How to Listen to Fire Department Radio and Get Emergency Alerts on Your Phone

This page covers scanner apps: how they get the audio, which ones are worth installing, how to find your county fire channel and why some departments never show up.

How scanner apps work

A scanner app is not a radio. Your phone cannot pick up fire department frequencies by itself. Instead, volunteers, and in many cases fire and police departments and 911 centers themselves, connect real scanners to the internet and stream the audio to Broadcastify, the largest directory of public safety feeds. Apps like Squawster and Scanner Radio play those streams. That means two things: you can listen to any county in the directory from anywhere, and you can only hear what someone has chosen to stream.

Listening on Broadcastify is free. A Premium subscription, shared with its sister site RadioReference, removes ads and unlocks archives of past audio, so you can go back and hear what you missed. Check the current price on the Broadcastify site before you subscribe.

Scanner apps worth installing

Ratings, reviews and download counts were read on the US Google Play store on October 15, 2026. They change every day.

Squawster is new, so it has few reviews yet. Scanner Radio has the longest track record. All three play feeds from the same kind of public sources, so if a department is missing in one app, it is usually missing in the others too.

How to find your county fire channel

• Use the Near Me list first. Squawster and Scanner Radio both show feeds close to your location. Allow location access, or search for your city, county or ZIP code.
• Look for Fire in the feed name. Many counties have a combined Police and Fire feed. Others split Fire Dispatch, EMS or a big city fire department into their own feeds.
• Check whether it is online. Feeds go offline when the volunteer scanner loses power or internet. If yours is down, try a neighboring county, which often hears mutual aid calls.
• Turn on alerts. Scanner Radio can notify you when a nearby feed suddenly gets many listeners, a good sign that something big is happening.
• Try PulsePoint too. In many PulsePoint communities, you can tap a speaker icon to hear the live dispatch radio of that agency.

Why some departments do not appear

If you cannot find your fire department, there are usually three reasons:

• Encryption. Many agencies have moved to digital radio systems, often on the P25 standard, and some turn on encryption. Encrypted channels sound like noise to any scanner, and no legal app can decode them. Fire and EMS dispatch is encrypted less often than police tactical channels, but it varies by agency.
• No one streams it. Broadcastify feeds depend on someone running a scanner and sharing it. Rural counties often have no feed at all.
• Delays and gaps. Feeds can lag behind the live radio, and many cover only the main dispatch channel, not every channel crews use on the scene.

So treat scanner audio as a bonus, not as your warning system. For that, use the official alerts on page 3.

Is it legal to listen?

In most of the United States, listening to unencrypted public safety radio, on a scanner or through an app, is allowed. Some states limit scanners in vehicles or ban using them while committing a crime, and the rules in Canada are different, so check your state or provincial law if you plan to listen while driving or share what you hear. Trying to break encryption is never allowed.

Scanner etiquette that matters

• Do not go to the scene. Curious drivers block fire engines and ambulances. Stay away unless you live there and are told to leave.
• Never interfere with emergency radio. Transmitting on public safety channels is illegal.
• Think before you post. Scanner traffic can include addresses and medical details of real people, and early reports are often wrong.
• Do not use it to decide whether to evacuate. Follow official orders and alerts.
