THE, EVENING WOKftiPr FRIDAY, MAY 26, 1922.
THE EVENING WOf?LI)S SERVICE By Capt. Robt. Scofield Wood D. F. C, M. C, Croix de Guerre with four palmi; formerly Commander 167th Squadron, Royal Air Forcet. POLICE RADIO NIGHT AT SHOW. In addition to tho regular programme which la being followed at the Radio Bhow at the 71st Regiment Armory, the Follce Department Aviation Corps will atago a special feature of their own under tho direction of Major C. 12. Wright, who Is In charge of tho radio education of the cadets. Duilng the vcnlng tho lOtli Regiment 1'ollco Do prtment Band will render a varied programmo of popular and operatic music. During the afternoon Major AVrlght, In ' one of tho corps' newly hi qui red planes, will fly over New York City nnd tho suburbs' and distribute Identification bombs. In this way the Follco De-Dart ment will test tho adaptability of the aeroplane for pojlcc work. When a criminal with a record Is nt largo nnd wanted by tlio police circulars contain In? tho description and plcturo of the criminal will bo thrown broadcast from tho planes. In this way people for miles around are advised almost Immediately. Each of the bombs dropped from the piano to-day will bo numbered and corresponding numbers will be drawn from a box by Major Wright at the Radio Show to-night. To the persons holding the two lucky numbers will be trlven a complete radio receiving s&tc The first prlro will bo n parlor set, which has been donated by John Firth, and the second prize will be a set do nated by the New Era Company. POLICE BOOTHS TO HAVE RADIO SETS. Radio hao been called in to help solve many problems that seem impossible In the light of ordinary affairs, and It has come to tho aid of Innumerable arts and sciences. So helpful has it been In Us various applications that the Po lice Department of the City of New York has decided to irtotal radio receiv ing seta in the police booths through out the city, broadcasting from Head quarters the information that will help curb tho crime wave. In this way it is hoped to have every road und exit from the metropolis covered so that alarm bulletins concerning all criminals who generally take to the road and the country after committing a crime will be received by the patrolmen, who will be on the outlook. This new method of direct communication to all parts of the city la expected to be the Nem esis of the auto thieves ad bootleggers. It looks as If the lawless were In for a bad session between aeroplanes and radio. BUFFALO GETS ANOTHER RADIO STATION. W O R, the radio station of the Fed oral Telephone and Telegraph Com pany, has otarted operations in the City of Honeymoons and is giving, after noon and evening concerts. A very In teresting programme was staged by this new station last night In which many prominent opera stars partlcl rated. This station which la broad caatlnr on the regular 360-metre wavo length has a dependable radius of 700 miles and can be heard in this part ot tho country during the intermission nerlods of our local stations. With a few moro high-powered sta tions with operating radii of between 700 and 1,000 miles, it will not bo long before there will havo to bo somo inter district regulations to complicate mat ters. APARTMENT HOUSE RADIO TROUBLES. The widespread Interest In radio and Its ranld crowth havo developed many situations Mhat are not understood by the averago new-born fan. In the con gested district these conditions become ncccntuated and very nam to nan die. The apartment house radio ques tion Is one which landlords and tenants are trying to solve In such a manner as to bo agreeable to all concerned. Where onry one or two aerials have been rjlaccd on the roof, there Is not much trouble, but It is Impossible to keep the numbers limited. So, on some houses, we find as many as twelve and fourteen. Which gives rise to a pecu liar situation which Is tho crux of the situation In the thickly populated sec tions. When several sets start to oper ate at once, the Incidental waves and lirtat notes that are set up by the os dlatlons of one or more tubes Is suffi cient to spoil the reception of all of the other sets, not only on the same roof, but for several blocks around. What actually happens In language that all can understand Is that one or more of tho sets reverse and uncontrollably become transmitters. There Is no way In which this dis tressing condition can be remedied where outdoor aerials are used. The only so lution lies In the use of the indoor loop aerial. It Is useless and hopeless to try to remedy the condition by changing the direction of tho aerials or to try and work several sets from the one aerial. The present day apartment house radio situation offers