On a whim (and
because I love a good deal), I bought this from Burghardt radio
for $399 plus shipping. The radio arrived fairly quickly and
I hooked it up to my test station. This was a "stock"/NIB
radio, thus with no modifications.

Now
for the REVIEW!
First
of all, I haven't owned this very long, but I did peruse the
703 Yahoo Group and read about the sporatic problems with driver
failures, and (from the words of an Icom Tech) a way to avoid
it! This seemed to beat the FT817 (another model I was looking
at) where the 817 Yahoo group has come up with a group within
the group called the "BFC" (Blown Finals Club).
Following
the instructions I checked the voltage across the designated
resistor and found it to be, indeed, high (almost .7v). The adjustment
to .5 (or close to it) was done in seconds, and a few minutes
later the cover was back on the rig!
As you
can see, this radio looks just like the IC-706, but it only puts
out a maximum of 10 watts. So why would I want this one? Well......I
like QRP. I like CW. I also like QRP CW!! and of course - the
price was right. I was also excited about my plans to upgrade
to General (just need the written test) and also, getting back
onto 6 meters this fall ( I just can't decide whether or not
to get the beam or just the Ringo).
Having
previously owned the quirky FT-100, I was well prepared for navigating
the menu's and I found the Menu's and Operation Guide very easy.
My choice of power supply was of all things the PS/Spkr made
to match the 10m Emperor TS-5010. The color scheme matched and
the 703 sits perfectly on top of it.
EARLY
OBSERVATIONS:
The IC-703
seems to be well built, and for now, it's a really cool rig to
own. However, I didn't like a few things:
1. The
connector for the DC PS seemed a bit iffy so we'll have to see
how it holds up. And...
2. I don't
like the microphone connection at the bottom of the rig. If this
is the way they want it, they should have made the "Feet"
a tad taller so that the microphone connector didn't bind so
much.
3. The
Noise Blanker was much better than my previous HF/6m rig (Alinco
DX-70) but it could have been better.
Well,
there you have it - my min-review of the Icom IC-703. I'll try
and put an update in my Dec or Jan column just to let you know
how the first 6 months went. |
