The Type R1155 Receiver was based on a Marconi design from the 1930s and modified for RAF bomber and Coastal Command operations. This first entered operational use in 1940 and more than 80,000 equipment sets were manufactured during the war years. The various designs were spread to five other radio firms, including Ekco, Plessy, Philips, and the Gramophone Co. (EMI), but were overseen by the Marconi Company. The R1155 is a combined communicatrion and direction-finding receiver; it was commonly used with the T1154 Transmitter which provided a number of spot frequencies. It was provided with a headphones output only and was powered externally by the aircraft electrical systems. The equipment continued in service on many civil aircraft, and the receiver was popular with radio enthuisasts & hams after the war.
