Special thanks to Clifford Heath for his help putting together the radio demo, and the folks at the Victorian ARDF group for connecting us.
Thank you to Brian Harrison and Michael Murphy with the AWA Communication Technologies Museum for their assistance with early research.
Thank you to Peter Bevelacqua over at Antenna Theory for help filling in some missing details.
Sharp-eyed viewers might notice there doesn't seem to be a loop antenna in the flight simulation shots. It sadly wasn't included in the simulator's model of Earhart's Electra, but it features prominently in old photos.
