OK, please bear with me here. For several years I loaded only the Sullivan county Motorola trunk system into my pro 2052(manually) ,163, and 197(software). Everything on the Motorola system is still there except for Bristol police fire etc..
Loading the Project 25 gives me non of the stations on the Motorola system including Bristol. Would just some of the frequencies in this group have been rebanded instead of going digital? I know I am missing something here.
Sullivan County and Bristol PD are still on their Motorola trunked system. They have not switched over yet to the TACN (P25 system) that I am aware of and if they had switched over, I'm sure someone here would have noticed that.
There is a possibility that the control channel changed and if that's the case you will just have to figure that out. I personally have not been up that way in a while, but the last time I was there (about a month ago) everything was still working fine.
So, you are picking up any other talk groups on the system, such as Sullivan Co. Sheriff, Fire or EMS or Kingsport? If you are picking them up, then it could be they changed talk groups or your programming may be messed up. If you can't hear any of the other TG then it could be a control channel change.
If it had been rebanded, then you wouldn't hear any of the other talk groups, just as if the control channel changed.
Just a couple of thoughts.
