I don't get this interpretation. The DMR transmission is a single digital stream (TDMA). DMR, unlike D-STAR and Digital Fusion, does not provide a digitally encoded callsign identification, but we haven't seen any indication that the FCC is citing people for using it, so long as they verbally ID according to the rules. GPS within that digital stream would seem to simply be accompanying telemetry, so long as identification is happening in the voice portion, it would seem to me that the transmission is identified. What am I missing?
