RSGB and Voluntary Interceptors

At the outbreak of WWII in 1939 MI5 established a unit known as the Radio Security Service (RSS) to detect and monitor enemy radio transmissions.

These volunteers became known as the Voluntary Interceptors.

So vital and distinguished was the role of the RSS that it eventually became part of the overall Secret Intelligence Service (SIS).

Voluntary Interceptors memorial plaque at the NRC

At the NRC there is an interactive presentation which contains the names of many VIs, describing their historic role, the equipment used and the resulting product.

Find out more about the VIs and watch a trailer for the NRC presentation on the RSGB website.
