Radio Broadcast (May-Oct 1922)

RADIO BROADCAST 39 the distances over which receiving outfits will function satisfactorily. This method employs what is known as radio-frequency amplification. The beginner should not attempt the use of this method unless he purchases radiofrequency amplifying units complete, because some difficulty may be experienced in assembling the various parts, which go to make an amplifier of this kind. Where we hear of signals being received over very long distances by stations employing a loop aerial, it is safe to conclude that radiofrequency amplification is being used. With a loop three feet square, wound with five or six turns of lamp cord functioning with suitable radio-frequency amplifiers, very great distances may be covered. The loop form of reception is very valuable for the reduction of static and interference because it is only influenced by signals from points directly in hne with the winding of the loop. That is, in order to receive from any station the loop must be pointed toward that station and interference having its origin in any other direction does not occur. Therefore, the only interference likely to occur is caused by two or more stations operating on the same electrical wave length and located in the same direction from the receiving station. With two stages of radio-frequency, signals have about the same intensity as exists when the average amateur outdoor antenna is used in connection with a standard regenerator circuit employing one vacuum tube. RADIO PERSONALITIES PAUL GODLEY By a. henry IT IS doubtful whether any one human being in radio circles holds the interest of Americans more completely than Paul Godley. Much of this interest is the direct result of the transatlantic amateur transmitting tests completed a short time ago, in which Mr. Godley played the leading role, but he has also taken part in other remarkable radio activities. Before considering these recent events it is interesting to ponder for a moment or two upon the work this man has done for radio in the past. Paul Forman Godley was born September 25, 1889, at Garden City, Kansas. His interest in radio began about the time he entered Defiance College in Ohio. His studies there lasted for five years. During his summer vacations, Mr. Godley devoted himself to telegraph work with commercial companies and railroads in various capacities, from operator to train dispatcher. Being interested in communication, it was quite natural for him to become enthusiastic about radio and he studied all the available literature on radio communication published at that time. In 1908 a commercial wireless station was built in Chicago, to which Mr, Godley was assigned by the operating company. Once in a position actually to handle commercial radio equipment, Mr. Godley made every effort to become proficient in its installation and maintenance, as well as its actual operation. The United Wireless Telegraph Company opened a commercial station at Grand Rapids, Michigan, in the summer of 1909 and Mr. Godley was put in charge. Later in the same year, an agreement was made with Dodges Institute of Telegraphy, Valparaiso, Indiana, to inaugurate a course in wireless telegraphy over which Mr. Godley had jurisdiction. In 191 1, Mr. Godley was placed in charge of a course in wireless telegraphy at the Collegiate Institute, Port Arthur, Texas, and in 19 12 he took up the duties of Wire Chief for the Postal Telegraph Company at their main New York office. The year 1913 found Mr. Godley on the "Amazon-to-the-Andes" radio service for the Brazilian Government, during which time his experiences were as varied as they were instructive. In 1914 Mr. Godley returned to the United States, and began a study of research at his home, Leonia, New Jersey, where he devel
