    The development of short wave communication by the Radio Corporation of America is outlined. A summary of short wave installations, with call letters, wave-lengths and services to which each installation is assigned, is submitted. Traffic charts showing the diurnal and seasonal characteristic of various wavelengths over typical circuits are shown. An outline of the technical problems inherent to t... View full abstract»

    Propagation data over the frequency range of 3,000 to 30,000 kilocycles is submitted. A co-relation is shown between wave frequency and angle of projection of the wave front. The effect of ionization on the angle of projection is indicated. Some calculations are given of probable values of attenuation constant. The importance of frequency stabilization is discussed. Three typical circuits for util... View full abstract»

    The maxima and minima of a function of a real variable are found by equating to zero the derivative of the function. In the case of a function of a complex variable however the derivative is a vector quantity, so that conditions may be imposed upon its direction as well as upon its magnitude. These various conditions lead to maxima and minima of the various aspects of the function. Rules are devel... View full abstract»

    The necessary conditions for the maximum secondary current are -and M2 2-Z R -1 Z2 which may be established with only two variables making it unnecessary to tune the primary. The secondary current is then 2 22 -- VRRR2 This leads to a tube constant y as a measure of its V Rp efficiency in a R. F. amplifier, also a coil constant LR for the secondary coil efficiency. When the secondary only is tuned... View full abstract»
