Hi Mike,

Consider these:

-Full Duplex is receiving and transmitting at the same time, typically on
different frequencies (bands).

-When working satellites in this mode, you are doing the same thing as their
transponder is :-)

-When you hear your / another signal in the receiver, presuming it and the
transmitter are tuned to the right frequencies, it represents what you or
other stations are transmitting to the satellite.

Does that help?
