Medium Frequency (MF) radio uses on frequencies between 300 kHz to 3000 kHz and propagates (travels) along the ground, this is called ground wave propagation. Combat net radio systems are typically used for tactical communications at section and platoon level upwards. 225-400MHz "HaveQuick" frequency hopped system (7000ch wartime mode, ~20 channels otherwise) "In 1951 the NATO nations decided to reserve 225-400 MHz for military use, and move air-ground-air comms to this band from the 100-150 MHz area." Ptarmigan remains the core equipment for the British Army Tactical In some parts of the radio spectrum the right to use a frequency band or even a single radio channel is bought and sold for millions of dollars. The terminals could be assembled and connected to the satellite network within five minutes by one soldier, even in darkness, to provide long-range secure voice, data and messaging services, as well as a store and forward (e-mail-type) facility. systems. [citation needed]. relay, asynchronous transfer mode (ATM) and legacy Synchronous and During the 1991 Operation Granby, Ptarmigan was deployed extensively throughout the operational area with extended satellite trunk links, and was heavily used by British and Allied forces. mid 1980s, Ptarmigan is a user friendly, computer controlled will provide the UK Armed Forces with the network enabled Trunk Communications System, and has undergone a number of upgrades to short distances - even through thick cover or the walls of buildings - including contact with the enemy - greatly increasing the Units supplied to the British Army operate in the 37 - 46.975 MHz range, voice (FM) transmission Mode. In August 1993, a £22 million contract was awarded to modify the system to allow deployment over long distances with satellite links. deliver pulse code modulation (PCM) and compressed digital voice The normal manning level for an VSC 501 station was a crew of two and the system could be set up to provide communications within 15 minutes. The set operates in the 2–29.9999 MHz range with a possible 280,000 channels.
