Book excerpt: Excerpt from Radio Telephony Since the publication of Dr. Erskine-Murray's excellent translation of Ruhmer's "Drahtlose Telephonie," there has appeared no complete exposition in any language, so far as the author is aware, of the important and growing field of radio telephony. The date of publication of Ruhmer's book was 1907, and in the succeeding decade advances have been made which render the methods there described obsolete. Accordingly the author has accepted the considerable task of writing a full description of the radio telephonic methods of the present in the thought that he might thus contribute to progress in that valuable art. Wherever possible, sufficiently complete descriptions of the apparatus employed have been given to enable the person skilled in the art to duplicate the results and to judge their value. In this connection, the ranges of transmission and the output power of the radiophonic stations have been presented. It has been thought, too, that the arrangement of apparatus in the set was of value in that it indicated how the various designers had attacked the problem of making radiophonic apparatus readily usable. It need hardly be stated that a good working knowledge of the methods and principles of modern radio telegraphy is necessary for the full appreciation of the material here set forth, though certain questions. common to both types of communication have been here considered in detail. The author desires to express his deep indebtedness for the valuable assistance in the form of information, illustrations, and diagrams which he has received from the following gentlemen and the organizations with which they are connected: Atlantic Communication Company and Messrs. Boehme, Brockmann and Reuthe; Compagnie Generale de Radiotelegraphie, and Lieutenants Colin and Jeance of the French Navy; Lieutenant W. Ditcham of the British Army; Mr. William Dubilier; Federal Telegraph Company and Mr. Leonard F.Fuller; General Electric Company and Messrs. E.F. W. Alexanderson, Albert W. Hull, and William C.White; Mr. W. Hanscom; Marconi Wireless Telegraph Company of America and Mr. Roy A. Weagant; National Electric Signaling Company and Mr. John L.Hogan, Jr.; Radio Telephone and Telegraph Company and Dr. Lee de Forest; Mr. Bowden Washington; Mr. Eitaro Yokoyama. Through their kindness he has been enabled to present here much important information and previously unpublished material. He also desires to commend highly the painstaking efforts of the editors of The Wireless Press to make this book measure up to the high aims of that organization.
