    In this paper are discussed certain phases of short-wave telephony, primarily, though not entirely, from the point of view of the transmitter. The field strengths which the transmitting station must provide at the receiver are considered. Typical data are given showing results obtained in transmission from Deal, New Jersey, to England. This is followed by a discussion of requirements and limitatio... View full abstract»

  • A 12-Course Radio Range for Guiding Aircraft with Tuned-Reed Visual Indication

    Publication Year: 1930, Page(s):939 - 962
    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3184 KB)

    This paper describes a directive radiobeacon (or radio range) of the visual indicating type, which has been developed by the Bureau of Standards to provide radio-marked courses at air terminals where more than four airways converge. The radio range is similar in design to the double-modulation type, with the addition of a third amplifier train and accompanying modulation frequency. It provides twe... View full abstract»

  • A Tuned-Reed Course Indicator for the Four- and Twelve-Course Aircraft Radio Range

    Publication Year: 1930, Page(s):963 - 982
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (4272 KB)

    For the 12-course radio range system, in which three modulation frequencies are used, a type of reed indicator has been developed to indicate when the aircraft is on any one of the twelve courses, and if off, approximately how many degrees and whether to the right or left. In addition, it indicates to the pilot in case he becomes lost which is his nearest course, how to turn to get on it, and whic... View full abstract»

    This article discusses networks based upon singly-tuned circuits, and upon coupled circuits with primary and secondary both resonant to the same frequency. Transmission equations are developed and it is shown that for a desired possible transmission-curve shape, the sum of all decrement coefficients must be a certain amount, readily computable for coupled circuits as well as for single circuits.

  • The Establishment of the Japanese Radio-Frequency Standard

    Publication Year: 1930, Page(s):1017 - 1027
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2256 KB)

    This paper describes the standard frequency equipment established at this laboratory. A valve-maintained tuning fork of Elinvar steel, made by H. W. Sullivan Co., Ltd., London, has been taken as the working standard. Some of the important characteristics of its frequency variation have been measured and adjustments have been made in order to minimize the variations which have been observed. The ab...

  • The Amplification and Detection of Ultra-Short Electric Waves

    Cited by:  Papers (3)

    In this paper, experimental results and theoretical considerations are discussed which concern the amplification and detection of electric waves shorter than one meter in length, in a system wherein diodes and triodes are connected so as to produce oscillations of the Barkhausen and Kurz type. A simple theory of the electronic effect in the detector action is given. In some of the circuits use is ... View full abstract»

  • The Radio Engineer and the Law

    Publication Year: 1930, Page(s):1038 - 1043

    This paper presents the difficulties inherent in the development of a body of law for radio. It points out that that body of law must be based upon sound scientific principles as presented by radio engineers. The radio engineer as an expert witness may be able to avoid the difficulties encountered by experts of other classes and take advantage of important opportunities for the education of courts...

  • Note on Variations in the Amplification Factor of Triodes

    Publication Year: 1930, Page(s):1044 - 1046
    Cited by:  Papers (1)

    It is pointed out that variations in the amplification factor of triodes are due to different portions of the tube having different values of μ. The resulting μ variations over the operating range of the tube characteristic are very considerable in commercial tubes, and give numerous undesirable operating features. View full abstract»

  • Radiotelegraphy and Radiotelephony on Half-Meter Waves

    Publication Year: 1930, Page(s):1047 - 1063
    Cited by:  Papers (8)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3264 KB)

    Communication tests in radiotelegraphy and radiotelephony on half-meter waves are described. The first section of the paper is devoted to the description of a new type of receiver for 40-80-cm waves. Experimental results are given to show the action of this receiver. It is pointed out that a sort of regenerative amplifying accompanies the detection of such extremely short waves, and a brief explan... View full abstract»

  • The Effect of Rain and Fog on the Propagation of Very Short Radio Waves

    The purpose of this paper is to investigate theoretically the effect of rain, fog, or clouds on the propagation of short raidio waves. The theory of the propagation of electromagnetic waves in a medium in which are suspended spherical particles of an arbitrary material is first reviewed. The available physical data on fog and rain is then referred to. The conclusion is arrived at that for waves gr... View full abstract»

    (1) The received field intensity was less affected by the variations of the meteorological elements in the environs of transmitting stations than by those of the receiving station. (2) The field intensities for both daylight and night reception varied inversely with the changes of atmospheric temperature and absolute humidity on the receiving side. This was in agreement with the daylight results o... View full abstract»
