i D! THE SUNDAY - STAR, WASHINGTON, D. C, JULY 29, 1923—PART 1 In connection with its efforts to %eep apace with all safety and res- ‘'@ue developments, the bureau of imiftes of the Department of the In- ‘terior, 1s planning to continue its in- westigations with radio communica- tion underground. The development ©f radio has been rapid and official ©of 'the bureau feel that any applic: tion to mine rescue work must not 108 neglected. » J. J. Jakowsky, mechanical eng neer, has been designated to unde take certain experiments in radlo communication at the bureau's ex- perimental coal mine at Bruceton, Pa. Mr. Jakowsky was attached to the Signal Corps during the war, where he had considerable experience with radlo work. The co-operation of the radio supervisor at Pittsburgh has been promised by the Department of Commeroe in the new radlo ex- periments, Some months ago preliminary radio experiments in sending and receiving underground at the Bruceton mine were conducted with partial success. In reporting on the matter the bureau of mines stated that the experiments | consisted in receiving signals from without the mine by means of a re- ceiver located inside the mine, and in sending and receiving messages underground through the strata. It was found that with a receiving in- strument set at a point of 100 feet! underground, signals from KDKA station. East Pittsburgh, Pa. could be heard distinctly at a distance of about eighteen miles from the experi- mental mine. In sending waves un- aerground, a Westinghouse twenty-watt B. T. model T. F. transmitter was | used in such & manner as to send | out continuous waves of 200 to 300} meters length. On account of the ylimited time no attempt was made to | modify the apparatus in such a man- ner as to produce waves of Jength. Tt was found that signals | could be heard distinctly through | fifty feet of coal strata. but that the | audibility fell oft rapldly as this dis- nce was increased. In all experi- ments a vertical antennae was found 1o give - the better results. The liorizontal antennac gave practicaily no reception. A loop of a single turn { was used with fair results. All these experiments were tried with a wave length of 200 300 meters, except the reception from KDKA, which was | 360 meters. Tn conclusion the report stated: “The present preliminary experi- | ments, while unsuccessful in Indicat- ing any practical method of using wireless waves for underground com- munications, nevertheless indicate clearly that electromagnetic waves may be made to travel through solid strata. The “absorption” or loss of | intensity with distance is very great for the short wave lengths used in these periments. Longer wave lengths are known to suffer less ab- sorption_and may possibly be found practically effective ‘under: certain conditions.” greater To Kreet New Statlon. Recognlzing the value of radio as a means of disseminating valumble in- srmation -t the general public. A Stone. the mnovelist, lecturer and philantrophist of Milton-on-the Tudson, New Yor (and also founder of the A tone Foundation, an or ganization that devote itself to- ward the realization of worthy objects). is muking preparations to eatablish a powerful radio broadcast ing station upon his estate at Milton this fall. The station. which will probably be fifteen kilowats and will | broadcast on a wave length agrecable | to the proper authorities, will be used | for the purpose of broadcasting lec- | tures on important topics. which will | Include science and literature. For this piurpose Mr. Sto will enlist the services of nationally known? lecturers, while he himself will de- vote two hours each week to broad- | casting talks on current literary | topics I Stome's estate on the Hudson ts an Ideal place for the estublishe /ing of a bropdcasting plant. Over- looking the rivér_the highest point on his estate is 700 feet above sea level, which is quite an advantage in_broadcasting. Members of the Authors’ League of | America, of which Mr. Stone is a| member, are wdtching the results of | the experiment with a great deal of interest. 3 How to Read Time Signals. From many inquiries received it is evident that the average listener does not understand how to make use of the time signals as transmitted | each day from the Arlington station | NAA and retransmitted from many other stations. By observing the following instruc- ions listeners will be able to make | use of this service The time signal is transmitted in a series of dots. each dot representing & second. Beginning usually at three, minutes before 12 o'cloc eastern | time., twenty-nine dots are trans- mitted, representing the first twent nine seconds of that particular min- | ute. and the thirtieth second is| omitted; twenty-five dots are then) transmitted, which represent the first twenty-five seconds of the last half of that particular minute, and the last five seconds of the half minute omitted. The next minute is transmitted in exactly the same ‘way—that is, twenty-nine and skip one, twenty- five and-skip five. On the last min- ute of the hour the first half minute is sent the same, that is, twenty-nine and skip one, and the last half min- ute is sent out twenty dots, and the ;last ten are omitted. although in some instances twenty-one or twenty- two dots may be heard, with eight or nine omitted, as the case may be. At the end of this eight or nine second interval you will hear a long dash, which represents the exact-time. By | watching the difference above noted vou can tell when your are listening fo the last minute of the hour rather than any of the others. The code which follows the final dash is simply a station call and & signal to “stand by" for the weather and market reports on voice Tall Corn Radio Contest. One of the most, unique contests of the vear is that being sponsored by statfon WOC at Davenport, Towa. Thid station is