Ham Radio Scanner Basics: How to Find and Listen to Hidden Frequencies

There is a Whole World of Radio Beyond Ham Bands

Your QUANSHENG radio receives far more than just ham frequencies. With a wideband receiver, you can scan police, fire, EMS, marine, aviation, and more — all legally. Here is how to become a scanning pro.

What You Can Legally Scan

Service Frequency Range What You Hear
NOAA Weather 162.400-162.550 24/7 weather broadcasts
Air Band 108-136 MHz AM Pilots, ATC, ATIS
Marine VHF 156-162 MHz Ship-to-ship, coast guard
FM Broadcast 88-108 MHz Music, news
Railroad 160-161 MHz Train dispatchers, crews

How to Find Local Frequencies

  1. Go to RadioReference.com — the largest frequency database
  2. Search your city or county
  3. Filter by category (Fire, EMS, Aviation, etc.)
  4. Program frequencies into your radio via CHIRP

Scanning Tips

  • Program similar services together (all fire in one bank)
  • Set scan delay to 2 seconds — avoids cutting off replies
  • Lock out NOAA channels during scanning — they transmit constantly
  • Use the squelch to skip empty frequencies
