VHF refers to VHF-Hi Band which are 160.nnnn frequencies. You are asking about UHF frequencies. It's an interesting question. UHF is very congested. They really want everyone on 700. From a technical standpoint, it is possible. From a political and potentially FCC one, I doubt they would.

I honestly never really understood why they even had VHF in TACN to begin with.

There are spots where studies showed vhf had better coverage. Thus the few vhf sites. Its like why MOSWIN is mostly VHF with a few 7/800 sites

 

[surfacemount]

Without rehashing the whole 700 is a political solution to the VHF/UHF scarcity issue, I feel like there had to have been another driver in those areas. (There are a lot of places VHF or UHF would do better, the equipment was way more available, etc etc etc)

 

[INDY72]

And then there are TACN oddities where the 700 sites hit far harder than vhf on same radios side by side where the vhf coverage is supposed to kill it. Strange but true.

The THP built sites were all going to be VHF initially but the FCC would not license any VHF trunking close to Virginia or Missouri to keep minimum spacing for co-license interference rules.

Here in Monroe County especially in the eastern part of the county we are having some difficulties with 700 in the mountains

I'm visiting the Tri-Cities (Johnson City, Kingsport, Bristol) area soon. What TACN sites should I monitor to pick-up local radio traffic?

The Sullivan County (050) site should cover most of Kingsport and Bristol. Buffalo Mountain (051) will cover the vast, vast majority of Johnson City. I have the other Sullivan and Washington County sites configured in my scanner, but never have had a need (that I'm aware of) to monitor the others. Both counties seem to adore broadly-deployed encryption, but you should still be able to monitor Washington County/Johnson City fire, EMS, and of course Tennessee Highway Patrol. Enjoy your time in the area!

Thanks for the info!

You will hear TN state LEA's, and some of the local FD/EMS... Only some though, as there is VERY HEAVY use of full time encryption there. And yes this includes events at BMS.

Hornbeak Site is down they working to get it back up

is it a busy singal

If your using the TRX-1 or 2, and have it set to tone for encryption then yes it does the bonk bonk bonk busy signal tones.

twra tgid 1203 is full time encryption

Unkown talkgroups

I have a few talkgroups that I have found I thought I would share to see if any
body might know what they are.

2105 , 2107 mention of C1 to C2 , 2109 , 2117 , 2093 encrypted , 1129 mention of school buses , and 13012

Hearing TGID 1129 on the Oswald dome site in Polk County. I going to make an assumption that this TGID belongs to Hamilton County since there are over twenty other TGID's in the 1100 range in that group. Can anyone verify this assumption?

Earlier this morning I heard TWRA put out an APB for a person who assaulted a police officer (Region 1? Dispatch 1, unencrypted). I'm guessing it went out over all of TACN and had to be in the clear due to intra-agency. They gave the description, driver, and the tag.

I hope we can continue to hear critical APBs in the clear as an extra set of eyeballs on the highway never hurts. I'd say kudos to TWRA for putting it out over dispatch 1, but I know they didn't do it for the public
