PHOTORADIO SEEN AS AID TO ARMIES; Transmission of Pictures § Will Extend Vision of F Staff Officers. . BY CARL H. BUTMAN, Vith the recent rapid improvement iof radio circuits it is now feasible to dia automatically receive pictures, grams and written or printed mes- sages over extensive distances, ac cording to Capt. R. Signal Reserve Corps. inventor of the Rad system of transmittin pictures, printed messages and dla- grams via radio. points out the wili- -alue of this new phase of radio. tary One of the first aims back of the long efforts of experts to transmit in- was to provide military authorities with the ability to send autograph copies telligence via the ether, he say: of messages and diagrams so as to insure prompt. accurate and reliable confirmation of orders. Modern, commercial radio transmitting and veceiving apparatus is readily adaptable to military and naval use, especially in time of war, 1t s understood. In this connection it will probably extend the vision of the commanders-in-chief and thefr sub- commanders so s to cover wide fields of operation on both land and With this radio apparatus aloft by aircraft it is probable that in future battles aerial views of the maneuvers, showing the several ships of units in action ¥ be placed be- fore the general { within a few minutes No more will staff offi- cers have to imaxine the positions of their units with relation to the enemy Sketches and diagrams drawn from over the lines, or photographs of their actual positions. will be available con- tinually for careful study and analy- sis. Discussing some of the military ad- vantages of vicual and authographic reproduction via radio. Capt. Ranger savs that there is nothing to prevent tha carrying of this plan as far as relaved dots and dashes of radio have been extended. It makes possible the transmission of dispatches to agroun of recelving points simultancously, and as the receiver is much less com! plicated than the transmitter it makes the problem of handling receivers in the field less difficult.

CHICAGO, May 22.—Radio has be- come the *right-hand” man of many a parson. Adoption of this vehicle of gospel ‘sprmdlng by a latge number of church | dignitaries has resulted in religious | programs commanding a greater block of the ether. Where congregations were counted by hundreds, the mes- sage now goes to millions. Where a few pulpits timidly ventured into the air, their pastors now preach by the wholesale. How extensively this messenger has been employed in behalf of religion is disclosed in country-wide reports, Dr. Cadman Urges Use. “Properly used, radio presents an amazingly wide field for reasonable propaganda of the great truths we hold in common,” said Dr. S. Parkes Cadman, Brooklyn, president of the Foderal Council of Churches, who each Sunday is heard over a chain of stations that stretches nearly across the United States. “I have found it an immense help ' in reaching countless numbers of peo- ple who have no definite affiliations with the churches. They are not irre- ligious. Far from it. They are deeply moved by spiritual realities and are a very large group presenting a fasci- nating field for religious enterprise. “The radio also has been of untold good to those who through age or physical infirmity arve upable to par- ticipate in stated religlous services. Their testimony to the benefits they have received is of such volume and qQuality as to convince me that i€ the SERVICES OVER RADIO {Pastors Who Formerly Counted Flocks by Hun- dreds Now Reach Millions Through Use i of Modern Medium. radio industry existed for this pur- pose alone it is amply justified.” The Greater New York Federation of Churches has been a consistent sponsor of the use of radio in church work. Thres hupdred and seventy- four ministers here broadcast special services in 1925, and this number will be increased this year. Dr. John Roach Straton, pastor of the Calvary Baptist Church; Dr. Dan- fel A. Poling, Fifth Avenue Marble Collegiate Church, and Bishop Wil liam T. Manning, Episcopal diocese of New York, have been among the leaders. Rabbi Stephen 8. Wise speaks in behalf of charitable and edu- cational causes, but does not broad- cast synagogue services. Broadcasting of church services has develoned rapidly throughout New England, with encouraging reports. One Bogton church, Tremont Temple, Baptist, controls its own station. The Chase Memorial Baptist Church, Phil- adelphia, recently selected a new pas- tor and immediately broadcast the call to the minister. Undenominafional Chureh. Philadelphia has an undenomina- tional radio church, with John W. S8tockwell as minister. He gave up his pastorate to devote all his time to the new work. Rev. Howard O. Hough recently was installed as pastor of a similar parish in Portland, Me. After two vears of broadeasting, Dr. A. Gordon MacLennan, pastor of the Bethany Presbyterian Church, Phila- delphia, said his morning aulilence had shown no noticeable change “elther up or down,” but that in the evening toly, 200 strangers, to ehurch?" STATIONS MARKED BY SPORTSMANGHIP “Stealing” Programs, Filch- ing Wave-Lengths and Such Things Held Non-existent. Spertsmanship and a spirit of fair lay among the broadcasters of the 'nited States comprise one of the pre- dominant features of American radio, according to W. D. Terrell, chief radio supervisor of the Department of Com- merce, Aside from the few test suits insti- tuted to determine the extent of the authority of the department, and occa- sional matterings of unrest in the ranks of a small minority of stations, the large body of more than 500 sta- tion owners have worked together and with the department almost as one for the improvement of broadcasting and the sclence of radio. Stealing” programs has been prac- ticed seldom if ever in the four years of broadeasting, Mr. Terrell said, de- spite the lack of legislation that would prevent such action. In the three years that the chain program