WPFM and WDRK swapped formats on November 21, 1997. As a result, WPFM took WDRK's calls and active rock format, while the original WDRK changed their own to WMXP and adopted the "Mix" name, "Mix 103". The new "Rock 108" was ill-fated, and the calls were changed again on October 5, 1998, to WLHR. From this came the widely successful Top 40 station "Hot 107.9". WLHR was changed to WPFM-FM on March 10, 2004, before returning to the WPFM call sign (without the "-FM" suffix) on October 14, 2014.
