The station was initially licensed in 1991 by Northwestern College of Roseville, Minnesota as WAYG, In 1996, it adopted its current call letters, WSMR. During most of its existence under Northwestern College, the station carried a Christian Adult Contemporary format, with the moniker "Life 89.1". On July 30, 2010, Northwestern College announced that the station would cease broadcasting on August 4 at 5 pm. Northwestern College held a STA to dismantle its current tower and broadcast on another station's auxiliary tower at a lower wattage. A loss of donations from listeners and businesses during the recession has led Northwestern College to close WSMR, even though the special temporary authority filed with the FCC said that the station would continue broadcasting. On the day of WSMR's closure, the University of South Florida announced its intention to acquire WSMR, with plans to change the station's format to classical music, while reimaging Tampa's WUSF FM as a station carrying National Public Radio-based talk programming by day and jazz at night. USF has moved the station slightly closer to the Tampa Bay area; WSMR's coverage is primarily the Sarasota-Bradenton area. However, the station's programming is also heard on WUSF-HD2. WUSF's main frequency began broadcasting an NPR News and talk schedule on September 15, 2010; however, WSMR failed to launch on that date as previously announced. Various explanations were offered by WUSF, including delays due to FCC approval, and an undefined technical issue relating to another frequency assigned to "first responders" at the same tower site. The station's sale to USF also included W280DW, to carry WSMR's new classical signal in Tampa. Two weeks after the failed launch of classical replacement WSMR, station management came under public scrutiny for neglecting to perform due diligence regarding the purchase of the WSMR transmitter. According to a Bradenton Herald article: On October 25, 2010, WSMR resumed broadcasting, but temporarily at 5,000 watts on a Sarasota-area tower rented from Clear Channel Communications. After several weeks, full-power service resumed. WSMR's main studios in Sarasota were completed in early 2011. The studio is used for broadcasting, as well as live and recorded local performances. The station is dedicated to presenting classical music in recorded and live performances and markets itself as Florida's Classical Station. It is available on-line as well around the world. In 2020 WSMR abandoned its stated mission as Florida's Classical Station and introduced a two-hour program during prime time on Sundays featuring 'modern' music that includes atonal and non-melodic pieces that do not resemble classical compositions. No date for the conclusion of the program has been announced.
