Amateurs called to serve
At the outbreak of the Second World War, the Radio Security Service sought help in detecting and monitoring clandestine radio communications. Through the RSGB, experienced radio amateurs were recruited for their strong Morse and receiving skills.
The quiet work of listening
Many Voluntary Interceptors operated from their own homes. They monitored, copied and submitted traffic, contributing to a wider intelligence operation. Their work required discipline, confidentiality and the ability to distinguish meaningful signals from a crowded radio environment.
A distinction worth preserving
The Voluntary Interceptors were connected with the Radio Security Service and were not simply another name for every military Y-station operator. Their role is particularly relevant to the amateur radio community because skills learned as a hobby were applied in national service.
A legacy of service
The RSGB records a memorial recognising the contribution of around 1,500 Voluntary Interceptors. Their story speaks to the value of learning a craft properly long before anyone knows where that skill may be needed.
