Report: Radiophone Broadcast of Dempsey-Carpentier Fight on July 2, 1921 (the exhibits/attachments referenced in the report were not included).


JULY 2, 1921


Radiophone Broadcast of Dempsey-Carpentier Fight on July 2, 1921

          The unprecedented undertaking of broadcasting by radiophone a voice description of the Dempsey-Carpentier contest for the championship of the world, met with a success far beyond expectations.
          The description, broadcasted during the boxing match on the afternoon of July 2nd, was made audible in theatres, halls, auditoriums and in homes and aboard ships to probably the largest audience in history. The area covered was about 125,000 square miles (200 mile radius) and the reports received to date indicate that more than 300,000 persons heard the voice as it was transmitted from the Hoboken station of the Radio Corporation of America.
          Preparations were begun early in April, when the National Amateur Wireless Association (an adjunct of The Wireless Press) made a firm arrangement with Tex Rickard to take over exclusively the technical arrangements. It may be of interest to note here that when the idea was broadly presented by the Rickard interests to various persons and firms of some prominence in radio, they were practically united in the opinion that the undertaking was an impracticable one. We, on the other hand, were certain of success from the start, in contradiction to the opinion expressed by Hiram Percy Maxim of the American Radio Relay League, who was on record in writing with the statement that the greatest possible range would be 100 miles and the voice could be heard only in the headphones, and could not be made audible by loud speaking devices. The League also turned the proposition down officially, when it was presented to them by recommendation of Commander Patterson, Dr. Parker, Mr. Gawler and others. The Westinghouse Company also had the opportunity, but replied with a business proposition of selling receiving apparatus. There were others, but the point is, we were the only ones willing to undertake operation of the whole scheme and put it through to a successful conclusion.
          Several months were occupied with preliminary organization of the details of the plan, which are clearly outlined in the circular attached (Exhibit A) which was mailed to 7,500 amateurs on June 10th. At that time, the conference period was ended and the American Committee for Devastated France and the Navy Club, as participants in the box office receipts, had started representatives on the road in search for theatres and halls in which the radiophone returns could be received.
          A formal application blank (attached as Exhibit B) was enclosed with the circular, and in this way the qualifications of the amateurs who offered their services were determined. In an undertaking of this kind it was necessary to secure amateurs of the highest type who were skilled in reception, and it was found that the replies to the questions of Exhibit B gave us the necessary information to determine to a very close degree the qualifications and ability of the volunteers. The selection of personnel and their assignments was left to Mr. J. O. Smith, whose knowledge of amateur conditions proved invaluable in perfecting the arrangements for the receiving end of the program.
          Mr. Smith's report covering the operating part of the radiophone broadcasting on July 2nd discloses the following features of interest: On June 22nd, the latest date for the acceptance of theatres or halls where the returns were to be handled, Mr. Julius Hopp, theatre representative of the American Committee for Devastated France and the Navy Club, reported that halls and theatres had been secured at forty-seven cities outside of greater New York, with eleven theatres, halls and auditoriums inside of greater New York, or a total of fifty-eight.
          In the absence of any definite information as to the daylight overland range of the radiophone set to be used at Hoboken it was decided to keep within a two hundred mile radius, and in accordance with this decision theatres, halls and auditoriums were secured at the following places, outside of greater New York.

