrived from AES yesterday.

Using a simple 1/4 wave 20 meter mono band ground plane vertical with
four radials.

Wow, what a receiver, nice audio, just sounds good!

Worked several 20M SSB stations. They all reported very nice received audio.

Than tried, for grins, to load the 20M vertical on 40M. Tuner matched it
up in just a second or so. There was a note on this group, or another,
about relay chatter. The first auto tune is a little surprising because
the rig does create quite a relay chatter during the short tuning period.

I was able to make a 40M SSB contact, received a complementary signal
report. Than tried 40 CW, using my CMOS4 keyer, worked perfect.

Only disappointment is that this is one of the HF only rigs marked
HF/50MHz on both the box and radio. I was not informed of this when
ordering over the phone. In looking through past posts, I see that N4QA
has 1801416, purchased used in July. With a difference of 20, they are
not moving many of these.

Found a nice feature, when using batteries, it does have a DVM on the
power input.

First night report, VERY impressed!

Hi all,

An anonymous poster asked:


I've had an FT-817 and I have an IC-703 to supplement my K2.

If you want 2m and 70cms, then you'll be better off with an '817. If you
want a reasonably good RX then you should choose the '703.

Whichever you decide on, there's excellent FREE CAT software available from
www.hb9drv.ch

If I had to choose again, I'd go for the '703 any day :-)

I have had my 703 for a couple of months now and continue to be
amazed at the receiver. I have the 250hz filter and work mostly 20
meter cw to a 75 meter dipole fed with 100 feet of 300 ohm radio
shack twinlead and a small 4:1 qrp balun in the shack, connected to a
couple of feet of coax to the rig. That allows me to use the internal
tuner on all bands. I have worked so many other qrp stations that it
is impossible to remember them all, but the one cw contact that
stands out was working VE7SL in British Columbia, in Canada. He was
running 100 milliwatts from a tuna tin special with a single 2n2222
transistor. Considering that I live in Sarasota, Florida, that is a
heck of a long way on 100 milliwatts. VE7SL has an interesting web
site, too, so check it out. His signal was about at 349 here and the
703's receiver really stood out. I also recently worked a kayak
mobile who was using an FT-817 on SSB 17 meters who was in the middle
of Beaver Lake on the White River in Northwestern Arkansas. I still
have to be careful of rf too near the rig, which will sometimes lock
up the keying circuit, but over all, the 703 is a superb radio and a
lot of fun to operate. Hope this makes up for all the negatives we
have read on this web site...so far so good for me...no problems with
the radio. I would buy it again.
| 494|487|2003-10-14 19:23:03|gzustway|Re: 703 vs. FT-817|
I want to get into qrp cw. But I only have money for 1 rig and the
newer multi modes are atractive and I want to get the most
flexability for my buck. I had an FT-100D but I just cannot live
with a radio that sounds like a 747 ready to take off every time I
key. My concerns are the 703 seems to be getting bad reviews (keyer
lockup and finals failing) The 817 reports weak audio but is suppose
to be the swiss army knife of ham radio. Everone seem all wrapped up
in what they can interface their 817 with I wonder how many contacts
people are making with them. Also I'm concerned that when the cycle
comes down off its peak an 817 won't cut it. Hard choices.


| 495|487|2003-10-14 19:35:55|John Oppenheimer|Re: 703 vs. FT-817|
It is a tough decision, they are different radios. With respect to the
703's quality, I just decided that Icom will fix any issues, if I have
any. And, everyone has been able to work around the key lockup problem
in some way. I have not had a key lockup.

I purchased the 703 mainly because I wanted the internal antenna tuner
and did not need VHF or UHF. I also decided that an external battery is
just fine because I can opt for different battery sizes.

I have had the 703 for just a week. I am really impressed with it's
performance. The receiver is exceptional. The auto null filter is a real
plus for operating SSB. Look at my 703 page at http://kn5l.net/ic703/ ,
where you will find some more information.

During the week I have made many contacts, both SSB and CW, and include
some DX such as DL, VK, and S5.

Hi all,

An anonymous poster asked:

The keyer lockup is EASY to cure - just add a connection between your key's
ground and the rig ground.

FT-817s had a spate of final failures - mine did too. And my 703 lost power
too - but I forgive it.


The difference between 5W and 10W is only 3dB - that's hardly noticeable.
But the 703's RX is better than the 817.

| 497|487|2003-10-15 07:01:50|Peter Bregman|Re: 703 vs. FT-817|
Last year I got the 817 along with the LDG tuner on EBAY. Thought it
was really cool. After all, here was this compact package that was
the most complete portable station imaginable. HF plus VHF. Walk,
talk etc. (It never worked out that way for me.)

Then I saw an ad for the IC 703. And thought, wow, what's this?
Here's a nice little compact rig with a tuner already built-in. Sure
it doesn't have all the bands of the 817 but damn! it's got a bail
and tuner.

Like so many I was torn. So I thought I'd buy it as well and conduct
a little test to see for myself which one would be better for ME.
(That's crucial since I don't know how you operate.) And whichever
lost would be returned to EBAY at a minimal loss.

To make things even, I built a new dipole antenna. A double unit that
was resonant on 20m and 40m. I figured, with a resonant new antenna,
the only discernable differences would be related to the rigs.

Here's what I concluded.

The main thing, if you're going to go into the QRP world or any part
of hamming, is you need a great receiver. Pure and simple. That's why
the Elecraft K2 is such a hit (aside from the pride of construction
aspect).

As the saying goes, if you can't hear 'em you can't work 'em. And
while the 817 rcvr is certainly capable, even with a filter on board,
it still suffered interference. And the 703 with it's DSP and
passband tuning for isolating both CW and SSB, simply blows it away.
Yes there are more bands covered on the 817, but the
clarity and sensitivity of the 703 and its ability to bring out
stations under adverse conditions that swamp the 817 makes it a
superior receiver.

What's more I found the sound quality of the built-in speaker of the
703 far surpassed that of the 817. So not only can you contact
another station, you can actually have a conversation without asking
the other station to constantly repeat themselves. Again this is
coupled with the superior ability to isolate weak and strong signals.

In another area, the small knobs and buttons on the 817, while
certainly adding to the compact nature of the rig, really got
wearisome really fast. The large tuning knob and well placed buttons
and controls on the 703 I felt were so much better. And the larger
LCD is so much easier to read. Both are small enough to set up
anywhere. I take it in the saddle bags of my motorcycle while camping.

When I needed to set up the 817, I constantly found myself looking
for a book or a rock or a stick. The built-in bail on the 703 is a
godsend.

I will give a nod to the 817 for having perhaps a more intuitive menu
system to navigate. But the 703, once you get used to it, is pretty
quick too. And for some critical functions that you need to get
input for immediately, it's often faster than the muli-press 817.

The 817, having the 2m and higher frequencies has an additional set
of memories and repeater functions that added to the 817's complexity.

Power is a comment that's always mentioned here. Well the 817 only
needs a little wall wart in the home or hotel and a lot of AA's in
the field. While the 817 is touted for its ability to have contained
batteries, changing them is a bitch. And you need a lot of them. I
think most folks would get the Gel Cell for either that can hold its
juice a lot better than a bunch of puny AA batteries, rechargeable or
otherwise. Here again the equation changes a little. The 703 with
it's really low power drain in rcv actually goes a lot farther than
the 817. Bested only by the Elecraft K1 and K2 from what I can tell.
That's pretty damned good. In the home a simple 3A p.s. from
RadioShack is all I needed.

Portability is, of course a major issue. I know when I got the 817 I
imagined all kinds of scenarios. But you know what? They never
happened. I liked the idea of walking and talking. (Although on VHF I
found myself wanting to have a little HT instead quite often.) It's
okay for repeaters, but not all that practical with HF stuff. You
really have to sit down to work SSB and certainly CW. So when going
portable, for me it was never going to be on foot. With the antennae
required, and all the other stuff, you certainly have to set up an
area to mark off as a station. At this point, either is small enough
for the job. And with VHF work and repeaters, I found my VX 150 still
had just as good coverage and quality. (In the above discussion,
while the 817's completeness is certainly sexy, I personally don't
mind having a great qrp hf rig and a great 2m ht to bring places.

As for the built-in autotuner, here there were big differences. The
LDG would tune a wire coathanger, no doubt. And is definitely a far
superior tuner. But unless you're one who does the wire in the tree
(or out the hotel balcony)thing, either is fine. Most of the time,
I've found people in the field tend to bring along a SuperAntenna, or
a Buddipole, or an Outbacker Joey or even the tuned dipole that I set
up. Not light but certainly portable. Antennas that don't require a
tuner. Although the tuner certainly maximizes the efficiency wherever
you are on the band. With these antennas mentioned either tuner is
fine. If you are a wire over the tree type, the LDG/817 combo may be
more appealing. You just have to get used to the fact that having
that tuner, will add another box strapped onto the 817 making it
nearly the same size as the 703. And then you have to deal with the
extra wires and the need a larger battery to get juice to the tuner
and stuff. A nice back pack from Mountain Ops does keep it all
neater, and admittedly, may work better for those who want just a
nice complete little package when on vacation.

For those who go on vacation or business trips and want something to
quickly set up with a simple wire, bands up the wazoo, the 817 may
perhaps be more appealing. You get beau coup ham bands, you need only
a wall wart for power, and you can use a wire tossed out the hotel
window or up a tree. On the other hand(and for a similar sized
suitcase package as the mountain ops thing), you can have great
receiver and an okay tuner. Power needs to be supplied from a compact
powersupply a little larger than a computer supply or a gel cell
battery. That's the decision.

Bottom line, you have to decide between an okay rcvr with a plethora
of bands with or without a great antenna tuner (LDG), or an
outstanding RCVR with an okay tuner.

Okay, I've gone on and on about all these other tings, what about
transmit?In transmit, I experienced no problems with either unit.
Certainly not of the kind so many have recounted on these boards.
Most could hear well with great reports given. I think I prefered the
4-5 extra watts that the 703 provided for additional insurance of
getting through while still preserving the minimalist power
requirements ethic of qrp. Again the xmtr with the better rcvr will
always be a winner in my book.

Of course, the 703 does not have those extra bands the
817 has. And the concept of the all in one rig is quite tantalizing.
But that is why I have a Yaesu VX 150. I seldom use 430 since most
users on my local repeater seems to prefer 2m. The 430 repeater,
while certainly available, seems to be saved for those 'special'
occaisions. But I have to admit, 817 seemed to hit the local repeater
better than the equally powerful VX 150. I suppose I could eventually
get a nice compact Dual Band huh?

Well those were my thoughts. The 817 went back to EBAY. The 703 is on
my nightstand.

Hope this helps folks with their decision.

Peter,

Thanks for the interesting comparison between the 2 rigs - a bit
long, but worth the read!

I understand the point about the FT817 and /P operation: it is rarely
possible to work /PM without trailing a counterpoise and having a
devil of a problem trying to hold things, take the log, AND speak!

Sounds like the IC703 is a good solid QRP all-rounder ...just as long
as they've now managed to crack the unreliable TX and the keyer
ground issue (the latter sounded a trivial one).

Whether I take the plunge and buy is still not decided. For now, the
FT817 must continue to be the station mainstay but Christmas is
coming and if I decorate the kitchen for the XYL ....

Glad you enjoyed the post. Sorry about my going on and on and on so
much. I'm kinda new to this posting stuff. And felt an answer
to your question required more than a line or two answer, but more
depth to give you perspective. I'll be careful in the future.
(Like..now?)

There was, however, one more item. An observation I find very
useful. It's a little test I call the EBAY indicator. Basically, you
go to EBAY , type in FT 817 or IC 703 hit search and see what's
available.

Now while the 817 has certainly been out a lot longer than the 703,
and thus more units around, it doesn't mean there aren't a lot of
folks who wouldn't have a 703 for sale.

In my forays on EBAY, at any given time, there were almost always 4-6
817's (and 817 related accessories) for sale. Yet despite the
grousing about the 703 either here and particularly on eham.net, the
703 has been rarely available. Like an Elecraft unit.

Interesting no?

Cheers and 73.

Peter,

Thanks for an interesting analysis of the two rigs. I will concede
that it seems like there has been a lot of TX failures in the 703
but I still am going to purchase one closer to Christmas. It's my
hope by then there will be some good buying incentives and by then I
will have my stash replentished.

IC703, NIB, LC-156 backpack, SP-10 speaker. Never used; I didn't
get the chance to even assemble my station before I lost my job, so
this has to go. Radio is new in the box, I only took the plastic
shield off the display. It was purchased about a month ago at HRO
here in Phoenix, I have the Icom back pack and an SP-10 speaker (new
also) to go with it. I really need to sell this soon to pay bills,
so I am offering it at a very good price. $450 shipped to lower
48. Contact Ted KD7YIF (x-N7ISM) at azlectric"at"cox.net

I also have an Astron 12A power supply and an MFJ 901B tuner for
sale, that would be good companions to his fine radio. Thanks.

The American Radio Relay League just published an amazingly positive
review of the 703 Plus in the November Issue of QST. The article is
also available at their website in downloadable PDF format. The
review raves about the rcvr sensitivity, qsk (he claimed it
approached legendary Ten-Tec capability), dsp, noise blanker, low
power drain and a lot more.

Enjoy.

| 506|505|2003-10-17 15:17:32|Beischel|Re: ARRL Review of 703 Plus|
Most every review in QST is positive in one way or another. To say
that the 703 approaches TenTec rigs as far as QSK is a little too
positive. My understanding is that the 703 uses a mechanical relay
instead of solid state switching. That is not "approaching" QSK in my
opinion. Second, other reviews of the 703 showed very poor keying
characteristics. Apparently those have been cleaned up, especially
the spike, so I guess you have to be careful as to which serial number
you get - anyone have any insight on when the keying was improved?

The reviewer also implied that the legendary QSK was only on old
TenTec radios. I can tell you the legendary QSK is still there on two
of TenTec's latest models, both of which I have, the Jupiter and the
Argonaut V.

It is nice to see Icom fixing these problems with the CW
characteristics. But the waveform on the TenTecs is still far better
although you might not notice it on the air. Now that Icom has
cleaned up the radio, I may consider it again and purchase it at
Dayton when the price should be more reasonable.

Hello All,
I just noticed Ham Radio Outlet has lowered the price of the FT-817 to
$559.
Maybe Icom will now follow and lower the Price of the 703. 73, Keith
| 508|507|2003-10-18 12:28:06|Dimitri Aguero|Re: ft-817|
I don't think so. This is just a hint that a new Yaesu transceiver will
replace the 817 soon.
Since the IC-703 is more modern and has better performance, there is no
reason to lower its price.

First, let me say that I'm enjoying my IC-703(hf only) very much.
I've made many contacts on most bands(including 60 meters USB) and
all its modes except AM & FM (only because I haven't tried AM or FM
as yet).

The IC-703 has been the primary rig in my shack since 14 July 2003.
Only serious problem I've had to date is a failed driver transistor,
Q150, a Mitsubishi RD01MUS1 MOSFET. Icom responded quickly to email
order for two replacement devices(one as a spare). Cost, including
shipping, about 8 bucks each. Of course, earlier, I purchased the
service manual which cost $56 including shipping. Since I had bought
the rig used(no warranty), I replaced the surface-mount driver myself.

I was somewhat surprised to see the review of the 'IC-703 Plus' in
the November 2003 issue of QST, having read the review of the 'IC-
703' in the July 2003 issue of QST.

The November review seems to have been written to highlight the 6
meter specs and that's well and good for 6-meter enthusiasts.

However, I must take issue with statements made which attempted to
persuade readers to believe that any current flavor of IC-703 has
anything even in the same league with Ten-Tec's 'legendary QSK'
characteristics.

The keying waveform of 'Figure 2' on page 78,Nov 2003 QST tells me
all I need to know about the transmit side of the '703's QSK. I am
happy, however, that Icom seems to have successfullly dealt with
the 'leading edge spike' issue.

Receiver recovery in full 'QSK' is so-so in my opinion.
Then again, I don't operate the '703 in full 'QSK' because
transmissions sound so horrible in any properly adjusted separate
receiver. Therefore, I operate in semi QSK CW where the '703 sounds
only ok in a separate receiver. But, don't try to break me, except
between words...

The '703's QSK is not even as good as that of my Kenwood TS-440S from
1986.
And, it falls waaaaaay behind that of my Ten-Tec Century/21 from 1980!
Yes, I know the C/21 had issues of its own :)

Hi all,

The good news for the computer-literate among us is that Simon
HB9DRV Brown
and I, aided and abetted by Henk Pit PD5DP, have now finished beta
testing
on Ham Radio Deluxe and release v1.0 is available as of now from:

http://sysgem.decus.ch/hb9drv/HamRadioDeluxeVersion1b175.exe

Rigs supported (at the moment) are:

Ten-Tec Argonaut 516, FT-100,FT-1000MP, FT-1000MP, FT-817, FT-847,
FT-857,
FT-897, IC-703
IC-706, IC-706MkII, IC-706MkIIG, IC-718, IC-735, IC-7400, IC-746, IC-
746Pro,
IC-756,
IC-756Pro, IC-756ProII, IC-775DSP, IC-910H, Elecraft K2, TS-2000, TS-
450S,
TS-570,
TS-580, TS-690S, TS-850, TS-870, TS-950, and there is NO truth in
the rumour
that Oner support is on the way.

You will find more info about this software on Simon's site
http://www.hb9drv.ch

The Ham Radio Deluxe suite of programs contains the following
components:

Ham Radio Deluxe - a CAT control program for your radio
PSK31 Deluxe - a sophisticated PSK31 program which includes
SuperBrowser.
SuperBrowser allows you to monitor up to 40 (!) QSOs at a time - the
main
restriction being the available processor's speed.
Mapper - an amateur radio mapping program which can not only be used
for
making your own maps, but which can capture and display Maidenhead
Locator
info from the PSK31 Deluxe screen.

Ham Radio Deluxe also supports speech announcements and alarms, but
you will
have to have Microsoft's TTS files installed on your computer. You
will need
to visit the Microsoft website to download and install a total of
about 8MB
(in two files) for this option if the files are not already
installed. The
URLs are:

http://www.microsoft.com/reader/downloads/pc.asp for the Microsoft
Reader

and

http://www.microsoft.com/reader/downloads/tts.asp for the Text-to-
speech
module

We advise the use of WinXP or Win2000, but many of our beta-testers
are
using Win98 or Win98se, and there's one poor benighted soul using
Win95 (NOT
recommended!)

Anyone wanting to use this software is invited to join the Ham Radio
Deluxe
discussion group at http://groups.yahoo.com/group/ham-radio-deluxe/
where
you will find a friendly and helpful bunch of people to help you
with any
problems. The group is moderated, and querulants and other sad
individuals
are kept in check - only happy smiling faces are permitted here,
y'know ;-)

| 511|511|2003-10-20 04:02:54|wb4tjh|703 QSK?...yeah, right...|
I enjoy my IC-703 very much and for the most part am very satisfied
with it. But in reference to the QST article praising the "qsk" of
the rig and comparing it to Ten-Tec's full break-in keying, that is a
ludicrous statement. The Ten-Tec solid state switching IS TRUE
full break-in while the Icom, good as it is, is MECHANICAL RELAY
SWITCHING, not even in the same league as the TEN-TEC. I also found
the article a bit silly in lavishly praising the 6 meter part of the
rig; as most hams know, six meters is often too sporadic to even
worry about.I have six meter capability with my Kenwood TS-570SG, but
can count on two hands the number of times I have caught it open in
the last couple of years. 99.9% of QRP operation is on HF, so 6
meters is just a novelty on the 703, and I would not spend the extra
90 bucks to have it on my rig. All you hams that pursue 6 meters on a
serious basis, please note that I am not knocking it or any other ham
band...you know how difficult and challenging it can be. I prefer the
dependable HF qrp operation. It is more fun to talk to someone,
rather than spend all my time listening to white noise on an empty
band.
| 512|487|2003-10-20 17:40:53|John Oppenheimer|QSK, reports & reviews|
First let me start with a positive. I am really enjoying my new IC-703!
If you like the feature suite, than don't let any of the negative
comments bother you too much.

I guess that the major unliked Icom design issue is the use of a relay
for the antenna switchover, which causes relay chatter during full QSK
mode. So, the IC-703 comes with all of the issues that come with an
antenna change over relay.

I have done an unscientific test of monitoring my 703 output at 30 WPM
in full QSK on another receiver using my memory keyer.It sounded just
fine to me and I have no problem having others copy my full QSK signals.
If only I could operate at 30 WPM ;-), I'm a 15 - 20 WPM guy myself.

It is my guess that differences in the ARRL 60 WPM QSK measurement test
will most likely be variances in the mechanical differences between relays.

I am somewhat surprised by some of the "glad Icom fixed that problem"
comments. The earliest reported serial number that I know of is from
N4QA with serial number 1801416 sometime around July. My new 703 is only
20 unites newer, purchased in October from AES. I received one of the HF
only marked with 50 MHz. One of the things that I did was to inquire
Icom about a swap with a newer unit, and asked if there would be any
electrical differences. Mike Hilton from Icom reported that the only
difference would be the marking and the quote from him is:

"No, there are no differences between the radios, just the front cover
markings showing HF/6 meters versus HF only."

There was a report about the "well known missing capacitors" in the
keying jack circuit. I have not seen any collaboration about that report.

Oh, did I mention how much fun the 703 is ;-)

I am waiting for my first IC-703 two way QSO.

Hi,
I do wish that designers of the Ham Radio Deluxe would also think of
the Mac and its Unix OS X operating system that also comes with X11.

There is a large group of people that look for ham Mac OS X software
(although there is some in http://sourceforge.net) but very few
available.

Please consider the Mac OS X platform. It is much better than
Windows, by F A R.......and developing for OS X and X11, means
developing for Linux as well.

| 520|516|2003-10-22 16:59:25|Simon Brown|Re: Why do people forget the Mac?|
Hi Peter,

For me it's a question of commercial interest and critical mass. All
companies who buy my commercial software use NT / W2K / XP so this is a
platform I know very well (some may disagree), I also have a fine
infrastructure here.

To create HRD I use about 40k euro worth of hardware and 10k euro of
development software. I estimate it would have cost 100k euro by now had I
been charging my time at a reasonable commercial rate.

So even if the Mac is the very best computer of all time I have to be
realistic. The effort to write an X / Motif-based application would be
considerable, the market is not awash with good Macs for 200 euro each
whereas a good PC can be bought for this price - a friend just picked up a
900MHz box for around this price range.

So concentrating on the Mac or Linux would exclude at least 90% of Hams, I
have users in 3rd-world countries using donated PCs and free Ham software.

Bite the bullet - XP is very good indeed, hardware dirt cheap and there's
lots of software available for Windows. Instead of spending 200 euro on poor
over-priced Ham software use the free stuff and spend the money on a PC.

Simon,
Good and to the point. If people would look at the origins of each platform, the Apple (whose loins spawned the Mac) inventors wanted the whole enchlada. Hardware and software. The only non Apple was made by HP (the Black Apple) but with all Apple supplied hardware. The Apple Bios was impossible to reverse engineer. In contrast PC's were hacked by every chip manufacturer in the Pacific. Prices fell and there was a PC almost in every house. If I were a software developer I would put my efforts into where most of my platform population is. The Mac maybe a good machine but people still by a PC and there will always be more PC's than a Mac hence more PC software.

1) - PC are cheap.. just bought a 400MHz PC with 128 megs of RAM, 3
gig HD, CDrom etc for $79 Canadian.

2) - Hams are cheap whether by nature or due to the need to stretch
their money as far as possible.. we love flea markets and bargains.

3) - PC Software is readily available.. cheap or free.. I couldn't
buy an apple program in a local store even if my life depended on
it..

4) - Apple computers are expensive and not readily available not even
sure where I could find an apple dealer, the local one went out of
business years ago, couldn't compete with the PC dealers..

Even our schools, long time users of Apples, are changing to PC
clones and Sun terminals with Linux...

It really comes down to Dollars and Cents.. Many of us either can't
afford and/or justify the extra cost of buying an Apple and software
for it..

Speaking of the IC-703 (we should be .. hi..) Most of us would rather
put that money saved by not buying an apple into a new rig.. Like the
IC-703 I bought a few months ago.. The IC-703 is working fine... sure

Hi all,

It was written:

Oh dear: just don't try it with a Yaesu rig. Kenwood and Icom seem to have
their act together - the 703 is quite good - but Yaesu take a perverse
delight in making every rig different. The FT-100 (the worst rig I have ever
had my hands on) has a manual full of inaccuracies, misprints and downright
lies that made me lose all faith in Yaesu. Similarly, Simon was most
definitely NOT impressed with the FT1000MP CAT stuff - the rig's OK, but the
CAT documentation and implementation - OH DEAR.

But Yaesu owners take heart: the 703 isn't perfect when it comes to CAT.
Good, certainly - but it falls short of excellent.

Thanks for all the comments. But think about the fact that I switched
from the DOS/Windows environment after 25 years (when it was CP/M
1.1) and that an eMac now costs $799 (which is less than 677Euros)
for a 1GHz G3 system, 128MB RAM, ethernet, modem, and color screen,
et al, which is much cheaper than most PCs sold these days. Think of
the software you get for free (look at what you get with Mac OS X)
and you realize what used to be expensive is no more.

Much like the ham world which changes and advances (although there
will be those who say it is moving backwards...), so does the world
of computers. And Apple, now, is an example of high performance at
very real prices.

Of course I have a PC (Thinkpad) but I just want to use one system
for the job. It would be great to have my iBook, my 703 and a dipole
to do ham radio while on a busines trip!

Hi Bill,

The AH-4 works great for me and doesn't seem to be too fussy what you
throw at it for antenna. I am currently feeding a flat top with
drooping ends, cut foe near 80 meters... (supported in the middle but
not an inverted "V") using 300 ohm TV twin lead. This arrangement has
no problem tuning on any band from 160 to 6 meters.

While rebuilding this antennal earlier in the month, I ran out of
dail light without finishing. I had cut off the 300 ohm feedline and
dropped it on the metal roof of my mobile home.. The length connected
to the tuner was just a bit over 25 feet. I disconnected the lead
connected to the ground and connectedf a wire to ground. I was
surprised to find that I had no problem tuning up from 160 to 6
meters, even on this short antenna. I never tried to make a contact
on 160 but was able to check in to a couple of local 80 meter nets.

I've been thinking hard about wether I should buy an

get the IC-703 and I'd like to get cw/rtty filters for
it as well. I'll be using it with pactor, and other
modes, from my boat and I need a filter thats active
in rtty mode. By looking at the brochure it seems that
only the 500 Hz filter is active in rtty, is it really
so ? I'd like to use the 250 Hz filter for both cw and
pactor (1), is that possible ?

I picked a '703 up a week ago and must say that I'm impressed too. It
took about 10 minutes to confirm the RF-in-keyer problem, but it only
took a couple extra minutes to ground the key jack while the top was
off to make the 60m mod and install the CW filter. As a '706 user the
time needed to get up to speed was nil. It's a bit of a bummer to
need to worry about fixing the keyer, but, on the other hand, it was a
very simple fix...and the antenna tuner works much better than
advertised. All in all, well done.

RF seems to get into the keying circuit, causing a runaway keyer
situation (extra dots/dashes added and/or the keyer just keeps sending
and sending and....). I've heard rumors that this has been fixed in
the latest units. Try yours using the internal keyer. If there's no
problem then you're done. If there is a problem, just remove the top
cover and ground the key jack ground to the chassis. An example is
provided in message 464 from about a month ago, and there is some
discussion in other messages from that timeframe. (The grounding
jumper is behind the two gray cables in the upper left corner of
the photo included in message 464.) It worked for me; however, the
usual disclaimers regarding proceeding at your own risk apply.

The most probable source of the RF current is the transmission line
shield being part of the antenna. I fixed my key lockup by placing
Ferrite Split Beads over the coax. May want to try it if you want a "no
rig modification" solution. More information on my IC-703 page at

Which end of the coax did you put the beads please? At the antenna

need to ask, even if it's obvious to everyone else.

Because, all I wanted to do was to choke off the RF current getting to
the rig, I placed the beads at the easiest place to put them, on the
short piece of RG-58 between the rig and the long run of RG-8 to the
antenna.

Yes, it can all be confusing. If the beads are used to match a balanced
resonant antenna to unbalanced coax, than the beads should be placed at
the antenna feed point. Having them at the antenna feed point will
isolate the feed line from the antenna therefore, not disturbing the
radiation pattern of the antenna design. If the coax becomes part of the
antenna, RF current is present on the shield, than the radiation pattern
of the complex antenna (antenna + feedline) may not be optimal.

The Ferrite Split Beads used in this way are also called a "1:1 Current
Balun."

Palomar sells the beads as a kit, see

cause no problems as long as you have the radio well grounded and a
reasonable match on the antenna. I wouldn't pay to much attention to

I operate about two hours an evening, four days a week, at 10W, on one

Hi Ryan,

It depends a lot on just how portable you want to be. I don't plan
any situations where I will have to carry my equipment too far from
the car. With that in mind, I went for one of those portable car
boosters with a 15ah 12v battery. Light enough to carry a short way..

There are lots of these portable car boosters being sold with various
battery sizes smaller and larger then the one I bought. Price wise,
in my area, I found this was the cheapest way to buy a battery, (look
for one on sale) complete with the charger in a nice package with a
carrying handle. In a pinch I may use it to get the car started..
hi..

My model also has a built in lite that came in handy during a big
storm during the summer. We lost the power and were in the dark..
After 4 hours there was not much change in the battery condition..
No, I never got around to operating that evening... with the wind
gusting over 100 mph we were more concerned about not blowing away..
One tower in the area was twisted and folded over. Trees were down
every where.. I came out lucky, only lost a TV antenna that was no
longer being used and left with trees leaning over about 30 degrees..

I haven't given the battery a good try out but expect I should get a
few hours of operation, even at 10 watts.

