Radio broadcast .. (1922-30)

512 Radio Broadcast A PRODUCT OF THE BUCKEYE STATE Willis Danback, of Tiffin, Ohio, is the designer of this receiver. It has 2 stages of A. F. amplification, but he has done some good work with one tube Vernon Trigger, of Carsonville, Michigan, relates making a score of 25,500 miles in six and a half hours. "This little long-distance hop," he tells us, "was accomplished with the aid of a home-constructed standard regenerative receiver. By the way, it appears that the old 'stand-by' seems to be losing out to the new and numerous single-circuit outfits. The trouble with three circuits, using two variometers and a vario-coupler, is the difficulty of tuning them. Hauling in 2ooo-mile stations with another about 150 miles away ripping along with a beautiful carrier-wave is the result of a fifty-fifty mixture of perseverance and perspiration." J. E. Bradley, of Justin, Texas, reports practically the same mileage, 25,010, in one evening. That particular evening, he and Mrs. Bradley started listening-in at 5:45 p. M. and finally called it a day, or rather a night at 3:18 A. M. Has a sort of familiar sound, hasn't it? We wonder if there is one among our readers who hasn't sat down at his set with a firm resolve to spend fifteen or twenty minutes at it, and then put off the quitting time again and again until the bell in the clock-tower from somewhere outside boomed in the news that it was i G. M. ! Charles H. Hewitt, of Southern Pines, North Carolina relates hearing stations all over the country on a single-circuit regenerator, to the tune of 109,025 miles. Much of his DX results he obtained after 2 A. M. He uses a vernier condenser in parallel with the usual variable in the ground circuit. This is a good point, and ought to improve the tuning of any set. Ralph S. Ramsay, of 625 North Frances St., Madison, Wisconsin, has been using a dry-cell tube with a home-made set, and gets Los Angeles (1500 miles), Calgary (1200 miles), and San Antonio (1000 miles) consistently. He lists only 21 of the stations he has heard These aggregate 15,975 miles. D. C. McCoy, of Charleston, West Virginia, who has been a radio bug for some thirteen years says that he recalls with a smile the old days when he " used to sit up half the night to get a few signals from some station 50 to 100 miles away." He made his present set out of various improvised, bought, and salvaged parts, making all connections as short as possible between the various units and soldering everything — even the connections on the prongs of the tube, instead of using a tube socket. The set is of the single-circuit regenerative variety. Mr. McCoy's longest jump is 2150 miles, and his aggregate is 28,205.
