FOUND BY RADIOBY PIERRE BOUCHERON

0NE of the most romantic stories ofthe power of radio is the story ofthe finding of Cleo Archer. InJanuary, 192o, Lester Archer wasa young radio amateur living in

Toledo, Ohio. This was before the day ofwidespread radio telephone broadcasting. Withhis radio set using the Continental MorseCode this young man accomplished in ashort time what his mother, lawyer, andprivate detective agencies had been trying todo for thirteen years. At the age of five, CleoArcher, Lester's sister, had been secretly placedin the Allen County Children's Home of Ohio byunfriendly relatives. To find Cleo became thelife aim of young Archer and his mother, Mrs.Dorothy Archer, and to this end, they visitedother cities and towns in a vain search, mean-while conducting a legal battle to compel thehome authorities to divulge Cleo's whereabouts.

In 1910, this young man, then but a boy inknee pants, became interested in amateur radio,and in a short time he had done what manythousand boys have since duplicated; erected acomplete sending and receiving station enablingslim to converse at ease with local enthusiasts.For the next few years he spent a great dealof his spare time experimenting and improvinghis installation so that he was able in 1920 tosend as far as 1,000 miles with his home-madetransmitter, as well as to receive from the longdistance high power stations at Nauen, Ger-many; Stavanger, Norway, and Lyons, France.

In talking, or rather telegraphing, throughthe ether, Archer's radio acquaintances reachedconsiderable proportions, until they includedmany amateurs from neighboring states. Thegreater portion, of course, he had never seen,but they nevertheless all belonged to the greatfraternity of the ether. One of these radiofriends was Mrs. Charles Candler, of St. Marys,Ohio, who, with her husband, operates thepowerful amateur station "8ZL" now wellknown throughout the United States for itslong distance records.

One evening of January, 1920, young Archerwas "talking" with Mrs. Candler in the corn-radery which radio boasts as its very own,when he conceived the idea of asking for hercooperation in broadcasting the "call" for hissister, Cleo. With the aid of the multitude ofamateurs within the reach of "8ZL," Mrs.

Edison's firstincandescent

lamp

Candler thereupon offered to transmit a generalmessage bearing the girl's description and ask-ing for information regarding her whereabouts.The first radiogram of this nature was sent latein January and was, of course, picked up andrelayed by hundreds of other amateurs through-out the country who were only too willing tohelp in the search' Archer, meanwhile, satnight after night at his receiving set listeningfor a possible encouraging reply. Weekspassed and it began to look like a hopeless taskwhen one evening, the faint call "8KV"(Archer's registered call signal) came fromanother amateur located at Van Wert, Ohio.Following this call, came some words hardlydiscernible, so faint were they, and in whichyoung Archer was able to distinguish the words"your sister." Late at night of the same day,when most amateurs had closed for the nightand local interference had subsided, Archer wasagain able to establish communication withthe Van Wert station and was informed that ayoung girl answering the radioed description ofhis sister was living at the home of a near -byfarmer at Rockford, Mercer County, Ohio.Moreover, this amateur flashed back that hehad been trying to reach Archer for the pasttwo weeks but without success, owing to thelimited range of his sending equipment.

Needless to add, it did not take long forArcher and his mother to investigate the radi-oed report. Much to their surprise and joy, thereport proved correct and the girl was recog-nized instantly as the long lost one.

The story of Archer and his unique use of theether is indeed an achievement to amateurradio of this country. To -day, with our greatand far reaching radio telephone broadcastingstations throughout the country, we have atour disposal, probably, the most effective andinexpensive means of locating absent ones yetdevised, and as the fame and worth of radiospreads far and wide it is quite reasonable toexpect police officials to resort to its use for amultitude of purposes, whether for seeking thewhereabouts of lost ones orfor hunting criminals.

MORRIS N. BEITMANTHE RADIOMAN WHO HELPED THOUSANDS

By Brent Dingman

Anybody who has been in the radioindustry or associated with it the last140 years is familiar with Supreme Pub-lications. You have seen their ads inall the early radio publications, usedtheir books and even completed theirradio course. Most have seen the nameM. N. Reitman on all the publications,but not many users have heard the per-sonal success story of how Morris Heit-man not only started Supreme Publicat-ions, but has helped thousands like my-self and two friends. Each one of usnot only made it our career, but helpfurther our vintage radio hobby.

