BT Trial Site. St Albans Radio Station was a point to point radio link run by the Post Office. It was opened in 1926 and it was probably here that Wilkins noted interference by aircraft of radio signals in 1932 which led to development of radar for that purpose. It was used in the Second World War as a listening station feeding coded messages to Bletchley Park for decryption. It was the first station to intercept German radio teleprinter transmissions which were used for the most secret messages. It was later used as a GPO/BT testing ground and closed in the 1960s. It is at present awaiting redevelopment.
