Houston Police Scanner: Main Dispatch Still Accessible
Houston Police Department keeps main dispatch and patrol channels open on P25 digital. Some tactical channels are encrypted, but most routine police activity is still accessible to the public. That access is worth protecting.
Houston Area at a Glance
Houston maintains more scanner access than most major U.S. cities. HPD has encrypted tactical and specialized units, but dispatch, patrol responses, and routine operations remain on open P25 channels that any digital scanner can receive.
Encrypting only the channels that genuinely require it, while keeping routine communications open, is an approach other cities have abandoned under administrative pressure. The question for Houston is whether that will hold.

Help Preserve Scanner Access in Houston
Pressure to fully encrypt Houston police radio is real, and budget cycles are when it tends to surface. Here is how to push back:
Watch the city council calendar
Encryption upgrades often appear as line items in police budget discussions without public debate. Monitor HPD budget hearings and city council agendas for radio system spending.
Support local journalism
Houston-area journalists depend on scanner access for breaking news. When newsrooms lose that access, accountability coverage suffers. Subscriptions and direct support matter.
Come prepared with specifics
If full encryption is proposed, have documented examples of how open radio benefits the public. Cities that encrypted could not show scanner access ever harmed officers. Houston's record is the same.
