I am new to the satellites. Got to where I can hear my downlink if the bird is higher than 15 degrees. My question is about handling the doppler shift.
If you do not have a sat program automatically correcting you rig frequency, what is the most common or preffered technique? 1 - Hold the TX steady and adj the RX for doppler or 2- Hold the RX steady and adjust the TX for doppler? I know this must be a basic question but I am learning. Thanks,

Hi!
Good question.
Hold the TX steady and adjust the RX. If You adjust TX, the other guy have to adjust also his RX and then his TX... a mess. It is much easier if everybody adjust only his own RX and keeps TX steady.
