Modern police and fire departments use digital radio systems like P25 Phase I and Phase II. I use Uniden scanners to monitor these communications and stay informed about what's happening in my area.
Check out my Scanner Guide for detailed information on getting started.
SDR technology allows you to receive a wide range of radio frequencies using inexpensive USB dongles and computer software. It's an affordable way to explore the radio spectrum.

Radio scanning is about transparency and staying informed. Citizens have a right to know what their public safety agencies are doing. Unfortunately, many departments are moving to encrypted systems that lock out the public.
