Abstract :
A radio direction finder is described which uses a crossed-loop collector system, electronic switch, single superheterodyne receiver, and synchronous rectifier to produce an instantaneous unidirectional visual indication of the direction of arrival of an electromagnetic wave. Design data and operating characteristics are considered, with details given of the new components.
