Thirty-two T h INTERNATIONAL PHOTOGRAPHER July, 1934 Television CBS OPERATIONS ENGINEER PRAISES PERFORMANCE OF DON LEE TELEVISION STATIONS "The television pictures on W6XS and W6XAO today were excellent. Congratulations on the fine detail." Such was the signed statement given the Don Lee Television stations by Henry Grossman, eastern divisions operations engineer for the Columbia Broadcasting System, New York, after witnessing a portion of the Para Harry R. Lubcke at the controls of Don Lee television receiver installed in plane of Western Air Express. mount feature, "Tillie and Gus," transmitted over the local television units. Mr. Grossman recently visited Southern California. Grossman's statement carries more than usual weight, according to Harry R. Lubcke, Don Lee television director, in that he was intimately associated with W2XAB, the television station of the Columbia Broadcasting System in New York and has carefully followed eastern television developments. Grossman expressed himself as surprised at the magnitude and scope of the Don Lee television activities and the part taken by interested "lookers" in aiding the advancement of the art. Lubcke has advised that the public of California is invited to share in the work. The enthusiast who builds his equipment and watches the pictures sent out nightly, can assist the work being done by sending in reports on how the signal is received, night by night ; how the image appears, and what irregularities are noted, if any. // is not necessary to have a television receiver to participate in this work. The sound signals of W6XS can be received on 2800 kilocycles (107 meters), on any allwave receiver or short wave adapter, and those of W6XAO on any ultra-high-frequency receiver of the type used by radio amateurs. Voice announcements, concerning the picture being broadcast are made approximately on the hour and half hour. Also, at the close of each schedule, a constant intensity tone is sent out to allow a definite check on the transmissions. The signal sent out when a picture is being transmitted changes in intensity as the scene changes from a close-up to a long shot and from dark to light. It is very interesting to view the image and listen to the sound of the signal at the same time. The sound varies in timbre as well as in intensity from a harsh and gutteral to a clean and sharp tone, depending upon the intensity pattern of the particular scene. After a little practice, it is not difficult to determine when the scene changes or when a character or object moves in a fixed scene ; all have their characteristic variation. However, any change in the constant intensity tone shows a change in the radio wave conditions between the transmitter and the receiver. Listeners' reports as to how this tone changes in intensity from minute to minute, from day to day, and from month to month are very helpful to the Don Lee engineers. Lookers' reports on the appearance of the image, whether clear or blurred, and if fading is noted, as well as with regard to changes in those effects from day to dayare invaluable. Standard report forms for recording these data are available upon request to the television department of the Don Lee Broadcasting System, although any systematically recorded observations are of value. Of particular importance are reports submitted which give the "before and after" effects of a change made at the transmitting stations. Impending changes are announced well in advance over both W6XS and W6XAO at the opening and close of each schedule and are made with the request that listeners and lookers report the results secured both before and after the change. Diagrams and complete instructions for constructing television receiving equipment appeared in the March and April 1934 issues of the International Photographer. WEST COAST BEGINNINGS OF N. R. Here is the beginning of what might be termed "Newsreeling on the West Coast." This valuable still is a shot of Harry Gant, the pioneer cameraman and producer, with his outfit on a journey into the high Sierras where he is going to make a newsreel picture for Thomas A. Edison, his subject being how the Forest Rangers fight fire in the National Forest Reserve. This was in 1912 and Mr. Gant was accompanied on the trip by Forest Ranger Paul Redington, now chief of the United States Forest Service. The shooting was done in Madera county, California, with an Edison camera. In those days the cameraman had to get 'em when he shot 'em, for there were no retakes. Every inch of film had to go to New York and it is believed that this expedition was the first of its kind in the history of motion pictures. Paul Redington shot this still.
