  • Hot-cathode mercury rectifier tubes for high power broadcast transmitters

    Publication Year: 1935, Page(s):103 - 111

    This paper describes the new and large hot-cathode mercury-vapor rectifier tube that is used in the plate power rectifier of the Crosley (WLW) 500-kilowatt broadcast transmitter. Design features resulting in improved operation of mercury-vapor tubes are discussed together with the operating characteristics. An analysis of the advantages of the unit half-wave type of rectifier tube is made. View full abstract»

  • A method of measuring noise levels on short-wave radiotelegraph circuits

    Publication Year: 1935, Page(s):128 - 131

    This method is essentially a means for continuously measuring the percentage of elapsed time during which the noise level exceeds a certain predetermined voltage level. The predetermined voltage level may be made any level at which data are desired. The device consists of a biased tube circuit such that when input signal exceeds a certain level, the output tube passes a normal value of plate curre... View full abstract»

  • The ionizing effects of meteors

    Publication Year: 1935, Page(s):132 - 149

    It is shown that a meteor of average velocity has enough energy to cause ionization of atmospheric gases by impact. Recent experimental work by Frische and others on collisions of ions is interpreted as supporting the hypothesis that meteoric collisions do result in ionization. The afterglow of nitrogen is considered as a possible example of the process by which a meteor train remains glowing for ... View full abstract»

  • On the impedance of a vertical half-wave antenna above an earth of finite conductivity

    Publication Year: 1935, Page(s):150 - 167

    The complex impedance of a vertical half-wave antenna located any distance above an earth of given conductivity and dielectric constant is calculated by the “induced electromotive force” method. Based on the assumption k0≪ |k| (where k0 and k are the wave numbers for the atmosphere and earthy respectively), the results are applicable down to... View full abstract»

  • The phase and magnitude of earth currents near radio transmitting antennas

    Publication Year: 1935, Page(s):168 - 182

    This paper deals with various electrical magnitudes involved in the process of radiation from an ordinary antenna. The calculations presented are based on the simplified assumptions of a highly conducting earth and a sinusoidal distribution of antenna current. Also, they neglect any components of the near-by field that may be associated with the flat top. The paper is divided into four main parts ... View full abstract»
