"2 PLANNING TO RELAY WORD OF MACMILLAN Canadian Government Steamer Arctic Is Leaving for Baffin Bay. SHORT WAVE TO BE USED Hopes to Get in Touch With Ama- teur Stations. ay | Special Dispatch to The Star. i TORONTO, Canada, June 25—Wil- liam Choat, local radio amateur and radio operator for the Canadian gov- ernment steamer, Arctic, which is leaving Quebec July 1, on her annual trip to Bafiin Bay, may be the first amateur operator to relay back to Canada and the United States the complete details of the winter ex- periences and home-coming arrange- ments of Capt. Donald B. MacMillan, Arctic explorer. The departure of the Arctic, un- der the northwest territories branch of the Canadian department of the interior, comes at a time when the arrival 'of daylight in the far north is beginning to shut off the radio contact between MacMillan and radio amateurs of the American Radio Re- lay League in Canada and the United States. Messages Grow Scarce, The radio messages that have come from Donald Mix, the explorer's radio operator, last fall and winter have become ' gradually less frequent s darkness began to leave the polar regions. Of late, there have been only a few weak messages that have suf- ficed to show that Bowdoin's crew have come through without hardship. The last one told of the explorer's plan to start for home soon. On its annual trip the Arctic which this time is in charge of J. D. Craig, M. E. I. C, and Capt. Bernier. famed _Canadian explorer, sails far north as Etah, Greenland. Las fall on their arrival in that harbor the Arctic's crew found the Bow- doin there, and one of them too a snapshot of MacMillan's little schoon- er as she lay at anchor near tie shore. TI ar the Arctic will carry a short-wave 1. C. W.. outfit which will_enable its operator to transmit on the amateur wave lengths between 100 and 150 meters. This equipmnet 13 in addition to her two regular sets, consisting of a standard 600-meter 2-k. w. spark transmitter and a con- tinuous wave transmitter working on a 2,100-meter wave length. Tests With Amateurs. The radio branch of the depart- ment of marine. which looks afte: the radio equipment on the Arc for the department of interior, sires to carry on tests with ama- teurs of the American Radio Re: League in Canada and the Uni States and had the special shor wave equipment installed for this particular purpose. The call which has been assigned to the Arctic is VDM, while that of MacMillan's ship is WNP. Spe- al permission has been granted for 1 Canadlan licensed amateur st tions to use the wave length of meters during the specified hour: although transmission on this wave will not be permitted for any other communication. In order that amateurs will know when to be at their stations for com- munication with the expedition, a def- inite schedule has been arranged, dur- ing which Mr. Choat will listen for siz- nals. He will stand watch on the short wave length daily, except Wednesduy and Saturdays, from 11 p.m. to mid- night, eastern standard time. Saturdas, however, the hours will be extended from 11 p.m. to § am. The Arctic is a_wooden ship of tons gross, and carries sails in additio: to her engines. As it is impossibie to insulate the heavy guys which hold the three eighty-foot masts the ship is not regarded as ideal for radio work, al- though it is expected that this handicap can be overcome by the use of high power. The ground for the radio equipment is provided in the form of a copper plate secured to the side of the ship. If this 18 torn off when the vessel encounters ice floes it will become necessary to utilize the engine propeller. KFI WILL ACQUIRE 5,000-WATT POWER Los Angeles Radiocasting Station Plans to Be Most Power- ful in Nation. Special Dispateh to The Star. LOS ANGELES, Calif, June 25— Plans to make KFI a super-power station and the most powerful in the United States are being made by Earle C. Anthony, Inc., owners and eperators of the statior. New appa- ratus which will be installed in the station will give it a power of 5,000 watts, The purpose of the Anthon: pany in replacing its present 500-watt equipment Is to increase not only the range of the station, but to increase particularly the quality and rell. ability of reception. The secret of successful quality reproduction is to put out suflicient power to bring the modulated carrier wave into the re- ceiving set with sufficient strensth to operate the detector and the loud speaking devices from the ecnergy actually transmitted through the aip instead of using high voltage amplifi. gation, which distorts and loses qual- The present governmental law mits but 1,000 watta to he ma Tero the antennae, therefore, KFI will be oberated at 1,000 watts, with a r scrve of five times that amount aval ab or special occasios the law is later modlfi:;. Raimicits Staft to Be Tripled. In order to adequately take