    In this paper a brief review is given of recent engineering progress in various classes of mobile communication. The principal applications of radio in the mobile services are in the marine, aviation, and police fields. Improved circuits, new tubes, more advanced mechanical design, and better knowledge of the characteristics of short waves have all contributed to a greater extension of mobile radi...

  • Some Data concerning the Coverage of the Five-Megacycle Standard Frequency Transmission

    Publication Year: 1935 , Page(s): 448 - 453
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (672 KB)  

    Beginning in January, 1931, the Bureau of Standards has transmitted a standard frequency of 5000 kilocycles per second each Tuesday for two hours during the day and two hours at night. These transmissions have for their purpose the furnishing of an accurately known frequency to the public. They are used especially for calibrating the frequency standards of the field offices of the Federal Radio Co... View full abstract»

  • The Eclipse of August, 1932, Observed by Radio Facsimile

    Publication Year: 1935 , Page(s): 454 - 460
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (2120 KB)  

    In connection with the eclipse of August, 1932, a good deal of interest was shown in the theory of the corpuscular shadow which was expected during the two hours before the optical eclipse. A radio receiving station equipped to take continuous facsimile records of a signal from Schenectady was therefore set up at Conway, New Hampshire. The records showed a marked change in conditions during the pe... View full abstract»

  • Notes on Propagation at a Wavelength of Seventy-Three Centimeters

    Publication Year: 1935 , Page(s): 461 - 469
    Cited by:  Papers (7)
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (1448 KB)  

    Quantitative field strength observations have been made on a wavelength of 73 centimeters with improved apparatus. The methods are described. Propagation data have been obtained with the receiver installed in an automobile and an airplane. Further observations were made on the ground at a distance of 113 miles, 8000 feet below the line of sight from the transmitter. The results show the nature of ... View full abstract»

  • Radio Propagation over Spherical Earth

    Cited by:  Papers (1)
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (1184 KB)  

    The paper shows how Watson's solution for the propagation of electromagnetic waves over perfectly conducting spherical earth merges into the Abraham solution for propagation over a perfectly conducting plane for shorter distances. The effects of refraction by the lower atmosphere and of the imperfect conductivity of the earth are taken into consideration. The magnitude of the former, which is appr... View full abstract»

  • Series Modulation

    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (2232 KB)  

    In this paper it is pointed out that the type of modulating system used in any given case depends to some extent upon the particular type of service involved. The limitations of existing types of control are discussed, and a detailed theoretical and experimental investigation of the so-called series type of modulation is reported. Operating data, in the form of graphs, are presented for those exis... View full abstract»

    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (1432 KB)  

    A mathematical analysis of the plate-current flow in class B and class C radio-frequency power amplifiers is presented, due consideration being given to the nonlinearity of the tube characteristics and the discontinuity of plate-current flow. A simple and highly approximate equation for the fundamental harmonic component of amplifier plate current in terms of the applied continuous and alternating... View full abstract»

  • The Detection of Frequency Modulated Waves

    The comparative ease with which pure frequency modulation can be produced in electron oscillators at ultra-high frequencies has led to an examination of the problem of detecting a frequency modulated wave. In this region of frequencies the high ratio of frequency shift to modulating frequency gives rise to a very large number of side bands in the spectrum representing the modulated wave. Detection...
