When a system is setup that way if it detects a phase 1 radio it will kick everyone to phase 1 for a talk group etc for interoperability. Eventually going back to phase 2. Common on some systems when upgrading is occurring to latest.OK, now are you talking meaning that this is possibly Multi-Simulcast usage & Communications being used with the NMSP & possibly others switching & communicating on both P25 FDMA & P25 TDMA? If so, than it sounds like more & more NM Residents like me may need one of the new Uniden SDS Series Digital Scanners to help out with this.
It is a given as technology progresses in these systems it isn't a matter of if but when a switch has occurred to higher level of latest system technology which has been said what is going to happen down the road.
