Abstract :
Various types of radio transmitting equipments are described, ranging in output from 200 to 2000 watts. The application of master-oscillator power-amplifier circuits for low-and medium-frequency transmitters is explained, and the uses of quartz crystal control for high-frequency and broadcast transmitters are described. A brief explanation is also given of the equi-signal system of radio beacon transmission, which promises to become an important aid in the navigation of aircraft.
