All of the low band frequencies are being returned. There may be a few cars with low band radios but they are slowly being removed and all new cars do not have a low band radio.Are any of the VHF low and or high band frequencies still in use in the District 3/Nashville area any?
Yep. I talked to a trooper from District 7 not too long ago and he was showing me his unit. He had the low band turned off saying it wasn't used anymore. Im guessing they want to get away from the larger antennas and vhf hi is a good compromise for a backup.
I feel your pain. AL troopers just discovered repeaters a year or two ago. They revert to duplex non-repeat at random. The mountainous areas have to utilize different towers at times or switch to a county SO channel to communicate when they cant reach one of the 3 dispatch centers. The towers are linked by phone line, so mobile units were hard or impossible to monitor in the past unless you had an antenna with some height.Not really.
Tennessee has always been a PITA for the Troopers with regards to communications. Flatlands surrounded by corrugated mountains has necessitated multiple, complicated radio systems.
...Too bad, VHF-Low is a great piece of analog spectrum, but we march forward, right?
Can you advise what the other "back up" high band frequencies are--perhaps like 155.43?All of the low band frequencies are being returned. There may be a few cars with low band radios but they are slowly being removed and all new cars do not have a low band radio.
The high band frequencies are remaining as back ups to the TRS. The 159.090 repeaters are still active in the Nashville District as backups. The 154.905 low power mobile extenders are no more.
Should these frequencies would be programmed into the scanner as VHF Conventional, or as digital or trunked?
Yes, I know that before the THP switched over to the TACN, that these high band frequencies were analog/conventional. However, the TWRA, was using high band digital, before they switched over to the TACN. So, with the new radio equipment in the THP cars, I wanted to know if I should program these into my Whister 1080, as analog or digital. That was my question.Multiple Tones in use, differ for each TN DPS/DHS/THP/TEMA district, as well as an Statewide Access Tone, though are all liced now for P25 and there are plans to go to P25 for all State of TN Public Safety systems. It will take years before it could get fully done, but it eventually will happen. We have an listing I thought of the TNMA set up, including VTNMAs, UTNMA, and 8TNMA.

And for THP.. See the VHF High Band repeaters, each district has its own tones.

Always search the DB first, it is wise, it is your friend.... Then ask us and we will do what we can to assist,.. If that fails... Then the old dog has to come off the porch and search the bands.... If you find things in use we don't have listed, submit it to us and we will add it!
You can remove the low band frequencies from your scanner. All of the THP low band control stations and mobile relays have been removed from the state tower sites. There are still some mobiles left in the vehicles but most will be removed by early next year. The low band radios still in the vehicles are being disconnected by the Techs as time permits.I’m assuming all low band radios have by now been removed from vehicles. How about base consoles? I sure would like to purge THP low band from my mobile travel scanner.
Because my brain is backwards compatible, I’ll probably keep them loaded in a handheld until their FCC license expires February 10, 2024. Of course, that license, KA2856, includes mutual aid frequencies and no one will probably ever think to drop the low bands upon renewal.
