WLOL (1330 AM) is a radio station in the Twin Cities region of Minnesota. It broadcasts a Catholic Radio format and is part of the Relevant Radio network. WLOL's transmitter is located along the Minnesota River in Savage. History WLOL, named for the "Land Of Lakes", is one of the area's most legendary set of call letters. WLOL's history is intertwined with many other local frequencies over the years. The first incarnation of WLOL signed on at 1300 AM on June 16, 1940 and was a part of the Mutual Broadcasting System, a national radio network in the United States. Studios were at 1730 Hennepin Avenue, at Oak Grove Street across from Loring Park, approximately in the current-day airspace over the westbound lanes of I-94 exiting the Lowry Hill Tunnel. The transmitter was in St. Paul's Midway district. WLOL moved to 1330 AM on March 29, 1941 as required by the North American Regional Broadcasting Agreement (NARBA) under which most American, Canadian and Mexican AM radio stations changed frequencies. An FM broadcast began in 1956 when the owners of WLOL purchased WMIN-FM, which had been broadcasting at 99.5 MHz since 1945. The AM station aired a variety of formats over the years, including Top 40 in the 1950s, country music, and a brief return to Top 40 in 1979 as WRRD, "13 Rock", which prided itself as an anti-disco station. Studio locations after the original Hennepin Avenue address include three downtown Minneapolis locations at 1021 LaSalle Avenue, the Northwestern National Bank Building at S. 6th Street & Marquette Avenue, 801 Nicollet Avenue/76 S. 8th Street (same building, alternate addresses), plus 1370 Davern Street in St. Paul (co-located with the station's three antennae), MPR's facilities in downtown St. Paul and later again in downtown Minneapolis at 331 S. 11th Street.
