On your 'D72a and the FM birds ...

-Use VFO B for TX -VFO A for RX (it has better sensitivity) -balanced audio all the way to VFO A -open squelch for VFO A -5W transmit

From another post ...

Another thing that's handy for the TH-d72 is the M>V key. Put the center freq in memory, but before the pass copy it into the VFO for Doppler tuning. Saves having a lot of memories used for Doppler shift and the TX frequency isn't as likely to need big adjustments thanks to the capture effect on the satellite receiver.
