WQSR

105.7 WQSR broadcast to Baltimore, Maryland from 1982 until 2001.  These decals most likely date to the mid-1980s but it's unclear what their programming was at that time.  Broadcasting Yearbooks from that era list various formats including MOR, CHR and Adult Contemporary.  By the end of the 80s they were an Oldies station.  WQSR was licensed to Catonsville, MD.
