Yesterday, I made my first connection with the CAS-4A, CAS4B and AO-7 linear transponder satellites. No QSO yet, but one step at a time. As I began calling CQ in CW mode, I was not sure how to best compensate for Doppler. It it best practice to only adjust the transmitter? The receiver? Seems like either way has the potential to unintentionally cause QRM.
The CAS satellites are moving along so fast that it seems to require constant Doppler compensation. With a near overhead pass, it's only about 13 minutes from horizon-to-horizon. Anyway, I was happy just to have made it into the satellites after two months of gear prep.
