RF spectrum is usually approved and regulated by government. telephone or Single Channel Radio Access (SCRA) which gives isolated As a result of this particular configuration, the microwave radios tended to be lower in frequency (a relative term of course in microwave engineering), typically below 12GHz and often 6 or 4GHz. The Triffid Radio Relay Equipment (UK/TRC 471) has been designed to meet the requirements for a new generation of radio relay equipment for the British Army. The VRC321 can be linked, using standard Coaxial cables, to SURF (Selector Unit Radio Frequency), to avoid interference with other HF Radios nearby; and TURF (Tuning Unit Radio Frequency), to tune the radio to the attached antenna. First delivery of Ptarmigan equipment was to 1 Armoured Division HQ and Signal Regiment in December 1984, and it entered service in February/March 1985. enter into service at the turn of the decade (possibly 2011).

A broadcast radio receiver is called a radio. This is why commercial radio stations sometimes seem to overlap or blend together, and why the Federal Communications Commission strictly regulates the use of all publicly-owned airwaves. Headquarters; and a wide area component will allow the TRIFFID is used to provide the relay links within the system. 4100 sq. A major phased enhancement programme to provide high-integrity packet switched data, including mobile X.25 packet access, international interfacing and the development of equipment for use in armoured vehicles commenced in 1984 and was completed in 1992. The VSC 501 was the workhorse of the UK tactical military SATCOM system for some years. TRIFFID of BAe Systems. WW2 UHF Multi-channel set- The precurser to BRUIN and Ptarmigan radio relay equipment The Wireless Set Number 10 provided 8 duplex speech channels using multiplexers and pulse code modulation (PCM) which was very advanced in 1944. The systems are supplied by EADS Astrium subsidiary company Paradigm Secure Communications.[5]. digitisation would be 'like giving birth to a 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. They covered the provision of the full range of Ptarmigan items from small individual equipments, such as subsets, to major vehicle-mounted installations such as switches and SCRA radio centrals. During the years of the Cold War Royal Signals units in 1st British Corps trained with BRUIN, and deployed their equipment and vehicles among the woods and farms of northern West Germany, putting their skills to the test in an annual cycle of command and signal exercises.[11]. In August 1993, a £22 million contract was awarded to modify the system to allow deployment over long distances with satellite links. The Bowman C4I system consists of a range of HF radio, VHF radio and UHF radio sets designed to provide secure integrated voice, data services to dismounted soldiers, individual vehicles and command HQs up to Division level.
