So I can easily add more carriers to tetra-rx (I have 2 such GPUs), but tetra-rx doesn't seem well prepared for handling such situations, for instance the GSMTAP packets are not tagged by ARFCN -
Feel free to extend it in a way that keeps existing functionality but adds those bits as required. A lot of the state (like tetra_mac_state) is already not in global variables, so it should not be too hard. In terms of the ARFCN: I'd suggest just add the current arfcn to the PHY state and pass it up from there.
besides I don't have a good understanding of what others would want to do when demodulating multiple carriers. Personally I have to limit myself to traffic analysis on a fully encrypted network.
I don't think anyone has any big plans for osmo-tetra at this point. It mostly works for what we originally wrote it. Feel free to post any patches here for review / merge.
