The Searchers

"Kenneth Macksey's book reveals how radio technology shaped the course of the Second World War. This is the story, not of the codebreakers, but of the Y Service, the searchers who made their vital work possible: men and women with headphones clamped to their ears who for hours on end searched the radio bands, sometimes in dangerous places, in order to overhear the enemy. Their achievements were made possible by brilliantly clever inventors and technologists, constantly pushing forward the frontiers of knowledge. The intelligence derived from their work influenced, often determined, the course of battle in the global war against the Germans, Italians and Japanese, and Kenneth Macksey shows just how vital were these unsung heroes who spent their war in the shadows." --Book Jacket.
