One thing I've discovered which makes things go more smoothly is to reduce the minimum Doppler tuning interval.
I am using SatPC32 V12.8a. There are two parameters in the CAT menu -- the Speed which I changed to 5x (which is not sticky) and the minimum Doppler tuning step for SSB which I set to zero (it will be sticky if you remember to click Store).
With these two changes, although the Doppler correction may drift off, it does so very smoothly, which I assume allows the decoding of the BPSK data to be more accurate.
