hope to beat that promise," he declared, continuing: "As you are well aware, in March of 1950, RCA promised to make available to its domestic receiver licensees complete manufacturing information on the first RCA color receiver when the receiver is placed in commercial production. This information is to include complete manufacturing drawings, bill of material, sources of supply, and inspection of our production setup. RCA will keep that promise. It will invite its licensees to the RCA plant before the commercial re- lease of a color receiver. "I know that you probably want as much information as is available at the earliest possible time in order to meet your respective schedules for getting color receivers to the public. Therefore, it appeared desirable to hold this meeting now — well in advance of our planned production information program — in order that you may have available color receiver information you might not already possess." The engineering position in which the industry finds itself today is the result of many years of hard work in getting a compatible color television system which can be started in an economically sound manner, asserted Mr. Anderson, adding: "We in RCA take pride in our part in this endeavor. Our achievements in color represent hundreds of man- years of work by outstanding electronic engineers, and tens of millions of dollars of investment. We feel that the time and money already spent, and the large amount that will be spent in placing this new service before the public represent a sound investment in insurance, cover- ing the future success of this industr}'. "We strongly believe in the economic and social importance of a compatible system of color television, and we believe that this new service to the public will enable the electronics industry to repeat the success story of black-and-white television." Mr. Anderson pointed out that as precedent for the October 7 meeting on the RCA color television receiver, RCA held a symposium on its tri-color tube in July of this year for licensed tube manufacturers. This, he said, was done as soon as the design was completed on a type for early production, thus providing the tube industry with advanced information shortening the time required to get a satisfactory design of color receiver into pro- duction. Regarding a color television picture tube recently announced by another company, Mr. Anderson said: "RCA has read with some interest that another com- pany — a company which, by the way, went all out for incompatible color and said that compatible color was impractical — has finally come around to adopting RCA's type of color tube with three guns, and using a shadow mask with all the holes. As we read the in- formation released by that company the only difference is that the phosphor dots are on the rear of the face plate instead of on a separate plate directly behind the face plate. "Following RCA's lead in adopting a 15-inch glass envelope, this tube is also enclosed in a 15-inch glass bulb and uses the principle of a face plate sealed in with metal rings. As this tube uses the basic principles of the RCA tri-color tube it should — if it functions satis- factorily — work in the all-electronic compatible color receiver developed by RCA." Color-TV "Kit" For Manufacturers During the symposium, an ofiFer was extended by the RCA Victor Division to supply television set manu- facturers with a limited quantity of developmental kits, containing specially designed tubes and parts required for the RCA compatible color receiver. Although each of more than twenty tubes and com- ponents in the kits is in a developmental stage, they are being offered at this early date to enable the industry to initiate experimental design and production programs for color sets. The contents represent the most advanced results of RCA's developmental work on electronic com- ponents for its basic color receiver. Among items in the kits are a complete develop- mental RCA tri-color picture tube, specially designed receiver tubes, developmental transformers, coils and other associated necessities of a color receiver. With each kit is complete technical and application in- formation. New Microwave Relay (Continued from page 11) snow storms and other atmospheric conditions than the higher frequencies. RCA engineers underscore the importance of this new microwave control system by pointing out the fol- lowing advantages and improvements to be expected as a result of the installation: 1—It is hoped that within a few years the system will pay for itself and result in a saving of many thousands of dollars a year in control line rentals. 2—Records kept on former microwave systems show that fewer signal failures occur over a year than with low quality control lines. This reliability factor is extremely important to RCA operations. 3—Throughout the design of the system heavy an- tenna support structures, modern antenna design and fireproof building construction have been utilized to guard against possible damage from the elements.