Last summer, I took my VHF handy when camping, but felt that what was
actually wanted was a portable HF rig. This would have to be frugal on the
batteries, as it may be necessary to recharge them from the car, or use the
car battery directly at the risk of flattening it. A long wire would be the
easiest antenna to get up, but would need a balun & probably an external
tuner. I had been considering an FT-817 plus tuner, but wonder whether a
careful choice of wire length & a simple fixed loading network would get the
SWR within the capabilities of the IC-703 tuner for (say) 40 and 20m. A
fixed loading network on the end of a few yards of coax might avoid the RF
breakthrough into the keyer. Obviously moving the tuning network away from
the tranceiver makes a manual adjustable tuner unattractive & while an
autotuner is possible, it doesn't fit in with the idea of keeping things
simple. Any thoughts anyone? If not, are there any recommedations for a
lightweight tuner.

The driver failures that a number of folks have had is dissappointing and
making me unsure whether to get this radio, but the spec is rather enticing.
Could be a manufacturing or a design fault. Has anyone had there rig fail

After reading back my post, it didn't make sense as i'd mentioned balun in
conjunction with a long wire. Whoops. The balun would go with a 40m wire
dipole, which is also a possible antenna solution.
| 562|561|2003-11-07 14:27:21|John Oppenheimer|Re: Thinking about getting an IC-703|
I too worried about the reported transmitter section failures, but then
just decided that if it happens, Icom will fix it.

The IC-703 internal tuner has been much better at matching semi random
antennas than I thought it would. I am using a mono-band 20 meter ground
plane vertical and the 703 will match it to all bands from 80 to 10 meters.

Another antenna to consider was in CQ magazine a few months ago. It
consisted of a quarter wavelength of wire at the end of a piece of coax
and than placing Ferrite Beads (Current Balun) over the coax a quarter
wavelength from the antenna end. Basically making a simple dipole with
the coax shield being one section of the antenna. With some
experimenting, you may find that you can construct a 20 or 40 meter
antenna and will be able to tune it to other bands using the internal
tuner. Or, carry several lengths of wire and mark the coax for the
different locations to place the balun.

| 564|564|2003-11-08 00:13:09|Morris Jones|Re: Digest Number 158|
Alan,

The tuner does OK if the wire is close to the correct length. I use a 20'
fishing pole as a vertical. It tunes 20 to 40 M by changing the wire with
quick disconnects and one coil. I fixed my keyer by the simple ground wire
attachment found in the digest. Can't say about driver failures as mine is
working fine. I also have an 817, and like the receiver in the 703 much
better even though the rig is larger. The Z11 tuner has a broader range of
tuning than the tuner in the 703, (The one I have at least) But with a
significantly mismatched antenna, I don't get good results even if the SWR
at the rig is 1:1. If you trick out an 817, it will cost about $300 more
than the 703. (DSP, internal battery upgrade, charger, Speech Compressor,
etc.) I use a 7.5AH SLA (Very cheap), and get an afternoon of outdoor use on
it.

Hope this helps,

As some of you know, I've just purchased an IC-703 to use at QRP picnics and the like. Now, the search is on for a way to power it for a morning or afternoon in the field. So far, I've come across two car jumper packs that look like they'll do the job, though neither link has an amp-hour rating. My Dad has a compressor pack that he feels will give me enough juice for about two hours. Any comments or suggestions?

The units I'm looking at are at:

FYI: Tested the radio in the shack using main power and dipole antennas with SWR's between 1.5 and 3:1. Worked ZK1 on 10 CW, HR and YV on 15 CW, and W5B in Denton TX on 10 Mtr phone, all running about 12 Watts out. TO0O on Martinique heard me on 20 CW, but busted my call. :)

Joel,

Not hard at all, although it's a hardware- rather than software-based
procedure. I think there's a description on both the mods.dk and the
HFpack Yahoo group sites. It's very simple (remove one component),
and much, much easier than installing the optional CW or SSB filter.
I was able to make both the 60m and CW key grounding mods in about 10
minutes, and that involved nervously checking everything several times
before applying heat.

Having said that, be careful and the usual disclaimer about proceeding
at your own risk applies.

To The Group:
Is there any way to replace the antenna tuner in the Ic-703 for a LDG-
11 Tuner? Would the exchange fit and how would you inter connect them?

--- In IC703@yahoogroups.com, "gary jamerson" them?
Gary, the answer is NO. The internal tuner is an intregal part of the
IC-703 circuit board. You can however add an external tuner by-
passing the internal tuner. Stay away from the SGC series of tuners,
they do not fuction as the power of the 703 is cut back drastically
with these tuners because they do not exhibit a 50 ohm input
impedance like ICOM's AH-4 tuner.

I have an SG-237 and know first hand. Other Ham's have also reported
problems with the SGC tuners. I since have switched to ICOM's AH-4
and it works flawlessly, highly recommend this tuner.

--- In IC703@yahoogroups.com, "dietmarfichter" I also have an SG-237 to an inverted L at my QTH, which seems to
like a good 10W from my IC-746 to get it to tune up. When tuned the
IC-746 reports 1:1 SWR, but switching over to the IC-703 reports
about 1.3 SWR. Both internal tuners were supposedly off.

On bands where the initial SWR is high, the IC-703 folds back its
power output such as to be insufficient to drive the external
autotuner. Perhaps the AH-4 can tune with a lower level of RF power.

Hello! Dietmar,

Thanks for the information concerning the antenna tuner.
I would like your opinion on which transceiver do you like best. The Yeasu
Ft-817 or the Icom-703 + 6 meters. I would think that once you add the LDG Z-11
antenna tuner to the Ft-817, then both radios would weigh close to same weight.
I might sale or trade my Icom-706mkllg for one of the above radios. Then with
better sunspot cycles not happening tell 2006 maybe I should just keep it.
They might have an Icom-706MllG or an update on the Ft-817 in the next two years.
You always want to get the best deal for the money. You don't want to kick
your self for making another bad decision like getting rid of the Ft-817 and
then regret it. Thats what happen to me 3 months ago.
Thanks for your help on the tuner. Take care and have a great week.

Hi John,

I use the IC 156 backpack with my IC 703 and I feel it is a bit too small (i.e. too short) for the IC 703, in particular if you wish to pack a lead gel battery which lasts some time. The key jack and the other connecting parts at the rear end of the IC 703 get squeezed. I found that the IC 156 is perfect for my SG 2020 (which is shorter than the IC 703) - but that's not what I bought it for.

If I should find a pouch which is as simple and well-designed as the IC 156, but a bit larger (and maybe a bit cheaper, hi), I guess I will buy it.

73 de Alex, DL5oa

John Pfeifer <yahoo@... Hello

Is anyone out there using the Icom IC-156 backpack with their 703?
If so, I'm curious what you think of it.

| 592|592|2003-11-18 02:00:43|Alan Waddington|First attempt at portable operation with IC-703|
This lunchtime I attempted to operate portable from the office car park.
The antenna was an ATX driveabout (bottom coil loading with 43" whip above
the coil) fixed to a 2 x 4 ft sheet of steel, which I backed with carpet.
The whole ensemble was put on the car roof & a ground wire connected to the
car. Using a MFJ antenna analyser, it was possible to tune this from below
3.5MHz to about 3.65MHz. Supposedly it should be possible to tune up to
3.8MHz without using any coil taps. However I believe the efficiency (or
otherwise probably in this case) of the ground plane affects the resonant
length. (Time to do some reading).

Incidentally, with an excessively shortened vertical, the useable <1:2 SWR
bandwidth was only about 30kHz, so an antenna analyser is a must for a quick
set up. Otherwise, the increase in background noise as the SWR tends
towards 1:1 gives a useful clue to resonance.

Signals from local amateurs were coming in 5&9, so feeling hopeful, I
depressed the key, only to get the keyer lock up. Having read earlier posts
on this subject, a hefty ferrite core was already gracing the key leads, but
proved insufficient. I am now trying the grounding modification after
inspecting the schematic at mods.dk to convince myself this wasn't going to
cause more problems. Better luck next time hopefully.

- went down to the local Candy store... big mistake... i always end up
a bit poorer everytime i step foot in the door... must resist... must
resist...

- but i found a brand-new return unit for $400+change (might i venture
a guess that the previous owner may have been a frustrated CW op, as
the unit was set to off-default states, such as full break-in and CW
bands?)...

- i've been an FT-817 user for the past eight months (great little
rig), but was surprised how quickly i was able to navigate the 703's
menus and settings... perhaps having had experience with the tc90a and
vx5r HTs has helped?

- anyway, i clamped the base of my MP-1 on a rail on back deck,
attached the radials (yep, i know, there are only 4 included with the
MP-1), and screwed in the 17M hamstick (from the Lakeview folks; about
$6 more than ATOC's or MFJ's)...

- i like 17M and have a lot of fun there... nice refuge when contests
are running and for more relaxed QSOs... i was quite surprised at how
well the hamstick worked on 17M... pretty resonant across the phone
portion...

- but here's the bonus: i also found that the 703 easily loaded across
the phone portion of 20M as well with the 17M hamstick!

- i know the rig's internal tuner doesn't have the range of other
transmatching devices, but i'm pretty happy...

- it's supposed to be one of those few remaining summer-like days here
tomorrow, so i'm going to do a mini-Field Day... load up a little
thermos of coffee, grab a hoagie (AKA grinder or sub), throw the rig
in my mobile mortgage, and head out to a local park...

- i've been itching to try a new SD-20 crappie-pole mast with a wire
dipole based on the venerable Mr. Cebik's comments in his article
"Suppose I Could Have Only One Wire Antenna..." at:

http://www.cebik.com/aledz.html

- i'll give the hamstick a workout, too... if i feel motivated (i'm
such a lazy bum lately), i'll post my results... (the SD-20 is only
going to get the dipole's apex up to 20 feet, and the antenna will be
in inverted-V configuration)...

- anyway, just thought i'd let you folks know about the loading of the
17M hamstick for two bands (and no, i didn't try across the CW
portions, 'cause i'm an idiot and still working on post-5WPM code
speed)...

Hello Everyone,

Well today I was visiting my daughter in the west burbs of Chicago.
So I says to myself, "Self, why don't you make a trip up to Milwaukee
and visit AES while the XYL and daughter are out shopping?". Well as
you may have guessed by now Self walked out of AES with a new 703.
The price was $589 with the coupons. I could have saved a bit by
ordering on-line and saved the Wisconsin sales tax but there's
something to be said about being able to take it with you. I'll
report later when I get back to south central Iowa and get it fired
up. Looking forward to being part of the group.

- 11/21 was a beautiful day here for field day... loaded up the mobile
mortgage with a couple bags containing:

ic-703
ft-817
mp-1
17M hamstick
SD-20 (crappie pole)
LDG Z11
homebrew 4:1 balun
Norcal BLT tuner
log book
(2) SLAs; 4.5Ah, 7.5Ah
(2) Radio Shack SW antenna reels
25' of 300-Ohm twinlead
(2) large nails
yellow nylon cord
swiss cheese on rye sandwich
small thermos of java
misc coax

- went to a local park and found an open site with a picnic table

- the table was metal! whoo hoo! instant groundplane! clamped the
MP-1's base to a corner, screwed in the hamstick, attached coax to the
703...

- bungee'd the SD-20 crappie pole ($19 from World Radio), attached the
feed for the 300-ohm twinlead and each leg of RS antenna reels...

- strung out the reels, attached yellow cord, pushed nails in ground...

- pushed up the SD-20 to a height of 20 feet, attached end of twinlead
to the balun then coax to Z11 and 817...

- i originally intended to do some sort of scientifc measurement of
how well the 703 matched the hamstick, and subsequently, the dipole...

- however, when i fired up the 703, dialed to hfpack's freq (18.157.5)
and hit the tune button, i found myself in a QSO with operators from
Texas, Montana, and Illinois - at 8W!!! not too shabby from a park
picnic bench in the DC metro area...

- i fired up the 817, dialed into the same freq and heard.... NOTHING!
no matter what i did, the rig seemed deaf... this went on for 20
minutes, until like the idiot that i am, i remembered that i had
removed the SSB filter the day before (to put into another rig), and
the 817 was still 'menued' on the SSB filter... changed the menu
setting, and life was good... reception restored...

- for the next several hours i had a blast! bright blue sky, a cheese
sandwich, sips of coffee, and nice chats with folks in the U.S. and a
nice ham in Ontario...

- one YL walked by with her kids and said, "Oh, you like fishing? Are
you getting set up for fishing?" (after seeing the SD-20)... i
laughed, and said, "Oh yes, I'm going fishing!" (for QSOs!)

- the 703 and 817 both performed very well... the only way for me to
determine which rig i like better is to use them side-by-side...

- i like the 817 and its multi-mode, multi-band capabilities... it
will remain my 'travel' rig, as all i need is the BLT tuner, some wire
for an antenna and counterpoise, along with AA batteries...

- but the 703's ergonomics are very appealing, and i found myself,
after only 24 hours of playing with rig, falling in love with the way
i can use the rig... (the deep Setup menu is a little funky: power
off, power on to the menu, then power off... but i can live with that...

- when i got home and unpacked, i set up the 703 on the back deck with
the MP-1, spread the four radials, and had a QSO with a nice op in
TX... at 5W...

- btw, who says the bands are in bad shape? 17M has been kicking butt
the last 48 hours?

- oh, and if you want to see a couple snaps of my setup, browse to:

Thanks for the reply Bill. I have the big brother 706Mk2G and have
had lots of fun with it. Been itching to try QRP with a rig designed
with that purpose in mind particularly on PSK. Been working on my CW
as well as I'm pretty rusty at it after a long absence from ham radio.

I originally got the 706 to take portable but it works so well as the
base rig at present along with the LDG AT11-MP and the 160 meter
sloper. Portable QRP has a strong alure for me so look forward to
packing the 703 along with me when I can long with the MP-1 super

| 603|603|2003-11-24 09:02:35|gzustway|Afraid to buy IC-703|
I have been waiting to see more positive reviews of the 703 before
getting one. I have been wanting a one rig does all for some time.

Last year I bought an FT-100D (even after all the problems they had)
thinking I could take batteries and QRP with it but have power when I
needed it. Well the fans were too loud, everytime I keyed sounded
like a jet plane. I sold it and now the guy who bought it says the
finals are shot.

So this year like a fool I fall for the Ft-857. And guess what the
Rxr is deaf out of the box. So I'm getting a refund.

I had though about the FT-817 but Yaesu is really leaving a bad taste
in my mouth. Plus isn't the 817 a bit hard of hearing too?

So I saw the 703 and heard problems. I want one but I'm starting to
wonder if Japan can build a good radio anymore. Maybe because of the
internet we hear more about it than years ago but there seems to be a
trend on radios with the Microsoft bug. You know "how would you like
to buy my product and beta test it for me". I don't think there is
enough positive feedback for me to buy a 703.

Maybe I should just build an Elecraft then I'd be my own QA.

- sorry to hear about your rigs... i guess i'd be a bit gun shy myself...

- i have an 817 and an 857, and they have been been good to me... by
the way, the receiver strip in the 817, 857 and 897 are the same...
(this was attributed to a Yaesu rep at a local ham meeting, according
to a fellow ham) ... if i have any complaints, i think the sound in
the 857 is a bit 'mushy' on HF... not so on the 817...

- the 857 'deafness' can possibly be attributed to a mis-setting in
the 'deep'[factory] settings menu... this info has been discussed on
the 857 group...

- 'do-it-all' (aka DC-to-daylight) rigs by design (if my Elmers are
correct) won't have as good receiver as a rig designed specifically
for amateur bands... there just isn't room on the board... in light of
this, the 817 is quite remarkable...

- the 817 is a nice rig though... quite handy, and i've had 3,500+
mile phone contacts at .5W (one-half watt)... i haven't found the
recv'r lacking...

- that said, i really like the 703... i have a unit in the early
serial number range... am i worried? nah... i'll just send it in for
repair if a problem crops up... i've been having a blast with it so far...

- location and a good antenna helps (up 2,600 feet, 40M wire dipole up
60' in a tree)....

The 703 was returned repaired within a week (thanks to Chris Taylor at

I don't think that it is too wise to go by "what you hear" or eham reviews:
the latter can hardly be classed as objective.

All in all I think that the 703's RX beats the 817 hands down - although it

Sorry to hear about you past experiences with some what appear to be
decent rigs. One thing about internet reviews on any product, you
get to the point that you're afraid to buy anything from all the
negative reviews that are posted. From my perspective there are very
few objective reviews posted either positive or negative on the
internet regardless of the product or service being reviewed.

The amazing thing however is with all the reported failures of the
FT817 finals folks love the little buggers and keep on buying them.

Like you I was aprehensive about buying the 703. I walked into the
AES store in Milwaukee last Saturday and walked out with a new 703
with the plan if it goes bad I'll get it repaired. Actually I was
more worried about the XYL's reaction to the purchase than failure
of the rig.

I bought my 706Mk2G at this time last year after I read some very
negative reviews on e-ham.net and haven't regretted my decision one
bit.

Regarding an Elecraft, they have a loyal following and from all
counts seem to be a fine piece of work. I really liked the concept
and gave serious consideration to it but the 703 won out.

Good luck with your decision either way.

| 610|610|2003-11-25 00:12:46|Alan Waddington|2nd attempt at portable operation successful|
Last week I attempted to operate portable & had keyer lockup problems. A
few modifications have solved the problem & successful local communications
were made from the office car park this lunchtime.

The antenna is a shortened vertical on 80m on a small groundplane with an
additional grounding wire. It did not appear to be resonant at the expected
frequency, which was probably due to an inadequate earth and RF flowing back
up the coax outer. While the earth situation is still poor, a choke
consisting of 7 turns of RG58 at the feedpoint seems to have substantially
reduced RF on the coax sheath & the antenna is now resonant much closer to
the expected frequency.

Unfortunately the keyer still tended to lock-up. I tried the eathing mod
suggested earlier in this group, but it didn't solve the problem. Then
additional 10uH filters were wired in series with the keying lines in the
plug (which helped a bit). Capacitors were added, but took too long to
discharge on key release so were removed. Lastly the lead to the key was
shortened to about 18", which was more effective then any of the other mods,
but means the key must be placed close to the radio.

Now i need to work on my cw. Having loads of fun.

Hi Ed,

Thanks for the reply. On the 706, How loud are the fans on this rig
when yo key it? Do they come on every time you key? One thing I
liked about the 706 it apears some protection sensing circuits are
right on the finals themselves and on the output of the filter
assembly. A good design. The Yaesu FT-100 and Ft-857 have nothing
at the finals. So it the filter assem. or T/R relay goes the finals
will fry. And you will get no warning. Icom seems to have done a
better job in the circuit design.

| 612|603|2003-11-25 15:53:59|flhtci97|Re: Afraid to buy IC-703|
Well this is my opinion and others will likely disagree. The 706
will run pretty warm even on receive alone. The fan kicks in when
the rig gets to a point it trips the thermocouple and you will
definitely hear it. Is it at an annoying level? To me no but to
others yes.There has been numerous posts on this subject on the
IC706 Yahoo group and would be a good source for you to research.

In regard to the 703, I made a PSK contact yesterday on 20 meters at
6 watts and the rig hung in there even with my very limited typing
speed. With that being said the the transmitter section was
definitely doing it's job. Later on after doing a bunch of listening
I made a 17 meter SSB contact at 6 watts with a station just north
of Seattle and received a 5x5 report. Not too bad from southern Iowa
with low power and a 160 meter sloper and the considering the other
station was running 300 watts into a 4 band quad.

By the way the antenna tuner seems to work decent if you have an
antenna that can be even somewhat resonant. I have less than top
notch, well tuned antennas at my station.

I'm off work this week so I will get a chance to abuse the 703 a bit
and see how it holds up. I really thik that the 703 is a fine little
rig and with this being the premiere production runs ay Icom there
are bound to be a few bugs to be worked out.

I have had the 703 since last spring and just purchased the 706 in
Ft. Wayne. Would not give up either one. The only glitch in the 703
is making sure the shield on the keyer cable is grounded. Solved the
keyer problem.

Hello,

I am anavid QRPer and have a brand new UNUSED yaesu FT-857 in the box
I like to swap for a clean functional Icom 703plus. It is for an
application where I need to work off of a small battery and accdording
to the specs it drweas a bit less than the 1.5 amps the 857 draws. If
anyone is interested, ping me on droptop@... or give me a call
on 602 999-7606

Hello!
My call sign is KF4CNM. I am new to the Ic-703 message board. This is
my first post.
What portable antenna should I use for backpacking and P/M,B/M and
also for an attic antenna. Do to subdivision covenants and
restrictions I need to have a good attic antenna also.
with counterpoise wire and those that don't need a counterpoise wire.
Thanks for allof you helping me to decide on which is the best
antenna to purchase.

Gary,

Asking for the "best antenna" is like asking for the best brand of
bologna...

First, before you BUY something, investigate building it yourself.

Portable, /PM, manpack antenna... The MP1 or PAC12. I use a couple different
for different uses...

I have a surplus AS-1887 - extremely rare, 2 to 18MHz, tapped coil base
loaded whip.
I also have one that is without the tapped coil, I do not know the model
number. I found 5MHz coils that fit this antenna. I also have a "TruckerII"
CB antenna that works with the antenna tuner down to 12 and 17 meters.

These are my manpack antennas.

I would like to build a PAC12. I have also considered a MP1 type too. Maybe
if I find 12 foot flexible tape measures at Parts Express for $1.00 again,
I will pick one up and use it as the whip part of an antenna.

Attic antenna, I would put up a multiband dipole. Maybe a loop...

You can do a lot with a hunk of wire and a good auto tuner.

--- In IC703@yahoogroups.com, "gary jamerson" wire.
Since the size of any portable or mobile antenna is small compared
to the wavelength, it will need a loading coil to bring it to
resonance. This has the side effect of making the antenna narrow
band - maybe 20kHz on 160m, 40kHz on 80m and so on. Thus without
any means of adjustment, a small antenna will only match well on a
single band (or for the lower frequency bands, only a portion of the
band). For multi-band operation, it will be necessary to have
selectable taps on the loading coil and some means of fine
adjustment, such as a variable length whip. Therefore changing
bands requires some manual adjustment. It can be tricky to fine
tune the antenna to be resonant at the frequency of your choice,
which is where an antenna analyser becomes really useful.

Antenna options include a vertical over a ground-plane, a vertically
oriented dipole, a horizontally oriented dipole (e.g. a buddipole)
or a long wire.

The MP-1 is a commercial example of a shortened vertical. The main
issue is the requirement for a groundplane of some sort. A number
of wire radials will do for portable operation, while a trailing
counterpoise would work for mobile operation (but would tend to snag
on things. For your attic, one of the Hustler mobile antennas with
a suitable length counterpoise may be worth considering.

The Buddipole is a commercial horizontal shortened dipole for 40m
band and above. Obviously this leaves 160m & 80m operation in the
cold. Since no ground plane is required, you could lash it to a
backback for portable operation, but you'd need a lot of space where
you were walking. Also being very low to the ground would result in
the signal radiating up fairly steeply, so it would only be good for
local contacts.

I haven't seen any vertical shortened dipoles for mobile operation
(probably due to the height required), although you could try
mounting a budipole vertically. I suspect that this would not be
ideal however since the capacitance to ground would be different for
each side of the dipole, so they probably need to be different
lengths to be resonant at the same frequency.

And there is the faithful long wire. This is still a good option
for lightweight portable operation, but will need an external
autotuner to match it.

The above were my thoughts whilst trying to decide on a compact
easily erectable antenna for local portable operation. Of the
above, only the long wire (suitably high) is likely to pull in any
DX. It's really a matter of considering how you intend to use the
antenna, designing something suitable, then seeing what commercial
offerings are close to what you want when deciding whether to make
or buy.

Lastly, I just struggle along like everybody else, so can't lay
claim to any special knowledge in this area.

| 619|615|2003-11-26 16:16:58|John Oppenheimer|Re: Ic-703+ antennas|
I'm going to try the short story about counterpoise usage, maybe it will
help you with your selection.

1. A balanced antenna, eg. dipole, does not need a counterpoise.

2. An unbalanced antenna eg. vertical, almost always needs a counterpoise.

3. The unbalanced antenna feed impedance is directly proportional to the
required counterpoise impedance, the reason for the "almost always" in 2
above. A 1/4 wave vertical textbook impedance is 35 ohms, it is rather
challenging to get a counterpoise down to that impedance. Whereas, an
end feed 1/2 wave antenna, feeding at the high impedance point, may not
even need a counterpoise.

Making a counterpoise:

1. A ground rood is almost never a good counterpoise.

2. A 1/4 wave length wire in free space makes a good counterpoise. An
example is the ground plane vertical antenna with 1/4 wave radials.

3. Lots of wire radials (length not too critical) laid on the ground, or
just under the ground, makes a good counterpoise. Many detailed articles
on how many and lengths out there.

4. The house plumbing, out of your control, you may get a low impedance
or a high impedance point, you never know unless you measure it.

Hi All

I had the good fortune to field test the Icom-703 this past August. The
results of the field test were published in the October issue of "Radcom",
the Journal of the Radio Society of Great Britain.

For the field test I purposely used lightweight, easily carried antennas and
operated both portable (/P) and pedestrian mobile (/PM).

For the portable work I used a long wire (W3EDP) plus earth spike and
counterpoise, and a Buddipole. The 703 worked extremely well with both
these antennas - with 10w I did not feel "under powered" on 40m at midday!
and made a trans - Atlantic QSO on 17m.

When /PM I had a long QSO on 20m with an Australian station. This was using
the rig at 10w (with 7Ahr gelcel) feeding a 15 ft. whip antenna fastened to
my backpack. I used a single, dragged counterpoise cut about 10% less than
a quarter wave for the band.

For all of the tests I used the built in antenna tuner and a 4:1 balun. The
tuner coped extremely well - much better than Icom claims for it.

In my opinion it is a great little rig and a joy to use.

I do not own one because it is a little underpowered for my own speciality -
Pedestrian Mobile DX. However, the QRP HF enthusiast should seriously
consider it.

Anyone seeking advice re. portable and pedestrian mobile antennas should
peruse the archives of the Yahoo group "HFPack"

Cheers

Tom - GØSBW

BTW My regular pedestrian mobile rigs are the Alinco DX70TH (at 50W) and a
FT817/HL50-B combination.

I forgot to mention that all the contacts were SSB.

Judging from the Eham reviews, I would be afraid to buy a 703.

I use a 703 (HF only). My first 703 was DOA after 4 days (no
transmit). I sent it in to the dealer and received a new 703 in a
few days.

The keyer "latching on" is a problem, but is easily solved by
grounding the key jack ground to the chassis.

I like the receiver of the 703 and the tuner has exceeded my
expectations. So far it has tuned random length end feds, resonant
dipoles, a 58' dipole fed with 300 ohm ladder line on 40-10 meters.

With all the negative comments made about the 703, it makes me wonder
how long the finals will last on this 703. Since it has been more
than 90 days, I think any repairs would be on my nickel.

I just returned my 703 that I purchased a week ago for AES
Milwaukee. The output power went south after 4 days as well. The
serial number of the unit was 1801191. I know there have been
failures with units with more recent serial numbers that the unit I
just returned. I have requested that AES exchange the unit with the
most recent serial number that they have in inventory but that may
not be a whole lot better than what I have now. It will probably be
the week after next before the new unit arrives.

The serial number of the rig was 1801191 and I just sent it back
yesterday after the power output went south. I really like the rig
so I'm confident that Icom will get the issue resolved.

I requested that AES send me the most recent unit they had in stock
but there have been failures in the 18014XX range as well. The first
two digits of the serial number is the revision number of the the
unit. Revision 18 OTH (other?) is pretty common in the US it seems.
There is a revision 15 USA but this shouldn't make a dufference in
performance or quality I don't believe.

Why I asked about your serial number, is there comment comments similar
to "they fixed that." I was just wondering if there has been enough sold
to even drain the first production run, however big that may be. 1000?

I bought one from AES in October, serial number is 1801436, 245 unites
newer than yours. N4QA with serial number 1801416 acquired used in
July-ish. N4QA also needed to fix the transmitter section.

Did you power yours with 13.8V or a 12V battery. I have only powered
mine with a SLA 12V battery, which starts at about 12.5V fully charged.

I will be interested to find out what AES sends back to you.

| 628|603|2003-11-29 20:49:02|flhtci97|Re: Afraid to buy IC-703|
Jim at AES Milwaukee simply instructed me to return the unit for
exchange. As far as an comment like "they fixed that" was not
communicated to me. Jim was receptive of finding the most recent
unit they have in inventory to exchange. However what they have in
inventory my be not much better than what I have currently.

I agree with you that the first manufacturing lot may not be

Hi Guys,
kc5uoj, Mike, here.
I too am anxious to purchase a 703+. I am a member of the HFPack group
and I think the 703 will with its' remote faceplate will be ideal for a
pedestrian mobile setup I'm assembling. I intend to drive my HFPacker
amp with it for a 35-40w output SSB setup.
I would like to be intrepid and go ahead and be a beta tester for Icom,
but I don't need another aggravation right now, so...
I finally got some time off work so I decided to put together some data
on the 703.
The purpose for me personally is to try to determine a point to purchase
a 703+. I know others are in the same position so maybe this will be of
service to them too.
I sifted through the eham reviews, and previous posts on this group to
collect data. I compiled a very small database in Excel. If anyone is
interested I could e-mail the file to you. Or, post it to the files
section, but I don't see one for this group.
I only recorded data from posts or reviews where someone was kind enough
to include their serial number.
Hopefully we can see a trend toward better units at some point soon and
maybe correlate that to a range of serial numbers. I know Icom will get
the problems worked out, but how do we determine when that has happened?
As stated in other posts, people tend to post more about troubles than
they do about positive experience so a big part of the equation may be
missing here! I don't have enough data points yet to determine much, but
PA Driver problems are still being reported on some of the highest
serial number units I could collect data on. (John KN5L is the highest
I've seen at S/N 1801436) Thanks John! I think Johns' is still OK as far
as driver failure. Lets hope it stays that way.
If anyone would care to share their serial number and experiences with
the 703 I would be glad to add them to the database.
The following are the categories of data I am collecting, separated by
commas,(? In data fields = unknown, I estimated some of the dates based
on posting date or comments);
S/N, 703+, Drivers Fail, Date Purchased, Owners Call, Mis-marked
Faceplate, Dealer, Keyer Problem.

