[amsat-bb] Rotor control with SatPC32ISS

[Stefan Wagener]

Not sure what these generic statements are based on:

*...."but ICOM and some other radios do not really fully support it and
sometimes the tx frequency ends up being written to the RX."... *

..."The ISS version has some quirks particularly if you are only using one
radio, as many radios work a bit weird when sending remote frequencies for
same band split."

Using *one* Icom radio (IC-9100) in *split mode* with SatPC32 ISS works
just beautiful. Never had problems with doppler control and direct contact
with the ISS (school and astronauts) during many contacts and APRS (when it
was operational!).
