ECLIPSE BODY , OE RADIO LEAGUE HEARS SOME MORE

150 Amateurs Turn in Reports on Recent Tests, Bu Times Special HARTFORD, Conn., Feb. 12. The eclipse committee of the American Radio Relay League today completed itß final analysis of the reports turned in by 150 amateur observers relative to the effect of the eclipse on short waves ranging from 40 to 200 meters. The investigation was made in conjunction with the fading tests on broadcast waves arranged by the Scientific American. Fifty of the reports were sufficiently accurate to be used as a basis for study. These showed very plainly that on 75-80 meter band there was a decrease in signal strength beginning or during totality while on the 150200 meter band there was an increase in signal strength during totality. This leads to the possibility according to the committee, that the 150-200 meter band is best for night work while the other band would probably prove more efficient in daylight. . The observers were by no means unanimous in their reports and the conclusions are drawn on the work Hr the majority. Some of the observers on the shorter wave band reported an increase in receiving strength immediately after totality, others placed five minutes after totality as the time of return to normal conditions. The majority on tfie same board reported' considerable fading. One exception was in the case of a Canadian amateur transmitter which three observers declared showed an increase during to* tality. There was a prominent lack of any unusual phenomena, although many observers reported that at the time of totality there was sudden static, frying noises,jnush or crack ling sounds, all of which inay have been due to the increased line voltage or power leaks- Several stated that a tmasmitting station faded out entirely, and that ohe or more faded in on the same wave-length. There were only two reports of ' reception of the 40-meter band, the transmitter heard in both cases being ICKP. All of these observations, ' the committee pointed out, are mitigated by certain offsetting actors, including temperatures and barometric differences.

FOOTBALL-PLAYERS , TRAINED BY AIR Kansas College Plans Radio Stunt, Bti IfEA Berries _ MANHATTAN, Kan., Feb./" 12. Here’s how colleges may prepare a crackerjack football team, right from the start’. Train ’etn by radio. Kansas State Agricultural College Is planning to do this even before the next football season comes around. The plan Is as follows: High school football coaches are receiving a questionnaire from KSAC, requesting particulars as to the type of information which they’ll welcome to aid their teams, and the time most suited for broadcasting. From these. Head Coach C. W. Bachman of KSAC expects to decide on the time and subjects for broadcasting. He’ll then begin a series of football talks from KSAC, the offi-1 cial broadcasting station of the university. This program Is being planned to start far ahead of the regular season, and to' continue on through to the end of the season. In his talks Bachman will try to supplement high school coaching with information on the theory, rules, field tactics and ethics of the game. Along with these talks, there will be charts and printed material which kn *e furnished to the high school aches. From It is expected a better crop of ireshmen for the college teams. Use a porcelain tube when passing the aerial or ground wire through any wall, so that the wire will not touch anything.

The new station a-top the McAlpin Hotel, in New York, call letters WMAC, has acquired one of America’s most famous announcers. He’s Eddie Squires, better known as the "Globe Trotting Announcer.” Eddie got his title from the fact that he has announced at many of the large stations of the country. :* By connecting the wires from the grid of the vacuum tube to the stationary plates of the variable condenser much of the hand capacity will be eliminated.

NEW FIELD OF RADIO ACTIVITY BEINGSTUDIEO Navy Department Centers on High Frequency and Short Waves. Bu Timet Boecial WASHINGTON, Feb. 12—The Navy Department is centering its radio activities in the development of high frequencies or short waves in the belief that they will open up an entirely new field. Capt. Ridley McLean, director of naval communication, Is planning elaborate experiments In this connection during the next six months. “The possible development of reliable long-distance radio communication in the naval service on high frequencies with low power,” says Captain McLean, “has recently been brought forcibly to the .attention of the department, principally because of the successful long-distance reception at Balboa and San Diego of regular traffic dispatches by the experimental high frequency transmitter at the Bellevue laboratory. “Some idea of the possibilities of this method may be had If consideration be given to the fact that the only antenna used at Bellevue for this long-range work is an ordinary galvanized Iron pipe, thirty-five feet

long and about two and one-half inches in diameter on the roof of the laboratory, with no wires whatever. .Balboa used a simple homemade receiver. “Steps are being taken for experimental recepfiofl~ln the Hawaiian Islands and the Philippines. It is expected that extensive experimental

work on high frequencies will be conducted during the coming fleet maneuvers. Despite the above results, high frequency work must be regarded as still in the experimental stage. It is a field offering wide possibilities, but much research is necessary before it can be definitely relied upon for long-distance traffic.”
