COUNTRY CROSSED ON SHORT WAVES [Reinatz, Radio Inventor, Is Successful, Bu -VS.I Service SOUTH MANCHESTER, Conn., Jan. 15.—Superiority of short waves, especially in long distance daylight transmission, has been proved again by the experience of John K. Reinartz, the famous radio Inventor, of this city. Rejnartz has succeeded in transmitting signals by day across the continent on a wavelength of 21 meters. F. C. Jones of Berkeley, Cal.; Hewitt Svotewohl of Hartley, Iowa; and William J. Lee of Winter Park, Fla., report to the American Radio Relay League that they heard Reinartx at the time he was making those short-wave tests. For the last two years amateurs have been trying to relay code messages across the continent, in daylight, with little success. The tests were conducted nn longer waves than those used by Reinartz. Now, in _ one direct jump, the country has been bridged by an amateur. Reinartz is the designer of the transmitter that made possible the first two-way amateur communication across the Atlantic. Value of “C” Battery The “C” battery is a precautionary applicance rather than a positive help. Its main purpose is to keep the tubes from draining the "B” battery, thus producing quite a saving. It also reduces set noises. * -V. Vv' Longevity of Dry Cells Because heat hastens the evaporation of the contents of dry cell batteries they should be kept in a cool, dry place, and should always be stood in an upright position, never on their sides.

Short Cuts Things to Know in Building and Operating a Receiver,

LOOP set can be made more sensitive if three turns of tmmm-mJ fairly heavy wire are wound on the frame of the loop inside the loop' proper. These should be from one to three inches from the loop winding. To the ends of this winding attach the aerial and ground leads, thus forming an untuned antenna circuit. * • • * Noisy last stage of audio frequency amplification can be improved if a Daven resisto-coupler is substituted for the faulty transformer. As the terminals of this resisto-coupler are identical with those on the transformer, the change can be made in three minutes. • • • Where a water pipe is not available, you can make a good groumk by attaching ‘ the ground wire twelve or fifteen carbon sticks taken from old dry cells and burying them in the ground. An excellent reamer can be made by filing the converging edges of a screw driver to scissor edges and finishing with an oil stone. Protect soldered joints In the antenna by wrapping them in tinfoil and then a layer of water-proof tape. Pattern makers’ white pine makes excellent radio set baseboard. It is seasoned and rather tough. For Good tone To take the tinny sound out of a metal loud speaker horn spatter it slowly with a mixture of hot paraffin and salt, to which a little vina gar had been added to make It adhesive. When the horn cools apply several coats of flat black paint. Forty Stations % Cuba has forty broadcasting stations. There sre eighteen in Havana alone, more titan in any city in the United States.

Wedding by Radio

'■“■“IHEN the Cincinnati auto \l y show wanted a novelty atJL_J traction, a radio wedding was arranged, which will be broadcast this evening direct from the show through the Crosley station, WLW,. at 9 p. m., central time. Miss Dorothy Ryan and George Baenninger will be the recipient of many presents, Including an automobile. The Rev. Frederick N. McMillan will officiate. WLW broadcasts an 423 meters. Ounce of Noises Crackling and snapping noises may be due to loose joints in the set or to loose joints in the aerial system, or perhaps to near-by power lines. If they stop when the aerial wire is disconnected the source is outside and should be sought in the aerial and ground-- systems.

What Radio Dealers Know About You By VBA Service —IT. LOUIS, Jan. 15.—A C St Louis department partment store owner, dealing in radio, had made the following conclusions regarding radio, radio sets and radio fans: Fans go to department stores more for complete sets than for parts. Many of the sets are bought on charge accounts. Fans want service in installation and proper care of the receiver. Women seldom buy costly sets. If they do, they buy it only after seeing and testing every other set on the market. Men make their choice after seeing only about two or three types. And, most peculiar, the fans know what they want, in receivers.
