Re: [amsat-bb] Tuning conundrum

[K5OE@xxxxxxx]

Right or wrong, good or bad, here is what I observe (most often) on the 
various analog sats:

Mode J (V/U) birds:
FO-20/29:   fixed transmit, downlink drifts down during the QSO
AO-27:      ditto, but then you have no choice

Mode B (U/V) birds:
AO-10:      fixed receive, adjust transmit to maintain same freq. (difficult 
at perigee)
SO-35       ditto, but then you have no choice

Mode A birds:
RS-15:      adjust the transmit to maintain same freq.

Mixed mode birds:
RS-12/13:   mode K (H/H) ops fix the transmit, mode A (V/H) ops adjust the 
transmit
P3D:        if mulitple uplinks and downlinks are on simultaneously, this 
could be a mess.
