Short Description Single side band, either lower side band or upper side band, is an AMAmplitude Modulation modulated voice channel with one sideband suppressed. Used in the HFHigh Frequency (3-30 MHz) band by amateur radio hams and aircraft weather reports.

Audio Sample
Single Side Band Voice, either lower side band or upper side band, is an AMAmplitude Modulation modulated voice channel with one sideband suppressed. Used in the HFHigh Frequency (3-30 MHz) band by amateur radio hams and aircraft weather reports. Single side band saves bandwidth.

Notable Users[edit]

High Frequency Global Communications System[edit]

This is a United States Air Force system. HFHigh Frequency (3-30 MHz)-GCS stations tend to operate in the aviation bands clustered around 5, 8 and 11/12 MHzMegaHertz (MHz) 10^6 Hz, although other frequencies are in use. The primary HFHigh Frequency (3-30 MHz)-GCS voice frequencies are 4724.0 kHzKiloHertz (kHz) 10^3 Hz, 6739.0 kHzKiloHertz (kHz) 10^3 Hz, 8992.0 kHzKiloHertz (kHz) 10^3 Hz, 11175.0 kHzKiloHertz (kHz) 10^3 Hz, 13200.0 kHzKiloHertz (kHz) 10^3 Hz and 15016.0 kHzKiloHertz (kHz) 10^3 Hz. In addition to the HFHigh Frequency (3-30 MHz)-GCS, U.S. aircraft frequently use Military Affiliate Radio System (MARS) HFHigh Frequency (3-30 MHz) stations (13927.0 kHzKiloHertz (kHz) 10^3 Hz) and Canadian Forces HFHigh Frequency (3-30 MHz) stations (11232.0 kHzKiloHertz (kHz) 10^3 Hz) to relay messages.

The system uses Upper Sideband Voice and 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 HFHigh Frequency (3-30 MHz)-GCS system are remotely controlled from Andrews Air Force Base. [1]

Emergency Action Message (EAM):[edit]

This is a system used by the US Military to direct nuclear capable forces to execute an operation. This sound file was recorded at 11.175 MHzMegaHertz (MHz) 10^6 Hz (Female Voice, Mainsail to Skyking) on 05-20-14 at 0035 UTC.
