    This paper presents a critical résumé of the performance of apparatus employed for radio direction determination either by transmission or by reception. After an historical summary of results obtained in various parts of the world, a brief description is given of the fundamental principles underlying radio direction-finding. In this section attention is drawn to the application of the pr... View full abstract»

  • Some Experiments in Short Distance Short-Wave Radio Transmission

    Some experiments in short-wave radio transmission over a distance of 55 miles are described, the results of which are interpreted to indicate the presence of strong "sky" waves, with "ground" waves of negligible amplitude in comparison with the "sky" waves as received. Upon decreasing the transmitter wavelength, at a given time of day, a minimum wavelength was reached below which no communication ... View full abstract»

  • Wireless Telegraphy and Magnetic Storms

    A recent theory of auroras and magnetic storms attributes these phenomena to the action of a flash of ultraviolet light from the sun. The flash causes an unusual ionization in the Kennelly-Heaviside layer. Therefore, it is only daylight wireless circuits which are, or may be, disturbed at the commencement of the magnetic storm, the night circuits remaining normal until dawn when they may be distur...

    Major electrical elements of a modern superheterodyne receiver-tuned radio-frequency amplifier, intermediate frequency amplifier detector and audio-frequency amplifier-are briefly discussed in light of recent developments. A practical automatic volume control is described. Curves illustrating the major performance characteristics of the receiver are shown. View full abstract»

    The substitution method commonly employed for measuring small capacities is shown to be a special case of a more general principle. As other special cases of this principle methods are presented for simultaneously measuring inductance and capacity when joined in series and when joined in parallel. The cases discussed indicate the method of application of the general principle to any type of measur... View full abstract»

    A type of alternation phonometer has been developed which permits rapid switching of power at two frequencies to the same loudspeaker without the distracting effect of the transients that would result from ordinary types of commutation. This result is obtained by the use of rotating condensers to provide variable capacitative reactance in the input circuit of the power amplifier that operates the ... View full abstract»

    A facsimile picture transmitting system is described. The chief object of the design of this system was to produce a simple, rugged apparatus for practical usage, which would not require the attention of a skilled operator. The system does not require a special preparation of the original, and the receiver records the copy directly on the photographic paper. The usually delicate problem of photo-c...

    A dynamic method of finding ∂2ig/∂eg2or ∂kg/∂eg, the main term in grid-circuit rectification, is given. This method is based upon formulas given by Chaffee and Browning and consists in calculating ∂kg/∂egfrom the change of d.c. when a known a.c. input voltage is applied to th... View full abstract»

    In this paper a new method proposed by Brillouin for the calculation of radiation resistance is applied to several types of beam antennas. New formulas are deduced and some interesting results are obtained showing the distribution of the radiated power among the different wires of beam antennas and giving the numerical value of the radiation resistance in various cases (synphase antenna, antiphase...
