MTEMC

[kg4ere]

So after working an incident with Middle Tennessee Electric last week I noticed they had APX 05 radio heads in their trucks. I had thought that they previously used iDen for communications. In searching around I found an FCC order from April 2019 authorizing them to utilize part of the TCAN nextwork. Does anyone know if they are now utilizing TACN? I know they have their own 800 system in Middle Tennessee. I have search the forums and come up empty.
Thanks!

They will be moving to TACN. I want to say their cutover will take place in the next month or so

Thanks for the info. I have not listened to them since eons ago when they were on VHF I think.

Interesting, the MTEMC service area corresponds with a number of 800 mhz frequencies recently licensed as well. I take it they will be TDMA, and ideally not encrypted.

Posted most of this on the main TACN thread, however also updating here for those with vested interest in MTEMC progress.

The FCC filing and authorization between TACN/MTEMC and 700 MHz / 800 MHz channel usage definitely an interesting read.

Middle Tennessee Electric Membership Corporation

Grants request for waiver to share use of the Tennessee Advanced Communications Network's (TACN) 800 MHz facilities, and finds that no waiver is necessary for use of TACN's 700 MHz facilities

www.fcc.gov

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

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.

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.

P25 or Phase II?

 

[volstatescanner]

MTEMC as been using their new TACN talk groups a lot last week, they have their sites up and running and are using TACN sites. They are running everything in Phase2 TDMA and only allow TACN traffic that is Phase2 on their sites.

48150 is Murfreesboro Control
48151 is Murfreesboro Alternate
48152 is Lebanon Control
48153 is Lebanon Alternate
48154 is Franklin Control
48155 is Franklin Alternate
48156 is Woodbury Control
48157 is Woodbury Alternate

I may have missed it, and I apologize if I did.
Can someone advise what the TG’s are for their main dispatch?

 

[jpryor]

Thanks for confirm on the talk group names, seeing them posted in the database now as well.

The new Franklin site at least is also carrying TACN Phase 1 FDMA traffic. I routinely have THP District 3 Nashville dispatch on that site.

Will see how much activity pops up next time bad weather comes through.

I am also still seeing the MTEMC 800 MHz iDen channels are still active, so curious to see if and when that system may sunset. There are definitely more 800 MHz frequencies they can reclaim and repurpose.
