    The general characteristics of the ideal output tube for broadcast receivers are discussed briefly with respect to specific electrical and acoustical requirements. Considerations of practical power-tube design indicate that the tube most nearly approaching the ideal characteristics is one having an accelerating grid (screen) and a control grid which does not require power. The limitations of conve... View full abstract»

    An historical introduction reviews the initial long-wave telegraph circuit with the East Indies in 1923, the first short-wave telegraph circuit in 1925, and the inauguration of short-wave telephony in 1928, this being accomplished by means of the usual double-side-band and carrier system. The principal limitations attending this method of operation are discussed; viz., the phenomena of fading, sus... View full abstract»

    This paper deals with the application of feedback to amplifiers for the sole purpose of obtaining a frequency discrimination in the gain-frequency characteristic of the amplifier. The theory of the feed-back amplifier is given and the general form of the vector envelope μβ representing the over-all propagation factor of the amplifier and feed-back circuit is described for a feed-back amp...

    This paper describes the use of the inverse feed-back principle to obtain sharply selective circuits. Important advantages of such circuits are (1) inductances are not necessary, (2) "tuning" may be changed by merely varying resistances, (3) ready adaptability for use at very low frequencies, (4) "tuning" may be varied over wide ranges of frequency while maintaining a selectivity curve which is a ...

    Data on the ordinary-wave critical frequencies and virtual heights of the ionospheric layers are presented for the period indicated in the title. The monthly average values of the maximum usable frequencies for undisturbed days, for radio transmission by way of the regular layers is also provided. View full abstract»
