OK, I see you're connecting PowerSDR to the VAC at 48kHz and DM780 / Fldigi at 8kHz.
So the VAC driver will have to convert the data, I'll bet it's this logic which is causing the spur (note - I am often very wrong). I don't have any Flex radios at the moment so can't try my idea but I would try selecting 8kHz on the PowerSDR when connecting to the VAC so that there's no sample rate conversion. Tim should think about this - it could be a bad idea (I'm not a PowerSDR expert at all). In any event I would want to try with VAC running at the same sample rate each end.