In 1950 I was a lad of 11-yeara-old and with the help of Glenn DavidBergland, age 8, we built our first tele-phone and telegraph systems out of tincans and green -cotton -covered wire wrap-ped around nails. Dave's dad was anelectrical engineer (pass national pre-sident of REA) and had a large workshopand technical library in the basement.This was nice because I had neither, soguess where we spent our time, Dave knewa lot, because he had been tinkering a-round since he was 6. I was the studentand after these two projects Dave hand-ed me the 1926-38 Volume 1 Most -Often-Needed RADIO DIAGRAM MANUAL by MorrisReitman and the radio course. He toldme to study it, I was ready for tuberadios. It paid off of Dave, he isDoctor Bergland, Department Laser Headat Bell Labs. Another friend collectorAlan Douglas of Mass. related to me howVolume 1 was instrumental in helping himthe same way. Al was given an AtwaterKent Model 20, although the M20 vas notlisted, it was very similiar to theModel 30 and he got it to work. Thatbook was all he had until he reallystarted collecting in 1965 and graduat-ed as an engineer. I know there are alot of persons who read this and havesimiliar career stories, so thank you,Morris for still publishing these books.Who wants to wade through a 15,000 -pageset of J. F. Riders and a ten -foot -shelf of Howard Sama Folders, they quitpublishing their old radio material longago?

Mr. Reitman started his radio en-gineering, teaching, servicing and writ-ing in the late 1920's. He wrote art-icles for magazines on radio and in thedepression there was no payment, onlyadvertising apace, so he prepared somebooklets and sold them in this space.In addition to this he worked for sever-al important manufacturers...Old Belmont,Stancor, Allied Radio, Radolek (remember?)and Lafayette when they were calledRadio Wire Television. He prepared asimple radio course and sold it locallyand by mail order for $1.95 giving thema final exam and diploma. Do any of youhave one? He helped thousands get in-to radio on a shoe string.

Morris taught from 1939 through1941 vocational classes in the Chicago

NEW YORK, OCTOBER 25, 1884.

THE THOMSON-HOUSTON EXHIBIT AT THE INTERNA-TIONAL ELECTRICAL EXPOSITION, PHILADELPHIA.Visitors to the Exposition, upon entering the main gate

and then turning to the right, had their attention attracted,before they bad proceeded far, by a multitude of powerfularc lights suspended above a raised and richly carpetedflooring. Here were displayed a series of finely wroughtmechanisms, from an exposed core of a dynamo to the per-fected machine. This was the headquarters of the Thom-son -Houston Electric Company, of Boston, Mass., whichof late has become widely known for the efficiency of its apparatus and the business -like thoroughness of its system.

In the general exhibit this company bad five dynamo ma-chines in constant action, two having a capacity of 30 arclamps, two more of 12 lights capacity, and still another of6 lights. Besides these there were models of the unfinishedThomson -Houston dynamo, so arranged that the parts couldbe inspected, and other specimens of the latest improvedtype.

To those who had the time and inclination to attentivelystudy this exhibit-and there were many such-conclusiveevidence was presented of its possession of novel and strik-ing features when compared to other systems of the sametype. It was noticed that the hissing and sputtering, socommon in some arc systems, were here reduced to a mini-mum, and the lights were powerful, constant, and steady.

A diminutive dynamo and plant designed by Prof. Thom-son illustrated the system in all its workings far betterthan could have been done by a plant distributed to distantparts of the building. It showed clearly the relations be-tween current, electromotive force, and work. A smalldynamo generated a constant current, which kept aglow sixarc lights, each of the intensity of sixty candles, and by

switching the current it could be made to leave the arclights and supply the requisite energy for an incandescentplant.

The peculiarity of the Thomson -Houston dynamo maybe said to lie mainly in the armature, the construction ofwhich is strikingly original. This armature is made of acast iron hollow shell; and iron wires, forming an oblate

spheroid, surround this. Insulated copper wire in threeseries is wound on this core. Starting at that part of theshaft opposite the commutator, the wire of each of theseseries is led over the longitudinal circumference of the core,and, in order to avoid the shaft, changes its course and re-turns via the opposite circumference of the core.

making a sufficient number of convolutions, the terminal iscarried out to a segment of the commutator, the beginningof the wire being attached to a coupler near that portion ofthe shaft which is opposite the commutator.

