It's certainly nowhere near that now, but one can always hope :)

Since GMR-1 is so close to GSM, al the MM and CC layers of osmocom-bb
could probably be re-used easily.
The RR is completely different tough.

The current code doesn't have the 'modulation' part but that's
relatively easy. (all bursts types are described in a structure that
contains all the info already to make a proper gmr1_pi4cxpsk_modulate
function).
Then you'd need a real time interface to USRP which is a bit more
complex :) But it's something I'll definitely look into at some point
because I'd like to broadcast my own GMR-1 network :p


Cheers,
