Airband or aircraft band is the name for a group of frequencies in the VHF radio spectrum allocated to radio communication in civil aviation, sometimes also referred to as VHF, or phonetically as "Victor". Different sections of the band are used for radionavigational aids and air traffic control. [1] [2] [3]
Single Channel Ground and Airborne Radio System (SINCGARS) is a very high frequency combat network radio (CNR) used by U.S. and allied military forces. In the CNR network, the SINCGARS’ primary role is voice transmission between surface and airborne command and control (C2) assets.
Before 1 October 2002 it was known as the Global High Frequency System (GHFS). HFGCS stations tend to operate in the aviation bands clustered around 5, 6, 8 and 11/12 MHz, although other frequencies are in use. The primary HFGCS voice frequencies are 4724.0 kHz, 8992.0 kHz, 11175.0 kHz, and 15016.0 kHz.
The aircraft emergency frequency (also known in the USA as Guard) is a frequency used on the aircraft band reserved for emergency communications for aircraft in distress.The frequencies are 121.5 MHz for civilian, also known as International Air Distress (IAD), International Aeronautical Emergency Frequency, [1] or VHF Guard, [1] and 243.0 MHz—the second harmonic of VHF guard—for military ...

Multifunction Advanced Data Link (MADL) is a fast switching narrow directional communications data link between stealth aircraft. [1] It began as a method to coordinate between F-35 (the Joint Strike Fighter), but HQ Air Combat Command wants to expand the capability to coordinate future USAF strike forces of all AF stealth aircraft, including the B-2, F-22, and unmanned systems.
They had three weapon pylons and served in the 5th Air Brigade (Spanish: V Brigada Aérea). During 1976, 25 A-4Cs were ordered to replace the North American F-86 Sabres still in service in the 4th Air Brigade (Spanish: IV Brigada Aérea). They were received as is and refurbished to flight status by Air Force technicians at Río Cuarto, Córdoba.
Once the target frequencies were identified, radio frequency jamming could easily be employed to degrade or completely disable communications. The Have Quick program was a response to this problem. Engineers recognized that newer aircraft radios already included all-channel frequency synthesizers along with keyboards and displays for data entry.
