RADIO DIGEST — Illustrated May 10, COURT GIVES RIGHT TO USE MUSIC FREE CINCINNATI RULING IS BROADCAST VICTORY Holds Rendition of Song by Air Wave Is Not Public Performance for Profit CINCINNATI, O. — A victory for broadug stations using musical numbers on which a copyright has been granted was won in the United States District court here when Judge Smith Hickenlooper dismissed a petition tiled to halt the broadtag of such numbers without paying the holder of the coypright. The suit was filed by Jerome H. Remick £ Co., New York music publishers, against the Crosley Radio Corporation of this city, manufacturer of receiving sets. Judge Hickenlooper said he does not think the rendition of a song in the seclusion of a broadcasting studio is a public performance withii the intendment of Congress in enacting the present copyright law. Broadcast Intelligence and Music Judge Hickenlooper said: •'These Radio stations are operated for the transmission through space of intelligence and music. Such a station is undoubtedly maintained to stimulate interest on the part of the public, to advertise receiving sets and instruments of defendants' manufacture, and to permit the persons having receiving sets to receive a reproduction of the sounds broadcast. "It must also be kept in mind that broadcasting stations are maintained throughout the United States by those who have no direct connection with the manufacture or sale of Radio equipment, solely for the advertising value of such broadcasting stations. A notable example of this is the station maintained bv the United States Playing Card company here; other examples are those stations maintained by newspapers at various points. Not Public Performance for Profit "In order to constitute a public performance in the sense in which we think Congress intended the words 'perform publicly for profit,' it is absolutely essential that there be an assemblage of persons, an audience so congregated for the purpose of ORGAN DUET PROVES STELLAR ATTRACTION The more important half of the world's greatest organ team, Mr. and Mrs. Jesse Crawford, is shown at her console of the mighty Chicago theater duet pipe organ, said to have taken more than a year to build. The team may be heard by Radiophans tuning in on WM AQ, Chicago, _ between the hours of nine and ten, Eastern time, on Saturday nights. Mr. and Mrs. Crawford have consoles at opposite ends of a large orchestra pit but wear telephone sets to assure synchronization. Int. Photo WAVE LENGTH LIMITATIONS Are now conquered and it matters not whether you receive at 50 meters or 50,000 meters. All you need is the proper inductance and that means using THE LOW LOSS GENERAL INSTRUMENT CORPORATION GROUNDED ROTOR CONDENSER hearing which transpires at the place of amusement. "We simply feel that the rendition of a copyrighted piece of music in the studio of a broadcasting station, where the public are not admitted and cannot come, but where the music is converted into sound waves that are received in the homes of owners of receiving sets, is no more a public performance than the perforated music roll which is a reproduction of copyrighted music." According to professor H. S. Taylor, of the Department of Chemical Engineering at Princeton University, transmission of power without wires to aircraft, railroad trains, and ships hundreds of miles from the power plant is a possible development in the Radio field. LOW LOSS GENERAL INSTRUMENT GROUNDED ROTOR CONDENSERS Have Practically No Dielectric Losses and Hence You Get 37% MORE DISTANCE AND VOLUME THAN WITH THE AVERAGE VARIABLE CONDENSER CHARLES SREBROFF, operator and owner of station 2 BHY writes, "You can use my name in your advertisements so that other amateurs may profit by my experience with your LOW LOSS GROUNDED ROTOR COXDENSER.
