The Sieg Transmitter was a device used by Nazi Germany during World War II. Having acquired a piece of Chronosteel, a group of Nazi soldiers led by Koenig and Miss Wyckham planned to use it in conjunction with the Sieg Transmitter to block Little Malding's early warning radar, paving the way for a German invasion of Britain. They were thwarted on 7 June 1941 by Clyde Langer and George Woods, who removed the Chronosteel from the transmitter at St Michael's Church. (TV: Lost in Time)
