July-August 1929

There wasn’t an awful lot to see when W3XK got a new, improved transmitter in July 1929. More people could view the programming, but consisted mainly of silhouette drawings. No live bodies on camera.

W3XK was one of two Jenkins television stations on the air at the time. Frank Jenkins was spending much of his time in mid-1929 trying to transmit from an airplane (which crashed in August, leaving him with a cut over an eye), demostrating a new kind of TV set, and dealing with two lawsuits.

Meanwhile, in the mountains near Poughkeepsie, a television station signed on. You can read more about W2XBU in this post.

The Buffalo News published a roundup of active and semi-active stations from something called the Science Service. This is from July 3, 1929. Later editions added W2XBU, the increase in power of W2XK and put W9XR on the air, so it must have been current.

All the above stations have been licensed by the Federal Radio commission. A number of others who have previously been broadcasting still have their applications pending.

W6XN had been testing for several months and had its grand opening in August. The available story is unclear about whether visuals were broadcast.

We’ll skip the Jenkins litigation as we look at highlights in TV in July and August 1929. There isn’t much. The Federal Radio Commission was asked to grant some licenses. RCA wanted a second permit, solely for specific experiments which it outlined to reporters. In San Francisco, Philo Farnsworth conducted another demonstration of his system that eliminated swirling discs in studios and television sets. A short version of the W2AX story appeared in one paper on July 26. Both have the wrong call letters.

Television Signals from Plane Goal of Washington Inventor
WASHINGTON, July 1 (AP)—Panoramic views flashed by radio from a speeding airplane to a ground station many miles away is the television goal sought by C. Francis Jenkins, Washington inventor.
Army officers are awaiting with interest experiments soon to be made by Mr. Jenkins with his "aerial eye." If television apparatus can be perfected, as the veteran radio engineer hopes, to send pictures of front line warfare, movements of enemy troops and maps of the battle grounds from scouting planes to general headquarters it will be of great military value.
Jenkins has bought a special plane to be used as a "flying television laboratory" and has been piloting it in practice flights. He plans to be at the controls part of the time when the experiments are made. The "laboratory" is a monoplane of special design, seating four passengers and providing space for television apparatus.
A section of the floor of the cabin will be cut away to serve as a scanning apparatus for the aerial eye. Tests will be made as the plane flies over Washington, views of the ground below being transmitted by radio to Jenkins' new television station north of the city.
The new station is known as W3XK, the same call letters assigned to his old laboratory station in the city. A new 5000-watt transmitter has been installed and two 28-foot towers have been erected. The new station will broadcast a daily program of radio movies In silhouette.

TELEVISION WAVE SOUGHT
WASHINGTON, July 3.—Formal application has been filed with the Federal Radio commission by Station WSVW, Buffalo, operated by the Seneca Vocational school, for authority to construct an experimental television transmitter to be used on 2150 kilocycles with 500 watts power. If the application is granted, it will represent the first opportunity Buffalonians have had to avail themselves of one of the latest developments of the radio art.
According to statements made to the Radio commission by representatives of WSVS, it is the hope of that station eventually to be able to project not only moving pictures in the home, but also the voice and music accompaniment. (Buffalo News)

TELEVISION MOVIES NOW BEING MADE
NEW YORK,--A series of short motion pictures, which are being carried to radio fans by television, now is being produced by Visugraphic Pictures, Inc.
These pictures are being broadcast from station W2XCR, Jersey City, owned and operated by the Jenkins Television Corporation, and may be “tuned in” by radio listeners who have receiving sets equipped for television purposes.
Of Widespread Interest
It is interesting to note that the publicity department of Visugraphic received more than 150 newspaper clippings from every part of the United States and Canada bearing on the new television pictures. This indicates the tremendous news value in the science of broadcasting “movies” by television.
From the commercial advertising point of view, the televisual “movies” offers an unexcelled opportunity to manufacturers to popularize a product in a unique and interest-compelling way. (Calgary Herald)