A like direction is taken by the second series of wires,which are kept at an angle of sixty degrees with the first,and the third series of wires follows at another angle ofsixty degrees. The initial ends of these last two series areaffixed to the coupler to which the first is attached. Henceall of them are electrically connected. To different platesof the commutator the three free ends are affixed. Thismethod of winding has proved to be very efficient, two se-ries being constantly maintained in the field of force.

By means of a combined motor and generator shown inthe exhibit, the arc light or motor circuit can be made tofeed incandescent lamps, an alternating current being used.The system employed is that of building on the same shaftthe armatures for both the motor and the lighting appara-tus, and any kind of current as to character or potentialmay be taken off.

What attracted not a little attention to this exhibit wasthe running of arc lights in multiple series. This is an in-vention of Professor Thomson, and a very important one,for, a,:t seen at the Exposition, it permits the running of arclights of altogether different intensities from a single cir-cuit, some of them being in series, while others are in mul-tiple arc or in multiple series, and renders practicable di-visions and redivisions of lights as well as the rejoining ofarc circuits.

For the benefit of scientific institutions and the lectureroom generally, the Thomson -Houston Company make ahand dynamo. As exhibited, it showed that it is capableof generating a small arc light or several incandescent lights,.

High School systems. Remember the ear-ly schematics or (pictorial wiring die -grams as they were called) for pre -thirties? The Radio Manufacturera As-sociation (RNA) was trying to stand-ardise the different parte of the dia-grams (by using same symbols). The

symbols and information provided ineach manufacturers Radio Service Man-ual usually was misleading and dif-ferent. It gave the radio repairmanjust enough information to repair theset, but he usually ended up tracingthe circuit out wire per wire and de-signing his own diagram. You can im-

agine how the beginning radio studentfelt trying to learn this and a lot ofthem became discouraged.

Morris applied his practical ex-perience instructing students on howto take a radio set and layout a com-plete wiring diagram using all the man-ufacturers service manuals, and loadsof other related loose information.The sets were usually checked outpoint-to-point under operating condit-ions and new information applied to thediagrams.

This later became Volume 1 1926-38MOST -OFTEN -NEEDED RADIO DIAGRAM MANUALas we know it today. There are over2110 pages covering 600 models such asall popular Atwater Rents, RCA, Philco,Crowley, etc. The Supreme PublicationsTrade Mark of "Theory, Practice and Ex-perience" really stands out.

MOST POPUI AR OF ALL MUSICALINSTRUMENTS

With the Edison factories turning out machines atthe rate of two a minute every working day there is nolonger any question that the Edison Phonograph has'become the most popular musical instrument of thepresent day. Probably more Phonographs are nowsold than all other musical instruments combined.The Edison Phonograph is no longer to be consideredas in the class with those machines against which manyare so prejudiced. Mr. Edison and his assistantsstudied long to determine the cause of this prejudice.Finding it due to loud and unnatural sound reproduc-tions, blatent horn tones, harshness, scratching andother needless noises, they have eliminated every ves-tige of such faults, and produced a machine thatsings, plays and talks naturally, smoothly and withoutscratching or horn tones. It is impossible to comparean Edison Phonograph with any other style of machinewithout realizing that the former is infinitely better.To those who want real music, naturally reproduced,the Edison Phonograph asks no other test than to beplayed alongside of any talking machine in existence.Such a test will win all but those who want noise andare not looking for quality.

RECORDS PUT TO QUEER USESExcept when a Phonograph is turning out some such

pathetic melody as "A Message from Home, SweetHome" one rarely thinks of that instrument in con-nection with real sentiment, and yet it has a use ofthis kind that is growing rapidly all over the world." It has become a common thing," remarked a man inthe business, " for elderly persons to come into mystore, have records made, and take these records offwith them to their safe deposit box to be given to theirchildren after death. It is pathetic to hear a man of

middle age speaking into a Phonograph the speech hewishes his children to remember him by. Sometimeshe has the speech prepared in writing ; again he mayhave simply a few notes from which he elaborates hislittle address. As a rule these remarks are brief morallectures and are usually beautiful since they are sosimple and so sincere.

