I took a ride this afternoon to hear what the IBOC hash sounds like as you get close to WLW's tower. As you come within 1 mile of the tower, local WNOP at 740 starts to get buried by analog and digital artifacts. It must be noted, however, that WNOP's 2.0 mv/m contour runs approximately through Mason Ohio, where WLW's tower is located. For all those unfamiliar with the local geography, Mason is located about 25 miles NE of Cincinnati. If WLW was a low powered station, they would be considered a rimshot to Cincinnati.

I was surprised that WNOP could be heard well within 2 miles of WLW. As I got within about 300 feet of the tower, the entire band was messy, although most of the stronger locals and WHAS(Louisville) and WTVN(Columbus) could still be heard. At 1400 kHz, the 1st harmonic, WLW sounded like a local, and the harmonics of the digital sidebands could be heard at 1380, 1390, 1410 and 1420. The harmonics were audible for about 2 miles from the tower, except on 1410 where WING from Dayton rose above the hash, in that their 2.0 mv/m contour also runs approximately through Mason, Ohio.