Here is the data so far, I'm not sure if it will format correctly!

1801436 No No Oct KN5L Yes AES ?

1801416 No Yes May N4QA ? ? ?

1801363 ? Yes May W9HC ? AES ?

1801191 No Yes Nov N0EHQ ? AES/Milw ?

Assuming this formats so it makes some sense, please let me know if I
need to correct anything.
Thanks to everyone who has included their S/N in posts so far.

I hope this doesn't add noise to the data but it's interesting to
see 3 version numbers represented in the failures you have listed.

The version number is indicated by the first two digits in the

Version 12 = Eur-1, Version 15 = USA-1 and Version 18 = OTH-1

Thanks for the pointer Ed.
From the admittedly small amount of data collected, it seems like the 12
and 18 versions are 703+ models, and 15 are HF only 703's. But, 50mhz is
not listed at all among the Tx or Rx Freqs for any of the listed
versions?
Interesting that the guaranteed TX is stated slightly differently for
the version 18 too.
I'm trying to figure out what OTH might be an abbreviation for?

As you say, It "may not tell us much", but it's interesting to play
detective!

The driver transistor fail about 2 months ago, i send the rig to icom spain
and return it in 2 weeks.
The rig work marvelous, but westerday, in cq ww cw y see the same faliture
symthoms of the driver (intermitent PA fail).
I believe that tomorrow the problem will appear again. :(

My opinion about 703 is:
The rig is vy fun to operate, but the fail of driver rest too many points in
the global apreciation.
The rf return in the key jack is tribial to solve.
The garanty solve the problems but isn´t fun send and send again the 703 to
icom.

On the other hand:

The tunner is vy much better than excepted.
The DSP is vy good.
I have de lc 156 and is vy fun to do camp operation with it.
The rx current and power saving facilities is vy good. In portable i use 3
amp 12v gel bat or 7 amp gel bat
in spite of the problems he would buy the 703 again.

Well I have a 1501001 703+, face plate is marked as such and the rig was purchased in May at Dayton
from HRO. No failures yet, the rig has not been used with the internal keyer, just a straight key
with no RF feedback problems. It's been used a lot on 6 FM, and HF SSB, CW since the purchase date
and (fingers crossed) no failures.

I think this version list references the 703 model only (probably created before the 703+ was
released). Since I have a #15 series radio that is 6 meter capable and marked as such... there must
be some 703+s in the #15 serial range.

Hi Eric,
Thanks for taking the time to add to the database.
Glad to hear you have had good results.
It's certainly an eye opener to see a 703+ with a 15 Version number!
I think your assertion that the version list is outdated is probably
correct. Still not much data to go on, but the 15 series Rigs seem to
have a slight edge over the 18 series at this point in the category of
driver failures.

Thanks and 73 de kc5uoj - Mike

Sorry guys,
I made a mistake in an earlier post when correlating version numbers
with the two models, 703, 703+.
The collected data shows versions 12 and 15 are 703+ and version 18 is
HF only 703.
Guess I was doing a bit too much multitasking between this and building
my KX1. The data is just what I have collected from this groups
archives, recent contributions, and eham reviews, and speaks for itself.

Seems like the repaired units fare well. Once they're fixed, they
seem to stay fixed (with one exception that I've seen). Therefore,
one might be better off getting a dead unit repaired rather than
taking chances with a dealer swap for a new one -- at least until it's
well documented that the problem has been fixed at the factory and the
revised units are on the dealer's shelves.

And here's yet another one:

S/N = 1801227
703+ = No
Driver Failure = Yes, probably (in ICOM service dept now for dead TX)
Date Purchased = October 2003
Owners Callsign = KC5UN

Keyer Problem = Yes, easily fixed with key jack ground to chassis

Thanks for adding your data.
We now have data for 17 703's!
Glad to see no trouble with yours Rich!
So far no version 15 rigs with reported driver failures, but we have
almost twice as many version 18 rigs in the database with roughly a 50%
failure rate. Still a pretty small sampling of data to base any decision
on though.
Hope you are enjoying your new rig.

I have updated the serial number data. http://kn5l.net/ic703/ Send any
corrections to me.

I have added the Dec CQ review rig, I was able to pull the SN off of one
of their pictures in the review. It is interesting to see where the
review rigs fit into the table.

And finally, I have been pushed down from the top of the list by VE5KC,
and his rig is the first HF only to have the proper faceplate.

A thought, I was thinking about removing the CW problem column, we know
that they are all the same, and adding a power source column. I have
only used a battery with a maximum of 12.5V. An AC power supply will
supply 13.8. I'm just wondering if the PA failure is dependent on supply
voltage. Comments/thoughts?

Hi John and others:

I have used only AC-fed power supplies with my 703: one gives an accurately
measured 13.801V, the other 13.692V.
When my drivers failed it was connected to the 13.801V PSU through the full
length of the long standard power lead.

I can't believe that .109V would be the difference between frying the
drivers or not: Icom specify 15.87 as the upper limit. That means that I'm
over 2V under the peak limit, and that's not allowing for the voltage drop
in the cables.

What WON'T do the rig any good is starting the car with the rig switched
on....that can produce some nasty transient spikes.

| 665|657|2003-12-02 00:40:43|flhtci97|Re: Serial Number Data updated|
John,

The faceplate on the rig I just returned to AES was HF only. I
talked with AES today and asked them to replace the version 18 HF
only rig with a version 15 HF+ rig.....at extra cost of course. They
did however confirm what they had in stock was indeed version 15 HF+.

It's good to see folks responding to the rig data request as that is
what prompted me to ask for the replacement rig to the HF+ model.
There are not a lot of data points but at least it seems to give an
indication of a trend.

Ed,

Good to work you on our "replacement" '706s this afternoon. Good luck
with the new 15-series rig.

For what it's worth in the stats department, my '703 (s/n 1801227 in
the table) failed while using it mobile. The rig's voltmeter
indicated 14.2v on receive when the car was running above idle, well
below the 15.9v upper limit, but still, perhaps there's a
correllation. I avoided starting the car with the radio on.

Tom, KC5UN

Hello friends,



I am Peter, DL2FI. Due to some lack of time I didnt response to this list up
to now.



The serialnumber of my IC-70l is 1201067

Probably it is one of the very first in Europa because I got it before any
dealer got one.

I received it directly from ICOM because I had to write a test review for
the German Ham Radio Magazin FUNKAMATEUR. Unfortunately it was before Icom
decided to reduce the price, so I had to pay 200 EURO more than all other
buyers. :-(



On the front side it is labelled HF/50 MHz Transceiver IC-703



The summary of my test review was: the best receiver since I built and
tested my K2 Serialnumber 000009 (fieldtest version) :-)



There was a little problem which could be resolved with the help of some
ICOM technicians: Using an external keyer electronic caused the TX to hang
in Transmit state. The reason for this hang are 2 "forgotten" capacitors
next to the keyer jack. The Pads are on the board, but they didn't tell the
robot to place the 4n7 caps there.



A couple of weeks ago, transmitter stopped transmitting. Of course I did the
repair by myself. Failure: There is a litte GaAs MMIC amplifier between the
bandpasses and the driver. After replacing it, all was ok again.



My 703 is equipped with the INRAD 400 Hz filter which is superb either for
CW or PSK31.

I run mine #1501001 with both a 13.8v PS and a 12.6v SLA battery. Probably about equal time on both

| 669|639|2003-12-02 15:08:30|Woody Pride|Re: Rig Serial Number Data|
This indication of two missing capacitors causing the keying problem has me
wondering. If these are truly missing with the pads reflected on the
circuit board, why is Icom not offering to correct this omission for those
who have purchased the defective units? I've read of the missing capacitors
once before, however there doesn't seem to be much widespread talk about it.
Everyone appears to be choosing to ground their key jacks rather than have
Icom install the missing components.

This also led me to a comparison of the key grounding mod picture posted on
KN5L's website to Icom's 703 Service Manual internal photos. In the
vicinity of the key jack, there appears to be some significantly different
components between the photos, one of which is a capacitor next to the key
jack. However, the capacitor exists in the unit requiring modification and
not in the Service Manual photo (opposite of what you'd expect). Now there
may be a bit of difference in that the posted photo and the one in the
Service Manual may be 703/703+ units respectively. However it does lead one
to want to confirm whether in fact this problem is caused by the Icom
"robot" forgetting to install the two caps mentioned.

I don't yet have a 703 myself or I'd compare the Service Manual photos to
the unit itself. Has anyone else done this comparison? As there may be
some slight differences in the 703/703+ units, there would need to be a
comparison of each. There may also be other ways of determining which unit
is reflected in the Service Manual photos. Either way, it would seem an
easy confirmation from Icom whether it is these missing capacitors causing
the problem. Does there appear to be indications of capacitors missing near
the key jack in the units members of the group have purchased?

I own a new IC-703+, as it were a belated birthday gift from Dad to
Dad. My joy is unfortunately clouded at present.

As soon as I start my IC-703+, the VFO immediately starts running in
fast pace all way down and then at once jumps up to 50 MHz. The loop
begins again. No used frequency will stop it. With S2 SCN I cannot
stop the VFO. The decimal point does not blink. Thus the VFO is not
in scanning mode.

Already twice I did a RESET. It did not help.

Once I was able to stop the VFO. Do not ask me how it happened. The
rig started working normally. It could be switched on and off. S2
SCN switched the scanner on and off. I made my first contact on 18
MHz with 4 W SSB. Distance approx. 1000 miles. The next morning
however the equipment behaved erratic again, as described above.

The dealer said he has never heard of such a case. The equipment must
be sent back to ICOM. However before I go through all this trouble, I
would like to hear the opinion of 703-users. It would be very
embarrassing for me to hear later, that the equipment is o.k., but
just one setting was improperly made.

What mistake did I make? I am desperate.

My set-up is: IC-703+, serial # 1501095, power supply 12.8 V,
vertical antenna or dummy load.

Every and all assistance will be greatly appreciated.

As soon as I start my IC-703+, the VFO immediately starts running in
fast pace all way down and then at once jumps up to 50 MHz. The loop
begins again. No used frequency will stop it. With S2 SCN I cannot
stop the VFO. The decimal point does not blink. Thus the VFO is not
in scanning mode.

Already twice I did a RESET. It did not help.

Once I was able to stop the VFO. Do not ask me how it happened. The
rig started working normally. It could be switched on and off. S2
SCN switched the scanner on and off. I made my first contact on 18
MHz with 4 W SSB. Distance approx. 1000 miles. The next morning
however the equipment behaved erratic again, as described above.

The dealer said he has never heard of such a case. The equipment must
be sent back to ICOM. However before I go through all this trouble, I
would like to hear the opinion of 703-users. It would be very
embarrassing for me to hear later, that the equipment is o.k., but
just one setting was improperly made.

What mistake did I make? I am desperate.

My set-up is: IC-703+, serial # 1501095, power supply 12.8 V,
vertical antenna or dummy load.

Every and all assistance will be greatly appreciated.

It is possible. Some supplies are autoswitching. This means, they will
output the right voltage provided the input voltage is inside the specified
range. You may check this in the documentation.

Hello ALL:

Being an Electronics Technologist my curiosity got the best of me so
I decided to take a close look at my 703+(SN 1501405) for the rumored
missing capacitors on the key line. I removed the main board from the
radio to inspect the bottom to see what components were installed in
the key line on my unit.

There are two components, EP6923 and EP6924(S Bead)connected in
series. One end of this string connects to the ground of the key jack
and the other end of the string connects to ground of the circuit
board. An ohm meter measurement revealed that the the key jack ground
is floating 1.2 ohms above circuit board ground.

On the key jack dash(DASK) line there are EP6921 and EP6911(S Bead)in
series. One end connects to the DASK of the key jack and the other
end to the bus line. Likewise for the dot(DOTK)line there are EP6922
and EP6912(S Bead) in series with one end connected to the DOTK of
the key jack and the other end to the bus line.

However, interestingly I found that my 703+ has "TWO" extra surface
mount capacitors (don't know the value) connected in the key line
which are "NOT" shown on the schematic. One capacitor is connected to
the junction of EP6921 and EP6911(dash line) and the other end of the
capacitor to circuit board ground. The second capacitor is connected
to the junction of EP6922 and EP6912(dot line) and the other end to
circuit board ground. These capacitors are NOT an afterthought as the
solder pads for these devices are silk screened on the board.

Also, there are two additional elongated solder pads in the dash and
dot lines of the key jack on the circuit board. These pads are much
longer and larger then the regular solder pads normally employed for
surface mounting the small by-pass capacitors. It was reported in
another posting that the rumored missing capacitors should be
installed at these pads. Upon close inspection I found that if
capacitors were installed across these pads the capacitors would be
connected in "PARALLEL" with component EP6921 and EP6922(S Bead)
respectvely defeating the purpose of the S Bead functionality.
Personally I feel that these elongated solder pads were not designed
to house the rumored missing capacitors and that the robot did not
forgot to install the rumored capacitors. A robot only does as
instructed(programmed, they do not forget or think for themselves.
There is my two cents worth.

The 703 database continues to grow!
Thanks again to all contributors.
Still a pretty small sample, but here are some things I think I am
seeing.
BTW, I'm no statistics whiz, I'm an ex building contractor turned CNC
machinist.
I really was just trying to put the issue of problems with the 703 in
proper perspective (if possible), so I could make a decision WHEN to
purchase one. I think it's a great rig and perfect for the HF Pack
setup I have in mind. The great receiver specs. And removable faceplate
just ice the cake.
Glad to see some suggestions to make the DB more useful.


Version 18:
Serial Numbers representing a range of 391 units. #1084 to #1475
#1403 and #1416 were purchased back in May 03. Since they are near the
top of the range of numbers we have represented in our data, I believe
the original production run of rigs are still being offered for sale.
#1436 was purchased in Oct '03. How many rigs Icom produced in the first
run is anyone's guess. Any Ideas from Mfg. gurus?
Version 18 is still showing about a 50% rate for driver failures.

Version 15:
Serial Numbers representing a range of 404 units. #1001 to #1405
So far all version 15's are 703+
Hard to determine much from this small amount of data, but the range of
Serial numbers are similar among all three versions.
Version 15 still showing no driver failures. I looked on eham and
couldn't find any statements to link a 703+ to a driver failure, but
it's easy to drop the + when discussing 703's.

Version 12:
Serial Numbers representing a range of 308 units.#1067 to #1375
An even smaller data sample with only one driver failure.

John Oppenheimer, KN5L is really working hard keeping the table updated
on his webpage.

Thanks John!

Thanks very much for your post Dietmar. I think the original contention was
that the robot wasn't correctly programmed to install the rumored missing
capacitors. Not that "it" forgot to install them but that the programmer
forgot to include their installation in the robots instructions. A bit of
word confusion from the original post.

Seeing that you have a 703+ which has the "extra" capacitors you described
not being on the schematic, does your unit have the keying problem requiring
the grounding of your key jack? (data replaced with power supply info on
website) If it does, I guess we know the "extra" capacitors aren't the
"missing" ones.

If you don't have the keying problem, then it would come to a review of the
capacitor installation on one of the units that does have the problem. Do
these units not have the two capacitors you describe missing from the
schematic, yet have locations for them silk screened on the circuit board?

It seems this should either be verified or dismissed, as it was reported
that it was an Icom technician who identified the missing capacitors. The
question would be, if the capacitors are truly missing in the units with the
keying problem, while grounding the key jack appears to be a sufficient
workaround, is it the best solution for optimal performance of the rig?

I guess a large part of this issue could ride on whether or not your unit
has the keying problem. It is very interesting that Icom identified two
missing capacitors and you found two capacitors not on the schematic. Just
coincidence?

Woody,

I got a photo directly from ICOM after I contacted them at the German Ham
Radio. There are also two missing caps at the processor socket, but because
there is some shielding above I didn add them (no time, too much work).



The reason that they donÂ’t spread out this info seems clear to me. How many
of IC703 owners realy use an external keyer?

Betreff: RE: [IC703] Rig Serial Number Data



This indication of two missing capacitors causing the keying problem has me
wondering. If these are truly missing with the pads reflected on the
circuit board, why is Icom not offering to correct this omission for those
who have purchased the defective units? I've read of the missing capacitors
once before, however there doesn't seem to be much widespread talk about it.
Everyone appears to be choosing to ground their key jacks rather than have
Icom install the missing components.

This also led me to a comparison of the key grounding mod picture posted on
KN5L's website to Icom's 703 Service Manual internal photos. In the
vicinity of the key jack, there appears to be some significantly different
components between the photos, one of which is a capacitor next to the key
jack. However, the capacitor exists in the unit requiring modification and
not in the Service Manual photo (opposite of what you'd expect). Now there
may be a bit of difference in that the posted photo and the one in the
Service Manual may be 703/703+ units respectively. However it does lead one
to want to confirm whether in fact this problem is caused by the Icom
"robot" forgetting to install the two caps mentioned.

I don't yet have a 703 myself or I'd compare the Service Manual photos to
the unit itself. Has anyone else done this comparison? As there may be
some slight differences in the 703/703+ units, there would need to be a
comparison of each. There may also be other ways of determining which unit
is reflected in the Service Manual photos. Either way, it would seem an
easy confirmation from Icom whether it is these missing capacitors causing
the problem. Does there appear to be indications of capacitors missing near
the key jack in the units members of the group have purchased?

Hello friends,



I am Peter, DL2FI. Due to some lack of time I didnt response to this list
up
to now.



The serialnumber of my IC-70l is 1201067

Probably it is one of the very first in Europa because I got it before any
dealer got one.

I received it directly from ICOM because I had to write a test review for
the German Ham Radio Magazin FUNKAMATEUR. Unfortunately it was before Icom
decided to reduce the price, so I had to pay 200 EURO more than all other
buyers. :-(



On the front side it is labelled HF/50 MHz Transceiver IC-703



The summary of my test review was: the best receiver since I built and
tested my K2 Serialnumber 000009 (fieldtest version) :-)



There was a little problem which could be resolved with the help of some
ICOM technicians: Using an external keyer electronic caused the TX to hang
in Transmit state. The reason for this hang are 2 "forgotten" capacitors
next to the keyer jack. The Pads are on the board, but they didn't tell
the
robot to place the 4n7 caps there.



A couple of weeks ago, transmitter stopped transmitting. Of course I did
the
repair by myself. Failure: There is a litte GaAs MMIC amplifier between
the
bandpasses and the driver. After replacing it, all was ok again.



My 703 is equipped with the INRAD 400 Hz filter which is superb either for
CW or PSK31.

I sent my 703 back to WIMO ten days ago to have the modifications done under the warranty and got it back from WIMO today. I can't wait to try the rig - though I hadn't been plagued lately with the "hanging key" issue. WIMO told me I was the first customer to report about this issue - which surprised me.

Thanks again for all the helpful advices from the group. The 703 is a great rig.

is floating 1.2 ohms above circuit board ground.

On the key jack dash(DASK) line there are EP6921 and EP6911(S Bead)in
series. One end connects to the DASK of the key jack and the other
end to the bus line. Likewise for the dot(DOTK)line there are EP6922
and EP6912(S Bead) in series with one end connected to the DOTK of
the key jack and the other end to the bus line.

However, interestingly I found that my 703+ has "TWO" extra surface
mount capacitors (don't know the value) connected in the key line
which are "NOT" shown on the schematic. One capacitor is connected to
the junction of EP6921 and EP6911(dash line) and the other end of the
capacitor to circuit board ground. The second capacitor is connected
to the junction of EP6922 and EP6912(dot line) and the other end to
circuit board ground. These capacitors are NOT an afterthought as the
solder pads for these devices are silk screened on the board.

Also, there are two additional elongated solder pads in the dash and
dot lines of the key jack on the circuit board. These pads are much
longer and larger then the regular solder pads normally employed for
surface mounting the small by-pass capacitors. It was reported in
another posting that the rumored missing capacitors should be
installed at these pads. Upon close inspection I found that if
capacitors were installed across these pads the capacitors would be
connected in "PARALLEL" with component EP6921 and EP6922(S Bead)
respectvely defeating the purpose of the S Bead functionality.
Personally I feel that these elongated solder pads were not designed
to house the rumored missing capacitors and that the robot did not
forgot to install the rumored capacitors. A robot only does as
instructed(programmed, they do not forget or think for themselves.
There is my two cents worth.

Peter,

Thanks for the additional information. I thought this created a problem
with the 703's internal keyer, which would seem to affect more people.

I guess the issue is that there appears to be quite a bit of evidence of
missing components from these units which solve the keying problems people
are having. As this is obviously an Icom error, it would fall under
warranty repair for those who would wanted to take advantage of it. I
brought up the point as I wasn't sure the key grounding work-around, while
it is effective, is the best solution for optimal performance of the rig (or
possibly even harm) as these "missing" components were designed into the rig
for some reason as opposed to a key ground. I don't have the electronic
expertise to determine whether this is the case or not, but just bring it
up.

I would also be nice to have an indication from Icom (starting serial
numbers) as to when (or if) the robot programming error was fixed.

From all indications, this appear to be a great rig and I look forward to
getting one.

73, Woody AB0ZM

Woody,

I got a photo directly from ICOM after I contacted them at the German Ham
Radio. There are also two missing caps at the processor socket, but
because
there is some shielding above I didn add them (no time, too much work).



The reason that they donÂ’t spread out this info seems clear to me. How
many
of IC703 owners realy use an external keyer?

I have removed the CW problem and replaced it with a power supply
column.http://kn5l.net/ic703/

The CW hang column was not very interesting because it is dependent on
the antenna configuration. If there is RF current on the transmission
line, then the 703 will hang in CW mode. If there is no RF on the
transmission line, then it will work OK. So statistically, all the CW
hang column did was rate our antennas. We will need to wait until we see
some tangible evidence that Icom has fixed something. Meanwhile, don't
let the CW hang problem keep you from acquiring a 703, the problem can
be solved in several ways.

Now the Xmtr section failure is a different issue. So far, I have not
seen any reports about a fixed unit failing again. But it sure would be
nice if we really understood what the problem really is so that we can
preform a preemptive fix.

Hi all,

Now that we know that there are at least two different versions of the 703 in circulation, I wonder if there are any other variations?

My European version - which includes 50MHz, as I believe they all do - also had a TXCO and DSP filter unit fitted as standard. Is this also the case for US versions?

And don't forget to take a look at www.hb9drv.ch for the award-winning Ham Radio Deluxe FREEWARE package: CAT control, PSK31 and Mapping. PLUS! Sat tracking and voice scheduling and speech alarms.

Dietmar,

Very good. That's just what I was wondering about. Certainly one doesn't
want to fix something that already works. But, thought it might be good to
know whether or not you'd confirmed a keying problem before installing the
strap. This workaround certainly seems to work and I don't know that it's
much of an issue having the missing capacitors from the circuit. I just get
an uneasy feeling having design components missing from my rig, not knowing
what other effects if might have on rig performance. Maybe not much in this
case.

The version 18 appears to be for the 703HF and the version 15 for
the 703HF+. Both are the versions are sold here in the US.

From the data available the version 15 703HF+ models seem to have
not experienced output power failures that the version 18 703HF only
have experienced. I sent back my 703HF only after it failed and
requested a 703HF+ as a replacement from AES. Should be here the
beginning of next week.

Good luck,

Maybe I am missing something here BUT how do we know there has been
an error made by Icom in not soldering a capacitor on a
pcb ? Has there been any confirmation from Icom that the assembly
equipment mistakenly left off a capacitor ?

I have been working on electronic equipment for thirty years ,
medical imaging equipment mostly, and it is not unusual to find pcb's
with traces on the board where a component could have been installed
and there was not one installed because the design was
changed before going into production . This usually occurrs when
during the design process , the circuit is still being engineered
or tested while at the same time someone else is working on designing
the actual circuit board . Then before the unit goes into
production the circuit design team decides that some given component
is not needed or that it could be left out with out causing a
problem . So the component is left off but there is no need to
redesign the circuit board to leave off the solder pads . Thus the
missing component is not due to an error in production but due to
the process of taking the design to production. ( where the error
may have been in deciding that the component could be left off , but
not an error in production as sent to the assembly robots )


That being said , it could be that the component was origninally in
the circuit design following some standard engineering practice
from a cook book of designs . Then later as the design is moved
toward production a decision is made to leave the component out of
the produced design . This can happen due to several reasons .
Perhaps it was left off simply because a decision was made that it
could be left out without it causing a problem , or at least their
testing showed it would work fine 98% of the time with out it .
Companies always look for ways to limit component count to hold down
the cost of production . Or perhaps testing showed that to
include it as originally designed caused some other problem . Or
there could be other reasons , maybe their testing showed that
particular component ( as stocked in thier warehouse ) to have a
high failure rate or as designed they could not get the value of
capacitor they wanted or a multitude of other reasons . Even simple
designs become expensive if an attempt is made to make them
100% reliable . So I guess my point is that there may not be an error
due to sloppiness of production but perhaps an error may have
been made in the decision to leave the component out . Or perhaps
not . Ya know the value of capacitor that may cure keying
problems for one ham may not solve the keying problem for another .
Icom certainly has no control over the metod of grounding of
keys used by the many hams who might use their design . They
probably used good engineering practice with the grounding of their
keys during their test and the problem just never happened to them
during their testing .

OTOH - on equipment I have worked on I have also seen pcbs turn up
the other way round on designs of long production life , ie the
early units had all the component holes filed and on later production
runs certain components have been left off the board with no
apparent ill effects . Experience with the design having shown the
part added nothing to proper function and only added to cost of
production .

You may still be able to make a case for warranty repair . Or maybe
not . I suppose it depends upon how wide spread the problem is
or on how well a single fix works for everyone .

David,

You're right. Any of the scenarios you've laid out are possible. The
original post on this issue indicated that an Icom technician confirmed
leaving two capacitors out of the PCB's assembly instructions. This was
related as an error rather than an intentional decision. Following posts
indicated units were returned for warranty repair which included the
installation of the missing capacitors. Information was also posted that
two capacitors were found installed on a unit which were not included on the
unit's schematic causing the possibly of discrepancy between PCB and circuit
design you mentioned. That's a short summary of information to date. The
comment was then added that if the information is correct and an error on
Icom's part, the fix would fall under warranty repair.

I am considering buying a 703+, but would like some details on how
it works on PSK31. I have checked the owners' manual and did not
find it very helpful.

1. What is the best way to interface the computer and the rig? It
looks to me like it should be possible to do through the ACC socket
on the back. Am I right? Can this be done directly, or is it best
to use an interface? Is there a ready made cable to get the right
signals out?

2. It seems to me that I might well want to use an optional CW
filter on PSK31. Again, the manual is not at all helpful on whether
this will work. But it looks to me like one could install a CW
filter, but program the reciver to think its an SSB filter. I'm
probably missing something important, so any thoughts would be
appreciated.

TIA

Jim,

I run PSK31 on my IC703, it is my favorite mode while camped...

I bought a RIGBLASTER when I first got into PSK31 and I have often thougth
of selling it, but I kinda keep it around so I can get "foreign rigs" on PSK
quickly... but Icom has this WONDERFUL 13 pin "mini? DIN" connection on the
back of the radio that has ALL the needed connections in one easy to access
place. By "foreign radios" I mean foreign to me... borrowed, loaned, club,
or something that I ain't had to time to made a interface for.

I just make connection to the 13 pin DIN, and then bring those connections
out to my laptop sound card and RS232 port.

You can find all the details on K6XX's page. While he had the FT-817 in
mind, it follows to the IC-703 quite nicely.
http://www.k6xx.com/ikanrite.html

I do not use optoisolators, so I do not have a BLOB in the middle of the
cable... I put a 2n2222 (good old GP NPN - HFE about 150 or so... nothing
spectacular) inside the DB9 hood, audio/control lines are a shielded piece
of Telco "silver satin" wire... NOT EXACTLY COMMON stuff, but I had a spool
left over from my Telco days... CAT5 would work too.

from the 13 pin DIN to the DB9. Inside the DB9 hood are all my connections,
two audio pairs leave the DB9 hood and go to the sound card.

Software... I use Ham Radio Deluxe to control the radio. HRD has PSK Deluxe
in the "suite"... HRD is FREEWARE from Simon Brown HB9DRV
http://www.kns.ch/sysgem/hb9drv/index.htm

The CAT/CI-V cable is a Yaesu CT- what ever... made for the FT-50, but a
made an adapter that takes the FT-50 connector and converts/adapts to the
IC-703 and my IC-706mk2g... one CI-V cable for the IC-703/706 AND FT-50...
kinda slick to know I did not have to buy yet another accessory.

I called ICOM AMERICA yesterday about the keyer problem and the 60 meter
mod. The customer service representative immediately said to send the 703
in for warranty repair when I said the keyer did not work correctly. When I
asked about the 60 meter mod he said an email to ICOM would get description
of the mod sent out. He also said the ICOM would do the mod when I sent the
unit in for repair of the keyer problem. I told him of the ICOM703 data
base and the reports on over 390 of the 18XXXX series radios on this
newsgroup. He he said he was going to Yahoo site as we spoke.

I did not get a chance to complain about the "ULTIMATe" QRP rig not working
when close to its antenna as is common in field use.


This experience was in sharp contrast to my experience when I called and
emaild ICOM AMERICA about the same problems in May and June after I
purchased the 18 series 703. At that time I was told the keyer problem was
due to not having the rig properly grounded. Regarding the 60M band
allocation, ICOM AMERICA stated it was not repsonsible for band changes made
after the radio was designed. My questions about whether the 703 had been
designed for MARS/CAP mods, as were other ICOM HF radios, went unanswered.

Does removing the keyer problem for the data base indicate that all the
18XXXX series units have the problem?

The problem with having a files section is the ease in which it can be
abused, probably unintentional. While we would not consider taking an
ARRL publication, copying it, and providing it to the masses, it is very
easy to move a Copyrighted document from the ARRL members only area to
another web site. Example, I find that "Swedish Radio Supply"
http://ham.srsab.se/ has a copy of the IC-703 expanded report on their
web pages. Rather disappointing that a commercial enterprise so easily
disregards ARRL's copyrighted material.

