WTNR (94.5 MHz, Nash FM 94.5), is a Country radio station located in Grand Rapids, Michigan and licensed to Holland, MI, owned by Cumulus Media. WTNR is one of two Country music stations in the Grand Rapids market, the other being B93.
Prior to the country music format, 94.5 was occupied by WKLQ, with a CHR format, and in 1984 the station flipped formats to hard rock format. In 1996, the station added Howard Stern to the morning lineup. By 1999 the station had tweaked into Alternative and became known as "The Rock@94.5 KLQ". After a few years of struggling with the rock format, the station flipped to country on October 11, 2004 as "94.5 The New Thunder Country".
On October 27, 2011, WTNR completely revamped the station's playlist by adding gold tracks not previously played on the station. These included songs by artists from the 1990s and early 2000s like Garth Brooks, Shania Twain, Brooks & Dunn, Alan Jackson among others. The station also dropped all tags at the end of each song, which gave the title and artist for each track. The station is now simply called "Thunder 94-5" as well.
On July 1, 2012 WTNR re-labeled its brand as "Grand Rapids Country Station, Thunder 94-5".
On February 3, 2014 at 12pm, WTNR along with 9 other Cumulus owned country music stations, dropped the "Thunder 94-5" brand for the Nash-FM branding, with first song as "Nash-FM 94-5" being "Barefoot Blue Jean Night" by Jake Owen.