          As the returns from the circular and application began to come in it was evident that the amateurs were responding in a wholehearted manner to the appeal for assistance, even though the reception on 1600 meters was in most cases an unknown quantity. It was quite common to find remarks on the application, to the effect that they had no equipment for receiving on 1600 meters. And in reply to the question as to what stations were heard on that wavelength, approximately fifty percent of the replies, which numbered up to the hundreds, stated that none were heard, as the applicants never listened on that wavelength. The amateurs seemed very well equipped with the most efficient apparatus for reception on wavelengths below 600 meters but above that wavelength they had only make-shift apparatus. The comparatively limited number of amateurs who offered their services for the reception on 1600 meters on July 2nd was undoubtedly due to a large extent to the lack of proper equipment for reception on this wavelength, and to the fact that the matter of being responsible to large gatherings of people scared them.
          It also developed that very few amateurs possessed proper loud speaking equipment. The lack of proper apparatus of this type was one of the great problems of the undertaking. Even the best apparatus of this type which could be secured from dealers and manufacturers distorted the voice when much amplification was used.
          The sum and substance of the whole matter of reception by amateurs seems to be that they have for so long played around on 200 meter wavelengths in an irresponsible way, that when it comes to a proposition of handling 1600 meter reception for audiences running in some cases up into the thousands, and where perfect reception and amplification was necessary, the amateurs were inclined to have "cold feet".
          But now there is not a single doubt that the amateur radio operators in this part of the country have now awakened to the fact that there is a place in radio for amateurs outside of the little 200 meter undertakings. Whereas the amateur has heretofore been responsible only for himself and, as a result, has carried on in an irresponsible way, on a hit or miss plan, is believed that the undertaking as a whole has done more to educate the amateurs of the country to the great usefulness of radio in a big way than has been true of any undertaking ever before handled in the realm of amateur radio.
          The broadcasting of July 2nd, viewed solely from an amateur's standpoint, was without question, the biggest thing ever done since amateur radio wore short pants. It has created an untold amount of interest in the National Amateur Wireless Association and the Radio Corporation of America. Letter after letter has been received stating that the writers were glad to see that at last someone had done some-thing worth while, and had given amateur radio operators an opportunity to participate in an undertaking which really meant something, and which gave the amateur an opportunity to participate in something man's-sized.
          We have been urged repeatedly in these letters, to keep the idea going, and not let it sleep. Suggestions as to how this could be done have been included. The correspondence which has followed the July 2nd broadcasting shows convincingly that the writers of these letters expressed sincere thoughts and wishes in the suggestions.
          While this report is not made from an engineering standpoint, a little discussion of some of the technical features involved from the beginning of the preliminary tests to the finish of the broadcasting on July 2nd may be of interest.
          A great many of applications for participation from the amateurs contained some reference to preliminary tests. Every amateur who signed an application for participation in the reception received an immediate reply to his letter and this reply contained a schedule of preliminary tests which had previously been laid out for the Hoboken transmitter.
          The first preliminary test was held between 7 and 9 p.m. Friday, June 24th. The antenna current was then only around 4 amperes. Mr. W. J. Purcell, who had been detailed from the General Electric Company to supervise the operation of the radiophone set, used good judgment and held down the output of the set until he got his bearings in the new location. The results of the first night's tests were, of course, discouraging in a way, although not unexpected. It was looked upon as more or less a preliminary test of the transmitter, for up to that time no one was sure that the set would work at all.
          On the following day, Saturday, June 25th, a daylight test was made between 2 and 4 p.m. under practically the same conditions which might be expected on the afternoon of July 2nd during the time of the fight. The antenna current in this case was approximately 8 amperes and the results were somewhat better than the preceding evening.
          On Sunday, the 26th, the T antenna was enlarged and the natural period increased from approximately 450 meters to 750 meters. The flat top, which was at first 250 feet long, was increased to 450 feet. The average height of the antenna was 250 feet. It was readily apparent that this added radiating surface had increased the effective range of the set, for, with increased antenna current, reports began to come in from points not previously heard from, following the test on the evening of Monday, June 27th. It was determined at this time that the set was not modulating efficiently and a thorough investigation was made. It was found that the condenser in shunt to the plate reactance coil was short-circuited, in view of which it is a wonder that the set modulated at all on the previous tests. A new condenser was supplied and an improvement was noted in the modulation. It was also found that the filament heating transformer was not supplying adequate voltage to the tubes and it was accordingly brought over to 326 Broadway and changes made in its windings so that the proper voltage for the tubes was provided.
          On Thursday night, June 30th, the antenna current had been increased until it was approximately 12 amperes, with an increase of 1 1/2 amperes on modulation, and, beginning with this test, very encouraging reports began to come in. Distant stations which had before that time reported very weak signals, or no signals at all, then began reporting fair speech or speech that was entirely satisfactory.
          On the night of Friday, July 1st, so many reports from amateurs had been received that they were used as a substance of speech for the final test and approximately 100 amateurs were called through the air, by name and call letters, and thanked for their interest in advising us as to the character of the speech from WJY station. On this night, in addition to the regular publicity for the Radio Corporation, General Electric Company and the N. A. W. A., several special features were added in the way of addressing gatherings, notices of which had been given us, such as the Police and Fire Departments of several cities, and social affairs of volunteer Fire Departments. In these cases enterprising amateurs had set up receiving sets and the talk by radiophone to the members of these organizations and their guests became the star feature of the entertainment at each of these places. In every case we were advised by telegraph or letter on the following morning that the speech had been received clearly and distinctly, and so appreciative were the officers of one of these organizations that the matter of appreciation took the form of good smoking material for the personnel operating the Hoboken transmitter.
          This matter of calling amateurs and individuals through the air started a land-slide which resulted on Friday afternoon and Friday night in a deluge of reports from amateurs and organizations within the entire range that it was intended to cover on Saturday afternoon during the fight. Mr. White, at 326 Broadway, answered approximately fifty telephone calls and at Hoboken, Mr. Hayes, in order to save time, took a place at the Lackawanna telephone switchboard in the Pullman Building and made notes of the reports. Neither Mr. White nor Mr. Hayes was able to keep up with the incoming stream of reports that amateurs were trying to make. The enormous good-will engendered came home strongly on this occasion, for the enthusiasm was costly to the amateurs who were paying long-distance telephone tolls to express their appreciation.
          It is undoubtedly a fact that on the night of July 1st interest among the radio fraternity in the performance of the Hoboken transmitter was running at unprecedented height. The antenna current at this time was approximately 14 amperes with an increase of another 2 amperes on modulation. The speech was reported as being strong over the entire range it was expected to cover the following day.
          It seemed then that if the same weather conditions held over Saturday and the set operated as well, that our undertaking was bound be successful. Saturday morning brought another deluge of reports and all indicated that the set was working at 100 percent efficiency as to strength of signals and clearness of speech over the range of 200 miles claimed for it.
          On Saturday, July 2nd, it was intended to put in fifteen to twenty minutes before 1 p.m. tuning up the set, but the unexpected early start of the preliminary bouts made it necessary to throw on the switch and start talking, irrespective of the lack of time in which to look over the set or make any adjustments, and it is a matter of great satisfaction to know that the set operated perfectly throughout the description of all the preliminary bouts and the big fight itself.
          The antenna current on Saturday was 14 amperes with an approximate increase of 2 amperes on modulation. The retransmission at Hoboken was never more than a minute behind the actual events at the ringside.
          Mr. Sheehey of the Broad street office, who took Mr. White's ringside dictation on the typewriter, was able to keep up with it closely, and these bulletins were made available for retransmission over the radiophone set within a minute after they were received.
          Retransmission at Hoboken was timed so that each round was described in three minute periods with one minute intervals allowed between the rounds.
          Reports containing remarks of listeners from a number of scattered points throughout the district covered by the voice transmission tell the story eloquently. The complete success is clearly indicated in the following extracts selected from several hundred received:

