- Reactance Coil, Used at Hammond Radio Research Laboratory, 1915-1920 - John Hays Hammond, Jr., is considered "the father of radio control." In 1926, he built a medieval-inspired castle in Gloucester, Massachusetts, as his home and research laboratory. With 400 patents to his name, Hammond developed radio control, autopilot function, and targeted missile detonation. A reactance coil is an inductor, blocking high-frequency AC power, allowing low-frequency DC power to pass.
