Why restricted to 1000 megs??

Yes - of course!
But.....
I want a basic single band single feature (data!!!) radio yesterday!
We can get more bands and more features with product updates..
Changes add months to the release cycle

Sigi,
You asked what other group members think so I tell you what I think.
Your design suggestions may very well be good ones. I don't know, but the

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?

Use an rtl stick (dvbt usb stick)
Then your favourite sr software (be it hdsdr, sdrharp or whatever)
Route the audio to "soundmodem" and you can receive 1k2 or 9k6 packet
