Attempt to extract callsign from 10 char YSF frames. When YSF headers are missed (late entries), extract callsign from one of the VD2 frames. If no DMR ID can be found after all of these attempts, use an optional default DMR ID, defined in main.h. Also append a main.h defined module char on RPTR1 when no char exists in REF mode. This is the case for OpenSpot 1 users that can not assign a module char to their RPTR1 when in REF mode. DPlus reflectors allow RPTR1 callsings with no module char, but stock xlxd does not.
