In 1940 a government radio station was established at Signal Hill and this was extended a year later, the increasing number of military personnel living in Gawcott and the surrounding villages. The shortwave radio transmitters were used to broadcast highly secret ’black’ propaganda programmes which were made at Milton Bryan Bedfordshire, and the Gawcott facility also worked in conjunction with facilities at Potsgrove, Hanslope and Bletchley Park. The station remained operational, apart from a period of dormancy in the 1970s, until it was closed and sold in 1994.
