Show UTAH TO HAVE BIG WiHElESS STATION ! A wm-less aerial fi.r Utah, which will be about six timfs as bi.s;h as ar:y o. her station in the worl'i, is now be- j in4 cfmstrueted at "Ihlsile under the direction of A. H. Ernst, i peration for the Denver &. Rio Gr. title. A wireless receiving set recently was received from the Electro Importing corripir.y oi New York, which Mr. Ernst sajs is as fine a set as ever has been made. When the aerial is completed it is thought that messages s n; inm the iisw government station at Arlin.tin, Va., wid be heard clearly at 1 hustle. . Trie aerial at Thistle will be about 1500 feet high, which is about 700 feet higher than the government station at Arlington. In addition to that, Thistle has an elev-ation of 5000 feet, wh le Arlington is only a few hund.ed feet above sea level. As, since the advent of wireless telegraphy, it has always been considered that the higher one can get for an aerial the better ar.d longer wilt be the sending and receiving receiv-ing range, amatejr and professional operators throughout the world will watc l with keen interest for the results re-sults to be attained in Utah. As .here will not, for the present, be any use for a sending apparatus set and as the nearest stations are too far away to warrant the installation of the txpensive set, none will be installed. It has been suggested that t ie new high-power wireless station at Arlington Arling-ton is but the first step in a system to extend around the world, with stations at Colon, Hawaii, Guam, Pearl Harbor, and the Pnilippines. Such a 'ation at j tie command" of the United States navy would imt every ship in the navy j and also our inrular possessions in con- j ' stant communication with Washington, i The- system complete would cost in the , ! neighborhood of a million dollars. j j The Arlington station lias cost $'J00,- : 0)0, and it is the world's great st wire-! wire-! less plant. It is on the summit of a , hill about a mile south of Ihe drill field : of Fort Meyer. Three huge steel towers there on the brow of a hill over- ! j looking the Potomac and dwarfing the. Washirgton monument hold the aerials wh eh rling off messages to the other. 1 In the construction of those towers, ski I le I iron workers, who have braved deith on a skyscraper declined to wjrk , at such di.zy heights. One tower is 800 feet and each of the others is C5J feet in height. Unique in its construction con-struction :s th.! rajio operator's room, j It is something like a huge refrigera-i refrigera-i tor, is absolutely sound proof and, I when its door is closed, the radio opera - tor on duty carnot hear anv sound 'from without or can he be bothered I by vibrations. The only entrance into ! the room is through a double refrigera.-; refrigera.-; tor door. The room has no windows, is artificially lighted and ventilated, and the air used is said to be sound proof, having passed through a series ! of air ducts in which "baffle plates" ' are strung. Radio communications limited now a license being required of all wireless operators and all apparatus which works across state lines or can communicate commu-nicate with ships at sea, must be li-. li-. censed. This act is one of the bjpio-i bjpio-i ducts of the Berlin international treaty, which was ratified in April by the United States senate. The steps toward to-ward obtaining a license include an ex-i ex-i an.ination in the customs house or the n ivy yard, and the examination is a ; rigid one. Everybody must also, re-' re-' gardless of class or grade, swear to : keep secret any messages he may pluck 1 out of the air, unless ordered to divulge i those messages by a court or competent compe-tent authority. I Another part of the oath is that the : amateur dabbler in sparks will cease to t . trouble the air with his messages when important ones are being sent. De- ' spite the restrictions, fully 90 per cent of the amateurs who have applied for license have successfully passed the examinations. There is also a long list of instructions instruc-tions for the control and di.ection of operators. The wave length must fe of a certain length or a normal sending and receiving' wave length must be given. There are exceptions, however, but the character of the nicsi;.ges in such exceptions must be clearly defined. defin-ed. When the international sign of distress S O S is giver, the statit.n on shipboard may be turned to create a maximum radiation. All stati.ms are required to give ab-. solute priority to signals and radiograms radio-grams relating to ships in distress; to cease sending on hearing a distress signal and, except when engaged in answering or aiding a ship in distress, to refrain from sending until all signals and radiograms relating thereto are completed.. When the United States subscribed to the Berlin conference it made it necessary to change the calls both of the commercial and amateur stations. The calls beginning with, KOA to KZZ inclusive, and those beginning be-ginning with N and W have been assigned as-signed to the United States. So far as possible the government stations will begin with N and the commercial and ship stations of the Atlantic coast with IC, and those on the Pacific coast with W. A system of numbers has been adopted for amateur calls and will be assigned by the radio inspector. |
