Mike,
Roy is correct. The uplink frequency used by your transmitter *should* be lower at AOS and increase during the pass to LOS.

The below sounds correct to me. The speed of the object traveling toward you makes up for the lower frequency from terrestrial origin.

But the uplink frequency has the opposite behavior and is clearly not correct. That is - as the sat is headed towards you from AOS, the rig is tuned to a TX frequency LOWER than the TX frequency of the sat and it's increasing until TCA (where, momentarily the rig is tuned exactly to the sat's RX/upling frequency)... then begins to increase in frequency as the sat moves away towards LOS. None of that makes sense to me.
