Would it be possible/practical to set up GNUradio and a cheap SAT-TV SDR dongle as a quick, portable test set for the UDR's transmitter?

It would be receive-only, of course, but having half the test gear with you is better than none. :-)

I could certainly be done in 'spectrum analyser' mode, but it would be interesting to be able to at least receive and decode the beacons or packets that are being sent.
