WSKW went on the air March 17, 1956 on AM 1150 with the call letters WGHM. In the 1970s the station changed to a Top 40 format with the WSKW call letters, they would then change the call letters to WQMR in the late 1970s and simulcast co-owned WTOS-FM along with an automated classic country format for several years, eventually changing call letters again to WQMR. In the late 1980s as a country music formatted station, the station reverted to WSKW, changed dial positions to AM 1160 and upgraded their signal to 10,000 watts of power. The station switched to sports talk in the mid-1990s originally carriying One on One Sports but later switched to ESPN Radio carrying Boston Red Sox baseball. For a time the sports format was simulcasted on co-owned WHQO (now WFMX). WSKW also carried New York Yankees, Boston Red Sox and Portland Sea Dogs baseball, as well as NASCAR from the Motor Racing Network and local sports. In September 2009 the station dropped all sports programming except for local high school sports in favor of an oldies music format, focusing on the 1960s. For several months WSKW was carried on Northern Maine based WXME as The Legacy Radio Network/The Great 78 and Legacy 1160 before WXME reverted to its previous News/Talk format in the summer of 2010. In December 2010 co-owned WCTB flipped to oldies, with WSKW changing to a simulcast of WCTB in January 2011 before reverting to the sports radio format and ESPN Radio it had held previous to September 2009. In November 2011 the sports format was dropped, as well as local sports in favor of an automated classic country format.