has heen one of the principal factors of broadcasting, no attempt to retransmit this high-grade entertainment by a station outside the chain has been re- ported to Mr. Terrell’s office. The only attempts at rebroadcast- ing programs have always been car ried out with the mutual consent of the stations involved, and a gentle men's agreement prevails regarding the unauthorized, use of program ma terial booked at4the larger and more influential plants. Even with the court decision made recently in Chicago, which held that the department is without authorlty to prevent stations from operating on an unassigned wave-length, the great majority of atation owners have con- tinued to recognize the department’s wishes, and so far have not attempted to transgress from their conduct dur- ing the early days of broadcasting, Mr. Terrell explained Whether this spirit of sportsman- ship will continue indefinitely cannot e determined, Mr. Terrell said. The broadeasting fraternity as a whole s cxtremely anxlous for radio legisla- tion that will let it know where au. thority rests so that it may make its plans for the future, LIGHTHOUSES GET RADIO EQUIPMENT Gifts Héve Brought Pleasure to Remote Stations, Says Secretary Hoover. of the public in con- tributing radio equipment has result- ed in equipping all the more remote and isolated stations of the Light- house Service of the Commerce De- partment with radio sets, Secretary Hoover announced vesterday. Mr. Hoover said, in a statement to the press, that about 381 receiving sets and 100 head sets have been received. His statement follows, in part: *Mr. Putman, commissioner of light- houses, states that the men in the service who have received sets sin- ely appreciate the kindness of the press in prevailing upon some of our enerous citizens to make the dona- tions which have so greatly improved their conditions. Letters coming in from the light- keepers indicate that the sets which the department has been able to dis- tribute thus far are working very sat- isfactorily. The keepers report that they are getting clearly and distinctly the words of prominent speakers, musical entertainment, good Sunday sermons and the like. One keeper in expressing appreciation describes his radio as ‘the most company of any- thing I have ever seen in the light- hy service." n addition to being entertained, ihe keepers are making use of the sets in receiving important messages and in the reception of weather reports and time signals. When they become proficient in reading,code, many of the sets may he of vital use in receiving urgent code messages.” = the majority of whom have “listened in" previously, are met in the congre- sation. When the pastor of the Church of God, Pittsburgh, was called from the city his congregation installed a loud peaker in the pulpit and picked up the sermon of Dr. J. A. Orr, preaching in the First United Presbyterian Church. Plan Used in Capital. In Washington the Federation of Churches has.been broadcasting two and a half years. Church officials are pleased with the results. Church broadcasting was inaugu- rated in the Middle West as early as 1 when a noted divine addressed the Chicago Sunday Evening Club with a microphone before him. Hu- morists immediately pictured lazy householders lying abed Sunday morning and attending church by twiddling the dials. Radlo services &enerally outlived the jests, however, and spread to other sections of the country. The Sunday Evening Club received a contribution from invalid sailors on the United States battleship Texas, harbored at Martinique in the Carib- bean Sea, after they had listened to services over the radio. Church Allied With Card Firm. An alllance between a church and a playing card manufacturer fostered ether evangelism in Cincinnati. Radio as a medium for the develop- ment of spirituality is proving a force so tremendous that its powers can- not vet be defined or appraised, sald churchmen of the Western States, where the microphone is widely used. The general opinion is that eventual- ly radio will bring into the church thousands who have drifted away and ‘many others with no denominational connections. One of the numerous Western sta- tions is KSL, Morman Temple, Salt Lake City. Old St. Mary's Roman Catholic Church in 8San Francisco occasionally broadcasts through pon- sectagjan stations. Southern Pastors Active, ‘What is true in the East, North and West is true in the® South. There radio broadcasting is generally in- dorsed. P Dr, James I. Vance, Nashville, pres- ident of the board of forelgn missions, Southern Presbyterian Chyrch, and former moderator, believes in “the radio thoroughly.” Likewise do Bishop Abiff Boaz, Dr. 'Franklin Smith, Dr. Stonewall Anderson and Dr. W. W. Pinson, all prominent in the ~“Methodist Eplscopal Church South. In reply to the contention that broadcasting decreases church at- tendance, Dr. Smith’s reply is this: “Who or what could keep a woman with a new hat or dress from going No. 65—Nothing to Amplify. Occasionally, I find Smijth at his favorite radio store looking over the new equipment as well as the things that are not so new. At such times, I figure he is having trouble of some kind, When life runs smoothly there isn’t much incentive to make changes and grope for further progress. So with radlo. Smith wanted bet- ter reception. That was not surpris. Ing. The thing that makes this inci- dent worth recording was his idea of how he might be able to obtain it. I watched to see what he was particu- larly interested in, and was not sur- prised to discover that an audio am- plifying unit had caught his eye. [ could picture his mental reaction to the sight of this compact acces. sory to the simplified radio set. “There’s just the thing I need,” he thought. “Something to amplity the weaker signals. The device, added to my set, should bring in the coast.” A few moments later he had emerged from the store with the amplifying unit under his arm