A TECHNICAL REPORT WAS PREPARED COVERING THE IMPACT OF AIRBORNE TELEVISION TRANSMISSION ON LAND-BASED UHF TELEVISION ASSIGNMENT PLANS. THE REPORT RELATED TO THE PROPOSED EXPANSION PLANS OF THE MIDWEST PROGRAM ON AIRBORNE TELEVISION INSTRUCTION (MPATI). EARLIER STUDIES BY THE NATIONAL ASSOCIATION OF EDUCATIONAL BROADCASTERS (NAEB) HAD LED TO THE DEVELOPMENT OF COMPUTER PROGRAMS WHICH WERE USED IN PRESCRIBING A NEW UHF ASSIGNMENT TABLE. IT WAS THROUGH THE COMPUTER PROGRAM THAT THE IMPACT OF THE PROPOSED MPATI PLANS WAS DETERMINED FOR TWO STANDARDS--(1) MPATI STANDARDS, AND (2) THE ONES DEVELOPED BY NAEB ENGINEERS. IT WAS DETERMINED THAT NO FEWER THAN 60 CHANNELS WOULD BE AFFECTED IN THE MPATI PROPOSAL. UNDER THE NAEB PLAN, 83 CHANNELS WOULD BE AFFECTED. THE NAEB RECOMMENDED CONSERVATION OF AVAILABLE CHANNELS AND THE PRESERVATION OF LOCAL CONTROL OF EDUCATION. IT WAS ALSO RECOMMENDED THAT NO MASS MODIFICATION OF FCC RULES REGARDING UHF PROPAGATION AND INTERFERENCE STANDARDS BE MADE. (JC)
