On January 27, 1986, WPKX-FM (branded Kix 106) a Country music station changed its call sign to WCXR-FM and instituted its first classic rock format, known as "Classic Rock 105.9". The classic rock format, which was just beginning to take hold in 1986, was considered experimental and debuted to high interest and ratings before eventually falling to more normal levels. The simulcast with 730 AM, now known as WCXR, was broken off around this time.
In 1989, WCXR's owners, the Metropolitan Broadcasting Corporation, sold ten stations including WCXR to Group W. Just four years later, in mid-1993, Group W sold WCXR to Viacom. This fueled rumors of a format change. Viacom elected to keep the format but fired the station's entire air staff, with company officially taking control on November 1, 1993.
A new smooth jazz format, called "Smooth Jazz 105.9," debuted on September 30, 1994.
105.9 FM in Washington, DC is currently used by WMAL-FM (branded 105.9 FM & AM 630 WMAL) and carries a News/Talk format.
