WSKW signed on the air on March 17, 1956. It originally broadcast on AM 1150 using the call sign WGHM. The station was powered at 1,000 watts and was a daytimer, required to gooff the air at sunset each evening. It was owned by the Pineland Broadcasting Company. In the 1970s the station changed to a Top 40 format with the WSKW call letters. It changed the call sign to WQMR in the late 1970s and simulcastthe album rock format on co-owned 105.3 WTOS-FM. Later it aired an automatedclassic 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, changing frequencies to AM 1160 and upgrading the signal to 10,000 watts of power in the daytime. The station switched to sports talk in the mid-1990s, originally carrying the One on One Sports Network. It later switched to ESPN Radio, also carrying Boston Red Sox baseball. For a time the sports format was simulcasted on co-owned 107.9 WHQO. WSKW also carried New York Yankees and Portland Sea Dogs baseball, as well as NASCAR races from the Motor Racing Network. In addition, local high school sports were broadcast. In September 2009, the station dropped all sports programming except for local high school sports, flipping to an oldies music format, focusing on the 1960s. For several months WSKW was carried on AM 710WXME in Monticell as The Legacy Radio Network - The Great 78 and Legacy 1160 before WXME reverted to its previous Talk radio format in the summer of 2010. In December 2010, co-owned 93.5 WCTB flipped to oldies, with WSKW changing to a simulcast of WCTB in January 2011. A short time later, WSKW returned to the ESPN sports broadcasts it had held previous to September 2009. In November 2011, the sports format was dropped, along with local sports in favor of an automated classic country format. In August 2019, WSKW returned to using the Legacy 1160 slogan, this time combining 60s and 70s oldies music with local talk shows on weekday mornings and coverage of local high school sports. Well-known local radio personalities Mike Violette and Jon James were the first to sign on under the new format.
