[amsat-bb] AO-73 Doppler shift

Hi all,

I'm having great fun on all the operational satellites, including AO-73.

However, I find that even using CAT control I have to adjust the uplink frequency almost constantly throughout the pass.

I have to shift buy about 3500Hz overall from start to finish, increasing all the time.

Is everyone else seeing the same effect?
