    A summary of the historical development of audio frequency induction methods of piloting ships carrying coil receivers along current-carrying cables making the desired course is given. A number of experiments carried out at New London and in New York Harbor are described in detail. The design and mode of use of the cable and the receiving apparatus are fully discussed; and the practical applicatio... View full abstract»

    After considering the general characteristics of a voice-modulated radio frequency current, there is given a systematic classification of the various methods of producing such modulation in transmitters using three-electrode vacuum tubes. The output, efficiency, stability, completeness of modulation, quality, and other characteristics of each method of modulation are studied. The apparatus and cir... View full abstract»
