It's about time they did something. The current system tends to flake out a lot though I'm surprised they didn't go for one of the VHF DPS channels.

Puzzling they went with UHF.
Unless this is for maintence or something like that.
All the DPS Tollway troopers use VHF. Why on earth assign them a UHF channel now.

I'ts been years since I lived close enough to hear it. Last I knew they had DPS on their own channel for a while then they cancelled the license for 155.4525 everything was back on the 157.35 repeater in Addison. Is that how it currently is?

I was looking at one of the new UHF locations and discovered that sometime recently they added new 157.35 repeaters in the same locations.

Maybe they are building two simulcast systems. VHF for DPS and UHF for maintenance.

Update 04/2017

New applications for repeaters on 151.13.
ULS Application - Public Safety Pool, Conventional - 0007737580 - NORTH TEXAS TOLLWAY AUTHORITY
ULS Application - Public Safety Pool, Conventional - 0007744646 - NORTH TEXAS TOLLWAY AUTHORITY
But 151.13 is or was the input to 157.35. I don't know if they are swapping the inputs/outputs or getting off of the marine band frequency for some reason. Interesting that the apps don't have any mobile or control stations.

There is what appears to be tollway roadside assist and wreckers on the PDV 900 DMR system ID 1499880, I have yet to identify exactly who it is. I have also heard some on the MHZ system that is already listed in database. Not sure on DPS, but on the pdv system, the dispatcher has some kind of direct contact w them.

Dredging this up...

The output is 151.130 (PL 136.5), unknown what the input is yet.

 

[nd5y]

I think they swapped frequencies. Input is probably 157.35 now.

Two possibilities:

1 - UHF does much better in all that glass, concrete and steel.
2 - VHF is packed and nothing was clean by coordination.

Also NTTA isn't Texas DPS. They don't think, plan or operate like DPS.

This is correct.

 

[KevinC]

You'd think someone would have updated the database by now if it's been known they changed frequencies.

 

[nd5y]

They licensed another VHF repeater in Mansfield this year.

As far as I know nobody has reported if the UHF system is active or what it is used for.

I live near the Chisolm Trail Parkway in SW Ft. Worth, the 151.13 repeater is very active. From what I hear, they have linked repeaters so all traffic is heard.
