Listening to the Enemy: War Comes to a Cornish Village, St Erth Radio Station 1939-1964 by Michael Griffiths
If you take the road out of St Erth and travel up the hill towards St Erth Praze, you could easily miss, on your right, a dilapidated single storey concrete building. It is in a field close by the edge of the road. This is the guard/generator hut of a very secret and important MI6 Radio Listening Station. Together with its sister sites across the country, it had a profound effect on the outcome of World War 2.
Listening to the Enemy is a fascinating story of the Bletchley Park outstation. Over several years, Mike Griffiths has painstakingly researched the origins and purpose of this site. His father, Harry, was a radio operator at the station throughout the war and he recorded many of his contacts in a little black nook – his ‘Code Book’. This book – full of German and Italian radio nets, brevity codes and Double Agent call signs, encapsulates the role of Bletchley Park; the home of the Codebreakers.
St Erth Radio Station and its sister sites were quite literally the ears of Bletchley Park.
