Produktbeschreibung
Excerpt from Robison´s Manual of Radio Telegraphy and Telephony: For the Use of Naval Electricians This manual, first published in January, 1907, was revised in 1909 by L. W. Austin, Ph. D. The present (2d) revision contains the results of some of Dr. Austins later researches as well as more detailed instructions relative to installation, care and operation, also additional appendices, containing extracts from Service Regulations adopted at the International Wireless Telegraph Convention in Berlin, October, 1906, and the U.S. Statute of 1910, relative to wireless telegraph apparatus on merchant vessels. The author is also indebted to Mr. J.Martin, of the Navy Yard, New York; Mr. Geo. P. Hanscom, of the Navy Yard, Mare Island; Mr. Geo. H.Clark and others for figures, illustrations and suggestions. July, 1911. Preface To Third Revision Advantage has been taken of the necessity for a new edition to regroup subjects; to add articles and figures relating chiefly to the use of imdamped oscillations; to note the results of some of Dr. Austins recent researches; to alter appendices to include the London Convention of 1912 and the U.S. Statute of 1912, and, through the kindness of LieutenantS. C.Hooper, Tj. S.N., to extend the chapter on care and operation. August, 1913. A new edition being necessary, minor corrections and additions to the third revision have been made. December, 19 Preface To Fourth Revision The copies of previous editions having become exhausted, certain changes have become necessary to bring the Manual up-to-date. Owing to the many responsibilities placed upon Captain Eobison, due to the war, the revision has been made by Captain Todd and Lieutenant Commander Hooper, who offer the Fourth Edition as Robison´s Manual of Radio Telegraphy and Telephony. Credit is due to Lieutenant H.P. LeClair, U. S. Navy, in charge of the Radio Division, Bureau of Steam Engineering, and Mr. Charles J. Pannill, Expert Radio Aide, Office of Director Naval Communications, for many valuable suggestions and their work in connection with the revision of this Manual. January, 1918.
