    The principles underlying automatic frequency control of the oscillator in superheterodyne receivers have been outlined in previous papers given before the Institute of Radio Engineers. This paper deals with simplification and improvements in operation of frequency control circuits and their application to automatic (electronic) tuning control. A new type of "discriminator" which differentiates be... View full abstract»

    Simultaneous radio range and telephone service has been in demand on the airways of the United States for several years. A simple method of obtaining this service has been developed and is now being gradually applied to the airways. Various methods of obtaining simultaneous service are discussed. The effect of linear and square-law detection used with single side-band and double side-band transmis... View full abstract»

    This paper discusses from a theoretical standpoint the various types of frequency errors in thermal ammeters, describes methods of calibration of current measuring instruments at radio frequencies, and furnishes some data as to the accuracy of certain commonly used instruments at frequencies up to 100 megacycles. Frequency errors are determined in the low range instruments and in the high range in... View full abstract»

    The following discussion deals with a graphical method for designing an intermediate-frequency transformer for variable selectivity using the method of varying the coupling. A brief theory of the graphs precedes the application of the graphs to an actual problem. View full abstract»

    The penetration of ultra-short-wave radiation beyond the range of optical sight is dependent on the diffraction and refraction of the rays. Proceeding from an analogy to optics the diffraction is calculated by various methods. It is found that calculation of the ray distribution beyond the line of sight yields the best agreement with measurement. The practical application of the results of calcula... View full abstract»