Compact Drum Scanner Advances Home Television
The latest television receiver for home use has just been demonstrated at the Jenkins television laboratories and is regarded as one of the simplest and most practical forms of receivers yet proposed. It is a development of the original “drum” type receiver invented by C. Francis Jenkins, a pioneer worker in this field and also in motion pictures.
The new televisor replaces the usual awkward scanning disc, measuring a yard in diameter, with the compact and highly efficient scanning drum. The complete televisor is incorporated in a walnut cabinet measuring approximately 18x18x24 inches, as shown in the illustration. The front end of the cabinet contains a recessed opening or shadow box leading to the large magnifying lens through which the radio-movies are viewed, together with three switches and a “framing” crank. The operation of the Jenkins televisor is simplicity itself. The first switch snaps on a neon glow lamp. A short wave radio set, employed in conjunction with the televisor, is tuned in the usual manner, until the characteristic note of the television signal is at maximum in the loud speaker. The second switch turns on the motor and also serves as a simple method of bringing the scanning drum in step with the picture. The crank is turned so as to frame the picture properly from left to right.
The interior mechanism of the televisor is compact, simple and rugged. The earlier laboratory set-up has been reduced to commercial production equipment for home use. The synchronous motor and scanning drum are mounted vertically and supported by a stanch angle-iron framework.
A special form of distributor serves to flash the four neon lamp plates in succession, illuminating the four quartets of the scanning drum in four successive revolutions. The operation is exceedingly quiet. The framing crank serves to turn the motor and its scanning drum slightly, so as to bring the picture into step with the scanned image. The scanning drum holes are viewed through the magnifying lens, giving an apparent screen size of about six inches square, or sufficient for the simultaneous entertainment of six to eight persons.
As for the nature of the entertainment, only the simplest subjects are being broadcast at this time. Instead of attempting very crude half-tone pictures the engineers are endeavoring to transmit and receive silhouette or black-and-white movies with a fair degree of accuracy. The demonstration of a thrilling boxing contest in silhouette form can be readily followed on the televisor screen and if anything, is so unique as to be perhaps more fascinating than if it were shown to the usual full tone. Titles are included in the television pictures. (New York Herald Tribune)

Bound Brook Likely to be Site Of Television Plant for RCA
Two developments in radio in the metropolitan area are awaiting decisions by the Federal Radio Commission, according to a representative of the Radio Corporation of America. An application has been filed for an experimental television station license for a transmitter to be located at Bound Brook, N. J., where Station WJZ’s transmitting plant is located. The application requests that the thirty kilowatt image broadcaster be permitted to operate on the frequency band of 2,850-2,950 kilocycles, equivalent to 105 to 101 meters.
No definite information relative to the plans of this television outfit will be released, according to the RCA representative, until the license is issued. He declined to say whether this television plant would supplant the one now in operation at 411 Fifth avenue, or whether its entry into the ether lanes would mark the beginning of regular television service for the home.

Movies in Home by Radio Object of New Invention
WASHINGTON, July 14.—(Universal News Service)—A 23-year California inventor, E. L. Peterson of Los Angeles, has obtained patent rights on a new and revolutionary new television principal, it was revealed here today.
The Peterson invention solves the present great problem of synchronization between the sender and the receiver of visional broadcasting, according to the inventor and his attorney, Judge Jerome Lyman Richardson of Riverside, Cal., who claimed it will make radio-movies as available as the present vocal radio.
Judge Richardson went to New York today to confer with bidders for the patent rights and for production of the set. He declined to discuss technical details of the new invention, but said:
“It embodies a new and simplified principle, which entirely masters the question of synchronization between the broadcasting and receiving points, heretofore the great problem of televison. All synchronization obstacles of the past have been eliminated and the Peterson invention will make it possible for the average person to sit down in his home, turn a dial and receive the picture broadcast with the aid of no more technical knowledge than is necessary for the operation of the radio.”
The invention is known as ray-o-vision and a corporation has been formed under the laws of California to handle it. Peterson his attorney plan to leave shortly for Europe with a view to interesting foreign operators. Pittsburgh Post-Gazette, July 15)

WOKO BROADCASTING TELEVISION PROGRAMS
Visual broadcasting, known popularly as television, is now part of the daily radio program of Station WOKO, located on the top of Mount Beacon, near Poughkeepsie, N. Y., according to the Hudson Valley Broadcasting Company, its operators. The images are sent out each after between 2 and 3 o’clock, Easter Daylight Time, on a wavelength of about 145 eters. The call letters are W-2XBU. Subjects used for the visual programs at present are persons, placards, letters and small objects. While images transmitters are said to be “not perfect,” it is expected that experiments will find their reception an interesting diversion and an aid in carrying on television work with home-made receiving equipment.
The apparatus required to intercept the visual programs is a shortwave receiving set equipped with resistance-type audio amplifier, scanning disk, driving motor and neon tube. (New York Times)

