Wireless Set Number 11
The Wireless Set Number 11, or WS No. 11, was a radio set designed for the

Some No. 11s were produced between 1938 and 1940 before they, too, were considered inadequate. A smaller production run in Canada was also completed by
Canadian Marconi and used both by Canadian and British forces. The No. 11 was replaced in tanks by the significantly more capable Wireless Set No. 19, while the No. 11 went on to be used by many others, notably the Long Range Desert Group
.
