I'm working with a university that is launching a UHF half duplex satellite in a few months and is putting a ground station at U Alaska Fairbanks. We are planning on a TS2000 for the radio. I've not seen any new ones pop up lately but thought I'd ask if that one is still a good choice. Seems considerable overkill for a single UHF freq with 9k6 GMSK modulation.

The TS2k handles full-duplex which you do not need. It also has some an unfortunate birdie which may or not affect you (436.7950). You could easily use some other UHF receiver or receiver chain with some work. Notably you may have to remove the de-emphasis circuit or bypass it by tapping into the discriminator directly; Some radios provide such already and then you could easily decode 9k6 GMSK in software.
