Officially part of the SAFE-T P25 upgrades.... Most likely either the ISP D 52 or IGC North sites testing for when the upgrade reaches us in central IN. We are phase 3 of 6. Guys down south, look for new P25 CC's.. If they are testing it here, then it will be popping on in phase 1 soon. I would hazard a guess that some of the other 148 sites should also be in testing. Now showing P25 Phase 1.. So seems like flavor might fluctuate til they get it all up. From the statements from the state, this is going to be an FDMA (P25 Phase 1) only system.
