By 1962 there were only 13 unduplicated clear channel frequencies left in the United States, and the FCC was investigating whether to "break up" these remaining frequencies by adding secondary stations. In response the U.S. House of Representatives passed House Resolution 714, which gave support to having the frequencies remain assigned exclusively to a single station, and a number of the stations, calling themselves the "Clear Channel Broadcasting Service", applied for higher powers. This included WLW, which submitted an application to operate with 750 kilowatts. However, the FCC denied these applications and went ahead with the additional stations, located mostly in under-served western states. Despite no longer being the sole occupant of 700 kHz, WLW's signal still sometimes spanned impressive distances, and in 1985 overnight host Dale Sommers received a call from a listener in Hawaii. Reception at the United States Air Force's Thule Air Base in Greenland (4235 km) has been reported as sufficiently good for routine listening with an ordinary commercial AM-FM radio receiver at night during the Arctic winter.
