RADIO DIGEST mnmi May 12, 1923 r HAVE COURTS RIGftT TO REGULATE AIR? WILLIAMS-BERGMAN CASE TO DECIDE ISSUE Youthful "Sparks" Sued by Banker Radi ophan for Alleged "Gumming Up of Atmosphere" By E. E. Pearson BLOOMINGTON, ILL. — Have the courts jurisdiction over the air? Can legal mandate control the boundless ether which extends from planet to planet and which has puzzled the scientists since the times of Aristotle? Will an injunction extend through the empyrean? These and other problems may be solved when the case is called in a few days in the Livingston county circuit court, the first injunction suit ever instituted to restrain a broadcaster by Radio. The lawyers for the defense and prosecution have been busy preparing for the hearing, set for the April term of court. The eyes of the Radio world will be centered upon this unique issue. Men of national prominence from many sections of the country will assemble, including Herbert C. Hoover, secretary of commerce; Mitchell Lewis, machine gun manufacturer of New York; Hiram P. Maxim, president of the American Radio Relay League; K. B. "Warner, secretary of the league, and other notables. Banker vs. Youthful Sparks When Cutter in his "Song of the Lightning" wrote, "Away, away, through the sightless air, stretch forth your iron thread," he had little idea to what marvels the study of electricity would lead. Yet his words were strangely prophetic when he predicted: "The journey ye make in a hundred years, I'll clear at a single bound." Principals in this initial case, involving the right to use the air, are Bdward JSeWilliams, president of the State Bank of Dwight, and W. Wylie Bergman, a youth of 18. McWilliams applied for and was granted a temporary injunction which restrained Bergman, an amateur Radio operator of the same city, from operating his broadcasting station, because it interfered with the receiving of Radio messages in the McWilliams mansion. Tucked in one corner of the living room of the Bergman cottage is the Radio apparatus which has created such a turmoil. The little cubby hole that houses his instruments is packed and jammed with coils, gaps and other Radio apparatus. On the walls are tacked messages received at various times. He proudly exhibits his commission as chief of the northern Illinois district. High in the air, a distance of 150 feet, are his lofty aerials. Day and night they receive and send the messages from and to other amateur stations from one end of the country to the other.

SLAP 132 NASSAU ST., NEW YORK CITY Now It's Spring — Moving and House Cleaning Are Over — and the weather is so nice that it would be a fine time to get up on the roof and repair or rebuild that antenna for the coming summer months. And in accordance with this suggestion, Thomas W. Benson, in his beginners* series next issue, 'will devote Chapter III to "Pointers About Aerials and Grounds." Let's fix up the stormbeaten old copper wires for many merry moments during the cool of the summer evenings. Mr. Benson's Loud Speaker Construction Article, by the way, stirred up so much interest and brought his so many letters that he has promised to furnish soon an article for the Digest which will be a consensus of the data and information requested by the zealous homemade loud speaker constructors. FleweUing Next Issue will tell Radiophans more about the making at home of a first-class one condenser flivver super. He's really anxious to help the many misguided Flewellingphans who can't get theirs to work properly, so read his detailed series now appearing in the Digest. May 15 Is the Date for Many Wave Length Changes — That's why you should have the Digest's weekly three-part Broadcasting Station Directory (Page 8) to help you with the latest information on station wave lengths, schedules, calls, owners, time bands, etc. "An Evening at Home with the Listener In" is a feature that helps, too. Next issue this will contain a complete revision of wave length data. H. J. Marx and His Reflex De Luxe, will be with us again May 19. He will tell you how the wiring should be done. He also promises — not next issue but soon — some honest-to-goodness data on the Hazeltine Neutrodyne receiving circuits. And another article he is planning is one which will tell how to build loading coils for Reinartz receivers, so that their wave length range will be increased.
