So, TRamrod38, not going to tell us who it is to whom you're referring?

Claims that a MOTOTRBO system isn't working correctly but won't tell who it is. Why not?

I believe clarksville sheriff has made the switch or something weird is going on. sheriff, ems, and vol fire were on the district 7 system, and now I can pick up everybody else except for sheriff, also we have a 911 call log, and they have changed names and units up with them. I haven't found any nexedge systems yet, but here is a license they submitted changing stuff around ULS Application - Public Safety Pool, Trunked - 0005883064 - MONTGOMERY, COUNTY OF

EDIT: also I found this on my city's (clarksville) website read to page 7 please and tell me what you see http://www.cityofclarksville.com/mod...ocumentid=1806

The D7 system is converting from LTR/LTR Passport, to NexEDGE digital sections at a time. Some agencies will be going over to the TACN once buildout in that region is completed ... Its a common theme with a lot of LTR systems nationwide. They are converting over to either DMR, or NXDN formats. (See NY, MS, among other states for examples. Also check out various system operators letters of intent to FCC, talk with other admins that work for companies like Motorola who are the only DMR Trunking Solution currently and so on ad infinitum. They may can't tell you specifics due to confidentiality clauses, but can tell you it is happening.) Important note: Due to massive FCC backlogs, an agency may switch long before you see an "official" changed status in the FCC db. I have recieved multiple confirmations, and confirmed a couple myself that still have NO DMR, or NXDN emissions designators for either on FCC licenses. (FCC Narrowbanding mods and new licenses are still popping up and most of that was supposedly completed back in the first quarter of the year.)

Hmm this is weird. My sheriff is gone here I can't find them, I can't find any new channels or anything unless they went 700 MHz which none of my scanners can pick up

Were they on the LTR originally? If so, monitor it's freqs conventionally and see if you hear digital. If so, then run your dsd etc on it and see what it says.

Montgomery County Sheriff has made the switch to NexEdge. All other MC agencies will follow suit over the next couple weeks. This is part of the D7 trunking system. They are running NXDN trunked and encrypted.

Trying to monitor an encrypted public safety system sounds like a good way to go to jail. YMMV

Just logging TG's is legal. Monitoring vias actual radio on system without permission is good way to get radio bricked, or fined/jailed. Monitoring if you have permission is ok. Monitoring encrypted is not happening unless the agency gives you the key every time they flip codes, so we all know that. Passing on data that you got by using a radio on the system with permission, means you work for either the TN DHS, or another agency on the system, thus putting your job at risk, but hey, as long as you know the risks, have fun.
