W8XWJ was a Detroit, Michigan "experimental audio broadcasting station", owned by the Detroit News, which operated from 1936 to 1940. It was classified as an Apex broadcasting station, i.e. it provided programming intended for the general public over what was then known as "ultra-high short-wave" frequencies. W8XWJ primarily broadcast unique programming, although it sometimes simulcast programs originating from co-owned AM station WWJ. In April 1940, W8XWJ was shut down, in order to be converted to a commercial FM station.
