What Is The Lowest Aviation Radio Frequency?

What radio frequency do pilots use?

One of its roles is to allocate all radio bandwidths and frequencies. 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.

What frequency do small planes?

Aircraft use Airband as their primary means of voice communication. In North America, the spectrum from 118.000 to 136.975 MHz is used with 25 kHz spacing and AM. As of 2010 aeronautical enroute and flight test stations may use 8.33 kHz spaced channels in the 121.4-123.6, 128.825-132.0 and 136.5-136.875 MHz ranges.

What frequencies do airports use?

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.

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.

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).

Is listening to air traffic control illegal?

You can listen to air traffic control radio transmissions It is illegal under the Wireless Telegraphy Act 1949 2006 to listen to anything other than general reception transmissions unless you are either a licensed user of the frequencies in question or have been specifically authorised to do so by a designated person.

What frequency do pilots use to talk to each other?

If you wish to talk to the pilot of another airplane, use the air-to-air frequency of 122.75 MHz. It is not considered good etiquette to fill other frequencies with pilot -to- pilot chats. VOR frequencies are between 108.0 and 117.975 MHz, immediately below aviation communication frequencies beginning at 118.0.

How do I listen to an airplane squawk?


  1. Tune in to the radar controller’s radio frequency BEFORE selecting a listening squawk (otherwise you won’t be listening )
  2. Select the listening squawk, using ALT (Mode C) if you have it.
  3. Listen out for any transmissions with your callsign or position [*]

How do I find flight frequencies?

The Flight Service frequencies are listed in a box above certain VOR stations. The most common frequencies are 122.2, 122.4, or 122.6. Also, most GPS (or iPad apps like ForeFlight) have a listing of the nearest Flight Service frequencies.

How do I find my Artcc frequencies?

4 Answers. In the United States, you can consult the VFR Sectional Chart and look for the frequency box located near a terminal area. Otherwise you’ll need to consult the Airport Facility Directory for the region your are flying to find a ARTCC (Center) frequency.

What is Asri frequency?

The ASRI Ground Station Administration service provides for the coordination, assignment, and licensing of VHF Aeronautical Enroute frequencies in the 128.825 to 132.000 MHz and 136.500 to 136.975 MHz spectrum to eligible aviation business customers IAW Part 87 of the FCC rules.

What frequencies do police use?

Public Safety Spectrum

Frequency MHz Available for Public Safety
25-50 MHz (VHF Low Band) 6.3 MHz
150-174 MHz (VHF High Band) 3.6 MHz [non-contiguous]
220-222 (220 MHz band) 0.1 MHz
450-470 (UHF Band) 3.7 MHz [non-contiguous]

Are air band radios legal?

It is illegal to listen to all aeronautical transmissions. However as mentioned above, the authorities have tended to turn a blind eye to listening to airband.

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.
