From what I recall, the system is dual-mode (TDMA and FDMA). Most fire/EMS talk groups will operate in FDMA mode to allow non-TDMA radios (mutual aid) to interoperate. FDMA talk groups should be monitorable by P25 700mhz capable scanners. TDMA talk groups -- who knows.Yes it is and they did say that. I vaguely recall reading here that there are certain modes the system could operate in that would allow it to interface with other area systems. That could be it.
