    The use of cathode ray tubes for television reception involves problems not encountered when the tubes are used for oscillograph work. This paper takes up various constructions which were tried showing the characteristic curve of each as well as the behavior of the spot under various conditions. It was found that it was possible to design a tube which would operate with a negative bias on the focu... View full abstract»

    In the application of cathode ray tubes to oscillographic measurements, certain factors affect the accuracy of the results. The most important of these items are discussed and methods outlined whereby the effects of this distortion can be minimized or compensated for. A description is included of several oscillograph tubes, and associated apparatus, in which simplicity of operation is a feature. View full abstract»

    Extensive measurements have been made of the field distribution about a vertical antenna operating at 29 megacycles over sea water. With the help of a small, nonrigid airship observations were made at various altitudes which permitted the plotting of the space characteristic and the determination of the attenuation as dependent on altitude. The experimental results are compared with field intensit... View full abstract»

    A device for making a continuous record of the energy received from a signal or from static is described. Simple modifications are suggested by means of which peak or average voltage may be recorded. View full abstract»

    A system for recording the direction of arrival and intensity of static on short waves is described. The system consists of a rotating directional antenna array, a double detection receiver and an energy operated automatic recorder. The operation of the system is such that the output of the receiver is kept constant regardless of the intensity of the static. Data obtained with this system show the... View full abstract»

  • The Ionizing Effect of Meteors in Relation to Radio Propagation

    Cited by:  Papers (8)

    From a study of available meteor data it is concluded: (1) that meteors expend the larger part of their energy in the Kennelly-Heaviside regions, that is, in the regions of the upper atmosphere which control the propagation of all long-distance radio waves; (2) that the major portion of a meteor's energy goes into ionization of the gases around its path; (3) that this ionization extends to a consi...

  • Observations of Kennelly-Heaviside Layer Heights during the Leonid Meteor Shower of November, 1931

    Publication Year: 1932, Page(s):1941 - 1945

    This paper describes the results of radio measurements of the virtual heights of the Kennelly-Heaviside layer during the Leonid meteor shower of November, 1931. While the results are not conclusive, due to the fact that a moderate magnetic disturbance occurred during this same period, there is some reason to believe that the presence of meteors in unusual numbers causes increased ionization of an ...

  • Some Notes on Demodulation

    The audio output of a detector depends upon two magnitudes which are independent each from the other. These magnitudes are the radio-frequency envelope of the input and the rectification characteristic of the detector. In problems dealing with the distortions caused by selective circuits or by the superposition of several modulated signals it becomes necessary to treat both magnitudes separately. ...

    If two modulated radio frequencies are added, the envelope of the resulting signal can be found by means of a vector diagram. A number of envelopes corresponding to various conditions are shown. The distortions in the resulting envelopes are mainly due to phase shifts of audio frequency. Low percentage modulation helps to keep distortions small. The treatment applies to common-frequency broadcasti... View full abstract»
