    Westinghouse Radio Station KDKA, at Saxonburg, Pa., was built to provide up-to-date equipment for regular broadcasting and for high power experimental work on either long or short waves. Power equipment consists of a 12-phase, 900-kw, 30-kv rectifier using three-anode mercury pool type tubes; a 6-phase, 450-kw, 22-ky rectifier; four 10-kw, 3-kv motor generator sets for bias and intermediate amplif...

    In the first part there are mentioned two modulation connections that have been found suitable for modulation with one high frequency or with several high frequencies. It is stated that by careful screening of the parts carrying high frequency, it is possible to prevent direct high-frequency radiation. The question of the pro-component for the permissible degree of balance is discussed from the vi... View full abstract»

    A frequency measuring system is described wherein transmitter frequencies are accurately compared with the harmonics from a precision, piezo-electric frequency standard. Through the medium of a system of multivibrators and a synchronous clock the frequency of the standard oscillator is referred to the time interval defined by the rotational frequency of the earth. Harmonics from a 100-kc crystal o... View full abstract»

    A new circuit for the generation of ultra-short-wave electronic oscillations is described. This circuit consists of two tubes connected by symmetrical plate and filament Lecher systems instead of the usual plate-grid arrangement. The wavelength of the oscillations is determined by the length of the plate Lecher circuit. The tuning of the filament Lecher system governs the amplitude of the oscillat... View full abstract»

    The Campbell-Shackelton shielded ratio box is intended to serve as the nucleus of a one-to-one bridge for the comparison of impedances. The transformer used in it operates effectively over the range from 50 to 50,000 cycles per second and in that range the limit of error is considered to be the greatest one of the three following terms: (1) ±0.01 ohm (resistance, inductive, or capacitive reac...

    The equivalent input resistance of a grid leak and condenser in parallel and the combination in series with a diode or the grid-cathode circuit of a triode are calculated for various combinations by means of the static Ig-Eg, characteristics and an extension of the work of Colebrook and Peterson and Llewellyn. The equivalent internal resistance of the diode is also calculated... View full abstract»

    Expressions for the self and mutual impedances within a radiating system are developed by the use of the generalized reciprocity theorem. These expressions are given in terms of the distributions of the electric field intensities along the radiators. A method for the determination of the field intensities is outlined. Formulas for the self and mutual impedances in several types of directional ante... View full abstract»

    The problem of transmission of periodic waves along a transmission line, whose series impedance and shunt admittance per unit length very as any powers of the distance from some point, is solved. The solution is given in terms of Bessel functions. A length of such a line is considered as a four-terminal network, and the more important parameters of the network are given. From these parameters one ... View full abstract»
