Modern Equipment Matrix
For portable work on the FM birds, there are some wonderful, long-discontinued full-duplex HTs that many are using, like the early models of the Icom IC-W32a, Kenwood TH-D7 and TH-D79, and Yaesu’s FT-470/FT-51/FT-530 models.
The only currently manufactured HT that works well in U/V and V/U mode is the Kenwood TH-D72a - at about US$450.
For the FM voice LEOs (as well as the ISS packet and SSTV), many are using their "primary" HT, and purchasing a less-expensive rig for receive - in order to work full duplex.
Heck, two Yaesu FT-60R radios PLUS an Arrow Sat antenna cost the same at the TH-D72a all by itself ... (grin).

The IC-W2A is also full duplex. Mine's 25 years old and works great with an Arrow.

The Icom W31AT is also full duplex, an earlier version of the W32A.
Others that I think might be full duplex, but can't be sure would include:
Alinco DJG5T, DJ560, DJ580, DJ582 Icom W21AT, Ic32AT Kenwood TH75, TH77, TH78 Probably several Standard Models, I am not familiar with those
The Kenwood TH79 is probably one of the best looking HTs ever made, right up there with the Standard C156A

Kenwood TM-733A is still available on the used market and is full duplex with seperate antenna connectors. I have nade SAT contacts from my car with this radio and can hear myself on the SAT, I still have a couple of these radios still working after 30 years.

Another mobile FM rig to look for is the TM-V7A. They are full duplex, and work well for FM ops. They did have a problem with the display, which began to fail within a couple of years. If you see one and the display is legible, it has almost certainly been repaired by Kenwood.

I will second the suggestion of the Kenwood TM-V7A. I had one for a while and it did well on the satellites, a very sensitive receiver. Another one which is good for the Mode J satellites is the Kenwood TM-251A. It is a 2m transceiver with UHF receive. Has one of the most sensitive receivers on UHF ever tested in the QST product reviews. Heard the FM satellites very well.
