WKOS (104.9 FM), branded as "104.9 Nash Icon", is a radio station serving the Tri-Cities, Tennessee, area with country music. This station is under ownership of Cumulus Media.


This station was assigned the call sign WGAT-FM on March 13, 1979. It changed calls to WZXY on October 14, 1981, and changed to its current callsign on July 1, 1991.[1] In the early 1980s, WGAT-FM became WZXY, an album-oriented rock station branded "Y105". Sometime in the mid- to late-1980s, WZXY changed its to CHR/Top 40. Through much of the 1990s and a large part of the 2000s, the format was oldies under its new callsign WKOS,[3][citation needed] and then adult hits. The station was called "The Peak" when it changed to hot adult contemporary.