neat- ly wrapped up. “I've got something that'll makq WEAF sound like NEAR,” he boast ed, suddenly discovering that I, too, was looking In the window. “That's fine,” 1 replied. “How much do vou want for it? I'll need one of those in a new set I'm building. Il never be any use to you.” Smilth's dreams of super-reception vanished. “You've got two stages of amplif cation on your set already,” I has- tened to explain. “If there's anything to be picked up, if the wave intércept- ing system of your set is on the job and you know how to tune you can get all the volume you need with your machine, and all the volume you can stand in a small room, with a small loud-speaker.” Uses Two Stages. Ah, but my plan is to use the second two stages of amplification when I'm tuning in on a distant or weak station,” he explained. “That’s where I need this amplification.” “What are you going to amplify?” I asked, leading him around to the facts by degrees. Smith thought this over a moment and said something about making a lot out of very little with the aid of the four stages of amplification. He saw the point, however, when I show- ed him that it is folly to try to implify something that doesn’t exist. When there’s nothing to amplify all the amplfication apparatus in the wol will not help. As a matter of fact, additional stages of amplification simply giv noise—amplification of the tube noises Although the use of radio at sea was the first practical service visual- ized when radio communication was developed, little concerning this phase of radio i known today nor is the International accounting method gen- erally understood. » When considering radio. the ave age person thinks first of broadcast reception and probably next of instal- lations on ships, which bring to his mind radlo’s incomparable value in the safety of light and shipping at sea. According to H. F¥. Coulter, chief of the United States Central Bureau, however, radio has a very high social and commercial value, and its use in this respect during the last few years has increased to an ex- tremely large proportion. Discussing the basic points of the international methods, Mr. Coulter pointed out that, aside from determin- ing international methods, one of the main purposes of the international radlo convention in London in 1912 was to determine methods by which any radio station, ship or shore, par- ticipating in @ commercial radio tran mission, should receive its pay for service rendered. The London co vention, therefore, made each nation responsible for the ships under its registr in order to obviate the necessity of other nations collecting their charges from various private rces. sn;’r\roerder that a coastal radio station recelving a message from a ship might identify the ship's natlonality, call letters were assigned in three and four letter groups, the first letter of the group identifying the nationality. For example, the United States was assigned the letters/K, N and W. 4 coastal statlon receiving a message from a ship using a call beginning with any one of these letters would automatically identify it as under the maritime registry of the United S o, l::!:ch month the coastal station or its head office sends a bill to the proper office of the nation which reg- isters the ships with which it has handled trafic. The station itemizes each message from ships of that na- tion and shows the amounts due f{t for its coastal service and any charges which accrue for telegraph or cable relaying beyond its station to the message delivery point. The coast stations also list the credits due the ship for messages accepted to addressees on board, and a net set- tlement is effected by the creditor nation. ‘The balances in practically every case are in favor of the coastal service, as the greater number of mes- sages are sent from ship to shore. The monetary units of different na- tions are not universal and, in fact, many of these currencies have no flexibility. - In 1875 at St. Petersburg, consideration was given to the use of a currency which would fully compen- sate eachh telegraph system for the services it had rendered. Considering the wide fluctuations which might take place within the various mone- tary systems of different countries, the convention determined to use the gold franc. Therefore, all accounts are stated in gold francs, each admin- istration notifying other administra- tions through the central clearing bureau ate*Berne of the value in ite currency which it will collect in set- tlement. This custom was found to be efficlent and it was embodied in the London radiotelegraph conven- ion. g This gold franc, of course, does not really exist; it is the unit of interna- tional finance and circulation in radio accounts, being worth approximately 19 8-10 cents, United States currency. An example will probably make clearer the method by which this franc is used: Assuming that the French administration accounts to the United States for 1,000 gold francs, the equivalent of whigh in United States currency is $188, the United States would collect approximately $198 on the account. However, when settlement {s about to be made to the French administration it will be impossible to purchase sold francs, and assuming the value of the paper franc to be about 5 cents on the date the exchange is purchased the French administration would receive by draft the gold equivalent in approximately the sum of 3,860 francs. Since the United States is a signa- tory to the London radiotelegraph convention, to which convention over 80 nations are adherents, it maintains a central bureau or clearing house, under the Bureau of Navigation, De: partment’ of Commerce. This office receives these radio accounts from the other nations and collects on their Dbehalt the amounts which are dup L} John Smith and His Radio BY FREDERICK C. RUSSELL Car owners throughout the world have followed John Smith in his daily motoring—and have benefited thereby.

