WRLL (1450 AM) is a regional Mexican radio station licensed to Cicero, Illinois, and serving the greater Chicago area. It shares time with WCEV, which broadcasts over the same facilities.
In 2006, WVON, which had long operated on 1450 AM, moved to 1690 AM. The WRLL callsign, which had been held by the original station on 1690 AM, "Real Oldies 1690", was shifted to 1450, and the station adopted a Spanish-language format called "Radio Latino". In 2009 WRLL moved to a more Mexican-oriented format and named itself after the popular Mexican brand "Radio Fórmula". As of 2015 the station dropped the "Radio Formula" name and refers to itself in Spanish as 1450 AM.

WRLL (1690 AM) was an oldies station licensed to Berwyn, Illinois, and serving the greater Chicago area. It was owned and operated by Clear Channel Communications. The station first began broadcasting in early October 2003, and was displaced on the frequency by WVON September 18, 2006.
The station's transmitter was located in Chicago's Ashburn neighborhood, near the Evergreen Park, Illinois border, and operated as a diplexed operaration from one of the towers of its sister station, WGCI (now WGRB). The station ran 10,000 watts during the day, and 1,000 watts at night, using a non-directional antenna.
"Real Oldies 1690", as it called itself on the air, played music from the 1950s and early 1960s, featuring pop artists such as Frank Sinatra and Perry Como as well as the rock and roll hits of the period. "Real Oldies" originated at sister station WSAI (now sports/talk "ESPN 1530" WCKY) in Cincinnati and was also carried on WCOL (now talk station WYTS) in Columbus, Ohio; WHNE in Ann Arbor, Michigan, also a Clear Channel station at that time (now Cumulus business-talk station WLBY), also aired a variation of the format identified as "Honey Radio". "Dangerous Dan" Allen created the format initially for WSAI, where he was program director and a weekday afternoon DJ.
