Dan,
Thanks for uploading the paper, very helpful. Guess no one rig can please everyone, but what is it about the FT-530 that makes it "very awkward to operate"? Drew KO4MA gave the FT-530 high praise in his post.
I could never hear my downlink on the IC-W32A I borrowed for Swan Island, and if you can't use it to work full duplex, might as well buy a brand new FT-60 for about the same price as the W32A sells for on eBay. Also, you can't work the ISS with an unmodified W32A, as it won't transmit below 440 mhz.
I know it's possible to hear your downlink on the FM birds with some rigs, because many have written about it. I've had no luck with 3 different rigs, even with separate radios and separate antennas. No problem for me to work duplex on AO-7 and VO-52, must be the third harmonic that is the issue with AO-51, AO-27, and SO-50.
A lot of folks seem to like the Kenwood TH-D7A, but the price tag is quite high for a radio that is "very delicate," "extremely difficult to program," and "poor battery life".
73, Bill NZ5N

I have been using FT530 for many years but on satellite for the last 12 months. is really easy to use once you have channels programed for both VFO's. you only move VFO B (UHF) for doppler tracking and back to VFO for Tx. has two volume/Squelch knob's and is excellent for full duplex operation....

A lot of folks seem to like the Kenwood TH-D7A, but the price tag is quite high for a radio that is "very delicate," "extremely difficult to program," and "poor battery life".
I donno. I've drop kicked mine a number of times. It is trivial to program either with the TEXT menus, and full 4-way joy stick, or the PC program. Poor battery life only if you have evrything running to the max:
1) Both internal radios on 2) Internal TNC on 3) Battery saver off 4) Transmitting APRS beacons evey minute at high power
But then that's why most people bought the radio to do all those things..
I agree with Bob. Mine's been banged around more than a little bit, and keeps working just fine. As far as the battery life "issue", I bought a replacement PB39 100mAH NiMH pack from the NiCd Lady for $45, and it lasts quite a while. I'm very satisfied with it. Jim KQ6EA

I've been using a VX-150 and FT-470 and it has been working well. I haven't tried duplex with the 470. It's a quirky hamfest bargain.
To replace my handhelds, I'd wonder about the best mobiles for sats -- a little more oomph when necessary, larger display and controls -- that would serve well as a solar-powered portable. But that's probably another thread.

When I owned a TH-D7A I never ran all that stuff, I guess. But it seems that you can run it on an external power source. That might be clumbersome if out "waving" an Arrow but when used with a mobile or home antenna system: "where's the problem?"
I think the attributes and mutliple uses for the little Kenwood overshaddows any shortcomings. I would have kept mine but the ham I bought it from (at an excellent price) needed it back to donate to a special program.
Some day I may get another. I have use of a Motorola HT-1250 (from work) for general FM use, and I normally use the FT-847 in the shack for satellites, so no immediate need. I have thought that a D700 would be nice for mobile. I still have my FT-817 for multi-modes going mobile or portable. With experience one can work the Leo's without full duplex, though it is much more satisfying to run full duplex for any satellite.

An unmodified W32A transmits on both 70cm and 2m, it should be fine for working ISS: http://www.mock.com/icw32ae_manual.pdf
It's kind of a cool full duplex radio that you don't really see anymore. It has 2 VHF receivers, 2 UHF receivers, 1 VHF transmitter, and 1 UHF transmitter that all tune independently, so it's quite flexible. I've had mine for 10-years now and I haven't found something to replace it.
