The Searchers: Radio Intercept in Two World Wars
Cassell | 2003 | ISBN 0304365459 | English | 288 pages | PDF | 151 MB
With the renewed interest in wartime intelligence, a timely history of radio intercepting answers the question of how enemy messages are detected in the first place. The focus is on the early war-shortening Y and Radio Intercept Services, and their brilliantly clever inventors and technologists who proved to be unsung heroes with headphones clamped to their ears.