The wild west days of the WWW needs to come to an and. This posting is
just a reminder to all to watch what you do and think before posting
other people's materials.

Sorry everyone, my soapbox.

Fellow Amateur Radio Operators:

It would be wise for Icom to be customer friendly. Building a good
relationship with customers is free advertisement for Icom. Good service relations
travels to other Ham's by word of mouth.
Happy customers make good customers and brand loyalty. Stand behind your
products and fix the problems.
I did own another QRP radio. Got cold feet and traded an excellent working
radio.
Reasons for trading were the following:
1. Worried that my finals may someday blow.
2. As I got older I need bifocal glasses and it is harder to read a small
screen.
3. No legs on the radio to make it sit up on a shelf.
4. Problems of other hams getting there radios repaired. ( I wanted good
service and I hope Icom will deliver that service)
Though I did enjoy my previous QRP radio a lot. Maybe when and if they get
the problems fixed, I will buy another one of those QRP radios.
Currently I am waiting for my Icom 703+ radio. It has been sent but has not
arrived yet. I am being patient. I know that we do not live in a perfect world.

Twenty years ago I called Icom's (now defunct) Dallas service center
about an intermittent problem with my (way out of warranty) IC-730 HF
mobile rig thinking I needed to send it in for repair. Rather than
telling me to box it up, the service tech asked if I was comfortable
with taking the covers off and trying a few things. He cheerfully
spent 20 minutes talking me through a troubleshooting routine that
found and fixed the problem (loose ground on one of the RF boards).
I've been a pretty loyal Icom customer since then. Fortunately, I
haven't had to deal with their service department very much since
then, but when I have, they've always done a good job -- perhaps not
as freakishly cooperative as in that 1983 example, but pretty darn
good. For that matter, I've gotten pretty good service from all the
'Big Three'.

I've heard horror stories about service from all of the radio
manufacturers (except Ten Tec), but I suspect customer attitude plays
a part in that. I suppose it's natural to be angry when something
breaks, but what do you want the most -- do you want to punish the
poor guy who picks up the phone at the service department, or do you
want your rig fixed quickly? The service tech probably didn't cause
the radio to fail, so being reasonable may help you get better
service.

I must say that the service provided by Martin Lynch when my 703's drivers

Come to think of it, I have NEVER had a bad experience from any dealer if

Hi!

Here is the data on the 703 I currently have:

S/N: 1501167
Owner: WD9EWK
HF/50 MHz?: Yes
HF/50 MHz faceplate: Yes
Driver failure: No
Keyer problem: Yes, but haven't done the fix yet
Purchased: 26 July 2003
Dealer: HRO/Phoenix AZ, at hamfest in Flagstaff AZ
Power Supply: 12V SLAs, various 13.8V power supplies

For what it's worth, before I bought the HF/6m version, I had
the HF-only 703 for about 2.5 months, and then promptly sold
it at that hamfest when I bought my HF/6m 703 (helped ease the
cash flow). I have not heard from the ham who bought the HF-
only 703 since shortly after that hamfest, but I have some of
its details here:

S/N: 1801120
Owner: WD9EWK, initially (I don't have the details on the ham
who bought this from me - that's at home, I'm not there
at the moment)
HF/50 MHz?: No, HF only
HF/50 MHz faceplate: Yes
Driver failure: No, not as of 26 July 2003
Keyer problem: Yes, but I hadn't done the fix before I sold it
Purchased: 5 May 2003
Dealer: HRO/Phoenix AZ
Power Supply: 12V SLAs, various 13.8V power supplies

I had used the HF-only 703 from home and in the field for the
ARRL Field Day in June. Great radio! Unfortunately, I have
not had enough free time to take the HF/6m 703 out and give it
a workout in the field. I have used it from home, and - so
far - can't complain about it. I'll probably do the keyer fix
myself, rather than ship it back to Icom to deal with.

73!

I did it!

I've been thinking about it for weeks now. On a
whim, I did some price comparisons this afternoon.
R & L Electronics has the IC-703 (not the Plus) on
sale for $569.95 (includes a $60.00 Icom coupon).
That's $40.00 cheaper than anyone else! I couldn't
resist... I gave in bought myself an early Christmas
present!

Next purchase... the 500 Hz CW filter. Any good?

Congratulations!!!!!!

A CW filter is a must if you are going to do CW operating. I have the
Icom 500 Hz, works great. My opinion, the 250 Hz is too narrow.

Yep. Wouldn't consider a rig without some kind of filter for anything
but the most casual CW operation.

In addition to the Icom 500 and 250 hz filters, I understand Inrad
sells 400 and 250 hz versions as well. They're probably about the
same price. The 500 hz filter works fine for me, as the others are a
bit too narrow for my taste. Be careful when ordering -- they're not
the same filters that the '706 uses. They're the solder-in variety,
so choose wisely. You won't want to be swapping them out frequently.

OK Woody , at your suggestion here is the data on my radio .


S/N 1801146
IC703 HF
Drive Failure = NO
Purchased = May '03 at Dayton Hamvention
Owner = WO8W
Face plate says HF/50MHz = YES ( but it is an HF only radio )
Dealer = HRO
Keyer problem = Not yet
power supply : 12vdc ni-cad battery pack , lately a 13.8vdc TenTec
power supply ( as for an Argo V )

Much as I hate to admit it , I have used this radio very little. An
active ham op would have probably used this radio more in one week
than I have in the seven months I have had it . ( my excuse - I' m
just now trying to return to ham radio after ten years off the air ,
just
to busy- unfortunately though I have the desire to get on the air I
find I am still just to busy with other things ) The point I am
trying to
make is that I seem to have a radio which ought to be having the
keyer/driver problems reported by many . I may not have had the
problems simply because I have not had much time to use it , at
least for transmitting . It seems like a wonderful radio but I have
used it more for listening while trying to learn my way around the
menus and how to store freq. in the memory etc than actually
transmitting .

FWIW - The box my radio came in has this information on the sticker :
4909723114362
IC-703
#18 OTH1
1801146

On an previous post I saw a link to http://www.ic
om.co.jp/world/info/ic-703/Version_List.html
and someone wondered what the OTH1 meant . I do not know what it
means either - but it is printed on the shipping box my radio
came in .

Oh, before you install the filter, test to see if you have the dreaded
RF-in-the-keying-circuit problem. If you do and want to fix it
yourself, consider making the key jack grounding modification while
you have the hood open and the iron hot for the filter install. The
mod is trivial compared to the filter installation exercise.

Hans,

You can just plug the supply into the 230 V outlet with
no changes. I have a small switching supply that runs
on 100 - 240 V. It was made to power a laptop computer.
On a trip to Sweden earlier this year, I just bought a
Swedish power cord and plugged it in. No problems. The
charger for my digital camera also worked fine. I just
needed an adaptor for the plug, since it was not the
correct style to fit the Swedish outlet. It seems that
many switching power supplies are made to run on a wide
range of input voltages so that the same model can be
sold all over the world.

Hello all,



I tried both, the Icom 500Hz and the INRAD 400 Hz. Normaly I tend to use
broader filter, but in this cas I decided to stay with the 400 Hz filter
because it is broad enough to seek stations but it excellent shape factor
gives a much better performance then the original 500 Hz

The posting of the TX failure during PSK31 operation at 8 watts got
me thinking. This digital mode of operation, phase-shift keying,
places a burden on the transmitters PA driver and the PA's due to the
fact that the RF carrier is on 100% of the time during transmission.

So I conducted an experiment. I operated my 703+ in RTTY mode at 5
watts with a key down period of 3 minutes. Then I touched the PA
driver transistor Q150 and to my surprise it was quite hot. Heat is
the devil for semiconductor failure. I did not want to take the
chance and increase the power to 8 watts for fear of overheating Q150.
All the postings of the 703 TX failure that I have come across are as
a result of Q150 failing rather then the final PA's.

With that in mind, I installed a heat sink to my Q150 and while I was
at it anyway to the two final PA transistors Q200 and Q201. I won't
go into the details but it was a bear to install the sinks and
requires thermal conductive epoxy (I got from work) to stick the
sinks to the top of the devices in question. I repeated the above
experiment but this time the key down period was 6 minutes and Q150
just was warm to the touch. A big reduction in the temperature and
for the best.

I also own an IC-746PRO which has a much higher report of TX driver
failure(about 15%) that I also modified to keep to keep that driver
PA cooler. Only time will tell if these modifications prologs the
live of my radios but as for mow I do have better peace of mind.

Hi,

I can transmit fine with the microphone, but when I connect an interface (which I know works) to the Data port at the back I can switch the rig to TX but I just cannot get the 703 to put out any signal. It's as if a wire has come off the Data port inside (I can open her up later).

Interestingly if I put too much audio in I am overdriving something inside because a relay starts flipping on an off and then I start getting output.

My FT-817 (same pins) is OK with two different interfaces. Both rigs have the same wiring.

Now am I being dense - can anyone thing of something?

Is it time for the Funny Farm?

Now that I think about it my initial transmitter failure happened
while I was running PSK31 at 6 watts. I finished the message to the
station that I was working and he replied that I had a strong signal
at the beginning and gradually tapered down to nothing. Now I'm no
speed demon when I type (I'm up to using four fingers now) so I can
imagine the PA driver was being heavily taxed during the QSO.

Good point Dietmar.

If you want to be sure of having a clean TX signal you shouldn't drive the

Mine actually failed during an SSB QSO - the other guy pointed out that my
signal was distorting badly then faded to almost nothing. But he was still
hearing me with what later turned out to be 20mW SSB on 40 - over about 300

Does anyone have some experience running a balanced antenna, such as a Zepp or "flat top?" with the IC-703+ and its internal tuner? This looks problematic since the internal tuner seems to be designed for "coax to coax" applications, and I'm told, has a reputation for having a limited tuning range.

If you've used an external tuner, which one and why?

What I have in mind is using the -703 as a dedicated PSK31 radio in the shack, when I'm not using it in the field. That means I could conceivably tune the antenna once on either the 80 or 20 Mtr PSK frequency, or perhaps, the NJQRP "Warbler" frequency.

BTW, I believe the "Warbler" frequency is actually the TV "colorburst" frequency. Does this pose a problem for indoor operation?

Hi Frank,

I have used the internal tuner with my antenna that is feed with 300
ohm twin line. The setup used an old heathkit balun box between the
antenna and the IC-703. While it worked on the higher bands, with my
antenna I had problem tuning up on some parts of the lower bands.

The final solution was to go with an ICOM AH-4 auto tuner (after a bad
experience with an SGC auto tuner). The AH-4 is well worth the price!
With my antenna I have no problems tuning up on any frequency 160 - 6
meters. I have the IC-703 set for PTT tune so that any time I go to
transmit and the match is not satisfactory, the rig automatically
tunes the AH-4.. Truly automatic this way, you don't even have to
think about the tuner, you are really spoiled with this setup.

The antenna is a dipole cut to aprox. 67.5 feet per side, fed with 300
ohm TV twinlead. It is up near 30ft. in the center and 10ft. on the
ends.

Hello Frank,

because I only use antennas with balanced feeds I had the same issue with
the K2 and its internal tuner. So I designed a "plugin Balun" some time
agao. I use the same design for the IC703 internal tuner now. The 4:1 ratio
helps a little bit because the range of the tuner is very low.

It is a 1:4 guanelly type an 2 Amidon FT80/43. You find a description and
some fotos on my homepage at

http://www.werdau.net/qrpproject/k2_k1_balun.htm

You will see a VSWR vs frequency chart there. It shows a typical VSWR wihis
is speciefied by me as better 1,1 between 1 MHz and 50 MHz.

Hi all,

The award-winning Ham Radio Deluxe Development Team are pleased to announce the release of Ham Radio Deluxe v1.1.

HAM RADIO DELUXE IS FREEWARE.

For those who didn't know it already, Ham Radio Deluxe is the logical evolution of the immensely popular and groundbreaking FT-817 Commander program. Unfortunately the FT-817 Commander was only capable of controlling Yaesu's FT-817, and there was a clear requirement for a CAT program with comprehensive support for various rigs. This led to development of Ham Radio Deluxe being started in early June 2003, since when the program has been rapidly evolving.

Ham Radio Deluxe does not make the mistake of trying to look like a traditional radio with rotary knobs and buttons. The GUI is more reminiscent of an old Eddystone receiver, with clearly marked buttons for switching modes, filters and other functions. Some - but not all - rigs also support sliders, which can be displayed or hidden as preferred, to control volume, IF shift, RF gain &c. The GUI is fully user-configurable with respect to colours, fonts and band indicators: this offers the user an unprecedented level of customisation. Because the program is so simple and logical to use, no documentation is required other than the rig's user manual.

Included in the package are PSK31Deluxe and Mapper.

PSK31 Deluxe is a very sophisticated PSK31 program based on Moe Wheatly's PSKCORE.DLL. It has two main guises: a traditional QSO window type of user interface, and the revolutionary SuperBrowser - SuperBrowser allows you to monitor up to 40 QSO channels at one time while conducting a QSO. PSK31 Deluxe offers comprehensive user-defined macros and tags, and of course the GUI is fully user-configurable.

Some of the more interesting features are:

The unique SuperBrowser.
Centring of the desired signal in the filter's passband.
'Click and insert' of your QSO partner's information into tags and macros (callsign, name, QTH &c)
TX frequency shift for soundcards with differences between RX and TX frequency.
A fully customisable waterfall display.



MAPPER:

Mapper is - the name says it all - an amateur radio mapping program. It is capable of printing customisable maps of up to 10 x 10 sheets of paper, but its main function is the capture and display of Maidenhead locator information from PSK31 Deluxe. Beam heading and distance can also be displayed, and for the QRP ops among us there is also a 'miles per watt' calculator. Just place your mouse pointer on the relevant spot on the map and read off the MPW.


RIG SUPPORT:

At the time of writing (4 December) the following rigs were supported:

I am really looking forward to seeing your response. I am currently
debating between an IC-703 and an Argonaut V. I very much like the
receiver specs. on the 703 and would probably go with it if were not
that I feel like I'll be rolling the dice on getting a "good" one or
a "bad" one. It's bad enough that I may have to go through the
hassle of getting it repaired, but if the 7003 has problems that
Icom is not even willing to own up to, well that's important to know.

Tnx.

I agree with you 100%

I'm a member of the ARRL for many reasons and don't appreciate folks sending out the publications we
pay for

the investment requirement
needed in radios alone.

jim and all...

I have both.. the argonaut V and the 703..

my 703 was purchased at dayton 2003
lasted until june and then died..

trouble keying cw with anything but an large outside antenna. called icom
tech help and got the run around.

got the problem fixed by jumping the key jack to ground.. but it's still not
perfect.

the argonaut V wins hand down when it comes to service..

the icom guy told me "there have been no reports of keying problems with the
703"

after i emailed the guy the fix I had, he said he would "pass it along to
tech support"

Hi Frank..

You can use either the AH-4 or the internal tuner, only one at a time
When the AH-4 is plugged in, the internal tuner is disabled.

My comments about using the internal tuner with a balun refer to my
experience before getting the AH-4.

Hello Everyone,

Received the replacement IC703 from AES yesterday evening. I paid
the difference and had the IC703 HF only replaced with the IC703

huge potential providing Icom can get the bugs worked out. The

Bob K8YS
| 770|768|2003-12-15 22:54:55|linux_author|Re: Should I buy?|
1. perhaps it depends on how many rigs do you have? i have an FT-817
w/Norcal BLT tuner for portable/airline travel, FT-897 w/LDG AT11MP
tuner for base/portable/vacation travel, FT-857 for mobile, and a
TS-570DG for base... in my case, i found a used 703 (HF only) for
US$400+change at the local candy store, so i figured 'what the
heck'... if it breaks, ICOM will fix it, and i won't be left without a
portable... plus, the XYL lets me buy whatever i want...

:-)

2. as an alternative QRP rig, the FT-817 is not without its problems
(and detractors)... if its finals go, i have a spare board (acquired
for US$35) waiting in the box when needed for repair... the FT-817 is
a good deal right now, as after rebate it is US$469... i really like
the 817, and have had many great QSOs w/it...

3. but i like the 703 and think it's a great little rig... it feels
'comfortable' to use, and i really like the button layout, large LCD,
and VFO... i've found the tuner to work well for me... i use a 17M
Lakeview hamstick in a mount w/a clamp for a portable antenna, and the
703 works across 17M and tunes across 20M on the same hamstick...

4. considering the 703 has the built-in tuner and DSP, i think it's a
good deal... it's not DC-to-daylight, but its NB and DSP work great...

5. on the downside, ICOM makes you bend over and grab your ankles on
accessories; but the 703 can use nearly all 706MIIG goodies... i think
they could have included a carry handle, but since they didn't, i
tooled and attached a custom leather handle (which looks better,
IMHO)... the prices for the ICOM filters are outrageous, but Inrad has
stepped up to the plate w/somewhat cheaper alternatives...

so i guess i'm asking, "What role will the rig play in your operating
plans?" ... i plan to take my 703 with me as a backup QRP rig while
vacationing via car or when operating QRP in a local park; the 817
goes w/me when traveling via air... but i won't have to depend on the
703 as a primary mobile HF or base rig...

i wouldn't worry about reliability of any rig from any manufacturer...
all amateur radio transceivers on the market today are designed to be
fairly 'robust'... can you hurt a rig? sure! do some manufacturing
runs have problems? sure! does it sometimes pay to wait until a model
has been out on the market for a while? well, maybe and maybe not...
even commercial radios have problems...

if a rig breaks, get it fixed... just enjoy its features, get on the
air, and have fun!

after all, this is a hobby!

:-)

hope this helps,

bill, kg4zqz

Hi Roger,

Buy from a reputable source - I bought from Chris Taylor at Martin Lynch.
This is an excellent QRP rig, the RX a true beauty. You have one potential
problem with the driver going 'phut' but Chris has had Peter PH1PH's rig
repaired and returned to Holland in next to no time.

I also have the FT-817 - for me the IC-703 wins hands down.

I would not hesitate in buying one again.

weeks (including eight days shipping and the Thanksgiving holiday).
Not bad. All the lights come on and it makes power again (no smoke).

Thanks Peter, your data is in the table at http://kn5l.net/ic703/

We now have 31 entries and nine TX failures. A TX failure was reported
over the weekend, but no serial number or other data, so I did not enter
it into the database.

There are 339 members in this group, but only 31 reported radios. There
must be more in this group. Any more out there?

I had my first IC-703 to IC-703 QSO last week! With N8BWU. It was a SSB
contact on 14.240. Normally 14.240 is occupied by a DX group, most
running KW+ and beams, and there Dave and I were, running 10W and both
of us using verticals.

I'm having a problem with my brand new IC-703.
Whenever the rig is in CW mode, the keyer sends
a continuous iambic pattern (didahdidahdidah)
whether I have paddles plugged in or not. This
started right after I installed an InRad 400 Hz
CW filter. Other than the keyer problem, the
rig seems to be working. I've inspected the
entire main board, top and bottom, looking for
errant bits of solder or loose wires, and I've
performed a full reset per the manual. I used
an Ohmmeter to check the resistance from the
paddle jack contacts to ground. The tip reads
about 1.9 Ohms, and the ring reads about 3.4
Ohms. That doesn't seem right to me, but I
can't claim to be a '703 expert (yet!).

Does anyone have any ideas? I emailed Icom last
night and asked them what to do. No response
received yet (they claim a 48 hour turnaround
on email requests; we'll see).

Dean,

According to the schematic the two keying lines, DASK and DOTK, go off
to the processor via a wire bundle. Just before the processor there is
a 1K resistor in series with each of the two keying wires. Looks like
either the key connector or possibly another intermediate connector is
shorted somewhere. Worst case it would look like 1 K to ground.

I have an IC-703 which I bought brand new. I ran a couple of QSOs with it mainly in CW and decided it was not much fun unless I installed a CW filter.

I need to say that I've soldered in a lot of CW filters into rigs in the past more than 30 years of my ham career. So I know how to do it for sure.

As I was heavily travelling on business trips that time I sent the rig in to the shop where I bought it for repair anticipating some other problem with the rig covered by the warranty.

I got it back from the shop with a 150 Euro bill saying that the INRAD filter shortened out some PCB traces causing the radio not to start up.

So far I have not followed up the case. But it looks like that there is an issue with the IC-703 and INRAD filters.
I will follow up on this the next few days and post at Yahoo as soon as I have news.

When my first 703 failed I had the opportunity to get something else
but still went with the 703. This radio has lots of potential and

issues with later production runs.

Klaus, there is an issue with any filter if it is built in without
preserving a little distance between the filterbody and the PCB. This is
also true for most homebrew project using filters, Ringmixers and even
simple xtals. If you press the metall body tight to the board, you may
shorten the PADs

Yes, it should work fine with both radios, but you'll need an 8-pin to
RJ45 modular adapter since the rigs have different microphone jack
types.

Ach, I meant to say that if the headset microphone is the "iC" type,
it'll work well with both rigs.

My IC703 arrived from Water and Stanton yesterday and was unpacked
briefly for a pre-Christmas checking - to keep the XYL sweet I agreed
to put it away again until Christmas! I hope there won't be too much
soot on it from Father Christmas coming down the chimney...

First impressions (on a long wire about 50-60ft long at 15 feet up)
using a central heating radiator as ground:

1. The RX is nicely quiet but sensitive, even without the DSP
switched in. It reminds me of my old FT7 in this respect: that was
the best receiver I'd ever used ansd this one rivals it.

2. DSP filter works nicely. Not having used a heterodyne "remover"
before it was unbelievable how well it worked. The progressive step
DSP noise filter works well too.

3. Dial backlight was a relaxing amber colour. I had expected it to
be a harsh yellow.

4. Menus are easy to follow (although I'd seen these before in an
IC706)

5. ATU - it loaded the longwire on ALL bands except 160m! Much better
than expected. I was surprised how, once stored, the ATU reset to a
band change almost immediately - clatter of relays for a few
milliseconds and it was there.

6. One on the air QSO with an HB9 got an RS55 report with "excellent
audio" on 80m. I have yet to try CW (an to see if the keyer problem
is there or not).

Overall, well pleased so far and roll on Christmas playtime!

My IC-703 is once again working!

I would like to extend a great big Texas-sized "THANK YOU!!!" to all
of the folks who clued me in to the possibility that an InRad CW
filter might short out the traces on the IC-703's main board. That
was exactly what had happened! I pulled the filter last night and
verified that the radio worked properly without it, and when I re-
installed the filter, I used four little nylon washers as spacers to
raise the filter body up off the circuit board, one on each mounting
screw and one on each of the two outer-most solder pins.

I plan to contact InRad and suggest that they include a note with all
IC-703 filters that describes this problem. I also plan to email
Icom's service department and brief them on the problem and
solution. The technician who answered my email claimed that they had
no previous reports of the keyer problem that I described, and the
mention of the InRad filter in my message to them didn't spark any
memories.

Again, thanks a bunch for the help! You guys saved me a lot of
money, because Icom service would have charged me at least one hour
of labor, plus shipping both ways!!!

I emailed George at InRad to tell him about the need to use spacers
underneath their filters. He was very appreciative of the feedback
and he said they will be including some washers for that purpose,

Hi Roger,

I saw your message on the 703 list. Did you mean that the internal tuner tuned your longwire or did you have the external one?

I was also impressed by your comments on the receiver. I am really hard pressed to make a decision between the 703 and the FT-817. really like the idea of portability. I have this fantasy about walking on a trail and stopping to work DX at a scenic overlook. I suppose you can do the same with the 703 but a little heavier.

703 FT-817
Internal Tuner yes no
DSP yes no-extra
weight 4.6 2.6
newer technology yes ...
Screen OK very small
tuning knob OK very small
price difference $140 + $140 -
6 meters extra $79. standard
2/70 NO YES (I have a FT-50R, FM only)
Power 1-10 1-5


Do you have any other thoughts, or can you tell me if you considered the FT-817?

BTW, I love England! I just got back from my 6th trip in November. I plan to return in late April or early May and walk the Hadrian Wall Path from sea to sea. I was palnning on a 817 accompaning me but the 703 has thrown a monkey wrench (spanner) into the works.

Sorry to pick on you but I saw your message and thought new buyer you have been having all these thoughts anyway. BTW, lucky you on your new radio.

73 and Merry Christmas from Louisiana in the southern US.

Hi Dean,

I saw on your web site that you had the FT-817 and you now have the 703. Can you give me a little comparison. I am in the market. I was at first all hip on the 817 because of the very small size and weight. Then I started seeing info on the 703. I assume that you have sold your 817.

Any thoughts you want to give would be appreciated.

John,

I think you'll find that a number of folks have both radios, and
intend to keep them both. I do and I do. I'd probably pick the Icom
if I had to choose one, but hey, I got the '817 three years ago, got a
lot of use out of it, never had a minute's trouble with it, and still
like it for some things. They're both good radios. Each has its
strong points, but you really can't go wrong by choosing one over the
other.

| 801|793|2003-12-18 21:13:42|Thomas Robinson|Re: IC703 - my first impressions|
Hi John and the Group

I have only the 817, however, I did manage to have a loan of a 703 for a
week in August.

I thoroughly enjoyed the rig and wish I could justify the purchase of one.
I believe the pros and cons of 817 V 703 have been discussed at length in
the posts to this Group but I will add my 2 pennyworth.

To me it comes down to assessing if the 2m/70Cms CW and SSB capability is
required and if you are happy with a max 5W; rather than the Icom's10W and
the built in ATU (which I found much better than expected) is a very big
plus for the 703. Given that you already have FM handheld maybe you don't
need the 817's VHF/UHF multimode capability - you will not get many 2m
CW/SSB contacts on Hadrians Wall.

I see you fantasise about having a short stop from your hiking and working
a bit of DX. Why not work a bit of DX while you continue to walk?

I almost did that today but conditions on 17m were poor this afternoon.
Still during a 5 mile walk I managed to work Romania, Russia, Malta, Spain,
Finland and a local English station. The Scenery was not as great as that
along Hadrians wall (some of it was below sea level) but it was great fun.

This was done using an 817 assisted by a Tokyo High Power HL-50B amplifier,
LDG Z11 autotuner, NiMH battery packs and a 13' whip antenna fastened to my
backpack.

Apart from the 50W available to me from the amp the 703 would have done the
same, given me some DSP capability and been a lot more user friendly - good
ergonomics.

Cheers

i have had all major prolems with ic-703. my tx stopped, and I have the keyer problem.
Icom gave me new rig rather than fix the old one. I still have the keyer problem..even after making the
keyer ground mod.

However, the good news is that the INRAD 400 hz filter is superb!.
It's quiet, thick receiver walls, and may well be the best cw filter i have ever used. The receiver on the rig
is very good. I Installed the filter and put just a tiny touch of solder on each leg. The filter is , for all
intents and purposes, not pressed down onto the board. It touches the board only rarely.

After having this radio for around 6 months (give or take) and the yaesu ft-817 for about a year, there is no
question which rig I would sell if i were strapped for cash....The 703.

Icom is going out of there way with the denial thing concerning the obvious problems with the radio. I think that this
is a problem way beyond the relatively "minor" problems which should be resolved when the rig is sent in for
repair. This, and the fact that the yaesu rig, when used with the ldg-11, is a much more well rounded radio.

I did indeed break my 817, but i got 16 day turnaround on it, including shipping time from Birmingham
to CA, or WA and back (i forget, but it's a 5 day hard drive for any trucker...)

I have both radios also. The 703 is a great radio and the menus are
easy to use and the little buttons are backlit so I can see the damn
things. Plus it has the internal tuner. The 817 also a great radio and
is considerably more compact and more ruggedly built, covers more bands,
but has no tuner. The 703 is about two pounds heavier. For backcountry
use: the 817 goes. For qrp at home: I use the 703.

One note: I sort of like the dsp in the 703 but it doesn't work
anywhere near as well as the dsp in an FT-100D. On the other hand,
there is no dsp in the ft-817 although there are add-ons.

Hello All,

A couple of weeks ago I installed (with difficulty) homemade heats to
my 703+ TX driver transistor and to the two PA finals in an effort to
prevent the known TX failure. Today I decided to subject the
transmitter to a daring and bold endurance test to see if my effort
paid off. The transmitter was turned on contiuously for 2 hours in
RTTY mode at 5 watts into a dummy load. The supply voltage was 13.8
volts. The heat sinks got hot, however, you could still leave your
finger on them comfortably. The transmitter did "NOT" fail. I would
not have attempted this test without the benefit of the extra heat
sinks. I thought the group would be interested in the results.

Mine went during a short SSB QSO in which I'd turned the power down to 5W -

drivers fail(ed). Could it be poor soldering, or even a bad batch of
drivers? Since being repaired last June my 703 has had to work a LOT

I'm thinking that there are four kinds of "grab and go radios"
1. The new FT-897: You grab it and go. It has a battery option for
use at a remote location but it's big and heavy.
2. Next is the IC-703: It's not a small radio but it is much
lighter and addresses power consumption better than the HF mobiles.
3. The FT-817: It's small enough to throw in a backpack or fanny
back, has internal battery options and is very light.
4. The real portables: Such as the Tokoyo Hi-Power Tribanders and
all the homebrew kits.

Every step up or down is a compromise.

Peter,

I disagree, with respect to the INRAD filter mounting.

As can be seen from a detailed look at the Icom 703 manual page 87
(English manual) 'IF filter (installation)' there are 2 washers to be
mounted between the FL53A/52A filter and the top surface of the PCB.
I did not pay attention to this when I installed the INRAD filter.

As a matter of fact there are no such washers included in the INRAD
filter package.

The possible result is that the bottom metal part of the INRAD filter
may shorten PCB traces (as in my case).

So, the solution is *not* as you indicated 'preserving a little
distance' by guessing but to include means i.e. parts (washers) to
make this process of installing the filter a re-produceable and
reliable one.

Based on opinions of those members who have the radio + other sources, i will make a decision to buy it or not. I bet half of the registered members don't even have the radio....

