    The paper gives the results of field intensity measurements at the Bureau of Standards on the transatlantic radio stations at New Brunswick and Tuckerton, New Jersey. The summer measurements are somewhat weaker than those of winter and generally the afternoon signals are slightly weaker than those of the forenoon. The most interesting fact observed was the great increase in signal strength which a... View full abstract»

    A brief history of short wave broadcasting as carried on under the direction of the author is given, together with the difficulties encountered and the results obtained. The transmitter and receiver employed experimentally for repeating KDKA's programs from KDPM at Cleveland are described. The high power short wave transmitter at 8 XS (Pittsburgh) is described particularly in regard to the radio f... View full abstract»

    The general arrangements of the broadcast transmitting stations established by the Radio Corporation of America in New York and Washngton, D.C. (U.S.A.), are described. The station and portable apparatus, with wiring diagrams and frequency characteristics, are shown. Each station has an associated local wire line network, for broadcasting from points outside the studio, and long distance lines int... View full abstract»

    Piezo-electric wave length standards of the quartz or quartz-steel types previously described by the author have been compared with standard wave meters or multi-vibrators in the United States, Italy, France, and England. Six standards were used, of frequencies ranging from 14 to 1,500 kilocycles. The methods of comparison are described, and data obtained at the various laboratories presented. The...

    The above paper describes briefly calculations required in the parallel wire system used by the Bureau of Standards for radio frequency standardization. Formulas involving a correction term are given by means of which the standard frequency can be calculated from the distance between two consecutive maximum settings along the parallel wire system. A numerical example is added, showing the magnitud... View full abstract»

    In this paper, the radiation resistance of a filamentary vertical antenna erected over perfectly conducting plane earth is calculated for wave lengths down to 0.3 of the fundamental. Pierce's assumption of sinusoidal variation of the current amplitude along the antenna forms the basis of an application of the methods of the electron theory, whereby the e.m. potentials are found by integration and ...

    This paper considers the idealized problem of the transmission from a perfect vertical antenna over perfectly conducting plane earth. The distribution of current amplitude along the antenna is assumed to be sinusoidal. The antenna resistance is entirely radiational and has been calculated in a companion paper. The amount of energy radiated in various altitudinal directions is calculated, and distr... View full abstract»

    The source of power losses in a condenser may be considered as a resistance in series or in parallel with the condenser. If the resistance is considered as in series, the capacity must be considered as the effective capacity, and the power factor is given by a simple formula. If the resistance is considered as in parallel, the capacity must be considered as a pure capacity, and knowing the pure ca... View full abstract»
