OR, the former FCC office that used to cover this area has been closed for decades so as long as noone complains, we can run whatever we want (and do!)...
I find only the large groups complain about issues like that.....once, 850 KEYH in Houston lost its programming on the Gentner and stayed at 10KW during critical hours and into night instead of its 180w night signal.....KOA, owned by CC/iHeart, complained....but ONLY because of the CH interference...no mention of the after sunset interference was mentioned or lodged... Go figure...and KEYH is highly directional to the NE...so the interference to KOA was likely at Covington which actually is outside KOA's protected contour...
and the wheels on the bus go round and round.