Mr. Kulik enclosed with his letter a clipping from a local paper which stated, among other things, that the broadcasting was done through the courtesy of the Radio Corporation of America.
Fordham, N. Y. Mr. B. D. Heller writes as follows: "The broadcasting of the fight was simply wonderful. Even the gong sounded plainly as could be. The broadcasting was received on a little, old loose coupler, silicon detector and single phone I had stored away for years and only got it out to get my boy started in wireless during vacation. Never expected to hear a 'world crier' by radiophone. You must have been heard over thousands of miles. Some 'Town Crier' I'll say! Almost thought I was in the front row at the ringside when you counted Carpentier out. It was realistic and impressive to the highest degree.
Brooklyn, N. Y. Harry B. Fischer, 269 Lincoln Avenue, writes as follows: "With a 2 step amplifier connected to a small size loose coupler and with the above inserted in two megaphones the voice could be heard clearly and distinctly through three rooms of our apartment, where fifteen persons assembled."
New York City. Mrs. H. W. McMann of 380 Riverside Drive writes that her son was participating in the reception of the returns at one of the local theatres and that as the afternoon wore on and she began thinking about the fight she got to the point where she could no longer restrain herself and listened in on her son's receiving set. She then describes in detail the reception of the fight and pronounces it so remarkable as to be almost unbelievable.
Bayonne, N. J. W. A. MacMaster writes that the audience at his home ranged in age from eleven to forty-five years and everyone was intensely interested. He reports that they all agreed that the case of the wireless amateur took a great stride forward last Saturday afternoon. He has forwarded us a resolution, signed by all of those who listened to the returns at his home, requesting that a similar detailed description by radiophone be made of the 1921 World's Series baseball games.
Hillside, N. J. Miss Mary M. Maurer writes that her young brother had some difficulty at first in tuning in the voice and that as she is opposed to prize fighting generally she at first refused to help him, but after hearing a few words come through she got so excited she forgot all about her prejudice against prize fighting. With the set she entertained her entire family, including her grandmother.
Montclair, N. J. E. L. Versfelt states that his antenna consisted of a single wire hidden in the moulding of a second story room. Total length of wire twenty-eight feet. The voice was audible all over the house.
Allentown, Pa. N. W. Meitzler states that he made every effort to secure a hall but was unsuccessful. He attempted to borrow a megaphone from a local music store, but as Saturday was their busy day he was unsuccessful. He finally rigged up a megaphone in connection with one Baldwin head telephone and in this way entertained a large gathering at his home.
U. S. "Acropolis" Captain C. H. Batchelder radioed us via East Hampton, L. I., thanking us for the fight reports received 400 miles at sea. He states that every word was clearly understood on board the Acropolis.