I also agree with another poster who suggests sending the data on
serial numbers and failures to ICOM. If they are interested
in "cuddling their customers" (or whatever the buzz phrase is these
days) they will be very grateful for the feedback to help them
overcome the design or process weakness.

Another poster made the point that many here don't yet own the rig. I

- i love all QRP rigs! i started w/the 817, but i also found a nice
703 recently... i'm not worried about *any* rig going tango uniform,
'cause i'll just get it fixed (or fix it myself; i have a spare final
board for my 817 - about $40 shipped)...

- i like the 703... there's no rig on the market like the 817 for
portability, but the 703 fills a nice niche for operating QRP with a
7.5Ah SLA while at a park on the weekend or on vacation (sitting on
the deck, watching the waves break on the beach, etc.)

- IMO, no rig is without flaws or perfect for every operator... my
problem is that i don't know if i like a rig or not unless i've used
it for a few months... this has lead to a very expensive solution: get
one of each!

I'm one of those who doesn't have an IC-703 yet, but one is ordered
and on the way. For my particular needs, the 703 was my first
choice. I was/am concerned about the Tx failure problem, but in the
end I looked at your data and decided there just weren't that many
failure reports to make me go to my "second" choice. Without your
data, I might well have come to a different conclusion -- looking at
the numbers is much more helpful than reading a series of messages.
I think anybody reading your data would realize that radios with no
failures would be very under reported and factor that into their
thinking.

Just one view. And thanks very much for your work in putting the

Hi! To all,
I purchased a IC-703 + in November 2003. The Microprocessor in the head was
not giving the right information to the processor in the body of the radio. The
problem that I had, was the continuos scrolling of the radio frequency and
not stopping even after resetting the CPU of the radio. The Amateur Radio dealer
has taken back the faulty radio and ordered me a new one to be delivered
before Christmas we hope. The faulty radio has been sent back to Icom.
Looking foreword to using my radio.

| 824|824|2003-12-21 05:41:43|Terry Neumann|Failures - What is an acceptable rate??|
It has been noted:


I've seen similar sentiments expressed before, perhaps on this list, perhaps on others. (I see a lot of familiar names on the HFpack, and FT817 groups and it's not uncommon for threads to become interwoven).

I disagree with the sentiment that a certain mathematical failure rate is acceptable.

Failures such as we see reported above would cause letters to the editor of any national newspaper if it were the case in motor vehicles, TV sets, washing machines, or toothbrushes. There would be a public outcry and a recall by the manufacturers. In Australia, there would probably be a Royal Commission or a Senate enquiry.....

What percentage of failure is acceptable for the space programme? For aircraft? What about the devices which operate traffic signals? All use electronic components assembled together to produce a result which anticipates and indeed demands 100% reliability. Should we really have to expect less?

After all the design and manufacture of commercial radios is now a known art. The manufacture of components should be a precise and replicable science. The two should meet, and reliable radios which operate reliably well into the future should be a quite reasonable and confident expectation.

The plaintive cries from manufacturers that there "isn't a problem" is exactly what you would expect (Sadly). What person wanting to retain his/her employment would sacrifice company image and prestige by admitting that "Look - we know there's a problem. We stuffed up and we really don't know what to do about it ..... (Other than fix those that come back for repair under warranty)". Their reaction is quite predictable. Why are we accepting it for other than what it is? - a cover up for poor design and inadequate testing before commercial release.

We amateurs are catering to this deception by making excuses for an unacceptable situation and treating it as though it were the norm. We therefore deserve what we get both now and into the future - that is more of the same.

Bullshit. Anyone who knows anything about real components in any
industry knows 100% reliability isn't possible. This only exists in the
minds of lawyers. The combination of time (schedule), and cost always
contribute to a compromise in design which will always yield a certain
reliability whether or not it is in radio design or automobiles. The
automotive industry has the advantage of many years of experience at
building essentially the same product to the tune of many millions of
units. There is something called MIL-HDBK-217 which is what the US
miliary uses to evaluate the failure rate of designs. At least they are
smart enough to know that stuff fails. There is no way anything can
achieve 100% reliability for infinite time and anyone who expects that
is suffering from a delusion.

The 703 is a very nice radio. It is better than the FT-817 in some
areas. It will work quite well in the hands of most amateurs. I have
both radios and they are in my opinion both terrifiic. I am not afraid
of any failures since I don't expect either of them to last forever. I
expect that when one or the other blows up I will have to fix it, just
as I have to do with my Toyota.

Hello Everyone,

It was a nice day here in south central Iowa with temps in the lower
50's. I decided to try the 703 portable so I took the rig and the MP-
1 Superantenna out to the back yard and gave it a whirl. I powered
the rig from the 12 volt power source in the Taurus.

It ook a bit of effort to get the MP-1 somewhat resonant in order
for the internal tuner to work. Once that was accomplished I managed
to work a couple of east coast stations with 5x7 reports. So being
successful I took everything apart later on and headed out to Red
Haw State Park to try my luck there. Talked to Bonnie KQ6XA and the
HFPack Group from the park. Bonnie told me the signal was weak but
readable.

All in all the 10 watts was doing the job. The 703 performed without
a hitch. I was in a high SWR situation for a short while trying to
get the MP-1 close to resonance and the rig did roll back the power
to about 2 1/2 watts as could be expected. After the first 703
failed I could have gotten a different brand of radio but I really
do like this little rig.

73's to all and a very Merry Christmas.

Looking to swap my near mint 703 (hf only) towards a Yaesu FT897. I have
all the
original factory docs, manual, mic, and box. The radio looks like new,
hasn't
been used more than one hour.

Negotiable accessories are the LC backpack, Heil Traveler and Icom

Concerning Icom IC-703 (European model, that is with 50 Mhz).



The swedish general agent SRS AB guru (Roy) hasnÂ’t heard anything the
problems with the cw function.



He also gave me a clue how to make the ATU work better. If you open up, that
is in military terms makes the radio “green”, to transmit without any
freq-limits, the ATU will function much better and even make longwires work
ok.



He will send me docs about open up in a couple of days.



In Sweden itÂ’s allowed to have a radio in your position that is open up as
long as you are not transmitting on not allowed freqÂ’s. You do not need to
have a amateur licens to buy a radio. A couple of years ago not even the
police had the right to confiscate the radio without having a person that
had such amateur licens with them. A parentes only.

Hi Hans,

It sure odd that booth radios are in the same lot with the same problems.
They either have a quality control problem or bad parts. It would be interesting
to see if other IC-703+ have the same problem in that same lot number. I
wonder how many radios are in a lot? I wish they would continue posting all the
Ic-703's and +'s with problems and also those that don't have problems on Yahoo.
If we would all send are Information in to this web site and pass the word
around to other amateur operators to do the same, maybe things would change. The
Yeasu Ft-817 yahoo web site should also do the same. Then we can tell
prospective IC-703 or Yeasu Ft-817 owners which lot radios to avoid. Then you could
tell the dealers which lot numbers you don't want. The lot numbers are on the
outside of the box. If you receive the bad lot number send it right back to the
dealer or Icom. The dealers and Icom will soon or later get the message that
we are not willing to waste our time with bad equipment.

Maybe it is time to get back to American made radios (Ten-tec QRP radio or
Elecraft K2) they seem to not be having problems.
Usually Japan made electronic equipment that was quality. This is not normal.

Have a great Holiday, Merry Christmas & Happy New Year and Ham it up.

I think the Yahoo! '817 group has been polling its membership in an
attempt to discover which lots are having the most problems with
failing finals (a problem similar in effect and frequency to the 703's

| 835|835|2003-12-23 19:26:28|marky|Re: Digest Number 199|
the BIGGEST difference, to me, in the ICOM 703 and the Yaesu 817 (i own both
and had finals let go in both) is customer service.

I sent my 703 into Icom and after 3 weeks they had not even looked at it.
After I griped, they sent a new one to me. About a 5 week wait. I sent my
817 in and received it back at my home in 16 days better than new.

My 817 works so well that I continue to use it almost daily. The 703 only
does one thing well - listen. Being a cw op, it's simply not a useable
radio if I want to transmit with it.

In nearly 20 years of being a ham and breaking radios, I can say one thing
as fact. Yaesu values their customers. Their repair technicians seem to
actually enjoy their jobs. That being said, I look forward to
operating my new ft-857 this holiday season.

Icom's failure to acknowledge several problems is what is making people
hostile, not the failure of their product. And THAT is a management
problem, not a technical issue.

More information needed:

Or, it does not have the optimal relayless QSK? Does having a relay QSK
transceiver make it "useable?" I pick this issue because it is the only
issue that I can think of that would cause someone to make such a
profound statement as "it's simply not a useable radio if I want to
transmit with it."

My 703 has worked flawlessly from my first QSO on October 9th to now
with 80 Qs in my logbook. Mostly CW, estimate 10% SSB. All reported
signal reports are complimentary, which we should expect from CW
reports. I get rather nice comments about the SSB audio.

I am not a big QSK user and almost never use it during rag chews. I do,
in fact, like a foot switch to keep the transmitter keyed during the
full transmission because the switch over interrupts my thoughts while
sending. On the other hand, I do some CW contesting, where QSK is a
must. I have use my old IC-738, with relay QSK, for years during many CW
contests. It makes a little noise.

This is not a pro or con 817 or 703. Select your favorite based on the
different feature set. I picked the 703 first for the internal antenna
tuner, which by the way works much better than the very conservative
Icom specifications. The extra output power was my second. I'll confess,
also selected the 703 because it was a new radio on the market. Lower on
my selection criteria is the DSP. I did not need an internal battery
because I want to tune my battery for usage, at this time I'm using a 7
AH SLA to get extended operating time at maximum power. I do not need
VHF or UHF. No backpacking for me, I would rather have the larger
display and controls.

By the way I have had mine since August when I started on HF. Can't
say a bad word about it. Its intuitive to use, full of useful, but
not too complicated features and gets regular comments on the great
audio and signal. Add to that it seems to tune a wet piece of string
(O.K I'm going too far now !) and all in all a great package.

Hello: I am brand new to this group. I have been reading the ICOM 703 and + reviews and they sound good. But after reading the mail I am not so sure. I am interested in the 703+ and I do alot of CW. I would like to hear from people who own the 703+ and do CW and also use it with an antenna like a G5RV. I dont want to spend the money if this rig is going blow its output finals and have problems on CW. Any and all responses will be appreciated.

Hi Mark,

Here's my 2 cents. My first 703 HF only lasted four days befoe the
output power went south. I bought the rig knowing that this could
happen and if I did I would send it back. I could have gotten a
different brand of rig as a replacement but requested the 703 plus
model for an aditional eighty bucks as the replacement.

Why you ask? I simply like the concept of the 703 series and if this
one goes south I'll replace it or get it repaired. If we all made
our decisions from the internet reviews on whatever product or
service we might be considering we would buy nothing out of fear of
a failure of some kind.

As far as CW with the 703, I use only a straight key so I haven't
experienced what some of the other folks have experienced in regard
to CW. I'm not a dedicated CW op but the little rig seems to do a
good job in that respect.

Good luck with your choice either way.

I've own two 703's so far ... Biggest CW problem I see is that if you do
a lot of CW, the 500hz filter is a MUST!
My complaint on this is Icom put in DSP for SSB, but not for CW...how
hard would it have been to program a narrrow DSP when in CW?... they
make you buy a filter for 1/4 the radio cost!!

As to the 703's, both went south in less than two weeks. I'm waiting
till the bugs are out.

========

Just playing with a new Icom 703....( A PDF manual is d/l'able from
Icom America. )


I like it!
It's bigger than the 817, just a bit smaller than the K2.

Battery draw @14v dc is 580 ma (1/3 volume with some signal). 605 ma
with preamp on.....
The powersaving features include display backlight (hi,lo,off),
buttons light (ho,lo,off), led lights (hi,lo), a sort of power saving
sleep mode and the auto off.
This leads up to about 380 ma draw on rx for me... it was listed as
250 ma? min somewhere, but that's prob with the sleep mode on - in
standby.
Anyway, not bad for the rig with this features.

Turner works just fine on my vertical and on some wire antennas. It
seems to tune a bit over the 3:1 swr range and if it doesn't tune ,the
tuner just turns off quickly. Speed of the turner is on par with the
K2 and LDG tuners. The tuner has memories for the different bands, but
I couldn't find the total number of memories it will retain.

The Setting for output power out is relative, not direct readout... it
puts out (on my Oak Hill meter) from 100 mw (bottom of L) to 10w (on
H).... 5w out is aprox 7 on the output scale ( though power out does
vary in same readout number slightly depending how far in the rotation
you are to the next digit)

SSB band and CW reports have all been good on stock settings, so no
change there yet.
There is plenty of audio and speaker quality is good.

The DSP for noise works fine on SSB with the auto notch filter working
great too. Sorry to say there is no DSP narrow filter for CW and for
heavy CW ops, this radio will need a filter (read $169 option).

CW is set for Off, Break-in (setable hang) and Full Bkin... in Full
there is some relay chatter, not really loud, but it's there.


Results;

Likes:
Antenna tuner built in
keyer memory and contest counter
LARGER buttons/display for these fat fingers and getting old eyes
10 watts

Dislikes:
1/4 phone plug for the keyer (a jack on the front would be nice)
In full break-in, relay makes a little noise
No tight DSP filter for CW (rig needs 500 filter for real cw use)


All best
Tom aa2vk

5/17/03
========

I started getting into the power savers of the 703

Normal draw is about 580ma with preamp off 1/3 volume; settings at
default and 14v supply.

For the display Back light:
From High to Low, 40 ma... from L to Off, 45 ma for a total of about
100 ma savings if you turn off the display lighting.

Button Lights:
From High to Low, 20 ma ... from L to off 30ma fo a total of about 50
ma savings.

So just from turning off the display and button lights you can save
150 ma!

Turn the LEDS from H to L and save another 40ma

Total drop about 200ma!!

As previous stated, I've had my down to 380ma or so .... I'm still
trying to break that 300ma mark.
Will test the sleep mode soon.

all best

Needing a CW filter is a reality, not a problem. The IC-703 uses
mechanical filters for bandwidth limiting. It comes with a 2.4 KHz SSB
filter and space for one optional filter. The reality is that mechanical
filters are expensive. A CW filter does make CW much more enjoyable to
use.

Sorry, just not a valid complaint because: The IC-703 does not use DSP
for establishing bandwidth. The DSP is used for noise reduction for both
CW and SSB and for filtering out CW signals in SSB mode.

Read the DSP description at
http://www.icom.co.jp/world/products/amateur/703/

"DSP capabilities give you tools to reduce interfering signals, or just
to dig weak signals out of the dirt. The noise reduction separates
desired signals from noise and reduces the noise components for a
clearer received signal, while the auto notch tracks and eliminates
interference from a solid tone signal."

There are radio's on the market that use DSP for bandwidth limiting, the
IC-703 just isn't one of them.

Yep. The cw filter is about mandatory for cw work. The Icom dsp is
also kinda inferior, especially compared to the FT-100D which has a nice
bandpass dsp function which is very handy on cw. On the other hand, the
FT-817 doesn't have any dsp. I also find the Icom dsp to be annoyingly
biased towards ssb use.

I wonder, being a 703 owner, just what make the 703 DSP biased towards

The 703 has the ability to have two filters to set the receiver
bandwidth. One is fixed to 2.4 KHz (normal SSB) and a socket for a
optional filter which can be either CW or SSB filter of your choice from
a few options. This is a very normal configuration, including some Yaesu
radios.

Don't make the 703 DSP something that it is not. It has no bandwidth,
bandpass, or skirt selection capability. The 703 DSP is only used for
noise reduction and an auto notch filter. The noise reduction works
equally well for both CW and SSB. It would be rather silly to enable
auto notch while in CW mode, so it is disabled.

| 852|839|2003-12-24 20:39:53|Rick Booth|Re: IC703+|
Mark,

Hah! Well, at least someone is happy. My comments were based on a
comparison of the audio dsp that comes with the 703 vs the audio dsp
that comes with the yaesu FT-100D. In spite of the FT-100 being
marketed as a mobile rig, and therefore more likely to be used for phone
use, the dsp has the ability to provide a bandpass function which I have
found to be useful in both phone reception and cw reception. The
standard IF filter I have in the FT-100D for cw use is 500 HZ and the
dsp can provide a narrowing down to 120 HZ but is most useful (for me)
at about 250 Hz. Now with the 703 the dsp is mostly set as a low pass
filter function which does help but really the 703 and the FT-100D are
radios with a different focus. As a QRP rig I would expect that the
703 to bewould be used mostly for cw, maybe that is a false perception,
but if so, then I would have expected the radio to be equipped with a
dsp that is more useful to the cw op. All things considered, however,
the 703 mainly competes with the FT-817 and the FT-817 doesn't come with
any dsp at all, although aftermarket products are showing up now. In
any case, a norrow IF filter for cw use is available for both radios and
they make a world of difference. My first impression of the operation
of the 703 was on 40 cw on a weekend without a cw filter and it wasn't
good. The FL-52A helps a lot and there are those who have reported
terifc results with the InRad 400 Hz filter.

Minor complaints notwithstanding, I like both the 703 and the 817 a lot.

That's because probably many registered members don't even have the radio,
therefore there is nothing to register. Like myself, I registered so I can
get all the info (positive and negative) about the radio to my e-mail.

Based on opinions of those members who have the radio + other sources, i
will make a decision to buy it or not. I bet half of the registered members
don't even have the radio....

Zoran, ve3esp

John Oppenheimer <kn5l@... I have removed the data table from my web site. I removed it because I
fear that the data did not represent reality. My problem is the relative
small number of reported radios. There are now 342 members in this

Jim,

If you go to www.icomamerica.com, then select downloads, then select
instruction manuals, then select PDF instruction manuals, then
select IC703 60m Addendum it will instruct you how to use your 703

Hmmm... doesn't look like a mod for those of us with units purchased in May 03'! It looks like
nothing more than setting up the radio to operate on 60 Mtrs. Mine won't transmit there after doing
what they suggest. I think we need to do what Icom suggested to the other chap. Now, when I wrote
them shortly after the 60 Mtr band came out they told me they had no mod, nor intended to produce
one! I'm guessing that once the Japan engineers created the ability for the new units to at least
TX there, these instructions came out. Note, its not recognizing in the software that this is a new
band, you're instructed to save each freq. as a memory channel (giving me the impression they just
added the diode on new production units and published the instructions).

Mine is, Ser# 151001 May 03'

transmit.

BTW, I have a PDF file which I believe orginated from ICOM which

I have the 3.3 kHZ SSB filter installed and I can listen AM signals
using SSB modes with normal filter 2.4 and wide setting as 3.3

The instruction book (page 49) tells for AM the narrow filter is
fixed, so it's always 2.4 kHz, but is the wide AM filter also fixed
having the (too) wide 8 kHz one, any tricks to set the 3.3 filter
for AM wide one?

I just spoke with ICOM Service, (12-29-03), about the 60 meter mod for the ICOM 703 and was told the following: There are TWO mods for the radio that will allow 60 meter transmit.

1. This first mod is to ADD a surface mount Diode on the 13th pad to the left of the "UT" mark on the main board. The ICOM part number for the diode is 1790001250. Once you have done this the radio will transmit from 5.0 to 5.5 MHz.

2. The second mod is to REMOVE diode D5806 on the 6th pad to the left of the "UT" mark on the main board. You will now be able to transmit anywhere from 1.6 to 29.999 MHz.

The first mod adds an Amateur Band to your radio and the second one opens up the radio to transmit everywhere.
In case you missed the previous post, I have radio #1802550, HF only and it does not respond with 60 meter transmit when used on that band, so the information that is posted on the ICOM site about 60 meter operation "assumes" that you have done one of the above mods.
I did not receive information about when future radios will have mod #1 installed from the factory.

I'm using my new 703 for PSK31 using the Tigertronics SignaLink SL1+
interface. Since the interface uses the RJ45 microphone jack, the
microphone has to be unplugged to use PSK31 -- and then plugged back
in when operating SSB. (I know, there's two mic jacks but the mike
still has to be unplugged so as not to get extraneous noise thru the
mike).

My question is: Is there a good way to keep from having to

I subscribed on-line to HFPack and the Adventure Radio Society.
These are the guys with QRP rigs, small homebrew antennas operating
from parking lots and hiking trails. Some do it just for the fun of
it and others because they are apartment and condo dwellers. Lastly,
I packed away my 100w rig, sold my digital gear and got a QRP rig.
Now when I have a simple phone QSO with another guy on low power with
a compromise antenna it's more of a thrill than that big DX station
or weekend of contesting I used to enjoy.

I sent my 703 in for a repair to the keyer and the 60M mod in early
Deccember. It arrived, per UPS, on December 8th. ICOM logged it into the
repair shop on Dec. 9th. I had been told the turnaround time would be 2 or
2 weeks plus return shipping time. I called on Dec 12. and was again told
it would be 2 or 3 weeks. Today, Dec 31 I called again and spoke with Mary.
At first she said the turn around time would be 4 weeks. After I said I had
been told 2 or 3 weeks she said she would expidite the repair and that I
could call her if I had a problem. Later today Dan called. He said that he
could not duplicate the keyer problem. I asked if the antenna was near the
radio. He assured me that it was right behind the radio. I explained that
I had fixed the problem by connecting a jumper cable between the grounding
screw on the back of the radio and the metal base of my paddles. He said
that sounded like the keyer was not properly grounded and that he would fix
it. He said that he had already installed the 60 meter mod by installing a
diode. He said ICOM's policy was not to do the mod that would open up the
radio by removing one of the diodes. I explained that the keyer problem had
been reported by many IC703 owners on the internet. I purchased the radio
in March 03 and Dan said the repairs and return shipping costs were covered
by the warranty. I will report how the repairs work when I get the rig
back.

| 893|893|2004-01-01 07:32:47|John Oppenheimer|Keyer Lockup discussion|
It is my opinion, based on reported serial number ranges and number of
reported CW lockups, that all 703 so far have identical susceptibility
to locking up in CW mode. The probability of experiencing the problem
has all to do with the antenna system being used with the radio.

There have been many threads in this group about what Icom did wrong. My
opinion is that the development engineers know how to filter accessory
lines and that the highest probability is missing capacitors caused by a
production problem, which was reported here some time ago.

I also believe that the development engineers do things for a reason.
With that logic, there must be a reason why the key jack ground is not a
pure ground, but has some resistance to ground. For this reason, I am
not in favor of the common fix of grounding the key jack ground.

Probably fact, the radio locks up in transmit when there is some RF
current imposed onto the key jack lines.

The non radio modification solution to the lockup problem is to remove
the RF current from the key jack lines. But first there needs to be an
understanding where the RF current is coming from.

My theory, based on some experience, is that the RF current is coming
from the antenna feedline. It is well known that connecting a coax
directly to a dipole will allow RF current to be imposed onto the coax
shield. I submit for you consideration that RF current flows down the
feedline, around the radio case, out the key line and finally to your
fingers near the key. Because there is a resistor between the key jack
ground and radio case ground, the RF current causes a voltage drop,
causing the key logic to lock up.

I have tested the theory using my 703. My system configuration is a 20
meter ground plane vertical, approximately 150 feet of coax, the IC-703,
and a CMOS4 keyer and key. On 20 meters all is OK. On 40 meters, which
the antenna tuner will tune the antenna to, I experience lockup.
removing my hands from the key will allow the rig to unkey. I then added
some ferrite beads onto the feedline to choke off the feedline RF
current. The problem went away.

The reason why all is OK on 20 meters is because the antenna is a
textbook perfect ground plane vertical with four tuned radials. It
probably has a good RF ground at the antenna, so little RF current will
flow down the coax shield. On 40 meters there is not a good ground, 1/8
wave radials are not make for a very good ground. So RF will flow down
the coax shield causing the problem.

My recommendation for curing the problem with the present 703 production
run is to try to fix the antenna first. If you are experiencing the
problem, look closely at your antenna configuration. For dipoles, use a
balun. For verticals, have a good ground. Long wire antennas fed at a
low impedance point need a good ground at the tuner. Or, choke off the
current with a ferrite choke on the coax.

If the antenna fixes do not work, then I would try a .01 uf capacitor
between the key jack ground and chassis ground. Then try .0047 uf
capacitors between the key lines and chassis ground.

John
| 894|893|2004-01-01 19:23:39|Tom W.|Re: Keyer Lockup discussion|
John,

You offer some good advice, given the realities of the radio's design.
However, it's my understanding that this radio is marketed as a
portable radio, and I note that the manufacturer supplies a backpack,
complete with antenna attachment point with the radio as a promotion.
The realities of manpack or portable operation often preclude use of
optimum antennas; therefore, I predict that most people will have the
lockup problem.

My own observaton is that the keying circuit in this radio is
unusually sensitive to RF. I noticed the lockup problem when I first
tried to operate CW using the antenna at my house (a popular
commercial vertical fed about 20 ft above the shack) and the same
ground connection used on my regular HF base sataion. The antenna was
installed in accord with the manufacturer's instructions (but of
course there could still be some stray RF on the feedline); however,
none of the other radios I've used from the same operating position
(IC-775, IC-756, IC-706, and FT-817) had keying problems. Similarly,
the '706 and the '817 had no keying problems in either my mobile
installation or in the field using a coax-fed dipole, while the '703
locked up every time. A little RF on the feedline? Perhaps. But the
point is that designers of the other radios somehow managed to build
around the problem...or they got lucky. Perhaps it was the evil
marketing department's decision to market the radio in an application
it wasn't designed for. I doubt it, but....

That said, with the addition of a simple ground strap (or cap) to the
key jack (a 10 minute operation) the problem is solved. Personally, I
don't think one should need to be too worried about perfect grounds,
baluns, chokes and the like while setting up an antenna in the wind
and rain out in the woods, so I favor the internal fix.

The '703 is currently my favorite radio. If this one disappeared, I'd
buy another without hesitation. I'm just glad that its one flaw is
something even I can fix myself.

Tom, KC5UN




| 895|895|2004-01-01 19:52:45|mike bryce|IC703 keying problem|
Hummm.. I agree.. A radio designed for portable use should not
have the lock up problem on cw. Make you wonder if anyone at
Icom packed the thing up and took it for a trip to the local park.

I have tried all sorts of RF chokes on the antenna line, power
lines, and even the key line. Still the problem will not go away.
Swap out the 703 and put in the 706 using the same power
supply, key and antenna, results in no cw keying lock up
problem.

bottom line, Icom has a problem and won't admit it. They should
at least send out an tech update and some fixes.

mike, wb8vge
| 896|895|2004-01-01 20:09:02|Tom W.|Re: IC703 keying problem|
Well, I'm not sure that they really know about the problem in the
institutional sense, so it's not a matter of admitting or not
admitting anything. Field reports sometimes take a while to make it
around an organization. (They had no problem admitting that they'd
gotten a bad batch of rotary encoders for the '775, and replaced mine
free [way out of warranty].)

Yes, swapping out the '703 with a '706 was a telling test. The '703
locked up at 10 w, while the '706 worked fine using the exact same
antenna and accessories at 100 w.

Hi All,

Went out to Red Haw State Park her in south central Iowa today and
took the 703+ portable. I sat at one end of the park where I clamped
the MP-1 to a handicapped parking sign which put the base of the
antenna at about five feet above ground. The radials were deployed
and anchored somewhat symetrically at the base of the antenna. I
worked three station one being DX, V51HK in Nambibia coming in at
5x9. The 10 watts got me a 5x2 report but it's better than a kick in
the pants. The two stateside stations were booming in at 5x9 and I
received similar reports from them. The 703+ and the MP-1 combo seem
to be doing a good job so far. My fingers are crossed.

in this group, 1501405, the next one down is 1501167 (which reported
keying problems). Maybe you have a newer HF+ unit with the capacitors
installed.

I don't remember any reports that the capacitors were installed, only
speculations. The newest HF only SN is 2001109 with reported keying
problems.

Anyone out there have a 703 HF plus close to 1501405 with a keying
problem? N0EHQ has SN 1501211, Ed, any keying problems with it today
during your outing to Red Haw State Park?

During my outing to the park I was operating SSB only. When I use CW
I use a straight key so I can't truthly say if I have the keying
issue or not. But now that I think about it I could put the rig back
to the default key setting and try it that way. I'll try it and post
a followup.

I don't think that it matters what key mode the rig is in. I experience
the problem in straight key mode. I use an external keyer with my 703.

I have just done the first 60 meter mod. (add a diode at 13th pad to
the left of UT). It permits transmit on 5.0 to 5.49999 MHz. There
are corresponding band marker beeps. It does not add a separate 60
meter band which is selectable using the band selection switches --
but the general band will still work for this.

The SMD diode which is added to the board is very small. I needed
reading glasses and a magnifier just to make sure I had the part
oriented correctly. I found soldering it to the board to be a real
challenge -- but this was my first experience with SMDs. Icom
charges $0.80 per diode, so I ordered three to have backups if
necessary.

The new IC703 has been well used these last few days with some good
openings to the USA and Canada so plenty of "cross pond" QSOs on 10m
SSB.

Signal reports continue to be very good and I've even managed to be
first in a queue on some responses to other people's CQs. And all
this with just a random wire (about 60 feet long) down the garden at
about 15 feet above the lawn tuned against a central heating ground!

I have also used the rig on CW with a straight key with no problems
on bands where the ATU matches the random long wire OK.

Overall I am very pleased with the purchase. Lots to explore still
like the memory keyer and the whole memory scene.

I lost audio from the speaker and rear speaker jack but the jack on
the front of the radio works with either headphones or a speaker
attached. In addition, when the radio is in CW mode, the electronic
keyer is always on even when that menu is selected as off. The only
way I could defeat it was to select using the buttons on the hand

Hello Group:

Having looked at the photos that John e-mailed me I decided to take
another look at my 703+ (SN-1501405)for the capacitors shown in the
photographs.

1- Bottom of Main Board revealed that my unit has the two capacitors
installed at the DOTK (dot) and at DASK (dash)lines.