WEDNESDAY, JULY 17, 1929
TO TEST TELEVISION OUTSIDE OF CITIES A thorough study of the possibility of reliable television service for large suburban and rural areas will be made at Bound Brook, N. J., if the Federal Radio Commission grants an application now before it for a 30-kilowatt image transmitter, according to Dr. A. N. Goldsmith, chief broadcasting engineer of the Radio Corporation of America, who will direct the tests. The wave length proposed is 101 to 105 meters, or 2,950-2,850 kilocycles. It is expected that a comparatively short time will be required to prepare for the tests.
“Our plan,” said Dr. Goldsmith, “is to determine the limitations of visual broadcasts outside of cities just as we are now studying such problems within cities. We hope to ascertain the general transmission characteristics of rural television, how such signals will be affected by static and fading, and the power required for coverage of definite areas.
“Television signals have a less useful range than that obtained with a transmitter sending out audible programs. The short wave lengths assigned for television work are more highly absorbed between the transmitter and the receiver. The zone of fading on short waves is nearer the sending station, say within 100 to 150 miles. Television also requires very critical and difficult methods of transmission and reception, therefore we need unusually perfect signals for high quality service. All these characteristics and limitations are to be carefully studied, so the tests will be entirely experimental, leading later perhaps to a study of television over greater distances.
Dr. Goldsmith said the 30-kilowatt image broadcaster probably would give adequate image service in an area of 500 to 1,000 square miles. (New York Times)

TELEVISION BROADCASTING IS INAUGURATED ON NIGHTLY WASHINGTON PROGRAMS
By KENNETH G. CRAWFORD
(United Press Staff Correspondent.)
WASHINGTON, July 22.—(UP)—Picture broadcasting was placed on a permanent nightly basis for the first time here tonight with the formal opening of a new studio by C. Francis Jenkins, pioneer in the development of television and president of the Jenkins Television company.
For more than a year the inventor has been broadcasting tri-weekly programs from a 50-watt station in his downtown studio and has gained an audience estimated at 20,000, most of its members amateur radio operators.
To serve this audience better and recruit new members, Jenkins established his new station in a converted farm house five miles north of the District of Columbia line. He was recently granted permission by the Federal Radio Commission to operate a station on a wave length of 2,900 kilocycles.
With this more powerful station, he hopes to send pictures regularly as far west as the Pacific coast and as far south as Porto Rico. Even from his old station a few amateurs were able to pick up his programs occasionally from those distances.
Opens New Studio.
Jenkins announced with the opening of the new studio that he will attempt to broadcast views of the national capital radioed from his airplane to the ground station. This will be done with the "aerial eye," on which the inventor has been experimenting almost every day for several years.
The inventor pilots his own plane. His first machine was damaged recently in a forced landing and he is now equipping a new one for the forthcoming tests of the panorama broadcasting device. The mechanical "eye" of the equipment will peer through a hole in the bottom of the ship.
The views it picks up will be sent to the new broadcasting station and retransmitted to the television audience. In order to reach remote receiving stations two 130-foot antenna towers have been erected near the country studio.
The opening program of the new station was a one-hour motion picture which Jenkins prefaced with a brief talk. Later he will broadcast scenes enacted by living images, but the room from which this is to be done is not yet completely equipped.
Jenkins has found that television fans prefer to see living objects rather than motion pictures. The change in power and frequency in the new station has made it necessary for members of Jenkins’ audience to reconstruct their sets somewhat. Most of the amateurs who receive television programs have assembled their own sets from parts made at home, or supplied by the Jenkins Company, the inventor said.
The same equipment required to pick up sound waves is used to receive television waves, but this must be supplements with the picture projection device.
The picture as it comes in is about six inches square and shows on an illuminated screen in black and white.
"We know how to broadcast colors," Jenkins said, "but it isn't practical because it would require too many wave lengths. We would ruin the air for everyone else by attempting it."
Jenkins will not use all the power granted by the radio commission in his initial programs, but plans to utilize it all eventually.

