    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.
