NAB reports (Jan-Dec 1941)

IV : Sound Signal Modulation 13. It shall be standard to use frequency modulation for the television sound transmission. 14. It shall be standard to pre-emphasize the sound transmission in accordance with the independence-frequency characteristics of a series inductance-resistance network havinp a time constant of 100 microseconds. V : Synchronizing Signals 15. It shall be standard in television transmission to radiate the synchronizing waveform shown in Drawing II. 16. It shall be standard that the time interval between the lead¬ ing edges of successive horizontal pulses shall vary less than one half of one per cent of the average interval. 17. It shall be standard in television studio transmission that the rate of change of the frequency of recurrence of the leading edges of the horizontal synchronizing signals be not greater than 0.15 per cent per second, the frequency to be determined by an averag¬ ing process carried out over a period of not less than 20, nor more than 100, lines, such lines not to include any portion of the vertical blanking signal. (See Note A.) VI: Transmitter Ratings 18. It shall be standard to rate the picture transmitter in terms of its peak power when transmitting a standard television signal. 19. It shall be standard in the modulation, of the picture trans¬ mitter that the radio frequency signal amplitude be 15 per cent or less of the peak amplitude, for maximum white. (See Note B.) 20. It shall be standard to employ an unmodulated radiated carrier power of the sound transmission not less than 50 per cent nor more than 100 per cent of the peak radiated power of the picture transmission. 21. It shall be standard in the modulation of the sound transmitter that the maximum deviation shall be plus or minus 75 kilocycles per second. VII: Polarization 22. It shall be standard in television broadcasting to radiate horizontally polarized waves: Note .A: It is recommended that as progress in the art makes it desirable, the maximum rate of change of frequency of the trans¬ mitted horizontal synchronizing signals for studio programs be reduced and that limits be set for transmissions originating else¬ where than in the studio. Note B: It is the opinion of the N.T.S.C. that a picture trans¬ mitter not capable of a drop in radio frequency signal amplitude to 15 per cent or less of the peak amplitude would be unsatisfactory since it would not utilize to the best advantage the available radio frequency power. At the same time the N.T.S.C. is aware of the practical situation that it may not be possible for all of the first picture transmitters to meet this standard. It should be possible in picture transmitters for the lower frequency channels in Group A to meet this standard, although it may not be possible for picture transmitters for the higher frequency channels in Group A to meet it at first. After the first operation on the higher frequency chan¬ nels and as designs progress it should be possible to meet it. It is requested that the Federal Communications Commission take cognizance of this situation. Respectfully submitted, W. R. G. Baker, Chairman. District Meetings RESOLUTION The broadcasters of the 17th NAB District, embracing stations of Washington, Oregon and the territory of ■Alaska in oft'icial .session at I’ortland on this 22nd day of January, Nineteen Hundred and Forty-one resolve: Whereas, for the past three years, C. W. “Chuck” Myers (KOIN-KALE), Portland, has served this district in the capacity of District Director on the Board of the National Association of Broadcasters, and whereas, at Air. Myers’ specific request that he be relieved of further duties in this connection, a new Director for the 17th District has this day been selected to succeed Mr. Alyers for the ensuing two-year term and whereas, Mr. Alyers during the term of his membership upon the Board, and prior thereto, in other industry capacities has faithfully, con¬ structively, able and diligently served the interests of this District and has contributed in a large measure to the solution of industry problems of a national character, and has at all times evidenced a deep personal interest and given attention to problems of individual broad¬ casters within this District, now therefore, be it resolved by the broadcasters of the 17th NAB District that we hereby express to “Chuck” Myers our deep personal and official appreciation for his splendid service and express for him our hope of continued success and well-being. Motion by: Harvey Wixson (KHQ-KGA), Spokane, Washington. Seconded by: John G. Bauriedel (KUIN), Grants Pass, Oregon. Unanimuosly carried.

DISTRICT 10 Fifty-three representatives of Nebraska, Iowa, and Missouri stations defied a mid-west blizzard to attend the 10th District meeting at Omaha on Saturday, the 25th. Director Johnny Gillen, Jr., WOW, received expres¬ sions of deep regret from seven other broadcasters who had planned to be on hand, but who could not make it into Omaha on account of the snow storm. Principal topic of discussion, as at other District meetings, was the music situation. Carl Haverlin, Sta 102 — January 31, 1941
