Beeston Hill Y Station : ウィキペディア英語版 | Beeston Hill Y Station
Beeston Hill Y Station was a secret listening station located on the summit of Beeston Hill, Sheringham in the English county of Norfolk.〔''OS Explorer Map 252 - Norfolk Coast East''. ISBN 978 0 319 23815 8.〕 The chain of Y stations were the front line of the War Office’s Bletchley Park, which had the code name station X. ==Description== This Y Station was a specially constructed wireless interception facility which was also used for direction finding on enemy wireless transmissions. This became particularly important in the Battle of the Atlantic (1939–1945)〔(【引用サイトリンク】title=The Bitter End, The U-boat War, 1943-1945 )〕 where locating U-boats became a critical issue. Admiral Dönitz told his commanders that they could not be located if they limited their wireless transmissions to under 30 seconds, but skilled Direction finding operators were able to locate the origin of their signals in as little as 6 seconds.
