Public license information
WRTO (1200 AM) is a radio station broadcasting a Spanish-language sports radio format. Licensed to Chicago, Illinois, it is owned by Latino Media Network. Under a local marketing agreement (LMA), it is programmed by previous owner TelevisaUnivision's Uforia Audio Network.
By day, WRTO is powered at 20,000 watts. But 1200 AM is a clear channel frequency reserved for Class A station WOAI San Antonio. So at night, to avoid interference, WRTO reduces power to 4,500 watts. It uses a directional antenna at all times, with a six-tower array. The transmitter is on West 127th Street in Chicago, near the Little Calumet River.
WRTO features local sports programming as well as shows from the Spanish-language sports network "TUDN Radio," originating at other Uforia Audio Network stations.
WRTO is the flagship station of the Chicago Fire of Major League Soccer and the Chicago Bears of the National Football League. It also broadcasts select Chicago Bulls, Chicago Cubs, Chicago White Sox and Chicago Blackhawks games in Spanish.
The station signed on the air in January 1990. Its original call sign was WOPA. It was owned by CID Broadcasting Inc. In 1993, its format was changed from Regional Mexican to Spanish AC.
In 1995, the station was sold to Heftel Broadcasting for $4.5 million. Concurrent with the sale, its call sign was changed to WLXX, and it switched back to a Regional Mexican format branded "La X". On September 20, 1996, the station adopted a tropical music format. On January 12, 2003, the station adopted a Spanish hot AC format branded "Viva", simulcasting 103.1 WXXY. On January 17, 2003, its call sign was changed to WVIV, while its FM sister station's call sign was changed to WVIV-FM.
In October 2003, the station's call sign was changed to WRTO, and it began airing Spanish-language talk programming, which Univision Radio had moved from AM 560 WIND. It became a full time Spanish-language news/talk station in February 2004. WRTO became a part of the Univision America talk radio network on July 4, 2012. While the network itself ceased operations in 2015, WRTO aired remnants of Univision America's programming, as well as its local news, sports, and weather. On March 16, 2017, the station switched to a Spanish language all-sports format, as an affiliate of Univision Deportes.
WRTO was one of eighteen radio stations that TelevisaUnivision sold to Latino Media Network in a $60 million deal announced in June 2022, approved by the Federal Communications Commission (FCC) that November, and completed in January 2023. Under the terms of the deal, Univision agreed to continue programming the station for up to one year under a local marketing agreement.
