The state of Tennessee Advanced Communications Network (TACN)

As stated before by me the TACN System Phase 1 Talkgroups are tracked perfect by the PRO197 PRO106 there is no reason to scan the TACN System as CONVENTIONAL.

witch way is faster to set up?

 

[buddrousa]

Its not about fastest its about tracking talkgroups and not missing traffic by just scanning voice channels.
The fastest way is to buy a Premium Subscription buy the software and program the scanner direct from RR Database.

 

[INDY72]

The speed comes from cc only and only program the sites you need. The more freqs the slower the scan.

Seeing that Middle TN build outs for added channel capacity and additional sites for City of LaVergne and MTEMC (Middle Tennessee Electric Membership Cooperative) is progressing.

Added 700 MHz channels to Antioch site under the LaVergne license (WREB540 (LAVERGNE, CITY OF) FCC Callsign Details) are now live as if Friday. Added 800 MHz channels to Smyrna site (WRDT998 (LAVERGNE, CITY OF) FCC Callsign Details) not yet seen active. If you have a vested interest in LaVergne, keep on eye on both Antioch and Smyrna sites. Have not seen new radio IDs or groups yet. Interesting to see as Antioch hosts TDMA traffic like most TACN sites, however never seen TDMA on Smyrna, maybe that will change soon. Will be curious to see LaVergne goes TDMA and/or encrypted.

Multiple new 800 MHz sites showing P25 test pattern traffic as of Friday. These are the added sites for MTEMC loading and coverage. A number of licenses for new sites from both TACN and MTEMC providing frequencies, plus some added frequencies to existing sites.

Expecting the following new TACN sites, once sites go live, will be able to confirm and submit site numbers and related details...

Keep on eye on Radio IDs 4111xxx and Group IDs 48150-48157, currently with limited FDMA activity for MTEMC.

Yay been waiting for this. And all you need is 3 to 5 freqs to roll on TRS especially TDMA

I picked up TG 10053 the other day when there was a large brush fire near the airport and national guard base in Alcoa. Two guys talking about coordinating with fire and police. My guess is EMA but not sure.

 

[INDY72]

Or Forestry of some kind.

Or an airbase / airport patch over. Far as I know neither civil or military side bought into TACN.

 

[Briar51rabbit]

That talkgroup is in the Blount County range.
My guess would be maybe Blount County EMA? But I didn't hear the traffic so I am just guessing.

 

[Remington12G]

Just had an encounter with TG 1501 on the North Bradley Tower, The DB has it labeled as I-PSAP 1 (Chattanooga Area), Under the Interop category. Around 5:45 PM a tone went out on the channel and a station keyed up and started calling the following Tennessee and Georgia Counties 911 Centers, In Tennessee: Megis, Rhea, Polk, Bradley, Hamilton. In Georgia: Whitfield, Dade, Catoosa, Walker. Does anyone know what this calling is and why.

 

[buddrousa]

My understanding is those are like regional inter city channels.

 

[INDY72]

PSAP's like any other TG can be patched. What your hearing is where they patched several of the PSAP TG's and ran the NET check in on a Super Group made of the combined patched TG's. You will hear this commonly now unless an individual PSAP TG is in use and busy on an event. NET checks are usually weekly, or monthly, or at the beginning of an event.

For over a month it has been my belief that the legacy Knox county Motorola type II system is no longer operational. It seems Knox simulcast frequencies are now fully active on TACN from the old system. In trying to confirm this today, I found a active Motorola analog trunking system today licensed in 2015 to Knox County as WPQD207 and a control channel of 857.2625 MHz. The system ID is 09F30h. It is similar to one of the old system IDs. It has 5 frequencies licensed on the license and the repeater site is licensed to be at Knox 911. Must be a backup trunking system, if they experience any issue on TACN.

 

[jblackst]

Zach, I believe you're correct on the death of the KNXCO Mot Type II system. My understanding was that once the new KFD Station alerting system went online, the plug would quickly be pulled on the old system. The only reason the old system was still online was to use the older station alerting.

 

[jpryor]

The five new MTEMC TACN sites are now active, networked and peered as of this morning:

Williamson, Franklin (Site 66) 855.1625-Control, 855.9375-Alternate, Also: 851.7750, 853.1750, 858.2875
Williamson, Thompson Station (Site 67) 854.9125-Control
Rutherford, Readyville (Site 68) 855.4125-Control
Wilson, Watertown (Site 69) 855.6875-Control
Cannon, Woodbury (Site 70) 854.8125-Control

Peers to and from both existing and new TACN sites across the MTEMC service area.

From initial observations with the new Franklin site, most radios are being denied, however there was some TWRA traffic active earlier.

Will submit once things stabilize a bit and the further active frequencies are confirmed across each new site.

 

[davewhall29]

Picking up TG 10009. It's a Blount County FD channel. Most traffic I've picked up has been when Alcoa and Maryville FD have been dispatched together on a mutual aid fire call.

Also heard 10034. Blount Co. Sheriff Dept on a special event...some type of bike ride or similar event. Heard them talking routes and setting up road blocks along the route to protect the riders.

And hearing 48015. In the Sevier County range. Not sure what it is, possibly trolleys or buses. Definitely not law enforcement or first responders. Heard them giving 2-digit unit numbers, saying where they were and where they were going. Ecample: "Unit 16 at station, returning."

 

[INDY72]

Someone please make a proper submission of the new sites, and can we have someone please nail the data for Washington County 700 MHz Sites? CC's, ACC's, Site NAC's etc...

Can you run Unitrunker, or Analyze, or the like on that system and get the data? CC, ACC, Connect Tone etc... And it was an third site for the original system as backup. So now it would be a fallback for TACN unless they shut it down too.

Hearing more traffic on this TG. Now I'm hearing 900 unit numbers and it sounds like trolleys. Still not enough to confirm this ad the trolley TG.

I can confirm that the Trolley buses have APX4500's with O2 heads up front.