Stonington, Conn. Benjamin F. Cutler writes that voice description of the preliminaries and the big fight and the ringing of the gong between rounds was clearly heard. Says that news of the fight by radiophone was just as good as being at the ringside. Wants more of it.
Lynbrook, L. I. J. J. Guarino reports the broadcasting as being the loudest and clearest radiophone talk ever heard by him.
Butler, N. J. Martin Petterson knew nothing about the voice broadcasting when he began tuning set and accidentally stumbled across our voice transmission. Wishes to congratulate us on the great success of the radiophone as demonstrated to the world at large last Saturday. Wants to know if we are going to make a regular thing of it.

Bronx, N. Y. G. R. Herbert is so enthusiastic over the voice broadcasting of last Saturday that he had the copy he made of the voice broadcasting framed and hung on the wall of his radio station.
Trenton, N. J. F. H. Schoenthaler reports the voice heard all over a room by means of a Baldwin phone attached to a megaphone on one tube only. In a postscript to his letter he asks: "What's next?".
Frankfort, Philadelphia, Pa. S. J. Thackery, using a 2 step amplifier and regular phonograph horn, found the voice easily audible 100 feet from the receiving set. Fifty persons listened to the voice broadcasting at his station.
New York City. F. S. Gostenhoferer writes as follows: "While I am one of many thousands of 'rank outsiders' in wireless who listen in to what the World is saying, doing no sending, I nevertheless feel that I owe you many thanks for the very able manner in which the voice broadcasting of the several fights today, including that between Dempsey and Carpentier was handled. Several people here enjoyed the fights as they progressed. You have not only rendered a great public service but demonstrated once again the remarkable possibilities of the radiophone both at present and for the future."
Brooklyn, N. Y. Fred Fitz Gerald received the entire broadcasting of the preliminaries and the big fight and sent us a copy of the broadcasted matter to prove it.
U. S. Delambre (at Dock at Brooklyn, N. Y.) Operator states that he used only a marconi crystal receiver and that the voice was by far the best he has ever heard on that type of receiver. Entertained the officers of the vessel and the crew during the broadcasting of the fight.
Hackensack, N. J. Charles Winters writes that his son Peter, fifteen years old, has erected a home-made wireless outfit in the back yard of his house. States that the boy constructed the whole apparatus out of waste wood and pieces of wire and that if we had an opportunity to look the outfit over we would probably laugh. On the night of July 1st he ran in to his father and exclaimed. 'Father, I hear somebody SPEAKING!' "At first I did not believe him, but was easily convinced as I heard the voice myself. Needless to say the young man was greatly excited. We enjoyed the speech and music very much and it was as distinct as if it were in the same room." He further says that when the amateurish, incomplete wireless outfit of a school boy could receive these messages so distinctly it certainly seems to open up an immense future possibility for the radiophone.
Brooklyn, N. Y. Malcolm L. Homan used one head telephone and a phonograph horn and by this means several people were entertained. Mr. Homan states that he hopes that the undertaking of July 2nd was only a start and that before long there will be a general public service reporting important things such as baseball games, tennis matches, etc.
New York City. Edwin Frankerstein, Jr., had six guests who listened on a crystal detector and were amazed at the clearness and strength of the speech.

South River, N. J. Charles H. Dugan writes: "Through courtesy of two young men, Fred Cost and his brother John, I was able to receive first hand information as to the fistic encounter recently held in Jersey City. The boys were generous and permitted a good size crowd to gather in a shed at the rear of their home, while the less fortunate clung about the windows and doorway to have the tidings relayed to them by those at the instruments, using stage whispers, to pass the information along to those outside. The voice of the person at Jersey City who was sending out the news was quite as audible and distinct as one might wish for, even the clang of the gong at the ringside could be distinctly heard. One elderly woman was so wrought up as the news began coming in that she said even if she was over 70 years old she was sorry that she didn't have five dollars bet on the outcome of the fight. I'm glad she did not, as the excitement for her was aplenty without it."

