Clint,
Thank you for your positive contribution to this discussion thread with your question. As you know, the list of radios currently in production that support full-duplex operation on FM satellites (going from KE9V's original message) would be short. If we limit the list to those able to work SO-50 full-duplex, transmitting on 2m while simultaneously receiving on 70cm, there is one HT:
Kenwood TH-D72A
a few dual-band FM mobile radios:
Yaesu: FT-8800, FT-8900 (I haven't tried the newer FTM-350/400 yet)
Kenwood: TM-D710, TM-V71
Icom: IC-2730A, IC-2820H (I haven't tried the ID-5100 yet, and Icom America still lists the IC-2820H - a radio I use on FM satellites)
Alinco: DR-635 (I haven't tried the DR-638 yet)
and the two satellite-ready base transceivers:
Icom IC-9100 Kenwood TS-2000
This doesn't include using two radios to make a station capable of full-duplex operation on SO-50. I have not tried any of the 2m/70cm FM mobile transceivers that are coming from China, and - as far as I know - I have not seen any reports of those radios being able to work SO-50 full-duplex.
Not all of the rigs listed in other posts are "20-year-old ancient rigs", as you characterized them. Some came on the amateur market after 1995, but yes - they are no longer in production. Since many of these radios are still considered good performers on SO-50, why not include them in the discussion?
Andrew KE5GDB took a stab at compiling a list back in 2009. His web site no longer has that page, but the Wayback Machine cached a copy of it from back then:

Other radios, in particular HTs like the Wouxun KG-UV8D in current production, and many others like newer versions of the Icom IC-W32A that have gone out of production, should work fine with the upcoming Fox-1 satellites that use a 70cm uplink and 2m downlink - reversing the uplink and downlink bands as used with SO-50.
73!

I can give [bad] references on the Baofeng UV-5R HT...
On receive with some as simple as a moxon on top of the HT the SO-50 is clear and loud as long your hand can turn to match polarization.
But, as soon you key the PTT on ANY rig on 2m near this tiny HT goes overloaded, no matter if you use a diplexer or a LPF with at least 30dB att. on 70cm...
But, maybe on Fox sat series...
I feel I need to make this clear... to others not to put his "eggs on that basket"

Hola Pavel!
Thanks for your post. I did not mention any of the Chinese-made HTs like the Baofeng UV-5R earlier, since they are not capable of full-duplex operation on SO-50. Unfortunately, not all UV-5Rs are the same. I have used one of mine as the downlink receiver, when connected through a diplexer to my Elk log periodic. I have transmitted with another UV-5R, a Baofeng UV-82, and even a Wouxun KG-UV8D.
Last year, I did a demonstration on SO-50 using two Baofeng HTs (UV-82 for the uplink, UV-5R for the downlink) connected to a diplexer and my Elk antenna. This worked OK, and I made the satellite audio into a slideshow video I posted on YouTube:

I have not tried any of my Baofeng or Wouxun HTs with an Arrow Yagi, or a homebrew equivalent of that Yagi.
I know a friend who has ordered the new AnyTone Termn-8R 2m/70cm FM HT, which is being promoted as capable of full- duplex operation. It may be like the Wouxun KG-UV8D, which has been promoted the same way, but cannot work full-duplex with the weak SO-50 downlink. I hope to get a chance to try that new AnyTone radio soon, to see if it does any better on SO-50 than the KG-UV8D.
Buen fin de semana, y 73!
