Law Enforcement and Emergency Communications
for Waller County, Texas





Summary

In Waller County, 2 Radio systems are currently being used (as of 09/2011) this includes some older Conventional (non-trunked) and also a Trunked system which is part of the TxWARN (Texas Wide Area Radio Network) system.
Law Enforcement, Some Fire Department, and nearly all EMS radio traffic is on the Trunked System. Some of the Fire departments are still using the old Conventional (non-trunked) radios. Most of the action in Waller County is on the Trunked System.

UPDATE As of 11/2011 the Hempstead Tower has been "Rebanded". This is a process that is ongoing around the nation, in which the trunking systems in the 800Mhz Spectrum are being reprogrammed to use some newly released frequencies in the 800Mhz Spectrum. These frequencies once belonged to Nextel. The consequences of this process are that scanners that worked with the trunking system before, no longer will. A newer scanner that supports the "800Mhz Rebanding" is required to be able to track the trunking. Trunktracker I and II scanners likely will not offer the custom programming necessary to work with these new frequencies. Some Trunktracker III scanners will work fine, some may need the firmware on the scanner "flashed" with your computer to upgrade to the latest firmware. All Trunktracker IV Scanners should work fine with the 800Mhz Rebanded Trunking Systems.

Conventional

Backup (SO 2) - 155.9325Mhz (not sure if this is still active)

800Mhz
Note: This system is trunking, BUT you CAN (Without a Trunking Scanner) listen in to the voice channels and hear the radio traffic, however, you will not be able to lockout Harris County radio traffic that makes it's way onto this tower from time to time (when the unit's get close to Waller County their car's radio's switch to Hempstead Tower for best signal). Go below to the TrunkTracker frequencies and just program in the "Voice Channels" into your scanner, without the control channel. The most popular frequency on the tower is by far (greater than 80% of all radio traffic) on 852.90000Mhz. By this I mean you can hear 80% of all radio traffic or more during low activity, on that one frequency.

TrunkTracker III (or newer)

Control Channel(s) - 859.46250Mhz (main control) 853.60000Mhz (alternate control)