a fruitful field of experi ment for tho radio engineer. Owners of apartment houses after conferring with engineers hesitate to give permission to tenants to erect aerials on the roof so as to keep peace In their houses. Hope Hampton, the movie actress, has taken a decided Interest In radio and has had a set placed In her dressing room at tho studio and also In her home. Sim has become sdtnthuslastlc that she will devote tho hotter part of Saturday eve ning at tho Radio Show, where she will be seen In The Evening World Radio Club Hooth, where she will enroll new members In the club. who has written the results of an n perlment for the Radio News and which is Known to produce good results, "There has come n. rlemimil fni Itin reproduction of radio speech and music so mat moy may bo heard with the same volume as the ordinary phono graph. The public has gono further urn aemanaed that It be produced wltli a minimum of distortion. The averago amateur has been deluged with requests from neighbors, friends and his own Immediate family to hear the pro- Kitwmnc, onu uie loud speaker has como mo general use for their reproduction. iiowevcr, no loud-speaking device, either electro-dynamic or electro-magnetic, can reproduce or give off more energy than Jt receives, consequently amateurs have been casting about for nininons or obtaining additional ampli fication. Some have Increased tho num ber or stages and find that tho desired results are far from satisfactory, bo caiuo using the ordinary type of receiv ing or nmnmyinir tunes the actual inlf of output Is soon reached, usually with three Stages. Mllltl.atnirn nmnlMlora using over threo tubos certainly mnko lor reproduction of weaker signals, but still do not give .the desired Increased output. "The real way to obtain nnwnr or in creased output is to use tubes which rnn designed to carry heavy loads. These tubes nro available In tho power tubes used for transmission to-day, and all of uie standard types now on tho market make excellent amplifiers when used with their raised nlato voltaeea. Tf tho amateur will mibstltute theso power i i ues ror otners in ills amplifiers and then apply a higher piato voltage than .ie ordinarily uses for this purpose on tho regular tubes he will find his output enormously lnereancd. in thl may iv the Ufo of only two or three ataees. a powerful output may be obtained. it used to bo thought that power iudcs were not sensitive enough to handle the feeble Inmulses brouarht to It and that it was necessary to bring ine original signals through at east iwo stages of ordinary amnllflcn lions to obtain uny results. Ex perlments haw proved that this Is not. the cast! nnd that a power ampli fier using 5 watt tubes with 350 volts on the plates may be attached to a crys tal detector through tho medium of the proper Input coil and very excellent re sults obtained. This means that all stuges of amplification may bo power tubes each with tho same voltage, thus simpiyrying the hook-up. One thing must he watched when using power tubes for amplifiers and that is make sure that the amplifying transformers in the amplifying unit will stand the voltage used so that there will not be any chance of a burn out occurring. In the power amplifiers now available special transfer colls are Incorporated so that no danger is caused from that source, as theso coils will stand over 500 volts without danger. 'The transmitting tube Is also much freer from distortion than lower voltage tubes and when used at or slightly be low their rated voltage will give a minimum of distortion, which is the de sired goal of nil who listen to wireless music and speech. CONCERNINQ AMPLIFICATION. The ever-present shortage of radio material, the excessively high price of the little that can be had, and the radio fan's Inborn desire to experiment, are. directly responsible for some of the most useful "wrinkles" that have been evolved and which are Invariably tried under all conditions by thousands of fans. The desire to reproduce the sounds with as little, distortion as pos sible has been the field In which much has been done In the way ot experi menting, but very little accomplished. Ixud speakers are at best horrible things to listen to unless working under Jdeai! conditions. Salesmen for various makes of loud speakers have a pet phrase which Is calculated to convince the average prospective customer: "Nothing comes out of this horn that is not put In It" but It is hard to believe that statement when the remits are heard, No horn produces the sounds perfectly and there Is to a largo degree a certain antotint of truth In the sales man's story, so we will lake a look nt a method that ha been evolved by ltrbtrt B.
