An Aircraft Radio Receiver for Use with Rigid Antenna

An outline is given of the physical and electrical requirements of an aircraft radio receiver suitable for the reception on a rigid antenna of radio beacons and weather service. The design of a special unicontrol receiver calculated to fulfill these requirements is described, Quantitative performance data are presented, with particular attention to the problem of detector overloading when operating a visual indicator from a beacon of the Bureau of Standards type. The corroboration of these data by practical tests is briefly discussed. The paper is concluded with quantitative discussion of the problem of ignition shielding on a particular type of airplane motor.
