    The results of one year's observations of the signal strength at Washington, of the Lafayette Station (23,400 m.) and the Nauen Station (12,500 m.) and of atmospheric disturbances are given in tabular form and discussed. The relative usefulness of these two wave lengths for continuous communications is analyzed. View full abstract»

    The paper describes one method of establishing frequency standards employed by the Bureau of Standards which is based on the direct measurement, in linear measure, of the wave length of very short standing waves on a pair of parallel wires. The wave lengths measured were from 9 to 16 meters, the currents having frequencies from 33,000 to 19,000 kilocycles per second. The apparatus for generating t... View full abstract»

    After describing the commonly employed absorption and constant current systems of radio telephone modulation, the author discusses a system of modulation wherein the resistance in the grid circuit of the power oscillator tubes is vocdly varied, this resistance being itself the plate circuit of a suitable vacuum tube. Operating data on sets embodying this method are given. View full abstract»

    After analyzing the design considerations for high voltage radio frequency continuous wave antenna insulators, there are given data on the heating, losses, and flashover points of a number of sizes and forms of porcelain rod insulators, both dry and wet. The effect of rain shields, electro-static strain shields, and "breathers" on the behavior of the insulators is discussed. The voltage distributi... View full abstract»

    Chapter VI. In the "master oscillator" or "power amplifier" circuit oscillations are generated by a small power source and then amplified. In the amplifier there is no definite phase relationship between plate and grid potentials. The phase is determined by the tuning of input and output circuits. The effect of variations in grid and plate circuit tuning upon output and losses is developed for bot... View full abstract»
