WASHINGTON eetem Latest Radio and Communication News, from The National Capital, and Previews of Things to Come NO RELEASE OF FREQUENCIES -As forecast in this column, the Office of Defense Mobilization as the result of the special interdepartmental government study made under its direction announced recently that the "unanimous conclusion" of the survey group was that no VHF frequencies now utilized by the federal government could be released to the FCC for additional television broadcasting allocations. The ODM announcement flatly stated "national security requirements and the needs of air navigation and air communications preclude the release for non -government use of any of the very high frequencies now utilized by the federal government." The ODM report pointed out that, in addition to national security requirements, the programs for guided missiles, radar networks, earth satellites and other defense necessities "have placed and will continue to place an ever -increasing demand for radio frequencies." The ODM added "full national benefit could not be obtained from these vital services without the continued use of frequencies between 50 and 300 MC." TV DEINTERMIXTURE -The FCC viewpoint on the difficult problems of UHF television during the period of its recent intensive study of television problems has been leaning more and more toward deintermixture as the best solution of preserving UHF in cities where that allocation has been demonstrated as rendering good service. The FCC is concerned over the fact that 10% of the nation's population is still without TV service and just a little more than 100 cities have over one local television station in operation. COLOR TV IN ALL HOMES -In the next two decades the FCC leadership feels that in all probability there will be color TV in every home and so that viewers could have a large range of program choice all- channel receivers should be standard. FCC Chairman George C. McConnaughey has proposed a concentrated research program by the manufacturing industry to achieve all- channel transmitters and receivers. If this was accomplished in the near future the FCC would have a sound technical basis for making a long -term decision on UHF, the Commission leadership feels. INCREASED TEMPO -While television dominates the spotlight in the public's knowledge of the FCC, the safety and special radio services, so vital to the nation's economy and fire and police activities, are becoming more important all the time as a responsibility of the Commission. This was pointed out by FCC Chairman McConnaughey in a recent letter to Senate Interstate & Foreign Commerce Committee Chairman Warren G. Magnuson (D., Wash.). The safety- special applications, the FCC chieftain stated, at present approximate 175,000 applications a year. He warned that this rate is continuing to increase substantially "as the need for radio becomes increasingly apparent to the many facets of American industry and for many new applications involving protection of life and property." HIGHER BY 15% -The FCC authorizations in the safety -special services are "now running about 15% higher than last year and about 8%-around 12,000 applications per year- higher" than the Commission estimated in its budget request for the fiscal year 1957 which begins next July 1. To reduce the safety - special backlog to an application processing time of 30 days at the end of the 1957 fiscal year would require $50,000 to $60,000 more than provided in the budget and to place the processing on an even more current basis would require an additional $80,000. JET AIR TRAFFIC CONTROL -The Civil Aeronautics Administration has proposed a $246 million five -year program for a modernized federal air traffic control system designed to keep pace with requirements of the jet age with a large part of the expenditures to go for communications and electronics equipment. The plan, released by CAA Administrator Charles J. Lowen, includes long range radar, airport surveillance radar, peripheral communications, and other navigation and air traffic control equipment. The five -year program calls for putting radar of the short -range surveillance type into 44 additional airports; long -range radar with direct pilot -controller communications into 20 additional air route traffic control centers; a new device known as the radar beacon at 134 locations; and 20 airport surface detection equipment radars to control ground movement at congested terminals. Also proposed are 40 additional airport traffic control towers; 383 VHF omnidirectional radio ranges (VOR) with associated distance measuring service (DME) ; and 28 instrument landing systems. For the 1957 fiscal year $37,500,000 is earmarked for new radar and air navigation facilities. National Press Building Washington, D. C. ROLAND C.
