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 downlink is USB
Uplink is LSB for inverting transponders AO7b,FO-29,VO-52
          USB for non-inverting AO7a

Its been a while and I need to be refreshed.  When using the sats linear
transponders how does the transmit receive work.

Does the transmit stay on frequency and tune the receiver for best receive,
or does the receiver stay and transmit frequency changes for best receive.
Or do both move if your rig supports a satellite mode.

Also I am hearing what I believe is both USB and LSB on the birds.  Is one
sideband considered to be standard.