Entire Show Is Broadcast By Television
Washington, D. C., July 31.—Television has turned the corner, according to eminent radio authorities after the encouraging results from the Jenkins television broadcast over station W2AX were made known recently.
For the first time in history, a complete picture story was televised. This "television drama" was on the air one hour. Reports of its satisfactory reception were received from points as far west as Chicago, and as far north as Lexington, Mass. Station attendants expect several days to elapse before all reports are received.
The program was the first of a series to be sent out regularly from 8 to 9 p.m., Eastern Standard Time, over the new power transmitter recently installed about five miles north of Washington, D. C. The series was inaugurated in the presence of radio commission officials.
Dr. Jenkins shared the enthusiasm of friends, radio engineers and television fans who witnessed or took part in this epoch-making event. From now on the public will take a keen interest in these broadcasts, and a big impetus will be given to the further development of television which will usher in a new era of opportunity for radio men and the general public.

'Talkies' in Home Promise of New Television Device
Philo T. Farnsworth, inventor of a new television device, which he claims will soon permit owner of radio sets to receive motion "talkie" pictures in their homes, demonstrated his invention last night. A group of scientists witnessed the tests.
Photographs, the silhouettes of moving fingers and the curling upwards cigarette smoke were transmitted in his Green street laboratories, from one room to a receiving set in another, and were visible on a screen.
New Method Used
The scientists who witnessed the exhibition were members of the Board of Directors of the California Research Group of Science of Vision—Prof. R. S. Minor, University of California; Dr. T. A. Brombach, Dr. Van Simonton, Dr. J. R. Morris, Dr. Leland Carter and Al Reinke, lecturer at the University of California.
Professor Minor declared that the demonstration was "most interesting.” He said he was particularly impressed with the new method of “scanning”. The Farnsworth device does not use a "scanning wheel" or scanning disk, as is used in other television system. The picture is "torn down” at the transmitting end and "built up" at the receiving end by electricity.
Farnsworth stated that with his device families possessing radio sets will reasonably soon be able to hear and see in their living rooms musical comedies as they are being acted and sung in some distant city, that they will be able to watch some spectacular play occurring in a football stadium, hear the impact of men's bodies as they buck the line, see the fumbles and the passes and the roaring approval of the stadium crowds.
He promises that pictures of events taken in the sunlight will soon be transmitted clearly by his system.
The astonishing new instrument invented by Farnsworth is not a bulky affair. In a cabinet of ordinary size, it resembles the average home radio receiving set. Instead of a loud speaker there is an attachment on top of the cabinet with a round orifice for the "vision field."
He says that the experiments so far made have convinced him and his associates that the device can be placed in a still smaller cabinet and that plans are under way to put it into practical use on a large scale. (San Francisco Examiner)



TUESDAY, AUGUST 20, 1929
KGO’s program tonight will be a memorable event; impressive from the number of dignitaries to be presented, absorbing from a dra¬matic and musical standpoint and spectacular for those who will witness the broadcast which will originate in the San Francisco Civic auditorium in conjunction with the Sixth Annual Pacific Radio show. KGO will be on the air from 7 to 11 o’clock.
For its night at the radio show KGO has delayed the opening of its 40,000-watt short wave station W6XN. State and civic officials have been invited to participate in this opening which will feature artists of many foreign countries wearing native costumes. This program will be rebroadcast by the New York stations of the General Electric and it is expected that a score of foreign stations also will relay the W6XN transmission.
Preceding the W6XN inaugura¬tion there will be half-hour program by the Rembrandt Trio. the Melodettes, and the Olympians. At 8:30 those celebrated musical no¬mads, the Pilgrims, who have been traversing the ether lanes for nearly four years, will make their appearance, with August Hinrichs directing. Vocal numbers will be sung by Eva Gruninger Atkinson, contralto, Grace LePage, soprano, and the Olympians. (Santa Ana Daily Register)

Chicago Station Give Television License
A television broadcasting license has been granted to WENR. The Chicago station has been allocated the visual broadcasting channel ranging from 2,850 to 2.950 kilocycles by the radio commission for television transmission on regular schedule with 5,000 watts power. There are now approximately a dozen stations licensed to broadcast television but all are on an experimental basis. (Chicago Triune

