    The Wireless Set No. 11 as a successor to the Wireless Set No.1 which was too complex for mass production, was developed in 1936 in collaboration of the SEE and E.K.Cole, a first batch of 20 sets were produced for trials in 1937.
    Production models were delivered from 1938, production numbers reached around 19000 sets in 1942; the Wireless Set No.11 was the backbone of short range communications of the British Army in early WW II together with the Wireless Set No.9. A large number of Wireless Sets No.11 have been captured by German troops when the British Expeditionary Corps had to retreat back from France in 1940.
    The successor of the sets were the Wireless Set. No.19 for use onboard tanks and the Wireless Set. No.21 as ground station and for non-AFV use.
