I have a question regarding software doppler correction - in particular when using linear satellites.

I am working on some control software that is a little more flexible than what I've used. I really like SatPC32 on Windows and Predict/gsat on Linux. I haven't yet fallen in love with any available software, but that's really a different story.

I can imagine that doppler correction for an FM sat is rather easy in that you simply tune the transmitter/receiver to the published frequencies depending on the operating mode.

I'm a little less sure how that would work for a linear satellite. As mentioned before, I do have a chart from AMSAT that lists channelized frequencies for them. If I can tune the transmitter such that the frequency at the satellite is one of the listed frequencies, how sure can I be that the receive is as published?

Can I extend that to the point where I would be able to automatically determine frequencies (at the satellite) of the downlink for a given uplink and then compute doppler from there? It would then be fairly convenient to tune within the satellite's passband and let the computer do the 'thinking'.

Thanks for any feedback.
