As Dave KB1PVH said, the answer is "no". The TH-D74 is not capable
of cross-band full-duplex operation for working FM satellites,
unlike the older TH-D72 which can do that. When you transmit from
one VFO or "band" on the TH-D74, the other VFO/"band" is muted.
I have written a bit about how I have used my TH-D74A on satellites,
and not just trying to use it with FM satellites, on the QRZ.com
satellite forum at:
I have used my TH-D74A on both SO-50 and AO-85 in FM, as the
downlink receiver when working SSB satellites like AO-73, FO-29,
and XW-2F (transmit radio was a Yaesu FT-817ND), and working
the orbiting packet digipeaters on the ISS (previously on 145.825
MHz, and now on 437.550 MHz) and NO-84 (when available).
Please e-mail me directly if I can be of further assistance with
the TH-D74A on satellites.
