The manual does not explain satellite ops because essentially it wont do
it. Actually you can (and people have), but it will only sort of
operate satellite. There is no way to set a memory channel for transmit
on one band and receive on the other. You can set transmit frequencies
in one set of memories and receive frequencies in another set of memores
and then transmit on one band and receive on the other. For example set
up the radio as follows:
Program 5 channels with downlink frequency (with various doppler
corrections) and a 6th channel with the uplink. So for example, use
these channels:
300 145.920 67Hz PL Echo up
301 435.290 Echo Dn1
302 435.295 Echo Dn2
303 435.300 Echo Dn3
304 435.305 Echo Dn4
305 435.310 Echo Dn5
Set the radio to the "A" band and select channel 301. Then set the
radio to the "B" band and select channel 300. As doppler changes,
switch bands, change the channel and switch back. Rather cumbesome, but
possible.