care of the new equipment, the Anthony per- sonnel of engineers, operators and prosram managers "will be tripled. he set contains special transformers and special devices to Increase the roundness of tone quality. The voice Is amplified and turned into radio frequency by the same 500-watt equip- ment as is now in use by KFI, but instead of this 500 watts ®going into the antennae, as at present, it is put into two watercooled amplifying tubes, which are supplied with & poten- tial of 10,000 volts direct current from three water-cooled rectifier tubes, and the amplified modulated the area in square feet of the pres- ent equipment, and is the latest de- vice used, to ‘be a duplicate of the American’ Telephone and Telegraph Company’s station, WEAF, in New York City. The added power will insure satis- factory reception during the daytime, and will mean an absence of fading during the summer months, which is now one of the greatest drawbacks to DX recelving. Total cost of the extra equipment, now under construction, will approxi- mate $75,000 more than the present towers, studio and buildings, with an vperating expense of approximately $10,000 per month. An additional studio will be constructed, permitting one group. of entertainers to be prepar- Ing while another actually broad- casts. Anticipating the full 5,000-watt equipment _ being available, the Anthony company plans to remove the set to silltops in the outlying dis- tricts of Los Angeles, in order that Jhe city iself will be sprayed from the outside without interfarence due to power lines, street car 1fhes, mgh- tension lines and the like. = Also the number of remote control stations w11l be doubled, in order that the sup- porting program may be the best in the United States.

Presenting the first of the summer boxing bouts, station WJZ will trans- mit Maj. J. Andrew White's descrip- tion of the feature fight of the Milk Fund contests direct from the Yankee Stadium, commencing at 8:30 o'clock tomorrow night. The main bout of the evening, between Gene Tunney, light-heavyweight champion, and Ermilio Spalla, heavyweight champion of Kurope, promises to be one of the best of the year. Tunney is making a try for recogni- tion as a.contender for the honors now worn by Jack Dempsey, while Spalla has somewhat similar hopes. Spalla fought Luis Firpo in Buenos ‘Aires, the fight lasting fourteen rounds—Ilonger than any one eise has ever gone with Firpo except Demp- sey, who went much farther in a shorter time. Tunney expects to rush the Argentine heavyweight off his feet and put him to sleep in rapid style, giving the bout the as- surance of a maximum amount of pep and excitement for the fight fans listening in. J. Andrew White's description of boxing contests have placed him in a class by himself—he is the un- challenged champion of sport an- nouncers, and his powers of observa- tion and description will add much to the success of the broadcasting.

LEESE OPTICAL co. 614 9th Selecting and Mounting the Induc- tance Switch—Part II. After having selected a good in- ductance switch, the next step is to be sure to know how to mount it properly for best results. This is a very simple matter if attention is paid to several detalls. The first step is to determine just where the shaft of the switch is to be mounted. The next step is to drill a hole large enough for the mount- ing bushing. Then fasten the bush- ing in place temporarily with the head of the bushing on the rear of the panel and the nut on the front of the panel. Now comes the point which is a puzzle to many fans—the location of the center line along which the Afi 'Y 1 switch points are to be placed. Some fans try to do this by using a pair of dividers or a compass opened to approximately the distance between the center of the switch shaft and the end of the contact arm. That method will not give accu- rate results, Above all, never use a compass with the needle point set at the center and then scribe a pencil line for the centers of the switch points. Remember that while lead is a poor conductor, having consid- erable resistance, the line acts as a high resistance connector from switch point to switch point. The best method is as follows: After you have fastened the bushing in place, bend the switch arm slightly away from the knob and insert the shaft in the bushing with the knob side on what is to be the back of the panel. Then, pressing the knob to- ward the panel and being sure that the end of the contact arm is in con- tact with the panel, turn the knob back and forth and scratch a light line on the panel as shown in figure 1. * Mounting Switch Points. The line is the center line of the switch points of that switch. The next step is to measure the center- to-center distances at which to drill the holes for mounting the switch Argentines Hear KDKA’s Program; Feat Unequaled BUENOS AIRES.

