The R1155 and T1154 sets were manufactured by several British radio manufacturers, including EKCO, Marconi, Plessey, and EMI. Ekco, who manufactured the R1155 and T1154 at its Aylesbury shadow factory, carried out extensive development work on both units before putting them into production, significantly improving on the original Marconi design.
Large numbers of war surplus R1155 radios were modified for private use postwar.

The early history of radio is the history of technology that produces and uses radio instruments that use radio waves. Within the timeline of radio, many people contributed theory and inventions in what became radio. Radio development began as "wireless telegraphy". Later radio history increasingly involves matters of broadcasting.
Aerospace is a term used to collectively refer to the atmosphere and outer space. Aerospace activity is very diverse, with a multitude of commercial, industrial and military applications. Aerospace engineering consists of aeronautics and astronautics. Aerospace organizations research, design, manufacture, operate, or maintain both aircraft and spacecraft.
The British Broadcasting Company Ltd. (BBC) was a short-lived British commercial broadcasting company formed on 18 October 1922 by British and American electrical companies doing business in the United Kingdom. Licensed by the British General Post Office, their original office was located on the second floor of Magnet House, the GEC buildings in London and consisted of a room and a small antechamber. On 14 December 1922, John Reith was hired to become the Managing Director of the company at that address. The company later moved its offices to the premises of the Marconi Company. The BBC as a commercial broadcasting company did not sell air time but it did carry a number of sponsored programmes paid for by British newspapers. On 31 December 1926, the company was dissolved, and its assets were transferred to the non-commercial and crown-chartered British Broadcasting Corporation (BBC).
The Harrier, informally referred to as the Harrier jump jet, is a family of jet-powered attack aircraft capable of vertical/short takeoff and landing operations (V/STOL). Named after a bird of prey, it was originally developed by British manufacturer Hawker Siddeley in the 1960s. The Harrier emerged as the only truly successful V/STOL design of the many attempted during that era. It was conceived to operate from improvised bases, such as car parks or forest clearings, without requiring large and vulnerable air bases. Later, the design was adapted for use from aircraft carriers.
The Plessey Company plc was a British electronics, defence and telecommunications company. It originated in 1917, growing and diversifying into electronics. It expanded after World War II by acquisition of companies and formed overseas companies.
Vickers-Armstrongs Limited was a British engineering conglomerate formed by the merger of the assets of Vickers Limited and Sir W G Armstrong Whitworth & Company in 1927. The majority of the company was nationalised in the 1960s and 1970s, with the remainder being divested as Vickers plc in 1977.
Ferranti or Ferranti International plc was a UK electrical engineering and equipment firm that operated for over a century from 1885 until it went bankrupt in 1993. The company was once a constituent of the FTSE 100 Index.
The Marconi Company was a British telecommunications and engineering company that did business under that name from 1963 to 1987. Its roots were in the Wireless Telegraph & Signal Company founded by Italian inventor Guglielmo Marconi in 1897, which underwent several changes in name after mergers and acquisitions. The company was a pioneer of wireless long distance communication and mass media broadcasting, eventually becoming one of the UK's most successful manufacturing companies. In 1999, its defence equipment manufacturing division, Marconi Electronic Systems, merged with British Aerospace (BAe) to form BAE Systems. In 2006, financial difficulties led to the collapse of the remaining company, with the bulk of the business acquired by the Swedish telecommunications company, Ericsson.
Pye Ltd was an electronics company founded in 1896 in Cambridge, England, as a manufacturer of scientific instruments. The company merged with EKCO in 1960. Philips of the Netherlands acquired a majority shareholding in 1967, and later gained full ownership.
Marconi Instruments Limited (MI) was a British company, one of the Marconi group of companies, formerly part of GEC. Originally formed in 1936, there was a buyout of Marconi-Ekco Instruments to form the company Marconi Instruments in 1941.
The Rainbow Codes were a series of code names used to disguise the nature of various British military research projects. They were mainly used by the Ministry of Supply from the end of the Second World War until 1958, when the ministry was broken up and its functions distributed among the forces. The codes were replaced by an alphanumeric code system.
The Dassault Mirage IIIV, also spelled Mirage III V, was a French vertical take-off and landing (VTOL) prototype fighter aircraft of the mid-1960s developed and produced by Dassault Aviation.
AMES, short Air Ministry Experimental Station, was the name given to the British Air Ministry's radar development team at Bawdsey Manor in the immediate pre-World War II era. The team was forced to move on three occasions, changing names as part of these moves, so the AMES name applies only to the period between 1936 and 1939.
Larkspur was the retrospectively adopted name of a tactical radio system used by the British Army. Its development started in the late 1940s with the first equipment being issued in the mid-1950s. It remained in service until replaced by Clansman in the late-1970s although some elements of Larkspur were still in service well into the 1980s. It was widely exported to British Commonwealth armies and other friendly nations.
EKCO was a British electronics company producing radio and television sets from 1924 until 1960. Expanding into plastic production for its own use, Ekco Plastics produced both radio cases and later domestic plastic products; the plastics company became Lin Pac Mouldings Ltd.
The Military Wireless Museum is a private museum operated from Kidderminster, Worcestershire which displays a collection of military wireless equipment from around the world. It developed from the private collection of Ben Nock and marks the importance of wireless communications in the UK and around the globe during World War II and later years.
Air-to-ground communication was first made possible by the development of two-way aerial telegraphy in 1912, soon followed by two-way radio. By the Second World War, radar had become the chief medium of air-to-ground and air-to-air communication. Since then, transponders have enabled pilots and controllers to identify planes automatically, greatly improving air security. Most recently, in addition to sophisticated radio and GPS systems, the unmanned aerial vehicle, or drone, has revolutionised aerial surveillance and combat.
During World War II, aviation firmly established itself as a critical component of modern warfare from the Battle of Britain in the early stages to the great aircraft carrier battles between American and Japanese Pacific fleets and the final delivery of nuclear weapons. The major combatants. Germany and Japan on the one side and Britain, the United States and the USSR on the other. manufactured huge air forces which engaged in pitched battles both with each other and with the opposing ground forces. Bombing established itself as a major strategic force, and this was also the first war in which the aircraft carrier played a significant role.
M-OV was a British manufacturer of thermionic valves. It was a subsidiary of the (British) General Electric Company Ltd.
Red Steer, also known as ARI 5919 and ARI 5952 depending on the version, was a tail warning radar used on the British V bomber force. Built by EKCO, it was developed from the experimental AI.20 radar for the English Electric Lightning. The Lightning required its radar to be remotely installed in the nose of the aircraft, and this made the set equally suitable for remote mounting in the tail of the bombers.