Fathers of families are not the only ones who putthe talking machine to such sentimental usage nowa-days. It is not an uncommon thing to have a motheraccompanied by a child go into a shop where such

. things are sold to have a Record made of some child-ish speech that will be sent to the little one's fatherwho is a long distance from his family. Only the otherday the newspapers printed the story of a woman inDenver who is dying of a lingering illness talking intoa Phonograph every day that her husband might havea Record of her voice after death came to her. Nowand again one hears of sweethearts using the talkingmachine for the same purpose-a case in point beingthat of an elderly bachelor in this city who begged thewoman he was in love with, but who would not marryhim, to talk into his Phonograph that he might alwaysbe able to hear the sound of her volee. The capabili-ties of the machine were doubly illustrated in this par-ticular instance, since the woman spoke for the Beoordin French.

That the use of the talking machine in this particularmanner is growing rapidly is shown by the increase inthe sales of blank Records, and also of the numbers ofpersons who go into the shops where the machines aresold to not only have speeches recorded, but also tohave messages reproduced. There is never any chargemade for this work beyond the original cost of theblank Records, since such accommodations are recog-nized as being a good advertisement for the machinesthemselves.

That the Phonograph is recognized as an instrumentof some scientific value is fully demonstrated by theaction taken in recent years by directors of the Smith-sonian Institution at Washington, of Harvard Uni-versity, of Yale, and one of the universities at Vienna.At the Smithsonian they are making a collection oftalking machine Records of the various dialects of ourWestern Indian tribes to preserve them against thetime when the Indian tongues shall have disappearedfrom human speech. The Smithsonian people beganthis work as far back as the time of the Buffalo Fair,when they had all the Indians at the Fair speak intothe machines for Records.

In the receiver,Bakelite tubes, threaded,provide the forms on whichinductance coils of highfrequency cable are bank -wound. After assembling,the coils are impregnatedwith an insulating com-pound, in vacuum, andthoroughly baked. The in-ductance switch controls amechanism whereby thedifferent sections may beconnected, completely dis-connected and opened, orcompletely disconnectedand individually short cir-cuited. This arrangementis important for, by it, eachcoil has a natural periodwhen connected which isless than the shortest wavelength in the receiver'srange. The reception ofparasitic signals is over-come, the absorption of de-sired signals by the coilsis minimized, more energyis forced to the detectorand on all wave lengthsthe interference is reduced.

6 The HORN SPEAKER 9820 Silver Meadow Drive, Dallas, Texas 75217 READER'S PAPER

that were made in these years are in-cluded in the 191$6 Volume 6 manual.

The reconversion of radio manu-facturers to peace time productionwas not easy. Radio plants found thechange over to making home receiverspresenting problems of different typeswhich are more difficult to solve bysome factories. A few plants closedin this period of time due to laborstrikes and problems. This is whysome of the manufacturers are not list-ed in the 19156 manual volume 6.

Volume 6, 19116 manual was publishedalong with a complete book titled,"SERVICE NOTES" on radio record players,automatic changers, wireless units andhome recorders.

Volume FM, not volume 7, was pub-lished in 1947 and consisted of 192pages of F. M. radios and the firsttelevision major wiring diagrams withillustrations.

Volume 8, 1948, volume 9, 1949,volume 10, 1950, MOST -OFTEN -NEEDEDRADIO DIAGRAMS were published in theirrespective years. Volumes 11 throughR-26, 1966 concludes the radio series.

Volume FM really is TV -1 publishedin 191$7 and volume TV -2 1948 the year

of the television consists of 192 pagesTV -3 19119 through TV -29 B & W TV 1970,

C-70 1970, is for color television andthese are currently offered for sale.

Due to the nostalgia craze that issweeping the country, more old radiosand televisions are being hauled intothe shop for repairs, the collectingboom is on. I can thank Morris Beitmanfor all the information, technical as-sistance, and courteous service he hasgiven me in the past years. Althoughthere is only a limited supply of theold radio diagram manuals left'he hasconsented to let them be reprinted,thus enabling our hobby to move ahead.
