SB QST @ ARL $ARLB003 ARLB003 FCC proposes to suspend amateur use of 76-77 GHz ZCZC AG82 QST de W1AW ARRL Bulletin 3 ARLB003 From ARRL Headquarters Newington CT January 16, 1996 To all radio amateurs SB QST ARL ARLB003 ARLB003 FCC proposes to suspend amateur use of 76-77 GHz In a Second Notice of Proposed Rulemaking in ET Docket 94-124, issued just before the Federal shutdown in mid-December, the FCC has proposed amending Part 97 of its rules to ''temporarily disallow amateur use of the 76-77 GHz band,'' which the FCC hopes to open for commercial development along with other ''millimeter wave'' frequency bands above 40 GHz. The band in question is part of the 75.5 to 81 GHz allocation, which the amateur and amateur satellite services share with other users on a primary basis from 75.5 to 76 GHz, and on a secondary basis from 76 to 81 GHz. The primary allocation of 76-81 GHz is assigned to radiolocation, including radar. The commission says the change will permit development of vehicle radar systems in the 76-77 GHz band that could be used in conjunction with Intelligent Transportation Systems. The FCC says restricting ham use of 76-77 GHz will prevent potential interference to these developing systems. At the same time, the FCC proposes to upgrade amateur status in the 77.5-78 GHz band from secondary to co-primary with government and nongovernment radiolocation services. In earlier comments, the ARRL objected to limiting the 76-77 GHz band to vehicle radar systems. The League said it wanted to maintain existing ham allocations from 75.5 to 81 GHz to spur development of short-range, high-speed data links. Because of the Federal government shutdown, the deadline for comments on the FCC proposal has not been set but will be 60 days after publication in the Federal Register. NNNN /EX
