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.
