Thanks for the suggestions. Yes it is Clayton County. I tried 0x061 and 0x610.
I'm going to chalk it up to a bug in op25. I can decode the primary control channel fine. I can even get op25 to start with the example trunk.tsv. But whenever I use my edited trunk.tsv with my local info it crashes with te following. I think I'll take a drive today to a different P25 area and see what NAC is returned.