Beyond that you can enlarge upon signals to a point where distortion takes place, but If these signals are not sufficient- ly energetlc to start with, the appar- ent amplification process simply means distortion. “If it were posible to follow the plan you have worked out all the radio ‘manufacturers would have to do would be to provide a surplus of audio amplifying tubes and transform- ers”” 1 tola him. “Considering the sales value of such sets, judged by their ual performance, this could be accomplished at comparatively little cost. It would be a wonderful sales scoop. But it isn't done. And that's the best answer I can give as to why you can't expect to do it. To Improve Reception. “If you want to improve reception, the place to start is at the source of the signal strength, not at the other end. I do not say that amplification is not important or that you cannot 2dd a power tube and get better re- sults under certain conditions, but I do say that the logical step is to look to increasing signal strength as pick- ed up by the waveintercepting =ys- ! tem. “It is the same principle you apply [to your car when nt to_in- ease its hillclimbing ability. You are justified in greasing the wheels and in seeing that the brakes do mnot drag, but the main thing is to have the valves geating properly and the carburetor mixture right. In an automobile it is possible to step up power by gearing the car lower the rear axle, but this is never real efficien You can step up the final product of your receiving set through additional audio amplification, but that does not increase the real range and sensitlvity of your set. “In a nutshall, the idea is this: The grid of the detector tube controls the audio amplifying system, but if there is not enough signal strength to en- able the grid to set off the rectifica- tlon process you will zet nothing but silence, regardless of how many stages of amplification you use, how many tubes and how much battery energy, If you can get the grid to start something vou have something to work on in the amplifying line, and it usually happens that you get bet- ter results by building up signal strength before it reaches the erid than by trying to make a. lot out of very little through audio amplifying."” Next Week, No. 66: John Meets | the Jack.

RADIO GOSSIP AND NEWS | them for service from American ves- sels. 1t is interesting to note that for this particular class of traffic alone, mearly 2,000 accounts, each covering periods of from one to six months and aggregating in total well over -$300,000, were handled by .the United States for the various foreign nations during the fiscal vear 1925, not only for those signatory to the radio convention but for others as well. These accounts were each seg- regated and sent out to the varfous American ship owners and radio oper- ating companies, over 15,000 individ- ual accounts being collected from American companies during the period mentioned. In general, each nation maintains a clearing house which cares for its mobile or ship stations, and it is to those clearing houses that each com- pany operating coastal stations sub- mits its radio accounts for settlement. It is estimated that American veb. sels during the course of a year send to foreign coastal stations in exc of one million messages. Without taking into consideration the various point- to-point radio services involved. such as transmissions between fixed points in different countries, the growth of maritime radio from 1912 to the pres- ent date can be more readily visual- ized by the fact that the amounts paid to the foreign administrations in the fiscal year 1913, were but $2,500 as compared with an amount 100 times greater during the fiscal year 19I5 Stations Reduce Interference. Kix " broadcasters located in and around Chicago have equinped their transmitters with piezo crystal oscil- lators calibrated to their assigned wave lengths, in an effort to decrease the interference among the many neighboring stations. These devices tend to keep a station in its assigned channe! and make for sharper and standard transmission.