2- Top of Main Board is a different story. The photograph shows the
location of two capacitors close by the CUP. However, to get a look
at these one must first remove (unplugging delicate cables) the UT-
106 unit which is mounted via velcro to the top of the CPU unit which
in turn has a metal cover shielding the CPU. The shield is soldered
to the main circuit board. Needless to say I did not attempt this
so I can not verify if the capacitors are installed directly at the
CUP DOTK and DASK lines on my unit.

If these capacitors were not installed at the factory during
production it will be extremely difficult to do a retro fit. I can
see why ICOM would not want to do this as a recall as it would be
very time consuming and expensive. Being an Electronics Techologist
by trade I would not even attempt this for fear of damaging the main
circuit board when trying to unsolder the CUP cover shield.

I have received my IC703 (SN1801301) back from ICOM America. The runaway
keyer appears to have been fixed. I could not duplicte the problem using
the same paddles, antenna, and frequenies that caused the keyer to runaway
in the past. I have not yet tested the rig using an outboard keyer (TICK1)
yet. The 60 meter mod also appears to work. Transmitting on 60M seems to
work but no one answered my CQ.

In summary, the technician was unable to duplicate the keyer problem but
upon hearing my description of using a jumper wire from the chassis ground
screw to the keyer base, he said that sounded like the keyer needed to be
grounded and he would take care of it. I did not have to explain that I had
already gone through the grounding, torroids on the keyer line and the
capacitors at the paddles cures that did not work.

I was charged for shipping but not for parts or service.

I've had my 703 abt 3 weeks and so far no problems (cross fingers),
mostly working PSK31 into a G5RV Jr. dipole up 30 feet. Great fun.

I'm going to try CW soon but have a question on one of the menus. On
the M4 menu in CW mode, there's an item "1/4." The manual only says,
when set, it allows "fine-tuning." I can find no further explanation
and cannot determine that anything changes or that any controls work
differently when it's set. Does anyone know more about this?

Hi Al,

Hope you enjoy the '703 as much as I have. The '1/4' feature drops
the tuning rate of the dial to 1/4 the normal rate to allow fine
tuning of CW signals. It shares this feature with several other Icom
radios.

I was in my 1987 white Ford Taurus Wagon Radio Platform, operating
an Alinco DX-70 to an SGC 230 tuner bolted to the inside left rear

Charlie,

Good to work you. You were pretty strong on the peaks down here in
Houston.

The '703 is quite enjoyable in the mobile application. I haven't
really noticed too much difference in terms of who I can work since I
swapped the '706 for the '703 in the car. If I can hear someone
through all the crud (QRN) here in Houston, most folks can hear me
with 10w. Again, most of the credit goes to folks on the receiving
end of our 10w signals -- they usually do most of the work.

Cheers,

Tom, KC5UN

Although I have not received my 703 Plus back from Icom yet, they tell me that it is on the way. The problem was an "open FET driver" according to the Icom tech that I talked to on the phone. My serial number is 1501091 and my problem was no output power. I was running PSK31 at 8 watts output when the radio went south. I'll let you all know if I encounter any more problems.

Hi Steve,

My 703 went south too while running PSK at 6 watts. I was getting
long winded and my typing speed isn't too good either. Right, wrong
or indifferent it looks like anything that could be considered as
key down taxes the driver transistor. The 703+ I got as a
replacement seems to be working OK on SSB and CW so far. Truthfully
I haven't had the nerve to try it on PSK. My rig is serial #
1501211. Good luck with the repair and let us know how it holds up.

| 932|930|2004-01-14 05:29:19|Tom W.|Re: My 703 plus repair|
Many folks run their 100w rigs at the 25-30w level when using PSK --
keeps the signal cleaner, and the transmitter cooler. I've never
tried the '703 on PSK, but the '817 gets really hot at 4w output after
a minute or so. Cranking it back to 2w keeps it from getting too
warm.

Perhaps 30% of full power would be prudent with the '703 as well.

Hi,Im going to buy IC-703 mostly to operate CW with a straigth key.
I have a dipole antenna for 20 and 40 m, after i read your posts
about a problem with key lock i wonder if it is a good buy I first
had a ts-450 wih have a problem in the cw section so my main concern
is if a dipole works great with this rig wich in my opinion is
tecnical good.

Hi,

New to this group . . . but scanned all 900+ entries . . . and read
all the posts about the cw/rf problems reported by some.

I am pretty much a die-hard Icom fan and am somewhat dismayed that
they are not being forthright about this problem. In fact, I called
tech support yesterday and asked specifically about a 'problem' that
keeps popping-up in both this group and on eham.net.

The tech support guy [who shall remain nameless, but has been very
knowledgeable and helpful in the past] basically said there was no
problem. Claims he had a 703, operates cw, and never encountered any
problem. He stated the problem was 'users' and their mis-matched
antennas. He also stated that only 'one' 703 has ever been returned
to Icom Repair for this 'imaginary' problem.

I believe there is a problem . . . there is no way that all the users
reporting difficulty could be doing something wrong with their setup.

I tend to agree with the poster that felt that Icom let the key
input 'float' for a reason . . . and that running the extra 'ground'
might not be the best answer, even though it cures the keying problem.

So . . . the questions: has anyone received a definitive answer from
anyone at Icom that a problem does exist? What about the 'missing
capacitors' report? Has the problem been eliminated in the latest
units shipped? Does the problem exist in both the 703 and 703+?

My opinion:
The CW key lock trouble can be easily cured by the end user.
The 703 has ( according to all of the reviews ) a very good
receiver.

If you buy a rig with a bad receiver you cant cure that!

For 40 meter you need a good receiver.

My 703 had the problem. Even operating into my MFJ 1KW dummy load... I
fixed it with the ground wire. (Less than 5 minutes work to open up the box
and add the wire). Has been a beautiful rig ever since. I don't have the
CW filter for the rig, and wish I did when working busy band conditions.
Lately 40M has been so empty it is not a problem.

I also added the diode to get 60M coverage. It is a bit tricky if you don't
have surface mount hold down equipment. Mine went smoothly, and the 60M
seems to program fine. I can hear people, but need to cut another wire on
the dipole for 60M. (It has 5 wires on it now. The tuner can't seem to
pull the 80 or 40M to 60M...)

Nice rig. Good receiver. I can hear everything on it I do on my 756 pro...

earth ground on the rig also. I worked my first VK late yesterday

little 703 continues to amaze me. What a receiver!I have had the unit

| 941|941|2004-01-15 16:27:04|Igor von Uberwald|Antenna tuner diode mod?|
Hi all,

Some time ago there was a mention of removing D5813 on the main
board to enable the tuner to be used of a far wider range than is
possible at the moment. I have taken a good look at the circuit
diagram, and it seems to me that the tuner could indeed match a
large range of impedances

Has anybody actually done this mod? The only drawback that I can
think of is that the tuner would always be in circuit - not so handy
when using the rig as a BC receiver: but even that could be got
around with a little jiggery-pokery, I think.

C'mon - 'fess up, as the colonials would say.

When I switch through the bands via the "band" buttons it switches
for 160m to 10m normally. Now I have the 703+ so I do have 6m. My
question is why as soon as I get to 10m do I still have to bands left
before I get back to 160m? If as soon as I pass 10m, it goes to say,
45.000MHz, I can tune around and then if I hit the band button it
then switches to 50.125. If while in the previous area if I tune from
45.000 to the begining of the 6m band, and then hit the band button
again I seem to have that "extra" band in there once again.

Am I missing something here? :)

I have not found the exact sequence to move the SWL band stacking
frequency to a different band. Try tuning to say WWV at 5 MHz, then hit
the band button, see if that switches the SWL band to 5MHz.

| 945|942|2004-01-15 23:27:25|Al Hearn|Re: Switching bands question?|
What I have found is the following:

The "extra" band is the General Coverage Receiver (GEN) band. If
this band is set, say, to 5975 kHz (BBC World Service), then in the
sequence of bands, it shows up beween the 80 Meter and 40 Meter
bands. If you change the frequency to, say, 12020 kHz, the band
sequence changes so the the GEN band now shows up in it's new logical
sequential position between the 30 and 20 Meter bands.

Now, interestingly, if you tune the GEN band into a ham band, say
the 20 Meter band, then the GEN band becomes the 20 Meter band at
the new frequency, and the "new" GEN band pops back to the frequency
you were at before you changed it -- and the band sequence is
correct once again.

However, if you do the 60M mod that removes the diode, then I don't
know how all this would get handled. The mod that adds the diode
should work OK, as above.

As far as I have seen on my 703 (HF/6m, with one missing diode),
the band selection stays the same. I went to the "general-
coverage" band, and then tuned it down to the 5.3 MHz range.
Until I program those 5 channels into the 703's memory, I can
use the band up/down buttons to get to that range.

Back to work... 73!

Hello all
I am new to the list and wanted to ask a few questions.first off I am looking at getting a 703 as i was getting tired of all the equipment i had going and i just want to make things as simple as i can for operating.one of the things that intrigued me was that the radio has a tuner built in.i have a gap challenger antenna and was wondering how well the 703 will work with it.another question is do any of you use the 703 as your only radio?i know its only 10 watts on ssb but i was curious about what can be done with 10 watts only?also are there any known problems that i need to be aware of.thanks for listening to me.

Welcome Mike.

The internal tuner does seem able to match a wider range of
impedances than is claimed. I'm using a random wire (about 50 feet
long) down the garden and this tunes up on 6, 10, 12, 17, 30, 40 and
80m with no problems. It won't match on 160m or 20 and 15m properly.

I am sure the IC703 working as your only rig will be fine. I've used
an FT817 as the only HF rig (apart from homebrew 1W or less rigs) for
several years and with patience you can work anywhere on the planet
with 5W of SSB, data or CW. With the IC703 you have 3dB more power
AND a speech processor so I'm expecting you to work DXCC inside 6
months ;-) Go prove me wrong my friend!

Good luck and enjoy it.

Well that's what happened.

I did a reset on the radio but now the radio shows high SWR, 10:1.
My external watt meter shows no power out. Oddly though the 703's po

Well after doing a CPU reset, disconnecting the antenna, and
rehooking everything back up it is working fine. It didn't make
sense that the radio was still showing output on its meter. I did
call AES and spoke to someone who was VERY helpful even knowing the
radio was not purchased there and was not under warranty. I believe
it was Al.

I appear to have suffered a transmit driver failure. My previous and
only HF rig is a Kenwood TS-530S (purchased in 1981), so I am very
unfamiliar with operating modern rigs. Before I contact ICOM and/or
my dealer (AES) I want to see if there is perhaps something very
obvious that I'm missing.

I have an IC-703 (HF only) which I got at Christmas time. Around the
first of the year I installed both the ICOM FL-52A 500 Hz filter and
the 60 meter mod which adds a diode. Things seemed to be going well
but I had not put the rig on the air for the last couple of weeks.
Yesterday I tried to put it on PSK-31 -- no luck; didn't seem to be
getting any rf output on the Daiwa CN-101L SWR & Power meter
connected between rig and antenna. Went back and tried both SSB and
CW -- still no power out as best I can tell. Some symptoms --

when try to adjust mic gain get no ALC reading at all

when try to set the manual tuning function on the antenna tuner
(having previously done a tuner reset), the unit goes into Tx mode
for about half a second with no indication (i.e., relays clicking,
etc.) that any actual tuning is being done and then returns to receive

when transmit test message on CW using the internal keyer, RF power
set on H with semi-breakin, get indication of very low power out,
i.e., only the very left square on the meter bar indicates power and
even then not on all characters; with RF power set on 5, get no
indication of any power output

when transmitting on SSB, no matter what the mic gain setting, no
indication on ALC meter, no indication on power meter, and indication
on SWR meter is always 1.

All the above symptoms were the same both before and after doing a
CPU reset.

Does this appear to be a drvier failure? Is there a chance it
results from something I did in putting in the filter or the 60 meter
mod? Or is there a possbility I've just messed-up some menu setting
somewhere?

TIA

Jim, WE2S

| 955|953|2004-01-19 17:39:01|Tom W.|Re: TX Driver Failure Help|
Unfortunately, what you describe is what I experienced when my driver
failed. Mine did come back to life for a few hours, then failed again
-- something I thought was odd.

I called Icom service and described the problem and my troubleshooting
routine (very similar to yours). The tecnician was very helpful, but
the only thing he could suggest that I hadn't tried was a master CPU
reset. He told me to send it in if that failed. Twenty days later
(including the Thanksgiving holiday) I had it back. The service order
paperwork said the transmitter driver transistors were replaced.

It's worked fine in daily service since then. Anecdotal evidence
suggests that once they're fixed they stay fixed, further suggesting
that they got a batch of bad components (absent any other changes made
while replacing the driver transistors).

Good luck,

Tom, KC5UN

I wanted to report to the group that I have performed the 60 meter
mod as posted on the ICOM website, i.e adding the ICOM diode to pad
number 13. My 703 now transmits on 60 meters.
The only other thing that has changed is that now my band
edge "beeps" have "moved". On 40 meters my band edge beep is now at
6.900 and again at 7.500. The radio also transmits over that range
and the antenna tuner also works over that range. Here are the band
edge beeps and transmit/tuner range for the other bands.
160 meters is 1.800 to 2.000
80 meters is 3.400 - 4.100
30 meters is 9.900 to 10.500
20 meters is 13.900 to 14.500
17 meters is 17.900 to 18.500
15 meters is 20.900 to 21.500
12 meters is 24.400 to 25.100
10 meters is 28.000 to 29.999
If anyone else has done the ICOM 60 meter mod - could you report
if your radio now transmits and "beeps" to the above?

I will be buying this rig in the next couple of weeks for camping
purposes. What will I need along with it?
1. I don't have a good idea of what the power cord looks like? Is it
the standard kind you hook into the posts on a power supply?
2. I have a portable power station that has a 7amp gell battery in
it. It has the cigarette type output plug in the front or posts in
the back. It has a 9v output on the side, but would require a small
adapter type end on the cord.
Would this work for portable power, or should I go with the Icom 9v
battery accessory? Do you need to buy the specific charger that goes
with it, or will another charger do?
Thanks!
Beverly
| 960|959|2004-01-22 15:39:14|Tom W.|Re: Accessories for the 703|
Consider one of the optional filters (CW or SSB) from Icom or Inrad.
You might also look for a weathertight container if you're going to be
doing serious camping (away from a roadside campground).

DC power is delivered to the rig via a funky connector on a short
pigtail protruding from the back of the radio. The cable that is
provided to mate with that connector contains fuses and -- I think --
bare wire on the power supply end. You can use whatever plug or lugs
match your power supply (but you supply the connector). The '703
instruction manual contains some illustrations and is available on the
Icom web site at:

http://www.icomamerica.com/support/manuals/ic-703.pdf

I think you'll enjoy this radio.

Tom, KC5UN


| 961|959|2004-01-22 16:40:03|John Oppenheimer|Re: Accessories for the 703|
The 703 power cable comes as a pigtail, nothing on the "to power supply"
end of the cable.

Your 7AH power station should be just fine. I use a 7 AH Gel Cell with
my 703 and get several house of operation time. See http://kn5l.net/qrp/
for more details.

An interesting situation last night. While operating, I noticed that my
output power would jump between 5 and 10 watts. This did scare me a
little at first because I worried that my transmitter section was
failing. Then I checked the battery voltage and noticed that it was
falling into the low 11s. The 703 was switching between the low and high
voltage settings. I normally don't let my battery go much below 12 V,
but this time it did.

BTW, the 703 does have a DVM on the input voltage, a quick push of the
power button display input volts.

Beverly,

Welcome to the world of IC-703 ownership! I think you'll really like
the rig once you get used to it.

The '703 will run directly off of 13.8 VDC. The power cord is
several feet long and comes with stripped and tinned wire leads on
the end that goes to your power source. My power supply has banana
jacks on it, so I soldered banana plugs to the ends of the leads. Do
what suits your needs the best.

Have you thought about antennas? I really like the SuperAntennas MP-
1. It breaks down small enough for backpacking but performs quite
well when set up. Ditch the cheesy counterpoise wires that they give
you and make something realistic to replace it. You may have to
invent a suitable means of mounting the base of the antenna. The
bracket that comes with it is intended for attachment to some kind of
flat surface, such as a picnic table top. You could probably make up
some kind of arrangement using a long metal tent stake so that the
antenna could be ground-mounted. Bring along a stubby #2 Phillips
screwdriver to tighten and loosen the 1/4"-20 Phillips head screws on
the antenna bracket.

Someone else suggested installing a narrow i-f filter. I agree. If
you're going to work CW with the '703, I *highly* recommend the InRad
400 Hz filter. It's only a few dollars more than the Icom filter,
but its performance is far better. The stock SSB filter is much too
wide for anything other than the most casual CW operation.

By the way, since you haven't purchased your '703 yet, I recommend
that you do some serious shopping on the internet and the 1-800
numbers for the best price. When I bought mine back in November, R&L
Electronics in Hamilton, Ohio, had the best price ($40 less than
everyone else!). Prices vary a lot from dealer to dealer, so do your
homework before you fire up your Visa card. Buying from a local
dealer is convenient, but the sales tax will likely be several times
the shipping cost. Some dealers also offer free shipping (Ham Radio
Outlet, comes to mind). Factor that in also.

Again, welcome! I hope to work you on the air some time, 2xQRP!

73/72,
Dean K5DH

Thanks to everyone for your replies!
Another question concerning power while mobile:
If I'm using my 12v power station, as I use up power, I will sooner
or later get down to 9 volts, right?
Now, the 9volt accessory at Icom for this radio says you can run at
9 volt for up to 7 hours?
Would a regular 7amp gell cell do the same thing once it's down to
about a 9 volt level?
Sorry, I'm not very technically inept on this sort of stuff!
Is anyone else using this 9 volt accessory? Is it sort of a
container where you can replace the rechargable 9v batteries
yourself as needed? I like the size of it...in a teardrop trailer,
room is at a commodity.
The antenna is an interesting topic also. I mainly use 20 meter and
75. Had figured on using dipoles...but could get interesting
finding the room to string a 75 meter dipole at times.
Also, thanks for the tip on a waterproof container. I hadn't
thought much on that. I can't wait to get it!!!!

| 965|959|2004-01-22 19:25:33|JBCrafts|Re: Accessories for the 703|
Bev,

battery container... a good old fashion GI surplus M60 ammo can.
www.cheaperthandirt.com has built in handle, water tight seal... you will
need to put a connector on it or open the lid when you want to get to the
battery.

I use a couple 12v 4AH cells instead of one 12v 7AH. I found that the 12v4ah
perfectly fits a GI surplus M16 ammo pouch. I use the short magazine pouch
(4 20 round mags fit the pouch), you can take the grenade straps off the out
side of the pouch. The pouch has ALICE clips so you can put it on a belt...

SOMEDAY I am going to take pictures of my setup..

One other thing that I do, I like Anderson Powerpole connectors. I carefully
removed the original Icom power connectors and installed Powerpoles. This
way, I can interface to any power source in the house or motorhome or
backpack. I removed rather than cut the old connectors - just incase I sell
the radio and the buyer does not like Powerpoles.

I DO NOT have optional filters, but this is on my "to do list" for the
Hamvention.

| 966|959|2004-01-22 22:37:07|John Oppenheimer|Re: Accessories for the 703|
With respect to battery run time. It is a function of the capacity of
the battery that your are using.

Sealed Lead Acid (SLA) batteries are rated at a 20 hour discharge rate
to 10 volts. Or a 7 Ah SLA will discharge to 10 volts after 20 hours
with a load of 350 ma. As the current is increased, the amps per hour
decrease.

For an example discharge table, look at
http://www.panasonic.com/industrial/battery/oem/images/pdf/Panasonic_VRLA_LC-R123R4P.pdf
for a 3.4 Ah, look at the "Discharge characteristics 77F" figure.
Notice the 0.17A (3.4 / 20) line, and see the voltage, near 10 at 20 hours.

The IC-703 draws about 500 mA with the lights on, then you transmit
some, so pick an average current of about 850mA. From the chart, to 10V,
that's three hours, or 2.55Ah. But if you want to stay at 10W and want
to keep the voltage close to 12V, then only about an hour and a quarter
of operating time with a 3.4Ah SLA.

You can extrapolate, a 7Ah SLA will drop down to about 12V in about two
and a half hours with the 850mA current.

| 967|959|2004-01-23 00:30:23|flhtci97|Re: Accessories for the 703|
Hi Beverly,

The 703 has a minimum operating voltage of 9 volts. Once the supply
voltage drops below 9 volts the display will flash off and on; it's
kind of scary at first until you realize what is going on. As for
the Icom battery pack, I can offer no input. I use an 8 ah battery
along with a 3 ah quick charger from the Power Port Store. It's kind
of a pricey setup but the charger will work with the other
affordable 7 ah batteries on the market. Good luck with your
decision.

Ed N0EHQ
| 968|959|2004-01-23 00:33:37|John Oppenheimer|Re: Accessories for the 703|
For pricing, I purchased the 7Ah SLA and charger new, about $20 each,
for a total of about $40.

Jim,

Bummer. Actually, not that it matters that much at this point, but
it's probably the driver that's failed (common problem). The fix is
to let Icom repair it. Data from users in this group suggests that
once they're fixed they stay fixed. Mine failed after about a month
of use, but it's been working fine in daily use since I got it back
from the shop (knock wood).

Mine is still working solid. Only issue is the CW lockup, that they all
seem to have.

Last night I worked EA8BH on 80 meter CW using a Butternut vertical. I
did need to up my power to 10 watts QRO though.

I just leave the DSP on all the time, the notch filter turns off in CW
mode automatically.

Congratulations Bev. You'll love your new 703. Unless you've had a
similar radio before (like the 706), plan to keep the user's manual
handy for a while. It has so many features that it'll take a while
just to try them all out. The internal antenna tuner performs better
than specs and is the radio's best feature, in my opinion.

I've had mine since before Christmas, working mostly PSK31 on 20 and
40 meters at about 7-8 watts, and have had no problems. I'm OK with
the possibility of the finals drivers going out and getting it
repaired -- and then having no more problems, as seems to be the
case with others. It's a great radio and would be worth the little
extra trouble (if it happens). Serial: 1802589.

Hello again!
Well, got the rig all hooked up, checked the swr on my G5RV,
transmitted at 10 watts and I'm off and running!
Got a great signal report from a gentleman in Vermont. (I'm in
Michigan)
SWR was great, about perfect with the tuner.
Al, I have never owned a "little" radio, other than an analog MFJ
rig which wasn't exactly my favorite way to go.
My other rig is a Icom 746, which I love. I'm a big fan of
Icoms..just hope this one doesn't go south on me..it's too much fun.
Is there a "quick read", "how-to" instruction page out there to
bring along portable? The manual is more information than I need
for that.
Next step will be trying some psk soon.

keeping track of this stuff.
Serial number is: 1801369
AES
Bought January 28th

Hopefully I won't have any problems, but I just couldn't wait any
longer to get one. Looking forward to getting it on the air.

Figuring out all the new stuff is probably what I enjoy the most about
a new radio. Seems like I'm always surprised by something that's
really neat that I didn't know about. Not reading the instructions
prolongs that experience.

Hello all,
Most often, when I hold the antenna tuner in for a second to tune, it
makes a very fast multiple clicking noise. Not just one click, but
many. Is that normal?
Tnx,
Bev
| 984|984|2004-01-29 12:22:04|kc8jwa|And|
If you turn off the radio, and turn it back on the next day to the
same frequency, is the antenna still tuned? Does it do it
automatically or must you tune every time you turn the rig on?
Bev
| 985|983|2004-01-29 12:28:27|flhtci97|Re: Normal Tuner?|
Bev,

My 703+ does that once in a while too. It's usually when the match
is not quite 1:1. I suspect that if not matched to 1:1 when the tune
is pushed the tuner will still attempt to find the best match. What
is the SWR at the point that you hear the several clicks when the
tune is pressed?

73 Ed, N0EHQ
| 986|984|2004-01-29 12:34:56|flhtci97|Re: And|
Good Morning Bev,

The rig should stay tuned if nothing has changed from power off to
the next time you power the rig up. I always give mt tune button a
touch to confirm that I have a match just to ensure that I have a
match. The tuner has latching relays to maintain the settings after
the rig is powered off. It sounds like you're having fun.

73 Ed, N0EHQ
| 987|983|2004-01-29 12:38:14|kc8jwa|Re: Normal Tuner?|
Ed,
Well, I'm not sure what the swr is before the tuner, but it was below
1.5 with the tuner.
75 meters, on a G5RV. It seems to tune this home antenna of mine ok
so I'm using it with the G5RV right now.
I have a feeling maybe it is already tuned and I am trying to get it
to tune again?
I am hoping to use a 88' dipole for portable for both 20 and 75
meters. I read an article that it's suppose to be a good antenna for
these bands. Wonder if the tuner will tune it?
Go here to see:
http://www.cebik.com/88.html
Thanks!
Bev
| 988|983|2004-01-29 16:05:21|John Oppenheimer|Re: Normal Tuner?|
The relay chatter is very normal, and very noticeable the first time. My
impulse the first time was to turn the rig off ;-) I had thought that I
had broken it ;-)

The noise is coming from all of the antenna tuner relays changing
position as the SW seeks the best antenna match. And yes, the settings
for many frequencies are saved in memory.

Several new radios acquired recently!

| 989|984|2004-01-30 10:28:05|ve5kc|Re: And|
You might want to go into the setup menu and turn on the PTT auto
Tune function.

With this turned on, the radio automatically tunes any time you
transmit and the SWR is higher than what is should be. It also works
well when using the AH-4 external tuner. I use this function on both
of my Icom rigs and find it works great. This makes things even more
automatic. You will never forget to tune when changing, bands,
antenna or the frequency enough to increase the SWR.

Thanks Ken, that sounds wonderful! One problem though?
I see the feature listed on page 81 of my manual under set mode.
Number 34.
But I can't figure out how to get it setup in the radio. Could you
walk me through the steps to get it turned on? I can't figure out
how to get at all those features listed.

| 991|984|2004-01-30 20:57:41|flhtci97|Re: And|
If memory serves me correctly I don't have the manual here before me
here at work, with the power off to the rig press the frequency lock
button and hold while turning the power on. This should get you into
the setup mode. You can then scroll through the setup features with
the F1 button or use the up/down arrow buttons. To change the value
of the setting of a feature rotate the tuning dial. To get out of
setup mode you should be able to press any of the other F buttons to
get you back where you were.

Refer to the user manual - "SET MODE" (Pages - 74 - 82)

Page 74 tells you how:

Initial set mode operation
==========================

1) - Push [POWER] for 1 sec. to turn power OFF.
2) - While pushing [LOCK], push [POWER] to turn power ON.
• Initial set mode is selected and one of its items appears.
3) - Push [MENU] one or more times to select the desired item.
4) - Rotate the main dial to set the values or conditions for the
selected item.
5) - Repeat steps 3 and 4 to set other items.
6) - To exit initial set mode, push [POWER] for 1 sec. to turn power
OFF.
7) - Push [POWER] to turn power ON again.
• The conditions selected in initial set mode are now
effective.

Number 34 is the (PTT tune function)

Change this to ON

Do most of you use your speech compressor on SSB? I'm not real
familiar with useing one, but am thinking with qrp it might be a help?
Thanks again,

My 703 is not handy at the moment. I think that it has, at default

with regard to speech processing and I get very good audio reports.
Everyone seems to like my transmitted audio so far.

Anyone running PSK-31 on the 703? I'm sure there are a bunch doing
this. My question is if there are any settings I need to adjust for
doing the digital modes. The manual talks a lot about Packet and
RTTY, but leaves a lot of questions concerning the setup for PSK-31.

What setting is everyone using for this mode when going through the
Data port on the back?

I built a CI-V and audio interface device over the weekend and
everything works great, but I'm not sure the audio is really
transmitting correctly is the reason for my question. By the way,
Ham Radio Deluxe software is working great. Good job on the
development of that program guys.

My FT-817 manual was very clear on how to set up for PSK-31.

Hi,

Ideally you'll use USB and make sure the Data option is on. Shout at Peter
PH1PH - he uses PSK31 a lot with the 703.

Data should knock the microphone off I think...

One other thing - get a good external soundcard, you will be amazed at the
difference it can make.

| 1001|998|2004-02-02 17:57:57|Al Hearn|Re: PSK-31 on the IC-703|
You won't get any help from the IC-703 manual for PSK31. There are a
couple of ways to do it -- through the ACC jack, or the MIC jack
(but not the DATA jack, which is for a TNC and RTTY).

I chose to use the MIC jack on the back of the 703 to interface to
my Tigertronics SignaLink SL-1+ because it has 1) audio output
controlled by the AF volume knob, 2) has 13.8V power so that I don't
need an external power supply, and 3) has a PTT line (the SL-1+
doesn't need a serial connector to the computer for PTT).

The MIC cable either comes with the SignaLink or can be purchased at
RadioShack. It's just a short network cable with RJ-45 connectors on
the ends.

The only disadvantage is that the MIC connector on the front-bottom
of the 703 is still active when using PSK31 and the microphone must
be disconnected to prevent unwanted audio from entering. This is
only a problem if you switch back and forth a lot between SSB and
PSK31. The SignaLink really needs it's own MIC jack so that it can
disable it during PSK31 operation. I think other interface units
might have a MIC jack.

Using this interface, when operating the 703 on PSK31, simply set to
SSB USB operation, not Data. It's best to tune the power output down
from maximum. Also don't use any speech compression and keep the
mike gain down to between 5 and 7 to prevent distortion of your
PSK31 signal.

Hi all,

BALDERDASH! I've been using the rear DATA connector since last May,
and it has never let me down. The MAIN advantage to doing this is
that when you use DATA mode the microphone can be left
connected...an ideal situation with any soundcard interface.

Gary,
I do not think you can use the DATA port for PSK31, but it is there for
Packet and RTTY...

here is what I do... I have a IC-706mk2G and a IC-703, and I use the same
set up for both... which is why I sold the FT-817 and bought the IC-703, but
that is not the current topic....

