I'm looking for a list of currently sold new radios that will give us full duplex capability on the FM birds. I'd prefer an HT, but interested in mobile platforms as well.
For HTs in current production that will work all current FM satellites full-duplex, there is only one: Kenwood TH-D72A. This radio appears to be on the path to being discontinued by Kenwood, so you might want to get one sooner rather than later. Kenwood's new TH-D74A HT, a triband 2m/222/70cm HT, is not capable of full-duplex operation.
There are some Chinese-made HTs that will work the "U/V" FM satellites (70cm uplink, 2m downlink) like AO-85 and other upcoming Fox-1 FM satellites full-duplex, but not the "V/U" FM satellites (2m uplink, 70cm downlink) like SO-50 and LilacSat-2: Wouxun KG-UV8D and KG-UV9D. It appears that derivatives of these radios like the KG-UV8E, KG-UV8T, and KG-UV9D Plus will also work the "U/V" FM satellites full-duplex. The main issue with these HTs, like with a few others, is that transmitting on 2m will desense the 70cm receiver. The 70cm amateur satellite subband at 435-438 MHz is almost a perfect 3rd harmonic from the 2m satellite subband at 145.8-146.0 MHz - especially with SO-50.
Mobiles... more options. Icom IC-2730A, Kenwood TM-D710 and TM-V71, a couple from Yaesu (FT-8800R, FT-8900R), and the Alinco DR-635. I have not tried some of the newer Icom and Yaesu mobiles with their respective digital voice modes, so I don't know if the Icom ID-5100 or the Yaesu FTM-100DR or FTM-400DR are capable of full-duplex operation on any of the FM satellites. Same with Alinco's new DR-735. I have not tried any of the Chinese-made multi-band FM mobile radios, so I can't offer any information on those radios.
The following link is from 2009, with a long list of older (and almost all discontinued) HTs and mobile radios capable of working FM satellites full-duplex:http://web.archive.org/web/20090724094403/http://www.thathamkid.com/website/ham-radio/full-duplex-radios
The original page is no longer on its web server, but the Wayback Machine picked it up and still has it.
If all else fails, you can use a pair of HTs to make a station capable of full-duplex FM satellite operation. Some have used a pair of the inexpensive Baofeng HTs to do this, or use a Baofeng with an Icom/Kenwood/Yaesu HT not capable of full-duplex operation to make a station ready for full-duplex operation. Whether with one HT, 2 HTs, or a dual-band mobile radio, make sure to use an earpiece or headphones to keep your receive audio from feeding back into the microphone.
Good luck, and 73!
