    The paper gives a resumé of the measurements of 1924. Observations were taken twice a day on the folowing stations: Lafayette (Bordeaulx), Ste. Assise (Paris), Nauen (Berlin), Bolinas (California), Monte Grande (Argentina), and Cayey (Porto Rico). In addition, measurements were made in August and September at San Diego, California, on signals from Cavite, P. I., and Malabar, Java, respectivel... View full abstract»

    This paper describes in detail the equipment and circuit used in the production of the single sideband for trans-Atlantic radio telephony in the experiments at Rocky Point. The set consists of two oscillators, two sets of modulators, two filters, and a three-stage amplifier. The oscillators and modulators operate at power levels similar to those in high-frequency communication on land wires. The t... View full abstract»

    The paper describes the development of a 150-kilowatt (output) radio frequency amplifier installation built for trans-atlantic telephone tests. The characteristics of the single-sideband eliminated-carrier method of transmission are discussed with particular reference to its bearing upon the design of the power apparatus. A classification of amplifiers is proposed in which there are three types di... View full abstract»

    This paper considers Dellinger's treatment of the radiation from antenna systems, and applies correction factors thereto for the field strength near to the antenna. The term "equivalent height" is suggested and is differentiated from effective height. The expressions are then applied to the case of a tuned receiving antenna to determine the distortion produced in the field of a distant transmitter... View full abstract»
