FCC TO WITHHOLD ACTION ON CERTAIN FM EDUCATIONAL APPLICATIONS 
BECAUSE OF POTENTIAL INTERFERENCE TO TELEVISION CHANNEL SIX 


Interference from some educational FM stations to reception of television 
Channel 6 continues to be of concern to the Commission. The problem is widely 
recognized as a problem in the design of the television receiving system. Tele- 
vision sets have been designed in such a way that under certain conditions they, 
are unable to reject the undesired FM signal. The interference problem may also 


-be aggravated when the home TV system includes a broadband booster amplifier. 


Although the problem is basically in the television receiver and does not 
reflect a poor system of frequency allocation, the Commission recently met to 
discuss its concerns about the problem. There is presently a rulemaking (Docket 
No. 20735) scheduled for completion in early fall that will address the problem. 

In the meantime, however, a large number of educational FM applications are 
nearly ready for grant. Therefore, the Commission considered a number of possible | 
steps that could be taken in the interim pending final action on the rulemaking. 


Citing recent cases in Rochester, Minnesota and Corvallis, Oregon where the 
operation of a new educational FM facility has caused severe interference to the 
reception of TV Channel 6, the FCC has decided to temporarily withhold action on 
educational FM applications which pose the greatest potential for interference to 
TV Channel 6. The Commission will withhold further action on ali applications 
for new noncommercial educational FM stations and for major changes in the facili- 
ties of such stations when the proposed facilities are located within the Grade B 
contours of a TV station operating on Channel 6 and where the FM station plans to 
operate on an FM channel between Channels 200 through 207, inclusive. Action will 
not be withheld for FM facilities which are co-located with the Channel 6 station 
regardless of frequency or where the TV station and FM station have reached an 
agreement. This limited delay of application grants will be in effect only until 
the rulemaking in Docket No. 20735 is concluded. - 


Action by the Commission July 16, 1981. Commissioners Fowler (Chairman), 
Quello, Washburn, Fogarty and Jones, with Commissioner Dawson abstaining from 
voting.
