Last year Verlulam ARC enjoyed a talk given by John Alexander, G7CGK, on mechanical cipher machines. This WWII theme continued with a lecture by Stan Ames, G4OAV, entitled Secret Wireless Operations in St Albans during WWII. Stan's presentation described the development of the network of secret wireless stations that intercepted enemy transmissions during WWII and subsequently decrypted at Bletchley Park. The story began with a Post Office radio station at St Albans that was secretly reporting German wireless traffic to the Foreign Office in 1932. By the end of 1938, the military authorities asked the Post Office to set up a network of eavesdropping stations -the first of which was built at Sandridge near St Albans.
