Colour photograph of a Navy ‘Wasp’ helicopter taking off from the Decca HIFIX caravan at Aird, Cornaigmore, in 1970. HIFIX stations were located at several spots in the Hebrides for relaying messages to/from survey vessels at sea, which were recording the topography of the ocean floor. The Navy had sent personnel ashore by helicopter to lay a cable from the mains electricity suppy to the caravan, in response to a complaint by the occupier of the house, Mr A Campbell, about the noise made by the caravan’s generator.
Colour photograph of the Decca HIFIX mast and caravan next to the house at Aird, Cornaigmore, in 1970. HIFIX stations were located at several spots in the Hebrides for relaying messages to/from survey vessels at sea, which were recording the topography of the ocean floor. The house in the photograph was occupied by Mr A Campbell, who “complained about the generator noise. He had spent his life at sea in engine rooms and thought he deserved a peaceful retirement”. As a consequence, a cable from the caravan was connected to the mains electricity supply. Includes additional emailed information.
