Previously the WPMR callsign (for "Pocono Mountain Radio") had been assigned to WPMR (960 AM, now WPLY) and WPMR-FM (107.9 FM, now WKRF) in Mount Pocono/Tobyhanna Township, Pennsylvania.
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).
