Are aircraft radios VHF or UHF?

The UHF air band operates in AM in a general range of 225.0–399.95 MHz. Many ATC functions have both VHF and UHF frequencies. For example, Newark Liberty Tower uses 118.3 and 257.6. ATC will often broadcast on both the VHF and UHF frequencies.

What is the ATC frequency?

All ATC communications are between 118.0 and 137.0 MHz. If you think you’re given a frequency above or below those numbers, there is a mistake.

Do airplanes use AM or FM?

Aviation voice radios use VHF AM. AM is used so that multiple stations on the same channel can be received. ( Use of FM would result in stronger stations blocking out reception of weaker stations due to FM’s capture effect).

What frequencies do airlines use?

In the United States, VHF civil aircraft communications are placed in the 100 MHz band and allocated 760 channels within the range from 118.0-136.975 MHz. As a pilot, every frequency you talk on will fall within this range.

Can UHF and VHF radios communicate?

It is not possible to match UHF and VHF frequencies, because UHF radios only communicate in UHF 430-470 MHZ range and VHF radios communicate in VHF 150-174 MHZ range.

What is better UHF or VHF radio?

In general, UHF radios are better for indoor use because their wavelengths are shorter and better able to penetrate through steel and concrete. VHF radio signals tend to degrade more than UHF signals indoors.

How far can UHF transmit?

Since UHF transmission is limited by the visual horizon to 30–40 miles (48–64 km) and usually to shorter distances by local terrain, it allows the same frequency channels to be reused by other users in neighboring geographic areas (frequency reuse).

How do I listen to ATC frequencies?

If you’ve got nothing better to do on one night, visit LiveATC.net, where anyone with a computer or smartphone and a passing interest in aviation can listen to control towers live, worldwide, and in full action. Student pilots use it to listen to their local airport to get accustomed to the myriad radio calls required.
