Hi,
I wonder if the ham radio data protocol D-Star DD has already been done
with gnuradio? This is some wireless ham radio Ethernet at 1.2 GHz, see
for example
http://www.qsl.net/kb9mwr/projects/voip/dstar/DD_packet_structure.pdf.
The Icom radios go out of production, but radios like bladeRF or USRP
line would fit this just fine.
Before we invent the wheel over and over, maybe some work already has
been done we could hop on?! I am mor the analog/RF guy anyway, so
building digital stuff from scratch with gnuradio is at least difficult
for me 
With best regards
Ralph, dk5ras.