I use the 13 pin DIN. I made a cable that is based on the schematic I found
at www.k6xx.com (whoa, was that Igor's hot breath I just felt?)... and now,
a comment to calm Igor... I also have a RIGblaster M8 [I forget where I put
it... down Igor!], and since it is the M8 version, I made a cable that went
from the (ha!) "RJ-45" to the 13 pin DIN. On the DIN plug, you get PTT,
V/HSEND, FIXED RX AUDIO, and TX AUDIO. I like the fixed rx audio, this way I
can turn the receiver down and not have to listen to over driven audio, some
lid playing DOOM, and the guy that forgot that in the USA, 14.070 is in the
CW sub band and he is not going to hear a reply to his CQ on SSB. I also
firmly believe that neat cables make for good cables, and good cables
prevent problems, so I do not have one cable going to the speaker jack and
another to the mic connector... one cable, one radio. FYI, the M8 version of
the RIGblaster is made for 8 pin round mic connectors, I bought it when I
owned a TS-50 and the TS-50 does not sport AUX in/out connections.

OK, now you set the "VFO" to 14.070.000 (or if you prefer 14.070.150 if you
do not mind missing the guys at the bottom end), and use USB. I set the RF
out to "10" and let the sound card set my actual RF output. My SSB mic gain
is set at 4, since this is where I like it when I actually use a
microphone - good thing I have two Icom's that share a mic model, since I
cannot always find a microphone.

I use the sound card properties to adjust my output, I select the ALC meter,
then I start with the TX audio gain at ZERO, and I slowly increase until I
see activity on the ALC meter and then reduce drive. On the IC-706, this is
about 40 watts. Since I like to run no more then 10 watts, I then reduce the
drive until I see about 10w on the external power meter/antenna tuner.

I get consistent reports that my IMD is -29 to -32, once, I actually got a
report recently that my IMD was -52!

Great post Bob. I appreciate hearing how others do things. I always
learn something new.

By the way, I would like to get a computer rig control interface box
to use more of the nice features of my PSK31 software, but I don't
want to pay the price of Icom's CT-17 CI-V. I know there are simple
circuits but my homebrew days are over. So, I'm wondering if there
are less expensive products out there that emulate the Icom CT-17?

I was looking at the CI-V CT-17 issue and all it is, is a TTL to RS-232
converter... OK!, I could build a RS-232 level converter from a MAX-232,
MAX-233, MC1488/MC1489, discrete components... and started looking for
parts. I actually bought a LTC ???? chip (same as the MAX 232), but I had a
brain storm... I already OWNED a level converter! RTSystems sold me a level
converter to use ADMS software with my FT-50! The RTSystems cable came
terminated with a stereo 1/8in miniplug, that had to be converted to a 4
circuit 1/8in miniplug... WHAT IF~~~ I found the pin out of the FT-50's
mic/speaker/data jack, found the data connections, then metered this to the
stereo plug... OK!!!

I then looked at the schematic for the CT-17!

I then made an adapter to go from the stereo plug on the Yaesu CAT cable to
the mono Icom CI-V jack...

It has worked perfectly.

Bob,

What you just described circuit wise I finished building over the weekend in
an Altoids tin box. My design is a rig control device using the MAX232 chip
and the audio interface circuit all in the same box. It was my second
interface built in an Altoids container. They're great for that purpose and
cheap! Besides, you can eat the mints while you build. Lots of fun and all
the schematics you need are contained in the Interfacing booklet put out by
Peter Halpin and Simon Brown. Sure is fun playing with this stuff at times
isn't it. Everything you need for the audio interface you can find at Radio
Shack.

Go for it and have fun. I believe some of the people that don't build are
missing out on one of the educational parts of the hobby. But, not everyone
is able to or interested in building these days. That's ok too I guess, but
seems to be a bad trend I think.

Have fun building.

Gary

dear friends,
I checked the description at hamstop.com and found this interface to be
connected to microphon and headphone connectors.

I really cannot unterstand why a designer preferes this solutions. All
modern radios including the 703 have a special port for digimodes. I our
times it is standard to use this ports for all digimodes. The 703 for this
purpose has the 13 Pin connector at its back. Also it is a problem with new
Notebooks because they have no RS232 any longer. A good interface should
have a DataVox integrated to make it work without a RS232 cable.

The difference:
At the digiconnector you have seperatet input and output with constant
levels, independent from the settings of the front panel controls or the
menue settings. You have to adjust the software only once when you start the
first time.

Peter:

It seems to me that, ideally, there should be a connector that has
1) 13.8 volts power, 2) constant AF output, 3) AF input
(w/disconnected MIC), and 4) and PTT (or RX/TX). Unfortunately, on
the 703 (and I suspect on most other radios) there is no SINGLE
connector that has ALL of these functions together.

To connect my SignaLink, I initially chose the RJ-45 Mic connector
because I gave priority to having 13.8 volts (to eliminate having to
power the unit separately), at the expense of not having constant AF
and having to disconnect the microphone. I may try the alternate 13-
pin DIN ACC connector (and external power) in SSB-D mode to see
which I like the best. I have to change some jumpers inside the
SignaLink, but it supports all connectors.

I've been a member of this group since soon after it was formed and
been following the postings.

Finally plucked up courage (after seeing the offer of a three year
warrenty) and yesterday purchased 703 Serial No 1201666 #12 EUR1.

It is currently being mollycoddled on the bench in the shack but is
destined for a lightweight pedestrian mobile setup.

I will keep the Group posted on progress. I believe it will outpunch
its weight in this role (I enjoyed the opportunity to field test one
last August).

Operating PSK31 on the 703+ is very simple when using the 13 pin ACC
socket at the back of the radio.

Here are my connections:

Pin 12 - AF detector output(fixed output regardless of volume setting)
- this is the RX audio into the computer sound card, MIC input.

Pin 11 - MOD modulator input
- this is the TX audio output from the computer earphone jack
- my TX audio output level is set to 249 mvP/P or 89 mv RMS,
this transmits a clean narrow PSK31 waterfall signal, does
does not ovemodulate the transmitter. Overmodulating, too
much audio from the sound card, is by far the biggest
culprit, it causes splatter.

Pin 3 - HSEND, when grounded, transmits
- my interface to the RS232 serial port on the computer for
transmitting is simply a 5 volt relay that is driven by the
RTS line (pin 7 of the serial port) through a diode.
- anode end to pin 7 and cathode end to the relay coil. The
other side of the coil connects to ground (pin 5 of the
serial port)
- the diode blocks the negative RS232 voltage when not
transmitting, during receiving
- the relay contacts ground Pin 3 (HSEND) to transmitt

Also, I disconnet the mic from the radio.

I have operated PSK31 for a couple of months now at both 5 and 10
watt power level with no problem whatsoever.


Hope this helps.

OK, I just wired up a cable for the 13 pin ACC connector and it
works fine with my SignaLink. What had me thrown off regarding the
ACC connector was the different terminology for the RX/TX switching
(HSEND) and AF Input (MOD).

So, now I've got everything, including power, on one connector and
can leave the microphone plugged in when operating in SSB-D (USB)
mode. I'll have to play around some and make sure I've got my audio
levels right.

Looking for my CAT cable to come in later in the week for the final
part of the setup.

Thanks guys.

Al,

and I forgot to say in my last posting, that you can use the 13,8V at pin 8
of ACC

Al,
you are right regarding the 13V. But because the floating AF in and out is
much more incomfortable, most users I know use a little 9V block with the
SignaLink.
Thats also right for the FT817.

Peter:

It seems to me that, ideally, there should be a connector that has
1) 13.8 volts power, 2) constant AF output, 3) AF input
(w/disconnected MIC), and 4) and PTT (or RX/TX). Unfortunately, on
the 703 (and I suspect on most other radios) there is no SINGLE
connector that has ALL of these functions together.

To connect my SignaLink, I initially chose the RJ-45 Mic connector
because I gave priority to having 13.8 volts (to eliminate having to
power the unit separately), at the expense of not having constant AF
and having to disconnect the microphone. I may try the alternate 13-
pin DIN ACC connector (and external power) in SSB-D mode to see
which I like the best. I have to change some jumpers inside the
SignaLink, but it supports all connectors.

I've noticed on my 703 (stock microphone) in SSB mode that the ALC
never exceeds or peaks above the "ALC Zone", as ICOM calls it, even
with the MIC GAIN set to 10 and the compressor on. Is this typical?
Why set the MIC GAIN to anything other than max if it doesn't seem
to be overdriving?
| 1023|1022|2004-02-05 04:59:47|Rob Boux|Re: Mic Gain Question|
I can drive my 703+ over the ALC range easy with COMP on setting 2 and mic gain set above 5. In other words anything over these settings will cause the ALC meter to go above S9 or ALC max.

I've noticed the same thing -- being unable to drive past the ALC zone
no matter how high I set mic gain and compression. Common sense
tells me that may not be correct. Absent any test equipment, I set
mine up so that it only showed full output on voice peaks and figured
it was close enough. If memory serves, I think it was mic gain=5 and
compression=3 with my voice and operating style (e.g., not shouting
into the mic). I get good audio reports, but if someone has a scope,
I'd like to know what the signal looks like.

Tom,

It seems to me that these rigs are all over the place as far as
specs. I have a s/n 150001403 that shows no sign of the finals
problem or what seems to be the ACL scenerio. How are your audio
reports?

I am wondering the real deal with the slick Icom 703 rig. How is the
QRP operation in the real world? Are phone contacts decent? or is
CW advised? I'm a happy owner of a 746P and 706G and am quite
interested in the "real" abilities of the 703. I greatly appreciate
any comments and experiences in comparison to the 100W barefoot
operations. I'm very interested in QRP and really need to know if
this is respectful way to get started. I've been playing with the
base and mobile rigs at reduced power settings (10W) and haven't had
much luck. Please let me know what you think! 73 de Brian N8AVR

window to read #598)... the snaps i took are still up... the 703
worked quite well for me... the rig will see a lot more use when the

i've had quite a bit of fun operating QRP... best so far was one-half

I have used the 703 pretty exclusively since I got it last November
and once in a while fire up the 706 IIG. Working from a state park
here in south central Iowa the 10 watts and an MP-1 at 6 feet off
the ground let me make several contacts one of which was into
Africa. The little rig will do the job for you and the internal
tuner is a nice feature too. Good luck with your decision.

| 1031|1022|2004-02-07 01:00:59|Tom W.|Re: Mic Gain Question|
Mark,

Audio reports have been good. Absent test equipment, and not really
trusting second-party over-the-air reports, I left a tape recorder
running at my base station, then drove a few miles away with the '703
in the car and made a few short test transmissions on 10 meters after
the band closed one night. (Yes, it's legal.) I tried several
combinations of mic gain and compression settings before settling on 5
and 3, respectively after listening to the tape. It never sounded
really bad, even using high mic gain and compression values, but that
combination sounded like a good compromise between punch and audio
quality for my voice.

Hope that helps.

Tom, KC5UN



| 1032|1028|2004-02-07 01:19:09|Tom W.|Re: QRP/703-Real Deal?|
Brian,

I wondered the same thing myself. I swapped out a '703 for my '706 in
the car and have been pleasantly surprised at the number of contacts
I've been able to make on a daily basis. And most of them have been
on SSB (which, to be honest, was a surprise to me). The advantage of
having all external accessories and cables plug compatible between the
two radios made swapping them a 5-minute operation.

I usually don't bother calling the weak ones unless I know they're
running near-QRP power too. But other than that, I haven't adjusted
my operating habits very much. Go figure. Obviously, having a decent
antenna really pays dividends at these power levels. Not that the
4-1/2 ft long whip I'm currently using qualifies as decent, but
still....

Cheers,

Tom, KC5UN


| 1033|1028|2004-02-07 02:48:51|Al Hearn|Re: QRP/703-Real Deal?|
I agree with Tom. After starting to use my 703, I was surprised at
how little trouble it was to make good solid contacts on less than
10 watts SSB -- and even less trouble on PSK31. Usually, I get about
the same signal report as I give the other station, who is typically
using much more power.

One of the things that has helped convinced me of the fact that you
don't really need hign power is listening to DX beacons. When I hear
a weak beacon in, say, South Africa transmitting 100 watts, then 10,
then 1, and finally 100 mw, there's usually suprising little
difference, if any, to my ear between the 100 and 10 watt signals,
and not that much difference between 10 and 1. And, more often than
not, the 100 mw signal is readable.

Brian,

I am a QRP fan!!!

I have built over 25 QRP transceivers and have purchased many other
commercial rigs. I have the TenTec 505, 509, and 515. Also the argo 556 and 516,
2-Index Labs Rigs, Sierra w/all mods and bands, etc. I am nearing completion of
5Band WAS- All QRP-All SSB. I only need HI on 80, UT on 15, and 5 states on 10.
All this was done QRP.

I only say all this to indicate that I am not a casual QRP op, In fact I
operated 100% QRP from 1991 to 2002.

BOTTOM LINE: I think the IC703 is one of the best QRP rigs ever made.

This rig absolutely amazes me. The low power consumption is unbeleivable,
compared to other commercial radio. I am truly considering selling off most of my
other stuff after using this radio for the last year.

Hello,
I'm thinking on buying a Icom 703 or Yaesu 817.
I'm reading hear and other posts that the finals can go in as little
as a few hours. Why? If I run the rig less then 10 Watts would that
help? I plan on using the rig at camp in Maine, camping in NH. I
also plan on using the rig in Northern Quebec and Labrador within
the next couple of years. So I need a rig that will work and not
fail. So should I buy a 703 now, wait until Icom fixes the problems
or buy the 817?

There is no such thing as rig that will work and not fail. I think the
703 is superior in many ways to most QRP rigs out there today. I have a
suspicion that the ones in the pipeline today (assuming you buy it from
a high volume dealer) have the driver problem addressed so it should not
be the problem it has been (I am putting a lot of faith in ICOM!).

As best as I can tell the FT-817 tends to blow the finals and the IC-703
tends to blow the drivers. In the case of the FT-817 they have gone to
a replacement part for the final transistor which appears to be more
robust. Interestingly enough, it is the same part as in the IC-703.
The FT-817 final board has a decent heat sinking capability on the
bottom and it is run only at 5 watts so this combined with the new final
*should* make for a more reliable final stage. In any case, it seems
that only a small percentage of the finals in FT-817s are blowing and
likewise there is only a small percentage of drivers blowing in
IC-703s. It is just that in an internet chat group that you will hear
*all* the complaints and most people who are happily using and abusing
their rigs without cooking anything rarely complain. I have both an
FT-817 and a IC-703 neither of which has blown up anything.

I have owned both the FT-817 and I currently own the Ic-703+. The + on the
703 means that it includes 6 meters.
I will break both radios down and let you know my likes and dislikes of these
two radios.

Ft-817

Disadvantages:

1. Small screen. You can change the screen to either amber or blue. For
people that wear bifocals you will need to use your glasses.
2. You will need a separate antenna tuner or make your antennas to exact
frequency and /or band you want to use.
3. Need to purchase some after market stand or (bail) so it can be propped up.
4. To use less volts you really need to use the BNC antenna connector for
your antenna conection.
5. Uses more current then the IC-703+
6. No DSP
7. 5 watts to transmit down to 2.5 watts if you are using internal battery.
You can change it to transmit at 5 watts, battery life drops fast.

Advantages:

1. Good receiver.
2. Smaller than IC-703
3. Has both Vhf and Uhf
4. It has a strap that connects to the radio and you can carry it around
your neck.
5. Easier to use and understand.
6. Self contained, has own battery compartment built into radio.

Icom- 703

Disadvantages:

1. No vhf or uhf bands.
2. Bigger in size and wt.
3. Doesn't have built in battery compartment. Not self contained concerning
power.
4. Harder to understand the use of the manual and operation of radio.

Advantages:

1. You can transmit Max 10 watts SSB or you can decrease down to 0.1 watts.
2. Antenna tuner. Built into the radio.
3. Bigger screen -- don't need my bifocals to see the numbers.
4. Good receiver.

My main reason for the sale of the FT-817, was the extra cost for antenna
tuner, and my eye sight. I just got tired of looking for my glasses everytime I
wanted to use the radio.

Check what are the average cost to fix the Ft-817 finals or the Ic-703+
drivers.

I am happy with the Icom-703+. Someday I would like to buy another Ft-817 to
compare them to each other. Also to have access to internal battery and have
Vhf And Uhf in one radio. Instead of using my Ft-51 for vhf and Uhf.
Both are excellent radios. They just have different options built into each
other.

Now if either Icom or Yeasu could add each others differences, we would
really have a great radio.
I hope this will help you decide which radio you will want to purchase. I
might have left out some of the differences between each radio. These were the
main differences I could remember.
Good luck and enjoy which ever one you buy.

I've owned both and there's no comparison at all.. the 703+ is the best
radio. BIg screen, easy to use, fun battery pack and backpack available, more
power, better specs. Just TRY to get on the local repeater on 2 meters with the
718... too little, too late...

The best, of course, would be a 703+ that has 2 meters !! Maybe at
Dayton....

All this talk of bad 703's. There is a new one on eham reviews.
"Transmitter died in 45 days".
Another: "New rig, finals not working".
Has anyone on this group ever asked Icom what is going on with these
rigs? Has anyone got an answer as to why their radio went bad?
I've read where they get them back repaired and no further
problems...why? Does Icom replace some part with a better one? Did
they have a bad batch of something?
It just seems like Icom would have something to say when these
issues happen? Just curious, since I own a new one.

| 1044|1038|2004-02-12 02:57:56|JBCrafts|Re: Buy a Icom 703 or Yaesu 817?|
oh , let me add to this...

I have owned both the FT-817 and the IC-703...

Please add to the FT-817 disadvantages:
Internal batteries discharge too quickly - the internal battery must have
been an after thought, they had room to spare and needed to fill it with
something useless.

Front panel is not removable.

The rig is sold as an Adventure Radio, but it does not include the marine WX
channels, I still needed to carry a handheld, so the V/UHF section was
redundant.

IC-703 advantage... the accessories are the same between the two, so if you
own both, you do not need two of everything.

IC-703 DISadvantage, the menu system, but they are the same as the IC-706.

Just to add to the advantages of the 703, also has DSP & Commpression
as well as TXCO built in.

I like both and own both. No problems with either except the tuning

Thanks all,

I was able to use a 817 a couple of years ago during a VHF contest.
I made quit a few contacts on 2M,6M and a couple on 430. Was not too
bad considering only 5 watts and small antennas mounted on my back
deck. It's is a neat radio but small to use and see the display.
I think I'll give the 703 a try. I'll be off to coastal Washington
County Maine in a couple of months to do some seal and eagle
spotting with the kids. We are going to camp on the coast and I'll
bring the 703 and give it a try there!

My $.02:

I use the FT-817 as an outdoor radio backpacking. It weighs about two
pounds less than the 703 and is more ruggedly built than the 703. In
this case the 703 has a disadvantage since it weighs more and the
detachable front panel contributes to another failure point. The 703 is
a great portable radio such as at places that the car can be driven to.
It also is a great home QRP rig. The screen is larger and the little
buttons have lights which make them a lot easier to use. I can't see a
damn thing anymore. Anyway, I think the value of the radio depends on
the application. I am puzzled by the detachable front panel on the
703. This adds cost to the radio but is only really applicable in a car
installation. Most mobile radios tend to run more power so I think it
is odd that the 703 has a detachable front panel. I personally have no
use for that feature.

Hi Rick and the Group

The detachable front panel (together with its many other great attributes)
is what makes the 703 such a brilliant pedestrian mobile rig. The
relatively lightweight body can be on your back and you only have a very
light front panel complete with every control you need on your chest in
front of you - exactly what is required for a great few hours of operating
whilst you hike.

Rick,
I am the opposite, the detachable face panel is a requirement that I need. I
like to tote my radio on my back. My radio is in a case, attached to a GI
surplus ALICE frame - I am working on rebuilding my web site to show this
configuration at http://users.adelphia.net/~m10 or www.bobs.net.tc.

I owned a FT-817, I bought a LDG-Z11 tuner, I put all this together in a
WorldPack2 case, married it to the ALICE frame, added a mirror mount antenna
mount and a portable antenna.

I took the configuration on my honeymoon/camping trip. I soon found out that
while it was a really neat IDEA, it was not very practical. I set my
frequency, hit the antenna tuner, all very kewl, but soon found that I could
not QSY, I could not turn the VOL up or DOWN without removing the pack from
my back, not very convenient at all! I did make contact with other /PM
manpack stations, and I impressed the heck out of our host in Montana, when
I was able to work back into the "east" from a portable rig on my back and
he could not with a KW and a tribander. Yeah, had a lot to do with band I
used, antenna position, mode etc... but I was able to do it and he could
not.

Since I already own a IC-706mk2g, I tried this configuration, it worked! it
did all that I wanted, needed, but it sucked down the electrons faster then
I could refresh the water bowl.

I then bought the IC-703, it is not a "perfect" radio, but it fills the need
right now.

Hmm, that sounds cool. I hadn't thought of that but my application is
somewhat different. I usually use the ft-817 in the backcountry and as
such the radio sits stuffed into the pack somewhere and I don't try to
use it while I am hiking. The radio getes used in a static type
environment. In the Sierras trying to operate while hiking is a bit
difficult since most of the trails are in fairly steep sided canyons
plus my wife would beat me to death for looking like a dork while we are
on the hiking trail.

Yea, the weight advantage is really only valid if the tuner can be left
at home by using resonant antennas.

You are a bold man. If I had brought a radio on my honeymoon I would
still be "wearing it" someplace on my anatomy.....

and this too...
You are a bold man. If I had brought a radio on my honeymoon I would
still be "wearing it" someplace on my anatomy.....

Hi Rick,

define "dork"... I think "dork" is hiking shorts and full length boots (what
I call my 'hunting boots')... everyone's definition of dork is different.

BOLD? no, my wife is N8LBR, her dad is W8MXR, her brother is WD8PMU - but
the turkey let his wife (err EX wife) convince him to let his license lapse,
and her cousin (our host in Montana, in a meadow along the Gallatin River,
just south a Bozeman). is W6UCR, so you can see how she "understands" the
need to play radio while hiking the boonies along the Gallatin River, or the
Yellowstone River, or the Little Pigeon River... yea, we like rivers, but
only ones that we can see the bottom, hihihi.

Hello all,
Received my Saratoga EZ-PSK and had a contact with Texas from
Michigan today. Very nice, simple, interface. Turned off the speech
compressor, took her down to 5 watts, mic gain at 10, plugged in the
interface and was off and running. Works great. Gentleman gave me a
clean signal report of 599.
Yes, it is connected to the microphone jack...but I'm not interested
in rig control, etc...so it works good for me.
I would like to run a bit more power, but I would imagine running the
rig at full-throttle might not be good for it on the digital modes?

Hi Bev,

In digital modes never run so that you get ALC, otherwise you will have a
dirty signal.

Select the menu option which shows ALC during TX and just make sure you
never see any ALC, that way your signal will be pure.

Rob:

Welcome. I'll give you my version of an answer. There are many good
answers and I'm sure you'll get plenty to choose from.

I am just a couple of months into PSK31 and am still learning. I
purchased a TigerTronics Signalink SL1+ as my interface box. They
provide a cable to connect to the 703's 13- pin ACC connector,
although I built my own cable (on the good advice of this fine group)
after not being happy with the MIC connector setup. If you run with
the ACC cable, operate your 703 in SSB-DATA (USB) mode because it
disconnects your microphone.

I've tried a number of PSK31 software products to run on my 2.8 GHz
Windows XP machine, but have settled on MixW 2.11. Other than two
audio cables to connect the interface box to the computer sound
card, that's all there is to it.

Actually, the interface box circuitry is not very complex and a lot
of folks homebrew it. And there's other good software and interface
boxes out there. I found through experience that the sound card is
not a place to skimp. Your non-motherboard-integrated Soundblaster
should be fine.

Good luck and enjoy. Hope to catch you on PSK31. Don't splatter.

Bev,
I do not know what radio you are using... so I do not know if you have a way
t measure the ALC (my TS-50 could not)... but the easiest way to set up for
PSK31 is to;

set the RF out to maximum, your mic gain at "normal for phone operation"...
I do not use the MIC input, I go in thru the auxiliary in/out bypassing the
mic section. Set the meter for ALC, set the sound card properties for ZERO
audio output gain.

Go into TRANSMIT, and using the sound card properties, adjust the audio
output until you you see any movement on the ALC meter then reduce the
power slightly.

I get about 65 watts on my IC-706mk2g when I do this, then I turn the audio
gain down more until the meter reads about 10 watts.

I can work anyone I hear with 10 watts, most of the time, even less, 3 or 4
watts.
| 1061|1056|2004-02-15 02:15:08|kc8jwa|Re: PSK TODAY - 703|
Hi Rob,
I've been running psk, sstv and rtty for years on my Icom 746. I use
a rigblaster on the 746.
http://westmountainradio.com
What is nice about this unit is you can buy one that allows you to
use your microphone also, especially useful between sending sstv
pictures... and also makes it easier...you are not constantly
removing and putting back your microphone.
For my 703, I just wanted a very simple interface to use for psk, so
I went with the Saratoga EZ-PSK. Go to:
http://www.hamstop.com
Some hams enjoy building their own interfaces that plug into the
plugs in the back of the radio so you don't have to mess with the
microphone. Nice, but not so nice for someone like me who barely
knows how to solder, or cares to. (SORRY!!) I thought most of these
were used for rig control via the computer, but apparently they can
get them to do a number of things such as the digital modes. I did
call about one mentioned earlier on this group that you can buy
already made... but it did not include the capability of psk..it was
strictly more radio control.
Along with one of these interfaces, a good soundcard (which you
have!), all you need to get started is a free soundcard program such
as digipan, mmsstv, mmtty, etc. You can find them free for download
on the internet by just doing a search, like this site:
http://www.muenster.de/~welp/sb.htm
Have fun! The digital modes are great!

| 1062|1056|2004-02-15 04:20:47|Rick Booth|Re: PSK TODAY - 703|
Keep in mind the peak power of the radio is 10 watts. This means that
with certain signal types you can't run the radio at an *average* of 10
watts. 100% AM, for example, has a peak to average ratio of 6 dB so the
radio can only be run at 2.5 watts average. PSK31 runs somewhere around
2 to 3 dB peak to average so 5 watts average is about all you are going
to do.

I am currently the owner of a brand new, unopened Icom 703+
transceiver(S/N: 1501241). I have heard and read in Eham.com and this
thread that the radio does have a few problems such as RF getting
into the keyer, intermittent reduced power output, and the like. Are
these valid problems? Are there other problems in addition to these
that I should be on the lookout for? More importantly, if problems do
exist with this rig, does Icom have any factory modifications
developed to alleviate the situation? Based on the factory
modications available, I am thinking of sending my radio back to Icom
and have them incorporate these modifications(all at one time )into
the unit before I shart "tinkering" with the it.

Your feedback would be much welcomed and apppreciated.

Hi Peter,

One thing that you can count on with the e-ham reviews, folks are
either totally elated or PO'ed with their 703's. My first 703 HF
only failed after just four days. Sent it back to the dealer and got
the 703+ SN 1501211. This unit has worked well for me. If it blows
up I'll get another.

I have just in the last couple of days been working pedestrian
mobile with the rig and a 7ah battery in an Expedetion Pack II. I
have a mount constructed for the MP-1 superantenna that gets the
base up above my head and have had super results.

The failing driver transistors and RF getting into the keying
circuit have been the two common issues that seem to have palgued
this fine little rig so far. The 706 had it's growing pains when it
first came out too and today it's a great rig.

Enjoy your 703+. It's a blast using this little rig to make contacts
all over the country and even a little DX.

I can second Ed's comments with regards to the 703+. My 703+ (s/n 1501126) has been on 24/7 for the last 6 month's or so with no problems what-so-ever. Tuner works excellent! Constant compliments of the voice audio from this little rig. I run the rig at full output most of the time into a G5RV. I would buy again. The rig does have the RF feedback problem on CW, but luckily I'm not on that mode much. I seemed to have cured it by grounding the CW jack to the body ground with a small green wire internally. You take your chances with ANY rig, so enjoy the 703+ and let the cards fall where they may.

I contacted Icom support with my concerns about this radio. I
explained that though mine has been running just fine so far, that
I'm concerned with all the bad reviews about finals/drivers going
out, etc.
They're reply was pretty much, If something goes wrong with your rig,
send it in to Icom and they will take care of it. They gave no hint
of any bad run of parts or updated/replacement troubleshooting parts
for this rig. They gave no hint of anything out of the ordinary
going on.
I agree with the others...I enjoy this rig so much, I will just
continue to use it and enjoy it. If something goes wrong with it, I
will send it in to be fixed.
This radio is perfect for what I need, so I'll be keeping it. They
say talking to plants helps them stay healthy. Maybe I'll try
talking to my radio? "Nice radio", "good friend". Couldn't hurt?:)

Hi All,

Just thought I would update the progress withthe 703+. I have used
it here on the base for quite some time. I ordered an Expedition
Pack II that is supposed to be designed for the 703. The weather
finally got warm enough this past weekend to get everything put
together. I had the MP-1 super antenna stuck down in behind the side
straps of the pack which put the base of the antenna at about hip
pocket level. I had an 11 foot counterpoise connected to the radial
connection point. The rig was powered by a 7 ah SLA battery. I had
high SWR and even made a contact but I didn't push it with the high
SWR.

Thinking that the base of the antenna was too close to the ground I
went to the shop and constructed a mount that would hang on the side
of the pack straps but elevate the base of the antenna to a little
ove 6 feet above ground level. I mounted the antenna on the mount,
connected the counterpoise to the bottom of the mount frame and
tried to match the antenna to an acceptable level. Still high SWR.
Well I thought I have to get this whole apparatus off my back and
see what was going on. With the pack off my back I adjusted the
slider on the MP-1 down a couple of turns on the coil. VIOLA!! 1:1
SWR!!

The rest is history. Over the past 3 days I have made a bunch of
contacts with the 703+ in the pack. I have gotten good signal
reports from all over the country. I love this rig! Hey folks get
out there and enjoy your 703!

reviews. Have you had success on "most" bands? have you found any
limitations with the antenna? I know its REAL important to use the
proper counterpoise with it. I appreciate any further comments!

