Just an update on this. It's not trunked and they have had a lot of trouble with this new system. They've gone back and forth between digital and analog. They seem to have gotten it figured out and are using frequency 453.6125.
Has anyone seen evidence of these channels being interoperable/simulcasted on the 700mhz system down in that area? I wonder why they would spend the money to build out and go to their own P25 system that nobody else would be able to interoperate with. Unless possibly they have set this up temporarily as a way to transition into the world of digital
They could have patches to other local digital systems, and/or analog channels for interoperability. My local LE went to a VHF DMR system ~5 years ago, just this year they patched it to their TG on the statewide 800mhz P25 system, for surrounding counties to hear. They also patch the local school Corp UHF DMR system to one of their VHF DMR TGs during school dismissal, patch the County Highway analog 800Mhz channel, and statewide P25 TGs to their VHF DMR system randomly.
