That was the plan for a long time, to move WMFN 640, a station 30 kHz from a Chicago local station, as close to WMAQ/WSCR 670 as possible. The 25 mV/m contours of each station can't overlap each other. Took some fancy legal and engineering footwork, but it finally happened. It's licensed to Peotone, IL. They were able to move it because there was another station in Zeeland, WJQK 99.3.Why did WMFN move from Zeeland, MI to Chicago?