SALT LAKE CITY, Utah, June 25.— Pope Pius has conferrad the papal decoration “Pro Ecclesia Et Pontifice” upon Mrs. Arthur H. S. Bird of Salt Lake City, says a telegram to the Salt Lake Tribune from Rt. Rev. Joseph S. Glass, Bishop of the Catholic Diocese of Salt Lake. Mrs. Bird, vice president of the Na- tional Council of Catholic Women and seven times president of the Catholic Women's League of Salt Lake, is the only American woman to receive the high honor. FIFTEEN MINUTES OF RADIO EACH DAY By JOSEPH CALCATERRA, Radio Editor of Popular Science Monthly All Rights Reserved. Reproduction Prohibited. Fig-2 points. The tendency of most fans seems to be to mount the switch points too closely together. Mount- ing the switch points too closely to- gether is bad practice, both elec- trically and mechanically. ‘To lessen the capacity and increas the resistance which is bound to ex- ist between adjacent switch points, it is best to mount them as far apar! as possible within limits which are determined by~ the width of the con- necting end of the switch arm. Many fans place two switch points close together and measure the dis- tance between centers of the switch points, allowing a _short space between the heads of the switch points. Later, when they come to mount the points they find that the long dlameter of the hexagon nuts, which are used to fasten the points in place is greater than the diameter of the head of the switch point with the result that adjacent nuts-touch each A Fig.3 other or at best are barely separated. In measurig the center-to-center distances between switchpoints follow the method shown in Fig. 2. Take two switch points with guts threaded on them; hold them so that there is a space between the two nuts and then take the center-to-center distance be- tween switch points with a pair of di- viders. This distance can then be laid off on the line scribed by the switch arm Nuts Must Be Tight. The nuts used to fasten the points in place should be well tightened. Usually it is best to use two nuts so as to lock the point against any po: sible loosening tendency caused by the action of the switch arm in mov- ing from point to point. In some switches the contacting end of the switch arm is a straight line as shown in Fig. 3a. In many cases you will find that best results in tuning are sometimes obtained witr the switch arm con- tacting or bridging on two adjacent switch points as shown in Fig. 3b. In that case better contact will be ob- tained if hte end of the switch arm is rounded with a file to the shape shown in Fig. 3b. This rounded form also facilitates the movement of the switch arm over the switch points NEW PICK-UP STATION OF KDKA TO BE BEST Pittsburgh Post Studio Being Changed Into One of Most Modern in Country. B . Special Dispateh to The Star. PITTSBURGH, Pa., June 25.—When changes now under way are made in the Pittsburgh Post studio of the world's pioneer broadcaster KDKA, the famous Westinghouse station will have a pick-up studio perhaps better than anything of its kind In the 1 world. 1o The next Pittsburgh Post studio is now being installed in a separatc: | operating room, builtin to the main | studio, in which will be installed a!l apparatus necessary for the studio | operator to change over microphones or make adjustments to the amplif ing apparatus. The new operating room is noise- proof and will have a two-way con- nection with the transmitting station located in East Pittsburgh, fourteen miles away, so that changes made during the operation of the station wllll h; instantaneous. n this operating booth will be lo- cated all the amplifying apparatis and the various switches which are usually seen in the ordinary studio. In order that the operator can see what is going on a window has been built in_the side of the operating room. This window can be closed when the tion is working to permit conversation with the transmitting station operators. H This change is one of < ones that have been made In the Pittsburgh Post pick-up station of KDKA, its first pick-up station, since KDKA' began broadcasting = from downtown Pittsburgh. It is not generally known that E. Pittsburgh, where KDKA is located 1 fourteen miles east of Pittsburgh and that most of KDKA's broad- casting is done from outside points, or pick-up stations as they are called. In broadcasting events from Pitts- burgh and the surrounding district KDKA uses thirty-four pick-up points. GEN. HUERTA KILLED. MEXICO CITY, June 25.—Gen.
