Hello. I checked the area surrounding within 2 miles of the fairgrounds for FCC licensees and could only locate this one: Oregon, State of; 460.3125/465.3125 KD22720. The latitude/longitude is in a field 2.5 miles southwest of the fairgrounds, but maybe they were off a little on their FCC application for their license?
The only other choices could be of any Polk, County of licenses:
