    The Navy Department's policy of pursuing the development of vacuum tube transmitters and the reasons therefor are discussed. There are then outlined the performance requirements for apparatus of this type for Naval use and the considerations involved in its standardization. There are made some preliminary statements regarding standard equipment, including the discussion of ratings and circuits use... View full abstract»

    The operation of the Poulsen Arc with only one voltage peak per period is shown to be desirable in that it permits the use of weaker magnetic fields across the arc and gives a nearly sinusoidal radio frequency current. The obtaining of one-peak operation by a suitably shaped and situated cathode cooling shoe is described and explained. View full abstract»
