Hello all.
I was on one of the early apsses of FO-29 this morning and was having a QSO with another ham about which frequency to tune for doppler. Both of us went LOS without comming to a mutual agreement on this.
This question has been asked before, I'm sure, but I thought that I would ask it again.
Exactly and at numerous time but there was no consensus or agreement on that matter. Even if you tune both the uplink and the downlink automatically you ended up with some manual correction at some point in the pass and you should have your other party correcting both ways also and all the other users on the transponder (read nearly impossible to achieve).
What i found here is to try to tune the downlink only don't touch your uplink at all. I know it's not perfect but it is manageable and even if again we can not expect all of us to use the same method it is a lesser problem then trying to run after each other .
Again it is what i found to be my best way to compensate for doppler shifting but when you enter into a QSO with a station who track both side it is a mess and i was rarely able to complete a QSO as i loose it on the transponder. Let say there is some very bad combination .
