    A preliminary range chart has been constructed for telegraphic communication, 5 kw. in the antenna, at various frequencies. The conclusions upon which the range chart is based are derived from experiments made by the Naval Research Laboratory, from experiments made by amateurs, and upon such data as the Laboratory has had access to from commercial and Government sources at home and abroad. An atte... View full abstract»

    The paper discusses methods of combining the signal currents from the different antennas in a directional receiving system and a detailed description is given of a system by which all phase and amplitude adjustments are performed upon the beating current inputs of a double detection receiver. The theoretically derived shape of the directional characteristic of a two-loop system has been verified b... View full abstract»

    This paper shows some of the defects of present theories regarding regeneration and presents a new method of analysis based on the idea of a power balance. It is shown that a signal voltage does not supply power to a regenerated circuit but merely prevents certain losses from occurring. This upsets the balance between power input from the tickler and power lost in the circuit, so that oscillation ... View full abstract»

    Representative designs of large air core antenna tuning inductances are described, in types suitable for outdoor and indoor service. The latest improved designs are described in greater detail and compared with earlier designs on a basis of efficiency and kilovolt-ampere capacity. Formulas are given for calculating the ohmic and eddy current conductor power factor of coils using finely stranded, s... View full abstract»
