Excerpt from A Treatise Upon Wireless Telegraphy and Telephony While serving as Inspector for the United Wireless Telegraph Company, the attention of the author was frequently called to the inability of operators to efficiently use the apparatus installed for Radio communication over which they had supervision. This inability could almost invariably be traced to either a misapplication of the principles governing the action of certain instruments of the equipment, or a deficiency of knowledge concerning these principles. Many operators, having had no previous training, were unable to master the technical explanations given by some of the prominent authors of treatises upon Wireless Telegraphy on account of the mathematical reasoning employed by them. While it is impossible to go deeply into the study of Wireless Telegraphy without the aid of higher mathematics, an attempt will be made in this book to explain in as unmathematical terms as possible a few of the fundamental principles and to illustrate their application to the solution of practical problems which arise daily in the routine of wireless operating. Fortunate indeed is the student of wireless telegraphy who has had the opportunity of studying "The Principles of Electric Wave Telegraphy and Telephony", by J. A. Fleming, and the "Principles of Wireless Telegraphy", by Geo. W. Pierce, and it is on account of the clearness of the explanations and the reliability of information given in the above mentioned books that they will be quoted in the following pages. The author wishes to mention his obligation to the Wireless News and Publishing Co., Sampson Publishing Co., Clapp-Eastham Co. and the Electro Importing Co. for permission to use certain illustrations furnished by them; to the Standard Wireless Equipment Co. for the loan of equipment tested; to Mr. J. M. Baskerville for the loan of a number of photographs of equipment which have materially assisted in explanations; and finally to Mr. G. M. Dodge, whose friendly assistance has made the publication of this book possible. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