Take care,

Hello...just received my 703+ today and looks to be a wonderful
radio. I have never worked portable with an HF rig before and am
curious about proper/recommended grounding. If used in the scenario
of having a portable antenna, say small vertical on a tripod with a
couple radials for counterpoise, does the radio itself need to be
grounded to the antenna ground (base)? (single ground wire along with
coax). Or can the radio be left ungrounded with only the coax
between radio and antenna? It looks to me like I don't need the
extra ground wire, BUT, I am not sure and nothing is recommended or
not-recommended in the manual. I appreciate the help! 73 Brian N8AVR
| 1076|1075|2004-02-20 14:22:36|John Oppenheimer|Re: Portability/Grounding|
The extra ground wire from the radio to the base of the antenna is not
needed.

Are your radials going to be above or on the ground? I believe that the
consensus is that more radials are needed if the radials are on the
ground than tuned above ground radials.

On ground radials do not need to be cut to a specific length, only have
a bunch of them as long as possible.

Above ground radials need to be cut to a 1/4 wavelength, or a odd
multiple of 1/4 wavelength.

In all cases, more radials give better performance. Each above ground
radial will provide about a 35 ohm ground return path. Two radials will
have a ground return of 18 ohms, four will have a ground return path of
9 ohms. A vertical antenna has an impedance of about 35 ohms, so having
a low impedance ground return is important. Books seem to recommend four
above ground radials giving a total antenna impedance of about 50 ohms,
~35 + ~9.

Have fun, I got my 703 in October. Take a look at my semi portable
station at http://kn5l.net/qrp/. I have made one change, my antenna is
now an old Butternut vertical so that I can participate in the Fox Hunts
on 40 meters.

be a great radio. I love my 706 and am sure I'll be pleased with

| 1079|1078|2004-02-21 04:03:21|flhtci97|Re: 2 questions? DSP and portability|
Hi Bev,

As for the DSP I'm not an officiando in any respect but I leave it
on for SSB and for digital modes. You will find that if you use a 7
ah battery for instance you will get good longevity as the 703
doesn't consume that much current. Once the voltage drops to less
than 11 volts the rig goes into battery mode (power save mode)and
the display will be dark. If I remember correctly at less than 9
volts the display will flash as the rig turns off and on to let you
know the battery is too low for operation. The rig will decrease
power out to 5 watts max at less than 9.6 volts. A quick tap of the
power button will give you a voltage reading of your power source at
the bottom of the display.

back from Icom with the 60m mod installed.

Al, I have been using the same Radio Shack "black brick" 3A switching power
supply for a few years with the Yaesu 817 and now the Icom 703 with no
problems (or noise) to either rig. That and an extension cord has saved
my gel battery, in various hotels, for when I am set up outside far from
AC power. It was Radio Shack number 22-503. I bought it when they
reduced the price before closing it out.

Their web site now shows a 3A power supply, number 22-504. This one is
listed as 5 lbs so it's not a switching supply, but probably equally
useful for stateside use with 110v power.

The "60m metre mod" is a euphemism for extending the TX frequency
range from 1.6MHz to 60 MHz and I think that Icom are reluctant to
admit this in case they are seen to be encouraging other illegal uses
for their radios. The mod is very easy to do yourself if you have
good eyesight.

Tip for anyone thinking of programming the IC-703 memories from their
PC using the CIV interface.
Each memory channel contains 2 frequencies (for the benefit of
repeater splits) and also 2 modes (LSB,AM,FM,...), 2 sets of CTCSS
tones and 2 filter selections. If you are not using a memory channel
for a repeater, then you have 2 quite separate frequencies and modes.
Selecting a new memory with the switch always selects the 'A'
frequency but you can change to the 'B' frequency by pressing 'SPL'
then 'A/B' the 'SPL' again. For example 1 memory channel can contain
both 3663 MHz USB with narrow filter and also 50.085 MHz FM with TSQL
tones.

Al and the list,

Icom installed the 60 meter mod in my 703 when they fixed the keyer problem.
The tech said that he would add a diode to get the rig to transmit on 60M.
Both items were repaired under warrantywithout charge. I was charged for
return shipping.

I use a Radio Shack 3A supply that is small, lightweight, and
shaped like a brick, about 6" long. It's black and looks like it was
meant to be used with the 703. Sorry, it doesn't have a model number
on it.

I'm just curious. I have talked to IcomAmerica and they claim there
is no 60 meter mod (even though there is the PDF instruction
download on their site). Seaching the archives here, it's unclear
whether anyone has actually had Icom do the mod for them, although
some have done the diode removal version of the mod themselves.

I have a feeling they think if they admit to the mod, that everyone
would be returning their 703s for the free service.

So, my question here is: Has anyone here actually had Icom do the 60
meter mod for them?

Actually, there are two mods for 60m operation. I understand that the
"real" 60m mod involves adding a component (a la KI0KY), whereas the
more popular (read that "easier") mod involves removing a component.
The easy mod opens the transmitter completely, while the other only
opens up the band segment that covers the U.S. 60m allocation. Did I
get that right?

| 1099|1092|2004-02-27 20:32:31|wd9ewk|Re: 60 Meter Mod - Again|
Hi!

You're correct! Icom e-mailed me a PDF file that listed the
part number for that diode, and a photo showing where to install
it for the "official" mod. According to that file, the mod
covers 5.00 to 5.40 MHz, although one of the channels would fall
just outside this range. You can see the PDF at:

http://www.kn5l.net/ic703/IC703-60m_mod.pdf

The "easier" mod, which opens up the transmitter completely,
is done by removing one diode. This mod is documented in
several places on the net, and one of those places is:

http://www.mods.dk/mods.php3?radio=icom&model=ic-703&selectid=2823

Or go to http://www.mods.dk/ and click on Icom along the top
of the window. Then scroll along the left side to find IC-703
and click on that. There is currently only one mod available
for this radio, labeled "IC-703 '60-metre transmit mod,' plus
full transmit HF/6 metre".

On my 703+, I did the "easier" mod, and my radio is still
working well. I have only done brief tests on the 60m channels,
and from those tests I only need a real antenna and I'd do fine
with the 703. With only 10 watts, I won't have to worry about
the power limitation on those channels. :-)

| 1100|1092|2004-02-27 21:04:01|Al Hearn|Re: 60 Meter Mod - Again|
I recently sent my 703 back to Icom because I thought I had an ALC
meter problem (they said it works fine -- I'm still not sure) and
asked them to also do the 60m mod, and to ground the key jack.

Although they told me on the phone after the work had been done that
there was no 60m mod (I knew better but the rep wouldn't argue), I
wanted to check after I received the rig back if maybe they had
sneaked in the mod anyway since there are a couple of cases here in
this group where they have done it. They hadn't. But they did do the
key jack mod.

So, my stratey now is to lurk on the 60m channels for a while and
see if it's worth doing the "unofficial" mod -- removing the diode.

Has anyone ordered the diode and done the "official" mod? What does
the diode cost? Anything to watch out for other than that the diode
is a very small SMD and takes care to solder in?

I did do the "official" mod; it seemed to work well. However, the
dreaded output power problem struck my radio a couple of weeks later,
so it has spent the last four weeks in transit to AES/Icom and back.
Expect to receive it back next week. No indication that the power
problem had any relationship to the mod.

Good luck!

For Sale a Yaesu FL-110 amp in nice condition. An excellent amp for
use with the IC-703. A great addition for mobile or portable
operation.

I purchased this amp last year but did not use it very much as I had
100 watt rig for base operation. It was checked out at a friends shop
when first bought. I remember it putting out over 100 watts on 20
meters into a dummy load, driven with only 5 watts on CW. I don't
have a watt meter so have not measured the actual output under normal
use. The RF sensing Key circuit activates with 1 watt or less.

N2CK has excellent over view of the FL-110 with lots of pictures. The
manual is also available for download.
http://www.qsl.net/n2ckh/fl110.htm

You can see it is very well built, with the proper band pass
filtering.. This is a ham radio amp, not one of those cheap wide band
things made for 11 meters.

Covers 160 - 10 meters (17 meters (15m band position) and 12m (10m
position) and 30 meters (20m position) but output is slightly less.

Input Impedance: 50 ohm

Drive Power: (actual operation test)1 watt or less

Max. Power Input: 200 Watts

Power Requirements: 13.5 Volts +/- 10% - 17 Amps (100 Watts out)
Auto transmit switching with RF sensing (no PTT control line
required) or you can run a PTT cable to your rig.

Comes with a user/service manual with operating and servicing info.
Contains pictures, board layouts and schematics.

$225US plus shipping

After reading some of the reviews on the 703 I guess it's a good unit
to get(which I plan on getting myself). I sent an e-mail to Icom
questioning the "problems" that I've read on some other review sites
but I still have not gotten anything back yet,doubt I ever will...So
is it safe to assume that since the unit has been out for awhile that
the more recent models that have been produced won't have
the "problems" that they had when the first came out?....I know
nothing is perfect but I would hate to hve to send the unit back a
shortly after buying the thing.

If you read the past messages you will find that this has been
covered many times..

I think it is fair to say that most users in this group are very
happy with their IC-703s. Some have had problems, others have not.

I like my IC-703 very much. I bought it replace a FT-817.. Recently,
I sold my IC-746 because I find the IC-703 does most everything I
want it to do.. I even think the receiver and DSP work better. When
the bands get bad an amplifier is nice to have around.

It is not safe to assume that you will get

large places buy huge amounts of a product

There is a diode removal for open TX but also you can add a diode to

Hi Brian,
Icom have their own version of this ant, AH-703. (see my

The one difference I can see is that the Icom version has a spring at

enable a 90-degree "bend" to allow connection to the rig when its sat
on a table etc.

Both antennas cover the same freqs.

Should I connect the ladder line to the radio with a 1:1 or 4:1

Hi group,

Icom says the FL-65 is standard in the 703.

Does this mean that you have to take it out in order to put a different 455KHz filter?

I see from the inside pictures that there is a murata type filter next to a bigger one. I
assume the big one is the 455KHz FL-65, correct?

Thanks.
| 1139|1138|2004-03-15 06:39:09|Al Hearn|Re: Filter question|
The FL-65 is the standard built-in 2.3 kHz SSB/CW filter. There's a
place for one (and ONLY one) more filter to be added - four choices:
either a 1.8 or 3.3 kHz SSB; or 250 or 500 Hz CW. It will also take
a FL-96 (2.8 kHz).

different 455KHz filter?

Wish it wasn't so but it is. There is room for one more "better" filter
so you get to go for decent CW selectivity or improved SSB selectivity.
If you have an CW aspirations with this radio you will need a better cw
filter which means you will be stuck with the normal ceramic filter for ssb.

Hi,
I have tested this set also for broadcast listening, it's very good
set, and you can use also the narrow AM filter, being Murata
CFJ455K4 around 2.5 kHz, for SSB you can use also the additional
filter slot, I have 3.3 Icom's own for it, but unfortunately it's
not possible for AM (not possible for the software reason)

The sensitivity, dynamic range and audio is very good, and you have
DSP autonotch and NR as in Icom R-75. There is MW atteanuator circuit
which might be able to remove? Even the set has built in crystal oven
for highest stability.

I only miss the key pad (available from SWL remotes) and more memories

Ted,

I've had my 703 since July of 03 and to this date haven't found an after market manufacturer of the DC power plug. You could hack the one off and use Powerpoles. I have not yet. The relay chatter is normal. Latching relays are used, similar to the LDG Z11. I just wish that the 703 had the same matching range. I use mine portable on battery so I just shortened the power cable and attached .250 female spade connectors. They match most SLA batteries. I use a commercial Buddipole and am always amazed how the combo works.

Ted,

Yes, the latching relays make a chattering noise when tuning but the
benefit is that they stay latched and don't use power once set.

I gave up looking for the power plug to match Icom's and replaced
mine with a more common variety from Radio Shack. Now I have a
number of power cables for different uses, including one with a cig
lighter plug for field use with a small lead-acid battery power pack.

Hi,

In terms of SSB rx & audio recovery, how does the 703 compare to the tentec argo V?

I am really asking about rx performance only on ssb, audio recovery and receiver
quietness.

I am aware of all the other differences.

Tnx!

OK. tnx for the feedback.

But, numbers do not mean everything..an actual user experience with
good ears is best.

Anyway, looking at the numbers, phase noise and such, the 703 is
superior.

But it still does not tell me how the audio recovery is.

I have an IC-765. Maybe someone can compare both rigs in audio recovery
so that I have an idea based on 765 standards.

Best.

I have a Vector 6 amp supply that I picked up at Target for $20.00
that is intended to be used with their 12 volt travel coolers. It
makes me nervous as I can find no documentation where it specifies
any kind of over-voltage protection with these things. It puts out
12.8 volts according to my DMM. It's a noisy little bugger on the
lower frequencies but not a whole lot of noise from say 10 MHz. on
up but still some noise none the less.

Well my new 703 arrive via UPS this morning. I was busy early but
finally I got it all unpacked to check out. After getting a pwr
supply set up I decided to try it out into a dummyload first.

I have to say I about had heart failure. I was getting no output
either SSB or CW. I think the problem was that I tested the
internal tuner first. After I turned off the tuner I got a full 10
Watts into the dummy load. I still have to try it on the air yet,
but I am looking forward to taking it out with my new Buddypole and
seeing what I can do. I have the 706Mk2G so this is somewhat
famiiar.

I'm not sure why the tuner shut me down so maybe someone can comment.

Looking forward to lots of fun.

| 1160|1158|2004-03-17 06:37:20|Al Hearn|Re: New 703 Arrived Today.|
I would say that, right out of the box, the tuner was simply not
matched to the 50 ohm dummy load, and with a high SWR, shut down the
power to protect the finals. When you turned the tuner off, it
matched to its normal 50 ohm impedance. Turn the tuner back on, hold
the button for 2 seconds until the relays stop chattering, and
you're good to go -- until you hook it up to an antenna. Then tune
again or set to automatically tune.

Just a note to put a cap on my new 703. Finally had time to try it
out this morning. Heard a station in Chicago calling CQ on 18157.5
so I quickly answered is cq. I was rewarded with an instant reply
and signal report of 55. I was using my B&W Folded Dipole up at
40'. I was pleased with the audio that was coming into the shack.
I think I am going to like this little rig. Much better than the
817 I used to have but sold. I never used it on 50,144 or 440 mhz
so won't miss those freqs.

Now as soon as it warms up a little I am heading out to try this rig
with my Buddipole antenna.

Thanks for all the comments.

| 1166|1148|2004-03-19 20:06:02|Mike|Re: Antenna Tuner Noise etc.|
The other guys answered the chattering question. My comments
concern the power cord.

I approached it problem this way. First I attached a set of
Powerpole connectors to the end of the stock cable. Next I created
two extentions for different uses.

One extension terminates with a lighter plug.

The next extension terminates with soldered bare wires for
connecting to a portable 12v pwr supply.

So now I connect to my RigRunner panel, Portable Pwr Station, and
Portable 12v supply. If I find I need another extention I can
easily make it up.

Just another approach.

The weather being nice I took the new 703 and new Buddiepole antenna
out for a portable spin. I set up the antenna in the yard, hooked
up the rig and made a few solid contacts on 17 meters. The antenna
was only about 14' above ground level. Even with that I heard a
station on Cook Island working other stations in the US. The
receiver is super. Can't wait until the weather improves enough to
be out on a regular basis.

I own both and have been using and comparing them for about 6 months.

The ICOM 703 is better in the following ways:

Far more features, especially in scanning modes.
Built in keyer is very good, has three messages instead of the typical 1.

Far lower power consumption, as low as 300 MA on receive. The ARgo draws 2.0 amps on receive, which is the worst of any QRP rig I have ever owned. On transmit, the Argo draws 4 amps for 5 watts out, the IC703 less than 2.0 amps.

IC703 has a much more intuative (to me) menu system. There is no logic whatsoever to the Argo. I rarely refer to the ICOM manual, but keep the Argo manual open most of the time.

The only thing I use the Argo for any more is PSK 31. I have considered getting rid of it.

Well, with no warning at all my IC-703+ quit transmitting. Only in
operation 60 days with maybe less than a dozen actual contacts
made. Did a total reset of the radio and still no output. No
indication on the mic gain setting either which makes sense if
there's no RF being generated. I could hear my signal in a nearby
receiver so I know it was at least generating a small amount of RF.
Probably the bad driver problem I've heard about. SN 1501144. The
dealer who fortunately is local verified the problem and is going to
repair it so hopefully it won't take long. Guess I'll have to go
back to my trusty old Yaesu FT817 which has never let me down. At
least it happened before I took it out on vacation in June is the
good news.

Hi Gary,

Sorry to hear about the demise of your 703 Plus. I'm just curious
what mode you were operating and any of the other details. My first
703 went south after 4 days of operation. I was on PSK and may have
been getting a bit windy on the transmissions so the driver may have
failed due to heat.

It seemed that the Plus models were fairing better than the HF only
models. I have SN 1501211 and it has hung in there so far. Like Tom

Sorry about the failure.

I've been following most of the threads about these failures since
before I bought my 703 late last year and don't really see any
patterns regarding mode, power, or other settings.

I've been operating mine on PSK and SSB at full power with no
problems. Actually, I prefer to force the problem to occur, if it's
going to happen, so that I can get past it. If the radio won't
operate at rated power, then it must be fixed. I don't feel I should
operate at reduced power to try to avoid what shouldn't happen. But,
so far, no problem (Serial #1802589).

Ed,

The rig had been sitting on the desk turned on all morning. I had been
tuning around listening and heard a special event station on 17 meters SSB
and picked up the mic to give him a call. No warning or anything on the
output power. Simply nothing coming out the back and no mic gain either.
Checked other modes like AM and FM and still nothing. Did a total reset to
be sure I had not accidentally set some parameter incorrectly and still
nothing out. I'm hoping it's the driver that went so I can eliminate that
as a questionable item in the future. As you say, when that is the problem
and it's fixed, it tends to stay fixed. I hopefully will have found the
weak link in the radio at that point.

I'll know more when I get the rig back in a few days, weeks or months. :-))

It's probably the driver. The 817's have had similar problems with
finals failing.

Mine quit about a month after I got it. It was used in the car on a
daily basis as a burning-in exercise. Like yours, mine went to zero
output with no warning. I did get a little intermittent output for a
few minutes the next day, but it quit for good after that. Round trip
to Icom and back was a little less than three weeks (including the
Thanksgiving holiday) -- not too bad -- but I understand that
turnaround times have varied depending on backlog at the shop. It's
worked fine for four months worth of daily use since then.

My Argonaut V is incredible. Quiet receiver, excellent filters built
right into the rig and smooth as silk QSK - no old technology
mechanical relay either - totally solid state switching between
transmit and receive. I've run the Argo on all digital modes, CW and
SSB. It performs flawlessly. Receiver is like listening to a fine
stereo system. Formware can be updated by the user. Little higher
price than the 703 out of the box, but when you start paying for all
the extras needed by the 703 (filters) the Argo comes out on top. The
only thing the Argo does not have is a built in tuner and 6 meters.
But for a QRP HF rig, it ranks up near the top.

QST and other lab reports mean nothing compared to actual on the air
experience. When the 703 was next to the Argo, again, no comparison
in my experience. The Argo could tune out the interence with ease,
while the 703 could not. This was especially noticable with a CW
contest and with the digital modes, particularly PSK.

The mechanical relay that I was referring to is versus solid state
switching between transmit and receive - not for switching band pass
filters. Mechanical may be superior in that instance, but it is not
superior for switching between the transmit and receive function. Not
an apples to apples comparison. The Japanese still can't make a real
QSK rig - they always seem to use a mechanical relay.

One final remark about the Argo, the 703 and even the FT817 - you
don't hear about constant failure of the finals with the Argo. In
fact, I have never read a report of failure of the finals on an Argo.
I read final failure reports all the time with the 703 and the 817.

I still have the 817 and kept the Argo instead of the 703.

the same thing. Guys always talking about having to replace the
finals. When I owned a SGC (a rig I liked but it had no features,
not even a band change button!) it had a different problem and mine
quit receiving! So no matter what QRP rig you buy there is a chance
it will crap out. Unless you wanna build your own K2. Then you
can't blame the manufacturer.

Hi all,

As I start to put my big toe into QRP/portable work, I thought I'd
investigate antennas first. Does anyone here have any experience with
Yaesu's ATAS-25 antenna or the QuickSilver Minute Man 20 antenna.

I'm looking for a simple, quick-to-setup antenna to use as a portable

Hello Edward and the group,

I am posting this for all to see and perhaps to answer your questions
Edward. The ATAS does not cover the 80 and 60 meter bands, but the
MFJ does as you will see in the posting.

Well, I've seen it since the 2004 catalog was released. I decided to
purchase on (model MFJ-1664 80 thru 10 meter manual screwdriver
antenna). It arrived via UPS yesterday and I was able finally today
to get outside and play with it a bit. I used my chaing link fence
around the backyard to bolt it to and as a counterpoise. I also
attached some tuned radials just to be sure. First I used my MFJ
antenna analyzer to check it for bandwidth and make some rough
adjustment markings for field use. I did have to make an impedance
matching coil to get it to tune 40/60/80 meters. The coil was 12
turns, #14 enameled wire, 1/2" OD (this is approximate and anything
close will work for you). The antenna tuned every band with SWR of
1.2 or less. 40 meters and above I was able to cover the entire bands
by tuning for center band, 60 meters I had to tune on a per channel
basis (or use the internal tuner in the 703) and on 80 meters the
bandwidth was really narrow, only about 25 KHz, but this was to be
expected. Also I was using the long 10 foot supplied telescoping
whip. The antenna will tune 60 meters to 10 meters with the supplied
4 foot whip but bandwidth was much more narrow and effeciency was way
down using the 'by ear' method.

Of course, every setup will be different, but in general I would have
to say the antenna is a good buy for the money ($149.98 shipped to my
door). It is well constructed using all aluminum and stainless steel
(other than the PVC coil form and end caps and copper fingerstock to
contact the coil). The antenna tuned easily, was not affected by body
capacitance (only slighty, but not enough to cause tuning problems)
appears to be rugged enough for portable use (time will tell) and is
lightweight for same. The long whip is the least durable item and can
be broken if care is not taken, but you are warned of this in the
instructions.

I made contacts on 17 meters, CO8LY in Cuba, J69AN in St. Lucia, 2
stations in SC that I talk to regularly on 40 meters and less than
100 miles away at 5 pm, 3 stations on 60 meters, KA8JIL in Ohio,
WB3KDB Maryland and a local 2 miles away. I was using my Icom IC-703
at 10 watts in the back yard on battery power. All stations were 59
plus on receive and I was given 59, 51, 59, 59, 57, 59 and 59 plus
respectively from those stations. An I happy with the antenna? Yes at
this time, but time will tell as to overall satifaction. can I or
would I recommend it? Well depends, not for mobile use, not for
pedestrial portable or bike mobile unless you use something other
than the telescoping long whip or perhaps the short whip (not sure
how durable it might be either). For fixed location portable or
campsite or emergency field location operation? You bet I would
recommend it. I think it will give you a good bang for the buck. It
is no more expensive than many other antennas in use and I think this
one will give better performance compared to most of then in the same
steup. It also offers the easy storage, easy portability, easy setup
features most of us look for and in most cases is less expensive than
many competing antennas.

Just my humble experiences with this antenna and I thought I would
share them with everyone.

Johnny, a very interesting summary of the MFJ-1664

Some comments, and using the group to check my understanding.

You noted that 40M had a low SWR across the band. The wide bandwidth is
probably caused by a very high series resistance in the antenna giving a
low Q.

An antenna is a series resonant circuit, The Q of a series resonant
circuit is proportional to 1/R. Big series resistor, low Q, wide
bandwidth, low efficiency.

The lowest Q antenna is a 50 ohm resistor ;-)

As an experiment, you may want to try some (more) 40M tuned radials.
Each tuned radial will supply a ground return of about 35 ohms. A short
vertical antenna has a very low impedance, below 35 ohms, so it is
important to provide a good ground.

What I have always wanted to know is, can the antenna R and or Q be
calculated by measuring a SWR bandwidth. Or, can the equivalent 3 db
resonant bandwidth be calculated from a SWR bandwidth?

Another portable antenna alternative is a collapsible fiberglass pole, I
purchased 22' pole from "Into The Wind"
http://www.intothewind.com/cgi-bin/detail.cgi?itemnum=9634&sql=all Very
nice! it can support a vertical wire of any length to 22' But then the
wire, ground, and any other tuned circuits are still required. But, with
22' an frequency above 20 meters can be used without any extra tunning
circuits.

Edward,

I don't know how much money you have, but you can build a bugcatcher
antenna for a probably 20 bucks!!! All you need is a slinky, some
1/2" pvc, and some aluminum rod. For the top part of the antenna I
used the w3ff collapsible antenna sections for the buddipole. I used
about half of the slinky and used grommet strips to stablize and
separate the coil turns. Use some wire and an aligator clips to jump
the turns to tune the antenna or purchase the extra buddipole clips
and a minibanana clip. you can go to n1lo and the pac-12 websites for
ideas to build it. pictures of my antenna can be seen on the hfpack2
yahoogroup.

Hello John,

No, you made an assumption where I did not explain clearly. The SWR
across 40 meters is adjustable to the point that it is 2:1 or less across
the majority of the band. It did rise over 2:1 at the bottom or top
depending on which end I was interested in. I could tune it for a center low
and use the tuner in the 703 to bring it down at either end. As a broadcast
engineer I am aware of the characteristics of a 1/4 wave vertical antenna.
The MFJ behaved just as it should. As I went lower in frequency, the
bandwidth (usable between 2 points) decreased as it should have. I not only
had the antenna attached to the chain link fence, but also had attached a
number of 1/4 wave radials for each band since I wanted as best a test setup
as I could put together easily. I would speculate that the MFJ is as
efficient as any other similar antenna of its type with similar Q
characteristics. It diffidently outperforms any of the other portable
antennas I played with over the years except a full size cut to frequency
dipole. The full size dipole however, as you go lower in frequency becomes
less easily installed or portable compared to the MFJ.

Last month I decided it is time to get serious about QRP. After
considerable thought I purchased the 703 with a Heil Traveler. Just
for the trial run, I hooked the rig up to an old G5RV under the eves
of my home (about 12' above ground level). The result: 5-7 reports
and GREAT reception.

With spring arriving in ND it is time to field and mobile test this
little radio . . .

Oops, I missed the tune antenna to center, then additional tuning with
rig tuner.

I was using my 703 with a 20 meter ground plane vertical with four tuned
radials, but found that the 703 could tune to it on all bands, including
80 and 40. What I think was really going on was that on the other bands,
especially 80, the antenna configuration was not much more than a
resistor ;-)

I have replaced the 20 meter vertical what an old Butternut HF V5
vertical with extra 40/15 meter radials. Works much better. But not very
portable!

I can suggest the SuperAntenna MP-1 as one to consider. Although
I've had mine only a short while and haven't fully tested it out yet
with my 703, it seems to work as advertised and a lot of folks seem
to like it (see reviews on eHam.com). I'm impressed with it's
quality and portability. Setup is a snap.

I also like the fact that it is very modular and can be easily
reconfigured in a number of different ways to meet different needs.
Everything breaks down and screws together with standard 3/8x24
connections, even the (optional) tripod base. For example, I have
two different lengths (8.5' and 36") of base sections, plus a
coupler to combine the sections if desired. Also have two different
whip lengths, 44" and 120" and an alternate counterpoise system.

- i have used a 17M Lakeview hamstick (about $25) clamped in a mount
to a metal picnic table...

- the 703 was able to tune the hamstick on 17M and 20M... worked great!

- even better, i use the Lakeview dipole mount w/2 hamsticks clamped
to the top of an SD-20 crappie pole and some coax... works great and
the whole setup cost about $80...

I sure liked the 2 hamstick arrangement, but must ask, what's a "SD-20
crappie stick"? Also, where do I find Lakeview hamsticks

Hi there. I have been having the same enjoyment with the 703. I've
got a beautiful 746Pro sitting there, and I swear I have more fun on
the 703+..Two days ago I hit Diego Garcia on 17M with 5 watts, and
yesterday I hit the Netherlands with 8 watts. Its really quite
remarkable how well QRP works :) I've also been having a blast
playing with and making up different antenna configurations for the
unit. I've had great luck with 9.6v battery packs and a 20-6M dipole
on a 30' portable mast :) Have fun with the radio and maybe we'll
catch you on the air!

I also liked my IC-703 so much that I stopped using my IC-746.. Last
week I sold the 746 and don't miss it at all.

I admit to not running QRP all the time. I bought a HLA 150 amplifier
for those time when 10 watts isn't quite enough. (especially on the
low bands)

| 1201|1194|2004-03-25 18:31:33|dietmarfichter|Great Fun that QRP|
I echo Brian's comments. Also have a 746PRO along with an 756 but
the 703+ gets the work out, great receiver. I acquired the 703
because I really enjoy operating QRP during field day and in the
past the IC-756 bas been the work horse for this event. However,
this radio is big and draws 7 amps at 5 watts where the 703 is small
and only requires 2 amps for the same power. Much easier on the deep
cycle battery.

This year for the 2004 field day outing I will be operating
exclusivley PSK31 digital and QRP of course. Also, wanted some
directivity and antenna gain this year so the 703+ will be coupled
to my new homebrewed 20 meter ham stick mini-beam mounted on top of
a 21 foot fiberglass Wonder Pole. Hope to see some 703 waterfalss on
my screen.

Hi all,

sometimes my IC-703 fails to power-on. (NO effect whatsoever after
having pressed the [power] switch.!

Remedy: disconnecting / connecting the power cable several times.
Suddenly the radio will power on...

Anybody having an idea about what's going on.?

(My radio is brand-new)

Thanks and best regards,

Nick / HB9DRX
| 1203|1202|2004-03-26 01:23:52|MIKE BRYCE|Re: IC-703 power-on failure|
try resetting the control head from the body of the radio.

a small spray of deoxit would be a good ideal too.

my brand new unit did the same thing too..
