My 2¢ worth...
As Larry posted on 8/12, Union Co GA finally activated their NXDN full-time for Sheriff, Fire, and EMS.
It's running in mixed-mode. I still hear quite a few county mobiles and portables in analog mode. The GSP troopers use analog on their P25 radios to communicate with the county's dispatch center on 155.730.
If you're without a NXDN radio, you can still hear the analog stuff, but be sure to activate your tone squelch (if your scanner has that feature) to keep the NXDN 'growl' at bay... If the PL/CTCSS tones aren't still in the RR database, here's a re-cap:
Sheriff's main (MDR) 155.730 uses 206.5,
FD Disp/Paging (VORTAC) 154.190 uses 91.5,
FIRE Tac 155.085 uses 71.9,
Black Mountain (south county LE/FD/EMS) 154.145 uses 107.2
I haven't heard any NXDN on the Sheriff's simplex tac 151.055 but since I've seldom heard it in use, I have no idea if it's ever had tone.
On my non-NXDN scanner (BCD996) today, I heard some very low-powered NXDN-type digital on the county's Road Dept channel 155.925 ... it might be mobiles/portables on simplex but my Uniden SDS in the same room (different antenna) ignored it completely. More mysteries to solve.
73 to all.
