Abstract :
The radio interference situation is rapidly becoming so serious as to make improvements in both methods of detection and methods of elimination absolutely imperative. The most effective method in interference detection is that combining the good features of the intensity method, with the circuit selection features of the directional method, coupled with extensive experience, both in the field and in the laboratory. A light, self-contained, compact, unidirectional receiver equipped with a visible indicating audibility meter is the proposed instrument most desired for this work. The design of filter systems intended to drain interference from circuits should incorporate suitable impedances at points where reflection is likely to occur.
