The Western Electric SCR 68 came out in 1918. It was used in airplanes during World War I. The set could both transmit and receive. A reel of antenna wire with a counter was used as the antenna. The pilot would trail the amount of antenna wire needed for the transmission frequency and had to remember to reel back in the plane the antenna wire before landing—and also hope the trailing antenna wire did not get tangled up in the ailerons.
