What is Air Band? A Complete Guide to Aviation Radio Frequencies

Listen to the Skies: Air Band Explained
Air band is one of the most fascinating features on modern ham radios — but many operators do not even know they have it. Here is everything you need to know about listening to aviation communications.
What is Air Band?
Air band is the VHF radio spectrum used for civil aviation communication, spanning 108 to 136 MHz. Unlike most ham radio frequencies that use FM modulation, air band uses AM (Amplitude Modulation). This is why you need a radio that specifically supports AM reception in this range.
What You Can Hear
| Frequency | What You Hear |
|---|---|
| 108.0-117.95 MHz | Navigation aids (VOR, ILS) |
| 118.0-121.4 MHz | Air traffic control (tower, approach, departure) |
| 121.5 MHz | Emergency / guard frequency |
| 121.6-121.925 MHz | Ground control |
| 122.0-123.5 MHz | Flight service stations, UNICOM |
| 123.6-128.8 MHz | Air traffic control center |
| 128.825-132.0 MHz | Company frequencies (airlines) |
| 132.025-136.0 MHz | Additional ATC and data |
How to Listen
- Program local airport frequencies. Find them on AirNav.com or RadioReference.com.
- Switch to AM mode. On the QUANSHENG UV-K1(8), air band AM is automatic when tuned to 108-136 MHz.
- Get higher. Air band signals travel line-of-sight. Higher elevation = more range.
- Use a better antenna. The stock antenna works but a dedicated air band antenna improves reception.
Is It Legal?
Yes, listening is 100% legal. Transmitting on air band frequencies is strictly prohibited unless you are a licensed pilot or air traffic controller. Your radio will not transmit on these frequencies — it is receive-only in this band.
