Post Office Radio Service

The Radio Service was also known as the Radio Investigation Service – or simply RI. The Technical Officers who did the work were known as Investigation Officers. The main work of the Radio Service was the tracing and prevention of interference to broadcast radio and television services. Prevention could mean repair or the fitting of suppressers. Repair would be carried out by a maintenance company but suppression could be done by the Investigation Officer. The other areas of work were tracing interference to Private Mobile Radio-telephone services (PMR) such as those used by taxi firms, utilities and the emergency services, the inspection and control of Radio Amateurs and the location and prosecution of pirate radio stations.

When the Post Office became government owned the work was still done, but on behalf of the Home Office who paid costs plus 2%. When BT became a PLC then the Home Office took over the work with many BT staff transferring back to the Civil Service. The Home Office replaced the Bedford vans with Morris Marina cars.
