Re: Lets hear it for the girls
I don't see any mention of the magnetron which was another British invention. The early RADAR frequency was in the OH (water) band and didn't perform as well as it could have. This is perfect for a microwave oven though. The Germans captured some magnetrons but couldn't get them to work very well because they made them perfectly symmetrical.
England also set up several "fake" radio transmitters outside of London to try to mislead the Germans.
