The ICOM 1271A is a nice rig. All mode, and it covers all of the 23cm band. I have one, and have made contacts through AO-51 barefoot with an 18-turn helix. Sounded like I had a full quieting signal. No luck through ISS last night, but I expect it's at least partly because my antenna is the wrong polarization.
The only problem with the 1271 is that you need a couple of other modules in order to get any sort of computer control over it, and they're probably scarcer than the rig itself. Working AO-51 with manual tuning isn't too bad, but it keeps you busy. One hand on the knob, one on the PTT, and one eye on the Doppler readout from the computer.
If anybody has a Yaesu 736R 1.2 ghz module (or even the whole rig, with 1.2 included), I'd really like to work out some sort of trade. The 736R has its quirks and is a bit on the old side, but it's worked well for me. There's no terrestrial 23cm activity accessible from my location (in a bit of a hole), so satellites are what it's all about, and I'd like to simplify and automate where I can.