TELEVISION SETS NOW BEING MADE BY JENKINS CORPORATION
With the recent development of a novel combination scanning drum and selector shutter disk by its engineering staff, resulting in a simpler, more economical, and far more practical scanning system, the Jenkins Television Corporation of Jersey City, N. J., now announces the mass production of television apparatus.
“Although we have been in production on experimental television equipment for six months past,” states James W. Garside, President of the Jenkins Television Corporation, “we have withheld mass production of market models until we could be positive of our grounds. Our earlier models were too elaborate and costly for use in the average home, while the results left much to be desired. Therefore, our production until now consisted of sample televisors for use in checking up the efficiency of our television transmitters at Jersey City and Washington, under typical receiving conditions.
48-Line Reception.
“With out [our] latest development, we have evolved a remarkably simple, inexpensive, and highly practical televisor, which can be readily manufactured at a reasonable cost. The new Jenkins televisor will permit of receiving either plain black and-pink radio movies or full half tone pictures, with good detail and illumination within the limitations of our present 48-line system. Should we find it advisable to go to 60 or more lines, based on our present experiments and developments, the Jenkins televisors can be readily changed over to accommodate additional lines and finer detail.
“All in all, I am satisfied we now have a practical televisor with which we can inaugurate everyday television,” concludes Mr. Garside. (Brooklyn Daily Eagle)

Motion Picture Are Broadcast
Distinct Progress Being Made in Television Studios at Pittsburgh
[By ROBERT D. HEINL]
Distinctive progress is being made in the broadcasting of motion pictures at the Westinghouse plant at Pittsburgh. Motion and still pictures are being sent daily from the television studio in Homestead works, thence by wire four miles to the KDKA transmitting station and broadcast from there to the Farm, as the short wave receiving station is known about six miles northeast.
Ordinary moving picture films are used and such subjects being shown a Krazy Kat and Pathe current news events. It was explained that motion pictures were chosen because they are more difficult to than actual objects. However, at the Homestead television studios, scanning devices are also available for the broadcasting of living subjects. A television studio is indeed a curious looking place and with its bright lights not unlike a moving picture studio.
Formerly because of the makeshift apparatus, an observer was constantly reminded of the experimental nature of television, but there is little of this in evidence at Pittsburg. The transmitting apparatus is of a substantial character and finished in appearance. The reels whirl in the same businesslike way as for a regular motion picture and with countless operators the scene presented in the television studio is similar to one so frequently seen in the projection booth of an ordinary movie theater.
Looks Like Going Concern
Likewise there is the air of a going concern at the receiving end. Not a lot of loose junk wired together but the apparatus compactly assembled on a table and resembling a camera outfit about the size a professional photographer uses. Also a thing one rarely sees in an experimental laboratory—the floor was neatly swept. Viewing a television picture recalls vividly the way we used to look at old time motion pictures in a kinetoscope, excepting that here in a darkened room sees the picture by peering into a long cylinder sometimes standing as far as five feet back to get the right focus.
The moving pictures being broadcast at Pittsburgh are as yet small, about three by four inches in size but larger than the Bell telephone pictures being sent over wires in color which are only as big as a postage stamp. In both the Westinghouse and the Bell demonstrations, however, the details of the pictures are surprisingly sharp and distinct.
“If we make as much improvement in the next six months in broadcasting motion pictures as we have in the past six,” a Westinghouse official remarked, “we will really be able to report progress. As soon as we get one thing lacked we go after the next.”
Let not the reader gather from this that any definite time has been set when the last thing will be “licked” or when we may expect to receive regular television broadcasts into our homes. It may be just around the corner and again it may be years. At the moment research is being carried on along two lines. The first is perfecting quality of the transmitted picture and the second is the effort being made by radio manufacturers to design a receiver or an attachment to go on radio sets, capable of receiving broadcast pictures and selling at a price within reach of the general public. Quite tantalizing at Westinghouse is a peep at the new 100,000 watt tubes, said to be the world’s largest, which are in the making for the new KDKA and KYW stations, without being permitted to go into details regarding their construction or possibilities. They look to be about eight feet in length and are the first to have water-colored grids. So intricate is the process of manufacture that, though a new tube is started every week, the net result is only about two completed tubes a month. So it may be some time before the required six are completed for the new KYW station at Chicago and 12 for the new KDKA station near Pittsburgh. Although the Westinghouse people are as silent as clams regarding these great new tubes, it is believed when the facts are known about them they may prove a sensation in the radio world. Rumor hath it that instead of 100,000 watts, tests have shown that they are capable of 150,000 watts power (Tulsa World)
