Introduction R1155 Receiver on top of a T1154 Transmitter.The wireless operator on an Avro Lancaster speaking to the pilot from his position in front of the Marconi T1154/R1155 transmitter/receiver set, circa 1943Inspection of an R1155The '''R1155''' was a British communications receiver, commonly used in aircraft along with its associated '''T1154''' transmitter. It was used extensively by the Royal Air Force during World War II, mainly in larger aircraft such as the Avro Lancaster, Handley Page Halifax, Vickers Wellington and Short Sunderland. Some were also used in vehicles and air-sea rescue launches.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.
