Is there another site, other than here on RR, that one can get a list of all talkgroups on the TACN, especially those that have been recently added?
in the Old Days, there used to be a bunch of places. I haven't seen any private entity that seems interested in plumbing the depths of the system and putting on their site. And, I've never found a leak with any TACN data in it, like budget data, grants, or powerpoints.
Saw this also:

GA - Catoosa County (023) - Fire & EMS​

If they were overflying that tower, it would be reasonable to believe the aircraft was talking on those two talkgroups. Most users are geofenced, but it would also make sense that helicopters and interstate units wouldn't be.

is any of the other P25 systems that are standalone right now going to be folded into TACN for more coverage?

Rural/Metro Fire is now on TACN for primary communications. For now, VHF is still active as Dispatch, Paging, and Station Alerting. But most voice traffic for responses will now occur on TACN. Most of the portables on the apparatus are 700/800 MHz Kenwood Viking VP6000s. Every apparatus has a also has a Tri Band Portable and Mobile for 700/800, VHF, and UHF. The RMFD Chiefs have Motorola APX8000s. Knox County Rescue also now uses their own talkgroups on TACN for responses. However, you will no longer hear a lot of traffic or responses from Knox County Rescue due to changes effective February 1st. RMFD has access to a few of the KCSO channels as well. They also have access to: Town of Farragut, Karns FD, Seymour VFD, and Knox Rescue Channels. Another set of channels they of course have access to is the AMR 800 MHz channels. Their radios include both the Blount AMR and Knox AMR operations channels for TACN. You will also hear the AMR Critical Care Ambulances and RMFD Fire Medics on both RMFD TACN channels and AMR TACN channels. However, AMR remains on UHF for primary communications in Knox County until radios can be upgraded.While, Blount AMR still operates on VHF for primary communications. KFD, KPD, UTPD and Knox Schools did not share any of their channels with Knox Rescue, RMFD, or AMR. But those agencies do have access to most of KCR, AMR, and RMFD channels. They also have access to shared interoperability channels from Knoxville-Knox County EMA when Interoperability between those agencies are needed. On mutual aid calls with Seymour VFD, RMFD may use the SVFD TACN channels or grab a VHF capable radio.

Looks like Haywood County is moving to TACN. They didn't say that explicitly, but reading between the lines...

Also, it looks like old THP APX7500s. One of the UID labels tells me it came out of 8836's unit.

Vanderbilt University Medical Center to be the first hospital system to join TACN.
Tennessee Advanced Communications Network expands to include state hospital systems
Do you think this could be the 47188 talkgroup (outer edges of Middle TN)? I would expect more activity, but it's pretty sparse where I'm at. Is anyone else in Davidson county seeing heavy usage?

I wonder if they gave them "brand old" radios (old THP ones)? If so, that may explain the THP UIDs using it. Surely they would reprogram the UIDs unless they don't really have a strict correlation (unlike Sumner County's system where UIDs directly correlate to org, type of radio (mobile/HT etc), and unit number). Maybe not?

I've seen the 402xxxx numbers (especially portables) used with other agencies, like TEMA, etc. THP UIDs are now 414xxxx, and here in West Tn, they are tied to personal cars and portables. I know some agencies have a pool of portables, and a fleet of vehicles. Those officers probably don't get the same vehicle or portable on a day-to-day basis.

Just curious as to the changes to Knox Rescue Squad that are limiting their radio traffic. You are correct, I have not heard them on TACN and I have not monitored VHF lately. I just monitored an MVA on RM with entrapment and heard no KVRS traffic.

Knox Rescue stopped running MVAs effective February 1, turning over primary vehicle rescue duties to the various fire departments in Knox County (RMF, KVFD, SVFD).

They are still primary for special rescue services.

Thanks for the information. Was it lack of manpower, or other issues?
