Lubbock scanner frequencies and radio system explained

Lubbock's police, fire and EMS dispatch is not on a frequency you can dial in on an old analog scanner. This page explains, from our own receiver, what the system is, which channels this site records and what hardware hears it.

The system

Lubbock Police, Lubbock Fire Rescue, EMS, the Lubbock County Sheriff's Office and the airport police share one trunked radio system, the Lubbock City-County Mutual Radio System. RadioReference lists it as an 800 MHz Project 25 (P25) Phase II system, and our receiver follows its control channel in the 800 MHz band. On a trunked system there is no single "police frequency": a control channel assigns each conversation to whichever voice channel is free, and the talkgroup, not the frequency, is what you follow. Control channels also change over time, so we do not print one here. The authoritative, maintained list of frequencies and talkgroups is RadioReference's Lubbock County database; we link it rather than copy it.

What this site records

Only the dispatch talkgroups, by name, all received in the clear:

Every transmission on those talkgroups is recorded, transcribed and filed under an incident; you can hear them on the listen live page about a minute behind the radio, or on each incident page. We say nothing about talkgroups we do not record.

What you need to hear it yourself

A scanner that follows P25 Phase II trunking: the Uniden SDS100 and SDS200, the BCD436HP and BCD536HP, or the Whistler TRX-1 and TRX-2 class. Analog scanners and digital scanners without Phase II cannot follow it. A software-defined radio (an RTL-SDR dongle or better) with SDRTrunk or Trunk Recorder works too; that is how this site listens. For a no-hardware option, Broadcastify streams the dispatch channels as Lubbock City-County Public Safety (feed 45909).

Weather radio

NOAA Weather Radio for Lubbock is WXK79 on 162.400 MHz, a plain FM broadcast any weather radio or scanner can receive.

Is it legal to listen?

Listening to public, unencrypted public-safety radio is generally lawful in Texas, as in most of the United States; using what you hear to help commit a crime is a separate matter. This is general information, not legal advice.