Asbury Park, N. J. W. Harold Warren writes as follows: "My compliments to you on your excellent work during the Dempsey-Carpentier bout. Owing to your perfect enunciation, your clear and vivid description and your calm and measured speech under such exciting surroundings, I was able to obtain perfect reception in a roller chair on the Asbury Park Boardwalk, using a new type of loop, a detector, and a two-step amplifier, and signals were equally as good whether the chair was in motion or at rest. The cheering of the crowd could be distinguished and each sound of the gong seemed as though it were but a few feet from the roller chair instead of in Jersey City, notwithstanding the fact that we were but 100 feet from the noise of the breaking surf. I have sent a check for $13.00 and photo to the N. A. W. A. Again congratulating you."

He states that from an experimental standpoint the event will go down in history as a most wonderful accomplishment. His letter concludes as follows: "Why was brother 2ZL so nervous on Friday night when he said to Mrs. 2ZL over the air that he would not be home until late? Be brave brother, be brave! Maybe some day Mrs. 2ZL will understand the feeling that runs through our etherized systems. If brother 2ZL wants to aid me a little please ask him to give me data on a circuit to use two 50 watt tubes for a Heising circuit or the best circuit he can give me for one oscillator and one modulator.

Hoyd reports that he entertained several friends and is very enthusiastic "over what amateurs have done, are doing and will do." He asks for one of the reception certificates, which he "will always treasure."
Long Island City, N. Y. Among the reports from those who supervised theatre installations is one from William F. Diehl, assigned to the Queensboro A. C., from which these extracts are taken as a specimen of the showmanship features of the program. He says:
      "The broadcast was received with remarkable intensity and clarity. The output was transferred to a Western Electric loud speaker which made the voice easy to understand in any part of the arena, which by the way seats 8,000 people. It might interest you to know that not a single interruption of the voice was noted during the entire broadcast. Every word was clear and distinct. Not one person could be discovered in the crowd who had ever witnessed a demonstration of radio telephony before and one could hear a pin drop it was so quiet during the performance."

          The quotations from the foregoing are from scattered letters out of our collection of hundreds. They are representative, but by no means inclusive. The interest of the amateur fraternity and others has been so great that it is impossible to tell how many really listened in, for thousands of stations did not report.
          As nearly as can be determined from the reports, approximately 300,000 persons listened to the broadcasting of the preliminaries and the big fight.
          There is one thought which runs through a large proportion of the letters received to the effect that this method of voice broadcasting big events is something which should not be allowed to die. The idea is novel and the method has proved to be so entire satisfactory to all listeners, even at points double the distance beyond the claimed range of the transmitter, that we are being urged by hundreds of people interested in radio to continue the practice. All sorts of suggestions are made, including baseball games, speeches by the President and other noted men, symphony concerts, grand opera, tennis championship matches, golf matches and other events in which there is large public interest.
          It should not be overlooked that out of the hundreds of letters received here a fair proportion of them include money to be turned over in aid of the general cause of the American Committee for Devastated France and the Navy Club, showing that while the event was enjoyed and participated in by hundreds in a scientific way they also kept sight of the main object of the undertaking -- aid of a charitable cause.
          This initial step should not be recorded as a one-man undertaking. Special credit should be given to J. O. Smith for his capable handling of the receiving program and the voice re-transmission from Hoboken; to W. J. Purcell for his re-arrangement of the transmitting equipment and perfection of its operation; to George W. Hayes for general supervision of the Hoboken installation and to H. L. Welker for absorbing a great amount of detail work and essential correspondence.
          The radiophone as an amusement devise proved its practicality beyond any expectations. Commercially, it can be made very remunerative, and as a publicity device it should be rated far ahead of any other form of good-will building that could to used to reach the radio fraternity.
          It has put the N. A. W. A. high on the wave of popularity and proved the superiority of Radio Corporation transmitters, stimulated the sales of radiotrons and opened up an entirely new field for amateur reception on higher wavelengths.
          Supplemented by similar exhibitions of great public interest, phone broadcasting will invite the lay public in and develop the field. Augmented by the proposed chain of C. W. stations across the continent operated by the N. A. W. A., the Radio Corporation interests can dominate the amateur field.
