An airborne TACAN receiver can be used in air-to-air mode to provide the approximate distance between two coordinating aircraft by selecting channels with 63 channels of separation (e.g., aircraft #1 sets channel 29 into its TACAN and aircraft #2 sets channel 92 into its TACAN.). It does not provide relative bearing.
Portable transceiver, Ultra high frequency (UHF)-band, 3,500 channels, 225-400 mc, 7 lbs: Collins Radio: AN/PRC-68 [160] AN/PRC-74: Portable HF radio: Hughes Aircraft (now Raytheon) AN/PRC-77: Portable Very High Frequency (VHF) radio, forward area, 3-5 Mile Range, replaced by Single Channel Ground and Airborne Radio System family of radios
The SINCGARS operates on any of 2320 channels between 30 and 88 megahertz (MHz) with a channel separation of 25 kilohertz (kHz). It accepts either digital or analog inputs and superimposes the signal onto a radio frequency (RF) carrier wave. In FH mode, the input changes frequency about 100 times per second over portions of the tactical VHF-FM ...
Single Channel Ground Air Radio System with Enhanced SINCGARS Improvement Program (ESIP), 30-88 MHz, FM, frequency hopping and single frequency; HAVE QUICK II military aircraft radio, 225-400 MHz, AM, frequency hopping; UHF SATCOM, 225-400 MHz, MIL-STD-188-181, -182, -183 and -184 protocols
Multifunctional Information Distribution System (MIDS) is the NATO name for the communication component of Link-16.. MIDS is an advanced command, control, communications, computing and intelligence system incorporating high-capacity, jam-resistant, digital communication links for exchange of near real-time tactical information, including both data and voice, among air, ground, and sea elements.
Its frequency range is extended and includes the following bands: VHF 30-88 MHz close air support; VHF 108-118 MHz navigation; VHF 118-137 MHz air traffic control; VHF 137-156 MHz land mobile; VHF 156-174 MHz maritime; UHF 225-512 MHz military/homeland defense; UHF 806-824, 851-869, 869-902, 935-941 MHz public safety bands
Link 16 is a TDMA-based secure, jam-resistant, high-speed digital data link that operates in the radio frequency band 960–1,215 MHz, allocated in line with the International Telecommunication Union (ITU) Radio regulations to the aeronautical radionavigation service and to the radionavigation satellite service.
However, the military secretly developed a largely duplicate system called TACAN. The system was revealed in 1952, but work continued into 1955, when the redundancy of effort caused controversy.
