Best Police Scanner for Houston (2026)
Houston Police Department main dispatch is still open on the TxWARN P25 system — something fewer major cities can say in 2026. HPD's division dispatch channels are accessible with the right digital scanner. Tactical, SWAT, and narcotics are encrypted, but day-to-day patrol communications remain audible. Here's exactly what you can hear across Houston and Harris County and which scanner to buy.
Houston Police: Mostly Open — For Now
HPD main dispatch operates in the clear on the TxWARN P25 trunked system. Tactical, SWAT, narcotics, and some investigative channels are encrypted. Houston Fire and most Harris County fire/EMS agencies remain open. Harris County Sheriff primary dispatch is largely accessible.
Houston has so far resisted full encryption — but that status can change. This guide covers what's accessible today and the scanner hardware that works on HPD's P25 system.

HPD Division Dispatch
Houston Police Department patrol dispatch across its geographic divisions — North, Northeast, Southeast, Southwest, Central, South Central, Northwest, and West — is open on the TxWARN P25 trunked system. Day-to-day patrol, traffic stops, and incident response are audible.
Houston Fire & County EMS
Houston Fire Department dispatch and most Harris County fire and EMS agencies remain open. Fire suppression, medical calls, and emergency response communications are accessible across the county.
Harris County Sheriff
HCSO primary patrol dispatch is largely accessible on the Harris County P25 system. Most day-to-day patrol communications are audible; specialized units may vary.
Aviation (Hobby / Bush IAH)
William P. Hobby Airport and George Bush Intercontinental Airport ATC transmit on public VHF airband frequencies. Both airports are receivable with any digital scanner or VHF receiver.
METRO Transit
Houston METRO bus and light rail communications are partially accessible. Bus dispatch and METRORail operations are audible on their radio system frequencies.
NOAA Weather
Houston area NOAA weather broadcasts on 162.550 MHz (WXK58 Houston) with hurricane and severe weather alerts for Harris County and surrounding areas.
Scanner Recommendations for Houston
Which Scanner to Buy
You Need a P25 Phase II Scanner
HPD and Harris County use P25 Phase II trunked radio. To receive patrol dispatch and fire/EMS communications, your scanner must support P25 Phase II trunking. Basic analog scanners will not decode these transmissions. Older digital scanners that only handle P25 Phase I will also fall short. The BCD436HP and SDS100 are the two most widely used options for the Houston market.
Uniden SDS100: Best for Houston's Sprawl
Houston is enormous — 665 square miles of city alone, with Harris County extending well beyond. The SDS100's built-in GPS automatically loads nearby talkgroups as you move across the metro, making it the right choice if you're monitoring across multiple jurisdictions or driving the area. Battery-powered and portable, it fits in a glove compartment or works at a desk equally well.

At a lower price than the SDS100, the BCD436HP handles P25 Phase II and covers HPD's trunked system with identical digital performance. For home monitoring of HPD division dispatch, Houston Fire, and HCSO, the BCD436HP delivers everything you need. The trade-off is no built-in GPS — you program it for a fixed area of the metro.

The RTL-SDR V4 dongle paired with SDRTrunk software can decode P25 Phase I and Phase II on a Windows or Linux computer. At around $35 for the dongle, this is the lowest-cost entry into Houston P25 monitoring. It requires a computer running continuously and some configuration work, but it fully decodes HPD trunked communications when properly set up.

Frequently Asked Questions
Is Houston police radio encrypted?
Partially. HPD main dispatch — organized by geographic division (North, Northeast, Southeast, Southwest, Central, South Central, Northwest, West) — is in the clear on the TxWARN P25 trunked system. Tactical, SWAT, narcotics, and some investigative channels are encrypted. Houston Fire and most county fire/EMS channels remain open. Harris County Sheriff primary dispatch is largely accessible.
Do I need a digital scanner for Houston?
Yes. Houston and Harris County use P25 Phase II trunked radio systems. Analog-only scanners and older digital scanners limited to P25 Phase I will not decode HPD transmissions. You need a scanner capable of P25 Phase II trunking, such as the BCD436HP or SDS100.
What frequencies can I still hear in Houston?
HPD division dispatch, Houston Fire dispatch, Harris County fire and EMS agencies, Hobby Airport and Bush Intercontinental ATC on VHF airband, METRO transit and bus communications, Harris County Precinct constables (many open), and NOAA weather on 162.550 MHz.
Which scanner works best for HPD?
The BCD436HP or SDS100 are both well-suited for Houston. Both handle P25 Phase II trunking required for HPD's system. The SDS100 adds built-in GPS for mobile use across the Houston metro. Either scanner can be programmed with HPD's talkgroups via RadioReference.com.
Can I hear Harris County Sheriff?
Yes, largely. Harris County Sheriff's Office primary dispatch operates on the Harris County P25 system and remains accessible on most channels. Some investigative and specialized units use encrypted talkgroups. The vast majority of day-to-day HCSO patrol dispatch is audible.
