103.1 and 93.5 FM History

The 103.1 FM frequency was previously home to WEEF-FM and WVVX. In the 1980s and early 1990s, WVVX was a brokered station with Spanish-language programming during the day and switched at night to "RPM (Real Precious Metal)," a show that became a cult favorite among Chicago-area fans of heavy metal and hard rock music and specialized in playing bands that the major commercial stations in Chicago would not touch. The show was sponsored by Jam Productions, a Chicago concert promoter.

In April 1991, WFYR 103.5 FM (now WKSC) abruptly switched from adult contemporary music to album rock as WWBZ "The Blaze," featuring a more commercial approach to the hard-rock format on a stronger, full-market signals. "The Blaze" quickly took off, and Jam Productions withdrew its support for the heavy-metal programming on WVVX. RPM continued for a short while longer on WVVX and then moved to WYSY in Aurora before being cancelled altogether.
