WIS 57 was rerouted onto its current alignment between Hilbert and Askeaton in 1932, replacing a former routing to Hollandtown; the original routing was replaced by county roads.
WXER originally broadcast from studios with then co-owned WPLY (1420, now WJUB) on Highway 57 east of the city (which remain the home of WJUB and current sister station WSTM-FM), but in 1994 after WPLY was sold off, moved them to Falls Plaza, a small shopping center off Fond du Lac Avenue in Sheboygan Falls, which were shared by former sister station WCNZ/WCLB (950 AM).

FCC records indicate that the station returned to the air on channel 29 as W29DJ on March 6, 2008, but from a different transmitter located south of Random Lake east of Highway 57, which does not actually cover Sheboygan, and instead broadcasts to communities in southeast Sheboygan County and northeast Ozaukee County.
