Broadcasting (July - Dec 1936)

CBS Signs Philharmonic NEW YORK Philharmonic Symphony Society will continue to broadcast its regular Sunday afternoon concerts exclusively over the CBS for the next six seasons, according to a new contract recently negotiated on a five-year basis. It will be in force following termination of the present agreement in the spring of 1937. NEW YORK CITY'S board of education has passed a resolution providing that all new school buildings be equipped with a central radio system, with loud speakers in every classroom and auditorium.

ACTUAL EXPERIENCE AT THE CONTROLS Owners and operators of Radio Station W9XBY (New High-Fidelity from Mike to Transmitter— 1000 watts — 1530 kc.) and Experimental Visual Broadcasting Station W9XAL (500 watts on 2800 kc. and 150 watts 42-56; 60-86 megacycles). Theory and practice followed by actual experience in station operation. All Student-Engineers assigned to shifts at controls and transmitter— over 80 remote control pickups weekly. Graduates qualify for Radio-Telephone Operators' License. (First Class.) ATTENTION: Station Owners and New License Applicants: We have available engineer-operators capable of installing and operating new equipment. These men will come fully recommended. TRAINING DIVISION FIRST NATIONAL TELEVISION, INC. (MEMBER N. A. B.) Eng. Dept., Power and Light Bldg., Kansas City, Mo. Purdue and National Television Granted Right to Use Medium Frequency Channel ALTHOUGH major television experiments are expected to take place in ultra-high frequencies, the FCC at an en banc session July 21 granted Purdue University authority to continue its visual broadcasts on its present 2,750 2,850 kc. to Sept. 15 and after that date on 2,000-2,100 kc. National Television Corp., New York, was given special authority to use 2,000-2,100 kc. up to Sept. 15 for tests of its claimed "narrow band" visual system, a decision to be rendered after observation of these tests. The new intercity police radiotelegraph network will occupy the 2,750-2,850 kc. band after Sept. 15 and also will be assigned frequencies in the 2,000-2,100 band with provision that the network will not interfere with Purdue's visual broadcasts. Other services using the latter band are broadcast relay and fixed private and government services. The FCC ruling followed a hearing July 14-16 on the protests of Purdue and National against amendment of Rule 229 to eliminate television from the 2,0003,000 kc. band. Purdue has operated an experimental visual broadcasting station W9XG since 1932 on the 2,750-2,850 band and National Television sought a license on 2,000-2,100 kc. Narrow Band THE HIGHLIGHT of the testimony on behalf of the Purdue station was that its experimentations had demonstrated a wide rural and small-town coverage which could not be accomplished by ultra-short television stations in large cities with their restricted areas of dissemination. The most interesting proposal of National Television was the description of a potential narrow band of only 3,470 cycles for the transmission of television of from 60-100 lines definition. A trio of FCC technical experts — Telegraph Assistant Chief Engineer E. K. Jett, Broadcast Assistant Chief Engineer A. D. Ring and Dr. L. P. Wheeler, technical information director — presented their views of the needs of modern television as well as the frequency requirements in the two bands, 2000-2100 kc. sought by National Television and 2750-2850 by Purdue. Lieut. Jett pointed out that $42 APPROVED BY F. C. C. TRU-AXIS drift CRYSTALS An improved power cut with exceptionally low temperature coefficients. Guaranteed drift not to exceed 3 CPS/Degree C./per Megacycle and tested for this drift over a 50° C. range. Fully mounted in precision Isolantite air-gap holder. FREQUENCY MEASUREMENTS ARE INEXPENSIVE INSURANCE AGAINST OFF-FREQUENCY OPERATION Over 125 commercial stations subscribe regularly to this important service. Single measurements $1.75 each Once-a-week measurements $5.00 r>er month COMMERCIAL RADIO EQUIPMENT COMPANY 7205 Baltimore Avenue RADIO CONSULTING ENGINEERS Kansas City, Missouri since the FCC Rule 229 amendment, eliminating television from these lower ranges, the government had taken over a number of frequencies in the 2750-2850 kc, while there had been in 2000-2100 kc. a number of government and commercial fixed stations. In the latter case there were three nongovernment stations which were broadcast pickup stations. He mentioned the intercity police network due to go in the Purdue band of 2750-2850 kc. and declared it would be impossible for it to operate simultaneously with television. Describing the processes of television picture elements, scanning and details, together with the scientific phases of the art, Dr. Wheeler testified that low definition would not be satisfactory to the receiving person and did not believe enough information had been furnished by National Television to prove its contention of narrow band transmission. He added his view that such a system did not seem possible. Mr. Ring described the present assignments in the lower frequencies to television, citing that Purdue was the only active station out of 11 assignments and gave his views on this low-definition performance. Contrary to press reports to the effect that the FCC engineers had given contradictory reports in their testimony and had been forced to withdraw conclusions under cross-examination of Edward H. Gerber, National Television counsel, Mr. Gerber in his oral argument before the Commission lauded the testimony of Lieut. Jett, and made no concerted attempt to cast aside the other technical views. For National Television, Lieut. Comdr. Edward H. Loftin, USN retired, reported on tests which he had observed on two occasions in that concern's laboratory during this year. He claimed that it had resulted in narrow band television through superimposing modulating frequencies of 20,000 and 40,000 cycles on the carrier frequency and that images had been sent with only 1735 cycles on each side of resonance. He thought this usage had value in wire communication. The two Purdue University professors— Charles F. Harding and R. H. George — described the results of their experiments and transmissions with their television station W9XG since 1932. They stressed that they had received reports of highly satisfactory reception from a number of sections of the country, including many listeners 700 to 800 miles from the stations and one, 1,050 miles away. Aero School on Air BOEING SCHOOL OF AERONAUTICS, Oakland, Cal., to call attention to its summer course in aeronautics, on July 17 started a two-weeks campaign, using oneminute spot announcements twice daily on KGO, KYA, KJBS, San Francisco, and KROW, Oakland.
