Aircraft Frequencies
World Wide HF and VHF/UHF Aircraft Communications Listening

What do you need to get started listening to the world of monitoring HF Aircraft communications?

A good outside antenna will help your receiver to receive the signals much better.

Who, what and when!

Aircraft communications from over the oceans can be very boring at times or very exciting!
Along with the use of satellite communications, commercial and military aircraft use either the VHF/UHF frequencies when over or near land and switch to worldwide or nearly so, HF frequencies when over oceans and far beyond line of sight with land based ground stations.

They are not active all the time and are not always on the frequency that you are, so be patient and tune around the frequencies listed on this page.

The aeronautical voice communications stations and frequencies listed in the tables below are available to and utilized by the U.S. FAA Air Route Traffic Control Centers (ARTCCs) for air traffic control purposes.

The frequencies in use will depend upon the time of day or night and conditions which affect radio wave propagation especially on HF frequencies. Voice communications are handled on a single channel simplex basis (i.e., with the aircraft and the ground station using the same frequency for transmission and reception) unless otherwise noted in remarks.

The stations will remain on continuous watch for aircraft within their communication areas, and when practicable, will transfer this watch to another station when the aircraft reaches the limit of the communications area.

Stations listed below which are designated "FAA" are operated by the U.S. FAA Flight Service Stations. Stations designated "ARINC" are operated by Aeronautical Radio, Incorporated.
Sections or frequencies highlighted in Green in the table below are usually long range and are usually transmitted in USB mode.
Other frequencies (VHF/UHF) are AM.

Military Long Range Aeronautical Frequencies
U.S. ARMED FORCES GLOBAL HIGH FREQUENCY SYSTEM
IS NOW CALLED
The High Frequency Global Communications System (HF-GCS).

The High Frequency Global Communications System is a network of single sideband shortwave transmitters of the United States Air Force which is used to communicate with aircraft in flight, ground stations and some United States Navy surface assets. All worldwide receiving and transmitting sites in the HF-GCS system are remotely controlled from Andrews AFB.

PUBLISHED FREQUENCY LISTING - HFGCS stations operate on “core" frequencies to provide increased "Global" coverage. The published frequency listing does not reflect complete system frequency authorizations. These published frequencies will be used for initial contact, EAM broadcasts, and short-term C2 phone patch and message delivery. Other extended or special services will be moved to each station’s available "discrete" frequencies.

You may hear highly encrypted or coded voice transmissions at times that make no sense whatsoever. Just be patient. Military and national security at work!

HF-GCS stations tend to operate in the aviation bands clustered around 5, 8 and 11/12 MHz, although other frequencies are in use.

The primary HF-GCS voice frequencies are 4724.0 KHz, 6739.0 KHz, 8992.0 KHz, 11175.0 KHz, 13200.0 KHz and 15016.0 KHz.
Primary HFGCS Frequencies 24 Hours:   8992 and 11175
Back up HFGCS Frequencies Day:        13200 15016
Back up HFGCS Frequencies Night:      4724 6739

In addition to the HF-GCS, U.S. aircraft frequently use Military Affiliate Radio System (MARS) HF stations (13927.0 KHz) and Canadian Forces HF stations (11232.0 KHz) to relay messages.

Although transmissions are often single sideband, the use of the ALE , a type of digital transmission mode, is more and more common.

HF-GCS complements the use of satellite communications, and digital modes between aircraft and ground stations.
