I don't know who invented it, but when I learned to fly, it was the primary nav aid other than an ADF. The Champs I were flying had a battery operated 200-400 KC receiver that was used to pick up the radio range.
When I got to fly an IFR airplane that had an ADF I was able to listen to the radio and fly to music. What a luxury! I remember as a 16 year old flying over the San Fernando Valley in California, listening to "Paddling Madeline Home". When I got active again I mentioned something about the "cone of silence" to my instructor. The young whipper snapper didn't know what I was talking about. <G> Cheers: Paul N2409H > > SUNDAY TRIVIA QUESTION > The very first aerial radio navigation was the LF radio which used an "A" > and "N" quadrant and a "NULL" on the centerline.
