you're ASSuming they don't encrypt. Had an APX6000 template come into my hands from Coweta, and ADP is in use on most dispatch TG's. So let us know what (if anything) you can hear. I can't hear the WARRS system from my house in Smyrna.
Hopefully, the City of Newnan will follow the lead of the Coweta County Sheriff and remain "in the clear". They may have some tactical encryption use but the frequent visits I've made recently to Newnan, the Coweta Co SO has been in the clear and very active. This system has a good strong signal. I begin picking it up around Union City and can receive it all the way to LaGrange. Also, I begin receiving the Columbus-Troup System at the main Newnan exit on I-85 and can monitor them down I-85 to about Auburn.
I came through Newnan yesterday and they are still on their VHF channels. The West Georgia DTRS has great range on a scanner. I can monitor the Coweta side of the system on I-85 between Union City and LaGrange.
While in the southern part of Douglas County I can get Coweta off of a rubber ducky. To get Carrollton I have to point the yagi at the Fairplay tower. To get Villa Rica I have to be in their city limits or west of the city.
In my opinion, the Coweta part of the WARRS system is the best in the Atlanta Area.
