Title: A new technique for obtaining the spectral analysis of atmospherics arriving from particular directions
Description: This paper describes the fundamentals of basic equipment employed in a new system designed to measure VLF attenuation rates using atmospherics. New techniques were developed to record the spectral components of transient signals arriving from within an adjustable azimuthal sector. The apparatus was operated during several periods of high thunderstorm activity to determine its accuracy and dynamic range.
