Broadcasting Telecasting (Apr-Jun 1963)

the growing fm field. The new NemsClarke SDM-520 spectrum display monitor ($1,450), which stems from custom gear developed for WTOP-TV Washington, has wide field testing and monitoring applications in fm stereomultiplex broadcasting as well as tv. The SDM-520 measures tv or fm frequency deviation and is capable of determining the amount of sideband or subcarrier attenuation as well as locating spurious radiation and identifying sources of interference. Other new gear is the FMR-101 fm re-broadcast receiver ($950) which permits more efficient and economical fm networking. Riker Industries Inc. added a tv special effects generator to its solid state modular product line. The basic nine-wipe system ($2,560) can be expanded with new modules to comprise the complete system ($4,650) that is capable of virtually unlimited effect combinations. A joy stick control permits full position flexibility with each effect. Vectorscope ■ At the Tektronic Inc. booth the firm's familiar Type 526 color tv vectorscope ($1,655) shared attention with its line of video waveform monitors which now feature illuminated "zero-parallax" graticules on the display scopes for greater accuracy. Special model Type RM527 Mod-132 ($1,230) has all capabilities of the Type RM527 plus line selector and video distribution amplifier features. The line selector, for example, permits detailed analyses of single tv picture lines. Type 527 waveform monitor ($925) and the Type RM527 ($1,000) are the same except for mechanical packaging for varied rack mountings. Television Zoomar Co. unveiled its new lines of all purpose lenses developed by Angenieux-Evershed and Zoomar, including the servo-driven studio 10-to-l zoom model ($8,300). The latter soon will be followed by a smaller system for vidicon cameras. SoundScriber reported great interest in its S-124 monitor ($895) as a result of FCC authorization of automatic program logging. The unit is a continuous tape recorder-reproducer which stores 24 hours on a single 300 ft. tape. Tv station interest in translators this year was greater than in all previous years combined according to Electronics, Missiles & Communications Inc. which introduced its new Emcee 20 w uhf translator ($3,750), a baby version of its 100 w model ($5,900) used for chs. 70-83. Emcee's exhibit attempted to clear up broadcaster confusion over FCC's translator rules, showing many outlets could add translators who are not aware of it. The firm also makes vhf translators and related gear. Telemet Co. introduced its new Telechrome special effects generator, an all-transistorized model filling but 5lA inches of rack space and featuring plugin waveform generator cards which can be added as station needs or budget expand to produce up to 72 different effects. Other transistorized Telechrome gear included color-bar generator, color encoder, EIA sync generator and a full line of distribution and related equipment in module form. The Telechrome test gear and tube-powered lines also were shown. Japan's Sony Corp. showed its new $10,900 video tape recorder entry in the industrial, medical and educational field. Not intended for broadcast use, the Sony PV-100 has 250 lines horizontal resolution and has slow motion playback or complete frame freeze features. Sony has a line of professional audio gear for broadcasters. Film Inspector ■ Harwald Co. displayed its new Mark IV Q automatic 16mm film inspection-editing machine ($5,450) designed specifically for tv use. It features fast and slow forward or reverse, splice and footage counting As broadcasters and scientists employ electronics to increase man's intellect, enabling him to concentrate more on sociological improvement, the world will be able to correct the great mismatch that the space frontier has caused between technological and sociological rates of progress. This was voiced Wednesday by Dr. Simon Ramo, vice chairman of the board, Thompson Ramo Wooldridge Inc., in a talk before the closing luncheon meeting of the NAB's Engineering Conference in Chicago. The engineering conference registration this year passed the 700 mark, well above last year's attendance. "Communications satellites symbolize the world's technological progress," Dr. Ramo said, "and proclaim the broadcasting profession, along with the space and 'intellectronics' scientists, today's technological frontiersmen." Intellectronics, he explained, is the science of extending human mind by electronics. Sidney Metzger, engineer and manager of RCA's Project Relay, predicted the intercontinental transmission of radio and tv through communication satellites will be commercially feasible in the near future. Addressing Tuesday's luncheon meeting, Mr. Metzger related details about the satellite relay now obbiting and recalled technical electronic problems posed before the launch by the space administration. At Monday's luncheon meeting, Dr. Edward E. David, director of the computing information and research center of Bell Telephone Labs., said the future orderly development of economical and automatic stop for any physical defects in the film. The machine also automatically cleans film of surface dirt and electronically applies Protect-OFilm solution. Harwald also showed its standard Model Q inspector-editor ($3,450). With more British-made camera chains entering the U. S. market, even cable system suppliers must keep pace. Boston Insulated Wire & Cable Co., which has supplied tv cable to the tv market ever since the 1939 World's Fair, displayed its new Mark IV camera cable systems which are interchangeable with EMI, Pye and Marconi cameras. Akustische U. Kino-Gerate GMBH introduced its new AKG C-12A capacitor microphone ($485) whose multiple patterns can be selected with the switch on the remote control power box. This small mike has flat response from 10 cycles through 20 kc. AKG also introduced its new D19C model ($55) for general application including fm. overseas voice communications may depend upon transmission of artificial sounds. These would be transmitted within a very small amount of spectrum space and then decoded at the reception point into normal voices. Dr. George A. Town, dean of engineering at Iowa State U., was presented NAB's 1963 Engineering Achievement Award (Our Respects, March 25). Expects No Change ■ Among many speaking during separate radio and tv sessions, Harold L. Kassens, chief of the FCC aural facilities branch, outlined provisions of the commission's new automatic logging rules. He strongly doubted that the FCC would consider any relaxation of the requirement that all equipment be inspected at least five days each week at intervals of at least 12 hours. Mr. Kassens indicated that the FCC is aware this rule may work hardships on those stations which have strayed into the practice of having only an occasional visiting first class engineer. But the commission found that 24% of the renewal applications filed disclosed technical problems requiring attention. His prediction for the next step after automatic logging: transmitters which will correct themselves with respect to frequency stability and adjustment of power within certain limits. Irvin C. Abrahams, consultant in advance engineering for General Electric, described GE's new four-tube vidicon color tv film camera chain which adds monochrome signal for denition (See equipment story page 84).
