    The paper presents the results of a quantitative study of radio distribution in and about the cities of New York and Washington, District of Columbia. The wide variations of attenuation over different kinds of territory, the causation of radio shadows or dead spots, and the phenomena of refraction and diffraction are all illustrated by the data and curves. Radio field strength contour maps of the ... View full abstract»

    The paper deals firstly with the early forms of quadrodes or four-electrode tubes and leads up to a complete description of the Marconi type of quadrode or F. E. I. type and the attendant amplifier circuit. The amplifier described utilizes one F. E. I. tube and effects a one-stage radio frequency, a rectification, and a one-stage audio frequency. Information is detailed as to the practical experie... View full abstract»

    (1) Experimental: By means of a vacuum tube oscillator to operate a loud speaker unit and a calibrated condenser transmitter, resistance-coupled amplifier, and a thermocouple and galvanometer, tests have been made at various frequencies to obtain the sound output from straight conical horns. The horns were made of heavy galvanized sheet iron and include lengths from 30 cm. to 305 cm. and final ope... View full abstract»

    It is shown that, at the limit of regeneration, the relative magnitude of received signal in the plate circuit to that impressed on the grid is inversely proportional to the latter. This inverse signal strength law is explained in terms of the characteristics of the tube. Two methods of determining the effective resistance of a regenerative system are outlined. Practical suggestions are offered fo... View full abstract»

  • On the Calculation of the Inductances and Capacities for a Multi-Range or Other Consecutive Series of Tuned Transmitting or Receiving Circuits, the Total Range and Accuracy Required Being Given

    It is often necessary to use a series of consecutive tunablr circuits to cover a large range of wave lengths or frequencies. The papee describes a method of determining the constants of each circuit when the total wave length range and the accuracy of setting required in each intermediate range are given. Overlap between successive scales is provided for, and a method is indicated by which further... View full abstract»
