How to Scan Police and Emergency Frequencies with Your Ham Radio
Teilen
Know Before You Tune In
With a wideband receiver like the QUANSHENG UV-K5 or UV-K1, you can scan far beyond ham bands — including public safety frequencies. But there are rules you need to know. Here is the complete guide.
Is It Legal?
In the United States, listening to most radio transmissions is legal. However, a few restrictions apply: you cannot listen to cell phone conversations (which are encrypted anyway), and some states restrict scanner use in vehicles. Always check your local laws.
What You Can Hear
| Service | Frequency Range |
|---|---|
| NOAA Weather | 162.400-162.550 MHz |
| Ham Radio | 144-148 / 420-450 MHz |
| Air Band | 108-136 MHz AM |
| FM Broadcast | 88-108 MHz |
| Marine VHF | 156-162 MHz |
Finding Your Local Frequencies
- Go to RadioReference.com — the largest frequency database
- Search for your city or county
- Filter by category: Fire, EMS, Police, Public Works
- Program into your radio (RX only — never transmit on these frequencies)
Scanning Tips
- Use your radio scan function to cycle through stored channels
- Set scan delay to 2 seconds — avoids cutting off replies
- Program similar services together (all fire in one bank, all NOAA in another)
- Use CHIRP to organize dozens of channels quickly
