Aviation radio frequencies are found in the low, medium, high, and very high frequency bands
Aviation radio frequencies are allocated across the low, medium, high, and very high-frequency bands. These frequencies are used for voice communications or for navigation.
Historically, aviation radio transmissions took place on the low-frequency band from 200 KHz to 415 KHz. However, as more reliable higher frequency systems were developed, most low-frequency air nav beacons were shut down. Today, some low-frequency beacons are still used for instrument landings and as backups in case of primary navigation system failures. Low-frequency transmissions are useful when other forms of communication fail because their long wavelengths are less affected by terrain and can bounce off the ionosphere to travel long distances.
Aviation radio is allocated a small portion of the medium-frequency spectrum, from 2850 to 3000 KHz. Most planes have radio direction finders that get a bearing by focusing on a medium-frequency transmission.
In the past, high-frequency bands were used for domestic voice communications. Today, high-frequency bands are used for voice communications for international flights, as they can travel longer distances than very high frequencies.
The very high-frequency band (VHF) is currently the most widely used for domestic aircraft communications. The VHF airband uses frequencies between 108 and 137 MHz. The lowest 10 MHz of the band, from 108 to 117.95 MHz, is reserved for navigational aids and precision approach systems. The upper band, from 118 to 136.975 MHz, is used for amplitude modulation voice transmissions.
To listen to local air traffic control, you will need a radio scanner capable of receiving frequencies within the very high-frequency band, specifically between 118.0 and 136.975 MHz. You can then use online resources to find aeronautical sectional charts of your local area and locate the closest airport to listen to weather forecasts, airport information, and pilot communications.

Radio scanners can be used to listen to local air traffic control
To listen to your local air traffic control, you will need to obtain a radio scanner that can receive frequencies in this range. You can then visit sites like SkyVector.com to find an aeronautical sectional chart of your local area. These charts show airports in your vicinity, denoted by blue or magenta circles, with lines inside representing runways. The control tower frequency is denoted by CT - 000.0, where the following numbers indicate the frequency used by ATC.
Once you have identified the correct frequency, you can tune your scanner to it and listen to air traffic control communications. Keep in mind that you may only be able to hear one side of the conversation, as some scanners are transceivers that allow two-way communication. It is important to never transmit on aviation frequencies, as the penalties for doing so are severe.
There are several common ATC and aviation-related frequencies that are universal across airports. For example, 121.5 MHz is the emergency frequency used by pilots in the event of an emergency, and 122.750 MHz is the frequency for general aviation air-to-air communications. You can also search for specific frequencies, such as Unicom communications used at uncontrolled airports, by scanning the frequency range of 122.0-123.65 MHz.
By using a radio scanner and referring to aeronautical sectional charts, you can listen to local air traffic control and gain insight into airport operations, pilot communications, and emergency situations.

Aeronautical sectional charts can help find the airport closest to you
If you're interested in listening to your local air traffic control, you can use aeronautical sectional charts to find the airport closest to you. These charts are available on websites like SkyVector and Flight Radar 24, and they provide valuable information about airports in your vicinity.
Aeronautical sectional charts are graphical representations of aeronautical information, including visual and radio aids to navigation, airports, controlled airspace, restricted areas, obstructions, and related data. They are designed for visual navigation of slow to medium-speed aircraft and are updated regularly to ensure accuracy. On these charts, airports are typically represented by blue or magenta circles, with lines inside indicating runways. Alongside each airport depiction, you'll find essential details, such as the airport name, its control tower frequency, and other pertinent information.
To start using aeronautical sectional charts, follow these steps:
- Obtain a radio scanner capable of receiving frequencies between 118.0 and 136.975 MHz. Brands like Uniden, Whistler, Icom, Yaesu, Grundig, and Kenwood offer suitable options.
- Visit websites like SkyVector.com to access aeronautical sectional charts for your local area.
- Locate the closest airport on the chart. Remember that controlled airports are usually denoted by blue circles, while uncontrolled airports are magenta.
- Note the control tower frequency (CT) next to the airport details. This frequency is given as CT - 000.0, where the numbers after the dash indicate the specific frequency used by air traffic control (ATC).
- Tune your radio scanner to the identified frequency to listen to air traffic control communications for that particular airport.
By using aeronautical sectional charts in conjunction with a capable radio scanner, you can easily find and tune into the airport frequencies closest to you. Remember to respect aviation communication protocols and never transmit on aviation frequencies, as severe penalties may apply.

LiveATC is a website that provides live feeds of air traffic control
To access LiveATC, users must first check if their country, city, and/or airport of interest are covered by the service. The website provides a list of countries where LiveATC is unavailable, including the U.K., Belgium, France, Germany, Iceland, Italy, New Zealand, and Spain, where streaming ATC communications may be prohibited by law.
The LiveATC website allows users to browse by U.S. state, Canadian province, or country to find an airport of interest. Once a desired channel is found, users can add it to their Favorites list for quick access. The website also offers a \"Nearby\" function to locate airports close to the user's location.
In addition to the website, LiveATC offers a mobile app called LiveATC Air Radio, available on the App Store. However, some users have reported a significant delay in audio streaming on the app compared to the website. The app also lacks the display of frequencies alongside the channel names, requiring additional steps to view the frequency of a selected channel.
LiveATC provides an opportunity for aviation enthusiasts to listen in on live conversations between pilots and air traffic controllers, catering to those interested in plane spotting or curious about the world of aviation communications.

Aviation frequencies are used for voice communications and navigation
Aviation radio frequencies are found in the low frequency (LF), medium frequency (MF), high frequency (HF), and very high frequency (VHF) bands. These frequencies are used for voice communications and navigation.
Historically, most air navigation transmissions took place in the low-frequency band from 200 KHz to 415 KHz. As more reliable higher-frequency systems were developed, most low-frequency air nav beacons were shut down. However, some low-frequency beacons are still used for instrument landings or as backups in case of primary navigation system failures. Low frequency is useful when other forms of communication fail because its long wavelengths are less affected by terrain and can bounce off the ionosphere to travel long distances.
Today, frequencies in the very high-frequency band are most widely used for domestic aircraft communications. Both communication and VOR navigational systems are operated on VHF frequencies. The Federal Aviation Administration (FAA) recommends that all aircraft with older 360-channel systems should be retrofitted with a 760-channel piece of equipment capable of operating in the 118.000 to 136.975 MHz band to support full VHF communications.
To listen to your local air traffic control, you will need a radio scanner capable of receiving frequencies within this range. You can then use sites like SkyVector.com to find an aeronautical sectional chart of your local area. This will allow you to find the airport closest to you so you can listen to weather forecasts, airport information, and pilot communications.
It is important to note that it is illegal in most countries to transmit on aviation frequencies without a license. Additionally, aviation communication requires specific phraseology to enhance safety and clarity. For example, pilots should use the phonetic alphabet when identifying their aircraft during initial contact with air traffic control.
