I too am a beginner and wondered about how to calculate doppler and/or
determine a rough estimation based on pass information (elevation/az,
etc.).  I tend to start about 10 kHz up on any given pass which seems
to be a reasonable approximation for most of the birds so far (I
started this way because I followed the AO-27 FAQ).

My biggest challenge is finding the signal while adjusting for
doppler.  Once I get it though, I'm good for the rest of the pass!
