The Direction and Intensity of Waves from European Stations

The deviations of radio goniometric readings from the true bearing of distant and nearby stations were measured at a suitable location with a coil antenna and receiver. In addition to errors due to physical obstructions in the path of the incoming wave, errors varying with the time of day were measured. Radio goniometric measurements were also made during an intense aurera. The intensity of the field of the incoming signals was also measured by means of a resistance network, and the necessary apparatus is described.
