There very much is a recommended standard operating practice. Not everyone follows it, but if they would, there would be less drifting about. If you can't tune both, tune the higher frequency.

There is not a set standard. When working the linears, you will find operators that adjust [1] uplink and downlink (usually computer controlled), [2] adjust only the uplink, and [3] adjust only the higher frequency. The latter two are normally operators performing manual tuning, but I have seen some using computer control for one VFO/radio Most common method for manual tuners and the one I use, is to fix the lower frequency (most often VHF) and adjust higher frequency (UHF) for doppler. If you are calling CQ, then pick the method best to your ability. If you are answering a CQ call, then either [1} switch to their method or [2] make your call very quick, before doppler drifts away. 73, Robert Bankston, KE4ALAMSAT-NA VP of User Services Twitter: @KE4ALabamaWebsite: KE4AL.wordpress.com

Just asking for clarification, or how do most do this...
When working a Sat other than FO-29 (where I stay locked on the 2 meter up frequency and tune the 70cm down frequency), say one of the XW or CAS birds where the downlink is 2 meters and up is 70cm... which frequency stays locked and which gets tuned? I've read that you tune the higher frequency, but then wouldn't the other station be chasing me?
