A while ago I remember a thread that asked about either NTTA or TxDOT frequencies, can't remember but I do know for sure about NTTA.
They're now using FirstNet's PTT service with the Sonim XP8 phones. They have been for a while however they used to have a courtesy patrol frequency on VHF, to my knowledge that's now no longer in use as the trucks don't have radios installed anymore. I don't see it anywhere in the RR database either where it used to be.
Just an FYI.
