NAB reports (Jan-Dec 1940)

At the entrance gate each picnicker received a list of the forty prizes for the drawings and tickets for the free rides in the amuse¬ ment park where the event was held. The picnic began at 10:00 a. m. and ended at 11:00 p. m. with a “fireworks display from across the lagoon.” The stations are continuing Radio Festival through June with a daily give-away of a radio set. “It is having a very decided effect on the general radio listening,” according to Craig Lawrence, commercial manager. Columbus — WHKC WHKC, Columbus, Ohio, “is right on top in National Radio Festival Week” according to Bob French, production manager. Mr. French wrote: “Not only is this station carrying out the plans for talks and announcements which you outlined, but we are incor¬ porating several ideas of a purely local nature, which we believe will stack up with the best of them. “Again may we thank you for your suggestions and assure you of our utmost cooperation in this very worthwhile ven¬ ture.” Bridgeport — WICC “At the end of this week we will have completed what I feel has been a real effort to sell radio to the public; and especially we have made a great many school children con¬ scious of our industry.” That’s the conclusion of Joseph Lopez, supervisor, WICC, Yan¬ kee Network, Bridgeport, Conn. In addition he wrote: “We began last week carrying special programs made up from the various schools of this area to announce the National Radio Festival and are intensifying this project this week. We have been able to get together some very good programs of school groups and have made this open house at our studios. We are showing in the windows of our New Haven building a display built around the Festival. Last night (June 3) I concluded a series of three talks taken from the ABC of Radio which have also been well received. “About a month ago we began, in cooperation with other Con¬ necticut stations, an essay contest among the children of the 6th, 7th and 8th grades elementary schools, and all grades of high school on the subject: ‘The American System of Broadcasting — Why It is Best for Americans.’ The booklets, ‘The ABC of Radio’ were widely distributed among the schools for reference. “All essays have been submitted to general headquarters for Connecticut at WTIC, Hartford, for judging and awarding of prizes. “This essay contest not only aroused considerable interest but the booklet has been widely examined and has also created addi¬ tional interest in radio. This coming Saturday evening (June 8) we are planning to carry a special half hour program from Hartford to present the winners, etc.” Atlantic City — WBAB The Honorable A. Harry Moore, Governor of New Jersey, was the first Governor of the seaboard states to proclaim National Radio Festival. The event was celebrated during the week of June 3-8. Norman Reed, managing director of WBAB, Atlantic City, secured Governor Moore’s proclamation as well as one by Thomas D. Taggart, Jr., Atlantic City’s Mayor. WBAB maintained Open Flouse throughout the week, presented special musical programs and announcements. A highlight was a 30-minute dramatic presentation on Friday at 9:30 p. m., in which the public was taken behind the scenes in a broadcast station. Engineering IRE CONVENTION The Fifteenth Annual Convention of the Institute of Radio Engineers will be held June 27, 28, 29 at Hotel Statler, Boston, Massachusetts. This year’s program should be of unusual interest to broadcast engineers be¬ cause about half of the program will be devoted to tele¬ vision, frequency modulation, high-power air-cooled tubes, and ultra-high-frequency transmission. Several inspection trips of unusual interest have been scheduled. Probably the outstanding trip will be the one to Paxton to inspect the 50 KW FM transmitter of the Yankee Network. Paul deMars, Technical Director of the Yankee Network, will demonstrate frequency-modulated-wave reception and relay transmission and will illus¬ trate the peculiar merits of frequency modulation. Other inspection trips of unusual interest will be made to the new WBZ 50 KW transmitter, Hygrade Sylvania Tube factory, U. S. Coast Guard air base at Salem, Harvard Engineering and Research Laboratories, General Radio, and Massachusetts Institute of Technology. Eight highly interesting papers will be presented on television. These will be: “A portable Television Transmitter,” by C. D. Kentner, RCA Manufacturing Company; “Small Iconoscopes of Recent Design,” by W. H. Hickok, RCA Manufacturing Company; “A New Method of Synchronization for Television Systems,” by T. T. Goldsmith, R. L. Campbell, and S. W. Stanton, Allen B. DuMont Laboratories; “A Type of Light Valve for Television Reproduc¬ tion,” by J. S. Donal, Jr., and D. B. Langmuir, RCA Manufac¬ turing Company; “Synchronizing and Deflection Circuits of a Television Receiver,” by R. E. Moe, General Electric Company; “Television Radio Relaying,” by F. H. Kroger, Bertram Trevor, and J. E. Smith, RCA Communications; “The Influence of Filter Shape-Factor on Single-Sideband Distortion,” by J. C. Wilson and H. A. Wheeler, Hazeltine Service Corporation; and “High Oscillation Stability Without Crystals,” by S. W. Seeley and E. I. Anderson, RCA License Laboratory. The subject of Erequency Modulation will be well cov¬ ered by six timely papers on the subject. These will be: “Interference Between Stations in Frequency-Phase-Modulation Systems,” by Dale Pollack, Cambridge, Mass. ; “Interference Be¬ tween Two Frequency-Modulated Signals,” by Stanford Goldman, General Electric Company; “A New Broadcast Transmitter Circuit Design for Frequency Modulation,” by J. F. Morrison, Bell Tele¬ phone Laboratories; “Frequency-Modulation-Systems Character¬ istics,” by M. L. Levy, Stromberg-Carlson Telephone Manufactur¬ ing (Tompany; “National Broadcasting Company’s Field Test of Frequency Modulation,” by R. F. Guy and R. M. Morris, National Broadcasting Company ; “Demonstration of Frequency-ModulatedWave Broadcast Systems,” by E. H. Armstrong and P. A. deMars, Columbia University, and the Yankee Network, respectively. R. N. Harmon, of Westinghouse, will describe an air¬ cooled 50 KW transmitter and I. E. Mouromtseff and W. G. Morgan, of Westinghouse, will deliver a paper on large air-cooled tubes for use in 50 KW transmitters. The papers on ultra-high-frequencies and microwaves will include: “Microwaves — Present and Future,” by a Massachusetts Institute of Technology group, led by W. L. Barrow; “UltraShort-Wave Transmission Over a Fixed Optional Path,” by C. R. Englund, A. B. Crawford, and W. W. Mumford, Bell Laboratories; “Centimeter-Wave-Detector — Measurements and Performance,” by E. G. Linder and R. A. Braden, RCA Manufacturing Co.; “A New UHF Tetrode and Its Use in a 1-KW Television Sound Transmitter,” by A. K. Wing, Jr., and J. E. Young, RCA; “An Ultra-High-Frequency Dosemeter-Diatherm,” by J. D. Kraus and R. W. Teed, University of Michigan; “A Radio-Frequency Bridge for Measurements Up to 30 Megacycles,” by D. B. Sinclair, Gen¬ eral Radio Company; “The Measurement of Coil Reactance in the 100-Megacycle Region,” by Ferdinand Hamburger, Jr., and C. F. Miller, Johns Hopkins University; “The Entrance of UltraHigh -Frequencies Into Air-Transport Communications,” by J. G. June 7, 1940 4314
