Trying to figure out how Cheboygan County local authorities use the MPSCS trunked system. Im familiar with their conventional system but was wondering what agencies have moved over. Specifically Tuscarora Twp police, fire, and EMS. Anyone know? From scanning the RR database, I see regional TG's but nothing to confirm it covers the 49749 stations of Tusc. Police/Fire and the Indian River based 62 alpha EMS.
