audio offset, i.e. the effective transmit frequency, to the received
audio offset.

OK; that's an important piece of information. I had simply assumed that
the generated audio would be at some fixed frequency.

Thanks.

Digital QSO's normally take place on the same frequency for both sides, so
the transmitter audio offset has to match the receiver audio offset for it
to work.

This is typically done automatically by the software for you. Your
audio will be at the same tone as the receive if you are clicked onto
the receive waterfall, which you would be in order to receive the
station's data. So, no changes in transmitter or software will be needed.

Of all the signals in the receive passband, you need to select one to deal
with.When you do that, every program I've seen so far sets the transmit audiooffset, i.e. the effective transmit frequency, to the received audio
offset.Assuming of course that both xmit and rcv VFO's are on the same frequency.This is typically done automatically by the software for you. Your
