    This paper describes the construction of a short-wave single side-band reduced-carrier system of radio transmission. It also reports the results of comparisons made between this system and an ordinary short-wave double side-band system between England and the United States. It was found that the single side-band system gave an equivalent improvement in radiated power over the double side-band syst... View full abstract»

    The method and equipment used in monitoring the standard frequency emissions are described in this paper. The emissions are continuously recorded in terms of the primary standard of frequency maintained by the Bureau of Standards. By means of selector circuits and frequency multipliers the received signal is heterodyned with the appropriate harmonic of the primary standard. The beat frequency is t... View full abstract»

    Results of ionosphere measurements utilizing transmissions at vertical incidence and made weekly over a period of eighteen months are discussed. Typical graphs of diurnal variations of the E-layer critical frequency and its relation to the ionizing force of the sun are shown for three seasons. Similar graphs for the F2layer are included as well as a seasonal curve of midday, and maximum... View full abstract»

    The operation of class C amplifiers under carrier and modulated conditions is analyzed with the aid of constant-current charts. With these charts one can precalculate all operating factors such as output, efficiency, and grid driving power. The analysis discloses certain fundamental differences in the behavior of modulated amplifiers connected with self-bias and fixed, or generator bias operation.... View full abstract»

    It is well known that the terminating impedance plays an important rôle in the action of a filter. Using a terminating impedance which approximates the negative of the usual iterative impedance is shown to result in transmission not specified by ordinary filter theory in addition to that in the customary pass bands. The effect is essentially one of resonance which can be produced in a suppres... View full abstract»

    A selective bridge, consisting of three resistive arms and a fourth arm comprising a sinusoidal sixty-cycle voltage, has been devised and applied to the study of radio-frequency power amplifiers. In Part I the measuring circuits are described, and in Part II some typical data on a type 10 tube are presented. The observed linearity of contours of constant plate loss on a diagram plotted to the co&#... View full abstract»

    The complex value of an impedance may be measured at radio frequencies by measuring voltage ratios on a transmission line terminated in the unknown impedance. The line may often be replaced advantageously by an equivalent network. Several new methods of carrying out the measurement have been developed and a study of the factors affecting the accuracy and the technique of manipulation has been made... View full abstract»
