Broadcasting Telecasting (Jan-Mar 1960)

While seeing a single station market, WTHI-TV fulfills its public service responsibilities in a way that has gained for it the appreciation and support of its entire viewing area ... a circumstance that must be reflected in audience response to advertising carried.

Many exhibits concentrated on the continuing trend to smaller and lighter electronic equipment to meet the demands of the military, of space programmers and industrial design engineers. Miniaturization found tiny tv cameras (one developed by Foto-Video Labs weighed only a few pounds and was less than a foot long), while a lowpower tv station (translator-type transmitter for smaller communities and for educational purposes) was exhibited by Electron Corp., division of Ling-Altec Electronics Inc., (Dallas). Tv "Eye" • A television-equipped "eye" that would orbit the earth in a satellite and operate for several years was discussed by Roy L. Zastrow, senior physicist, research labs div., Bendix Aviation Corp. Orbiting at a 300-mile minimum and 3,000-mile maximum, the tv device may be applied to such peacetime applications as weather reconnaissance, patrolling of sea lanes, seasonal forestry surveys and large-scale mapping. The Bendix scientist indicated that the "eye in the sky" could distinguish such objects on earth as an airliner parked on a runway. Because of the problems of sensitivity requirements at night, the solarbattery powered system will have to "get down to starlight operational level" before continuous coverage will be possible, he said, and the system will continue to be limited to areas not covered by clouds. Mr. Zastrow stated that expected improvements in tube fabrication and automatic control circuitry make feasible installation of an image orthicon system in a satellite. Although vidicon tv cameras are less complex, less bulky and lighter, they are not as sensitive for reconnaissance purposes as is an image orthicon camera. In most applications the tv signal would be telemetered directly to a ground station, avoiding the need for tape recording on the satellite, he said. EIA members oppose any vhf-uhf set law Tv manufacturers are going to oppose legislation which would require that television receivers be capable of receiving the whole vhf and uhf band. This position was taken at a spring meeting of the Electronic Industries Assn. in Washington. The position is a reiteration of previous statements and was approved by EIA committee. EIA has asked to appear in any hearings scheduled by the House or Senate commerce committees. Pending before Congress are bills (S3115 and HR 10817) which would require all tv sets to be capable of receiving the whole band of frequencies allocated for a particular service. The EIA Board approved a resolution asking for Congressional legislation to require permanent marking of country of origin on tubes and semiconductors. It also authorized EIA executive vice president James D. Secrest to call the FCC's attention to the fact that many foreign tv receivers do not meet radiation limitations imposed on U.S. manufacturers. David R. Hull, EIA president and Raytheon vice president, was chosen to receive the EIA 1 960 Medal of Honor. New RCA tube • Radio Corp. of America last week brought out a new monochrome image orthicon (TK-12) television camera equipped with a four and one-half inch "bigimage" pickup tube. RCA says it will achieve high picture quality for live broadcasting or tape recording copies of uniform clarity. The new camera will be shown for the first time at the NAB Convention next week in Chicago. The TK-12's simplicity of operation, RCA reports, does away with the need for constant operator attention to maintain picture fidelity, making it possible for a single operator to handle a group of cameras simultaneously. The big picture tube, a product of RCA's Electron Tube Div., involved the use of a large "target" and a relatively small photocathode — the same size as the photocathode on the standard three-inch tube. Lenses on the new camera need be no larger, according to the company. Electronic magnification produces the large image at the target, resulting in a corresponding increase in picture resolution for finer detail. The camera, which uses RCA's recently developed thimble-size Nuvistor tubes in the video preamplifier and in other camera modules, weighs only 130 pounds.
