Bill,
Full computer doppler control is preferred, but if it isn't possible, tune
the higher of the two frequencies. Check out this link for the One true

I tune both using SATPC32 or HRD SATtracker.
You may not need a satellite mode if you use software.
I've been running across many more folks that tune both these days.
It definitely makes for a less chaotic passband without folks drifting
through the passband.
Rule of thumb is that
Hi Bill,
Take a look at this, still the best info:

You always receive USB but may need to Tx LSB

Having been a ham for over fifty years and having worked most modes of
operation, including chasing DX and even satellite back in 1979, I totally

on AO-51 is bad, try working a rare dx expedition sometime. Talk
