Statewide Simplex Talkaround Channels
There are at least four VHF high band simplex channels, 151.0250, 151.0550, 151.0850 and 156.1350, which are commonly used for short distance hand held and truck communications at construction areas, by flaggers directing traffic, snow removal and sanding, etc. These channels are licensed for use anywhere in the state. They can be analog NFM or P25 digtal with PL 100.0 and NAC 293 monitored. Channel designators monitored are TXDOT-1, TXDOT-2, TXDOT-3 and TXDOT-4 in analog NFM mode and TXDOT-5, TXDOT-6, TXDOT-7, TXDOT-8 in P25 digital mode.
The channels used in a particular area or district may vary because there may be TxDOT repeaters or other licensed users on these frequencies in various locations throughout the state.
Simplex talkaround on local TxDOT repeater outputs has also been noted in some areas.

Old Channel Plans
- A few areas used high band frequencies, other low band frequencies and repeaters with outputs on 47 MHz channels and inputs on 45 MHz channels.
- These were the original low band statewide channels that were used until the 1990s.
| Frequency | Input | Type | Tone | Description | Mode |
|---|---|---|---|---|---|
| 47.1800 | BM | CSQ | Ch 1 Operations | FM | |
| 47.0600 | BM | CSQ | Ch 2 Statewide Base to Base | FM | |
| 47.0200 | BM | CSQ | (unknown use) | FM | |
| 47.0800 | BM | CSQ | (unknown use) | FM |
- Around the late 1990s several additional channels were licensed and most local operations were moved off of 47.18 to different channels in different locations. These were in use for around 10 years until TxDOT moved to the current VHF high band system in the 2000s.
