I've got a USRP, and with a laptop will be able to at least run some
of the canned demos, such as receiving 2 FM broadcast stations at once.
I'm going to attempt a "beacon" application that repeats a voice message
on some 2m nbfm frequency - not sure how far that'll be heard with
no power amp.

My USRP will have 1.2 GHz, so I'll at least be able to communicate nbfm
with ID-1s, and grab some spectrum plots of ID-1 DV and DD modes.
