As a radio amateur and collector of ww2 radios, I became interested in radar. Alas, the sets that were abundant during the 50's, abundant and cheap, are now gone. As to your question: show your father Louis Brown's "A radar history of world war 2, technical and Military Imperatives" (ISBN 0 7503 0659 9, 1999 Institute of Physics Publishing, Bristol and Philadelphia), and he will surely start telling you his stories!
