THE ICOM IC-703 QRP

HF HAM RADIO

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.
