RADIO D T G E S T — Illustrated April 5, 192± A. T. & T. IN OPEN FOR FIRST TIME OFFERS TO LICENSE ANY PLANT FOR A FEE Even WHN Would Get a Permit— W. E. Harkness Frankly Names the Prices NEW" YORK. — The American Telephone ^nd Tele npany has hacked down. st. At a recent meeting held S of the Radio Trade .-n to clarity the broadcasting Slt . the A. T. & T. made rank promises and admissions, Ut for the time being any at at establishing a broadcasting W. E. Harkness. vice president of the \ T. & T. company said that the company he represented would license any ~:in« station that applied for one. In replv to a question as to whether he would license Station WHN, he answered, Harkness Gives Figures At the meeting figures on the cost of patent "licenses" were disclosed by Mr. Harkness. "The license fees are from $1 for a recognized educational institution to $2,att stations operated by commercial concerns or others for their own benefit," he said. "The licenses are for the entire life of the patents. "The patents referred to are eighteen controlled by the A. T. & T. and the De Forest companies, both parties in suit now pending against Station WHN for alleged infringement. The statement made by Mr. Harkness, providing it is carried out, assures the American Radio public that any person or organization which has received a license from the Department of Commerce to operate a broadcasting station, can operate the station under the patents of the A. T. & T. on payment of a single fixed sum. A. T. & T. in Open First Time This is the first frank and definite statement from the A. T. & T. saying that any independent owners could obtain a license, or stating the price of such a license. To the question asked by Charles Pope Caldwell, attorney for Station WHN in the suit, as to whether the A. T. & T. would license any station over 500 watts, inasmuch as Station WEAF itself was 0 watts, Mr. Harkness replied, "Our station, WEAF, is not an argument. jre never has been a set built like the set we have. It was done for experimental purposes and it cost us a lot of money. This station operates, moreover, on a special license from the Department of Commerce whose terms can only be met concerns which have a large staff of engineers and complicated equipment. If any of you men, however, want a five-kilowatt set you can have it — if you are willing to pay for it. And it will cost you a pretty penny. It has cost us that." Henry M. Shaw, president of the Radio Trade association, said: "There will be no monopoly in broadcasting, because the public will not stand for it." "KING TELEPHONE" IN MORE TROUBLE Church, Radio Trade Association, Newspapers, Shoulder Arms in Control War NETT YORK. — Aroused by the suit against V.'HX, many new and important interests ha\e joined the fight against the plain attempt of the American Telephone and Telegraph company to control the air. Mr. Henry M. Shaw, president of the Radio Trade association here, has announced his organization as opposed to any such control of broadcasting as the phone company desires. Rev. Charles Francis Potter, representing the Church, is up in arms because advised by the Bell company that if he erected a^station of his own he would be infringing its patents. %tary of Commerce Hoover announces that there shall be no monopoly of the air. Newspapers countrywide are taking up arms against "King Telephone." Previously lined up against the phone company were the City of New York, Station WHN and the North American company. The public's contempt for A. T. & T. tactics had already been aroused by the poorly disguised attempt of WEAF to get contributions to its programs through the creation of the so-called Radio Music fund. Altogether, the American Telephone and Telegraph company could not have better aroused universal condemnation and hatred of its actions if it had deliberately set out to do so. Vacuum Tube in Movies A. — The Pwadio exhibition recently . under auspices of the Technical of Oklahoma featured a motion ire depicting the operation of a. :n tube. PLENTY FROM TOLLS OF 'KING TELEPHONE' NYORK. — Whether or not Station WEAF, "King Telephone," will go to the poorhouse in its attempt to "get while the getting's good," may best be judged by the public themselves who are for the first time privileged to view the income from eek's series of revenue producing programs, a tabulation not released by the A. T. & T. Co., but coldly calculated by forces opposing the attempted monopoly. The paid schedule for March IS to 24, inclusive, yielded an income of $3,400 from ether advertisers as follows: March IS: P. M. S:00— N. Y.

WASHINGTON, D. C. — Recent criticism, especially since the hearings on the White Radio bill, of the granting of Class D licenses by the Secretary of Commerce, has been severe. The explanation has been made by officials of the department that there is nothing unusual in the granting of these licenses. They say the licenses are granted for short periods of time and will be given anyone meeting the requirements. Up to this time licenses under this class have only been granted to Stations KDKA, WGY and WEAF, controlled by large manufacturing interests, members of the Radio Corporation of America. The requirements, however, are such as to make D licenses unavailable except to large Radio interests. Chamber of Commerce at Birmingham Wants Plant BIRMINGHAM, ALA. — The Chamber of Commerce here may be the first similar organization in the United States operating a big Radio station, if their present plans go through. According to Secretary O. L. Bunn the chamber is negotiating with the Alabama Power company for the purchase of WSY. Secretary Bunn explained that the commerce body would have the funds June 1 with which to purchase WSY. "In the event we get the station we will make it one of the largest and finest in the United States," said the secretary. "The advertising benefit to Birmingham and to Alabama would be incalculable."

A number of cases have already been cited as proof conclusive substantiating this claim. The cure is effected by the intensely amplified sound waves which pass along the auditory nerves from the head phones, massaging the nerves and stimulating them to the extent that hearing is restored. One case is reported of a man who two years ago, was totally deaf in his left ear. Now, after constant treatments by Radio, he declares he can hear a whisper across the room. Deaf at Birth; Now Hears Another, a young man twenty-two years of age, deaf and dumb at birth, placed the head phones on his ears for the first time. He wrote on a piece of paper that he was receiving music through his left ear, no sound being audible in his right. Thinking perhaps that the organs of the rigbt ear were in such condition that he would be unable to receive any sound into it, the phone was removed from the right ear and placed over his heart. After doing this the young man was able to distinguish the applause after a concert. Later the phone was replaced to the right ear, and the young man discovered after listening for one hour that he was able to hear with both ears equally well. Looking Ahead "What's Wrong With Your Receiving Set?" — the instructive series by Peter J. M. Clute will tell you all the mysteries of tuned Radio frequency amplifiers next week, and the difficulties often attending the operation of such devices will be explained so that the troubles can be remedied. Four new circuits are to be shown. What Do Radio Inductances Do? — Magnetic fields, coupling, capacity effects in coils, types of coils used in Radio, variometers, variocouplers and load coils, are to be told about next week by P. E. Edleman in his easily understandable style. How do you like "Thirty-Minute A-B-C Lessons for Radio Beginners"? Plain enough? "Straightening Out the Reradiation Problem," a two-part article by Ralph R. Bacher, engineer for one of the finest set manufacturers, will be started next week. He will show you the finished product, made by his company, but will also tell you exactly how to proceed to make your own reradiation preventer, and thus gain the love of your neighbors again. A New Two-Tube Circuit is promised for next issue by H. J. Marx. Its advantages are simplicity of operation and plenty of volume and distance. It's easy to make, too. R. D.-120 for the Hook-Up Hounds has a nice new coil specified that builders of this circuit will have to wind themselves. But it's worth winding for the results.
