What's inside

  • What software-defined radio is in plain English
  • Why an SDR can hear P25 digital systems that analog scanners can't, for about $30
  • What you need: the dongle, antennas, and software, with honest setup expectations
  • First setup: drivers, SDR#, SDRTrunk, and the first waterfall
  • Listening to analog: police, fire, EMS, weather, airband, and marine
  • Listening to digital: P25 Phase 1 and 2, DMR, and NXDN with free software
  • Why antennas matter, and troubleshooting the common failures

Who this is for

Tech-curious listeners whose county has gone digital and who want a $30-$100 path to hearing it from a computer, without a $450 scanner.

Frequently asked questions

Is an SDR legal? Yes. Listening to unencrypted transmissions is legal. Decoding encrypted traffic is not, and this guide does not cover it.

Do I need a computer? Yes, an SDR works with a Windows, Mac, or Linux computer. It is a home-monitoring tool, not a pocket radio.

Is this hard to set up? The guide walks through it step by step. Expect a half hour of setup for your first listen.

How the zip code programming works

After you order, we program this radio by hand to the zip code you're shipping to — loading the local police, fire, EMS, weather, and public safety frequencies available in that area. It arrives channel-ready. No computer, no programming cable, and no CHIRP software.

Need it programmed for a different area? Leave the zip code in your order notes at checkout.

Will it work in my area?

Most US counties still run analog on at least some public safety channels, but a growing number have moved to encrypted or digital P25 systems that an analog scanner cannot receive.

Check your zip code before you order and see what's receivable where you live. We'd rather turn down a sale than ship you a radio that can't hear your county.

Shipping & returns

Free shipping anywhere in the United States. Each radio is programmed individually after your order comes in, then shipped.