often heard acclaiming proudly that it is located in lowa. “the state where the tall corn grows.” To exemplify this phrase and to jus- ify the statement in the eyes of §1any who may be skeptical among its many visitors from other states, & tall glass case has been installed as a part of the station's unique furnish- ings, and in this case is to be dis- played twenty stalks of lowa's tallest corn. To stimulate an interest in inten- sive cultlvation the Palmer School of Chiropractic has offered $50 in prizes to the Towa boys and girls who pro- | duce the twenty stalks with the greatest average height. At the end of the growing season contestants ‘are to submit the average height of their twenty tallest stalks, measured from the ground line to the "R of the tassel. When the winners ha been picked they will be notified to} hip the corn (crated with ears a fllugad) to the Davenport lutlon,’ where the measurements will be checked and the prizes awarded. Duck Dinner Gives Idea. Capt. Donald MacMillan first got his idea of taking radio on his trip north- ward to the pole at a “duck dinner” xiven him in Chicago last spring. At the dinner Capf. MacMillan met E. F. McDonald, a radio engineer, who ex- plained the value of a receiving set s & means of getting news, concert: and other matt from the states during the long stretolfes of arctic solitude, which is the real hardship of the north, according to the captain. At first the explorer explained that Jimited space Dreveniéd the -installa tion of u set, but_later he agreed that it would be fine for his men. As soon as he was “sold” en the recelving end, Mr. McDonald. and a friend began to expound the greater value of a trans- mitting set, incidentally mentioning the possible distribution of informa- ion and stories to the world at home. FRe Captain Anally decided he wanted a complete radio outfit, and some de- clare that the equipment will make him the most popular arctic explorer, lof WNI whether he or not. Shortly after the dinner representa- tives of Mr. McDonald’s firm, the Zenith Company, visited the Bowdoin, and outfitted her with sending and receiving equi ent of the latest de. sign. Through the co-operation of the American Relay League and the North American Newspaper Alliance the world 1s now hearing of Mac- Millan's progress, while he and his crew recoive the dally broadcasts fust as we all receive them here at ome. Amateur Cenvention in Chicago. All “Hamdom" will meet in Chicago! The largest gathering of radlo amateurs in history is scheduled for the windy city September 12 to 151 when the second national American Radio Relay League convention, will be held here under the auspices of the Chicago Radlo Trafic Assoclation, with headquarters at 959 Rookery. This was announced here today fol- lowing receipt of information that Chicago had been =relected as the scene of the convention by the Amer- ican Radio Relay League board of di l l’:}l!llfl’l at a meeting in New York city. DX fans all over the country and Canada, from New York to the Golden Gate and Ontarlo to the gulf, many of whom communicate with each other nightly over thousands of miles through the American Radio Relay League relay system and who know each other best by their call letters, will here meet face to face for a discussion of their speclal prob- lems. There has been but one other such convention, held in Chicago in 1921, and the tremendous strides in ama- teur radio since that time and with it the growth of the amateurs’ rep- resentative body, the American Radlo Relay League. will make the coming event one of great moment to all amateurs and to to the radio public in general, Since that first meeting amateurs using low power have sent their sig- hula across the Atlantic and Pacifie oceans, thelr transmitters have worked stations in Australia and New | Zealand and their calls have been neard in South Americw and Africa. One of thelr number is now radio operator on Capt. Donald B. MacMil; jlan’s schooner bound for exploration of the arctic. With thelr transmitting stations reducing the size of the giobe month by month amateur interest is running high, and the coming convention will carry this spirit of progress in re- view. Code for North Pole News. Receipt of news by radlo from the north pole right in the summer heat of their own homes, is the privilege which is being accorded thousands of amateurs, who know the code, through the special arrangement be- tween the American Radio Relay League and the MacMillan arctic ex- pedition, which is even now passing icebergs on the way to that dreary northland where the Eskimo. the polar bear and the walrus live in a temperature of 35 degrees below zero. Few radio fans realize that the transmission of code travels much greater distances than is when similar waves are moduluted by ound vibrations, which explains why | the radio telegraph code, rather thun phone, is employed by the MacMillun exploration party to establish com- munication with civilized countries in the northern hemisphere, thus bring- ing into direct contact individuals who are living in two extremes of temperature. The value of which has been long emphasized as one of the greatest pleasures of radio, and an incentive to the fan who has hankering for distance or DX records. is doubly appreciated by amateurs who listen for wireless | north pole, as MacMillan's station call | WXP is Known, and not a few are | brushing up in their skill to recefve telegraph messages at high speed. Many listeners may be interested to know that Donaid I Mix. the radio operator on MacMillan's xchooner, the- Bowdoin, who Is go- ing north in the employ of the league, was once a fan who sat up until early morning to hear distant stations., He learned the code and when the chance came, he was chosen by the American Radlo Relay League as the “ham” who would thrill the world with north pole dispatches.
