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, Sylvain
