I did experiment with this concept a couple of years ago. At the
remote site, I captured I/Q from a LP-Pan to a sound card, using ulaw,
and streamed that to the local PC, where I fed it (via VAC, I think)
into some "SDR" software (maybe NaP3). It worked, but it was a
bandwidth-hog. To get 192kHz with 16-bit samples, I think that adds up
to 6Mbps. I suspect that not many remote sites have that sort of
upstream b/w available....
