    The paper describes measurements on the daylight radio field intensity produced in San Diego, California, by the arc stations at Cavite, Philippine Islands, 11,800 km., and Malabar, Java, 14,700 km. distant. These distances are nearly twice as great as any previously studied, except for a few scattered measurements. The average observed intensities were, from Cavite 2.04 μ v./m.., and from Ma...

    As an introduction, details of tube design are discussed, together with a partial list of the sizes studied. A resume of the general theory of magnetic control is then given. The first part of the paper is taken up with the application of the magnetron as an amplifier at 8,000 meters wave length. The circuit is described and the results of tests on tube impedance, design of control coils, the vari... View full abstract»

    An improved method has been developed for standardizing a wavemeter by means of the harmonics produced by a simple type of harmonic generator the fundamental of which is an audio-frequency alternating current. The arrangement is adapted to primary frequency standardization since the fundamental frequency can be checked during the measurement against the frequency of a standard tuning fork by means...

    The author criticizes the existing methods for the measurement of radio frequency resistance and describes a new electrometer method, where a quadrant electrometer is put across the inductance in an oscillatory circuit. The condenser of this circuit is charged to the voltage V0and discharged thru the inductance by means of a special key. The throw of the electrometer will then be propor... View full abstract»
