Update based on 18:50 pass
A keyed carrier goes through the transponder.
With both RX and TX Doppler shifting, Carrier Downlink shifts upward in
frequency at a rate faster than Doppler shift.

Was able to hear my carrier thru the Turksat transponder on 17:20 pass at
Behavior was strange, almost behaved like it wasnt inverting (it is
inverting, correct ?).
SSB did not come through cleanly.
TX/RX offset varied during the pass.
I will be better prepared for 18:49 pass and get some panadapter screen
May also try BUGCUBE that pass
