[amsat-bb] sdr receiver

I am thinking of upgrading the station by removing the ft817 as downlink receiver and going to SDR receiver.

Looking for best data to get started and choice of SDR unit to use.

Open to hearing pro and con!

Also interested in raspberry pi plus SDR to do the job. I have no experience with raspberry but appears to becoming popular.

Can SATpc 32 control a sdr as it would any transceiver?
