If I remember correctly, wasn't TxDPS using the NCTCOG system on the Tarrant County site for patrol on the CTP in Tarrant County/Johnson County?
I have not seen any talkgroups on Fort Worth Layer 1/Layer 2 for DPS on the CTP since the cutover to NTIRN. Are they just using the DPS Tollways talkgroup on the Dallas site in Tarrant County/Johnson County?
