The last topic in Terman`s 1955 opus is "Radio Direction Finding". On
page 1048 Terman writes: "This behavior (simulated sense antenna) causes
a signal to be delivered to the receiver even though the loop ts in the
position for zero response;"

I have a friend, N5CPA, who was a B-24 bomber pilot flying out of Italy
to bomb Austria and Germany as WW-2 was ending. They had a direction
finding station in North Africa to advise them of their positions when
needed. Problem was, Germans often answered first with wrong location
and direction in impeccable American English so Americans might exhaust
their fuel.

Walter Maxwell worked for the FCC at war`s end in Hawaii and equipped
himself with an Adcock antenna so he could advise lost American aviators
of their positions in the Pacific. I think Walter has published his
story in a radio magazine.
