Nilson Arthur R., Hornung Julius L. Practical Radio Communication: Principles - Systems - Equipment - Operation

2nd edition. — New York; London: McGraw-Hill, Inc., 1943. — 980 p.Rapid and extensive advances in the science of radio communication make this second edition necessary. Approximately two-thirds of the text is new. A noteworthy improvement has been made in chapter groupings; basic radio principles are now concentrated in the first eight chapters. Aviation radio, broadcasting, and marine radio follow in the order given. This arrangement will make the book easy for the student to use, for he will concentrate first on those chapters in which he is immediately interested, saving the remainder of the book for postgraduate study. The adaptability of the book to this latter purpose is attested to by its large distribution to employed radio operators who continue studying for self-improvement.
