Quoting Hipper ; Did the Enigma decodes have an input in the Battle of Britain?
I was told, much later, by an RAF ground wireless intercept operator, that they listened to various frequencies used by the Luftwaffe in France. The aircraft there, prior to a mission, tuned and checked their radios which, while brief activity, could give indications of the numbers of aircraft involved, and by the use of D/F, the airfields where the activity was taking place. It may not have been much use in the context of Enigma, but it was useful in giving warning of the numbers of aircraft which could be expected, and given good intelligence, the units involved.
