WSIU-TV, virtual and VHF digital channel 8, is a Public Broadcasting Service (PBS) member television station licensed to Carbondale, Illinois, United States. Owned by Southern Illinois University, it is a sister station to National Public Radio (NPR) member and Public Radio International (PRI) affiliate WSIU (91.9 FM), also licensed to Carbondale. The two stations share studios on the university's campus in Carbondale; WSIU-TV's transmitter is located along US 51 near Tamaroa, Illinois.
WUSI-TV (virtual channel 16, UHF digital channel 23) in Olney, Illinois operates as a full-time satellite of WSIU-TV; this station's transmitter is located on North Shipley Road (County Road 900 E) near Dundas. WUSI-TV covers areas of southeastern Illinois and southwest Indiana that receive a marginal to non-existent over-the-air signal from WSIU-TV, although there is significant overlap between the two stations' contours otherwise. WUSI-TV is a straight simulcast of WSIU-TV; on-air references to WUSI-TV are limited to Federal Communications Commission (FCC)-mandated hourly station identifications during programming. Aside from the transmitter, WUSI-TV does not maintain any physical presence locally in Olney. WUSI-TV is a sister station to WUSI (90.3 FM), also licensed to Olney, which simulcasts the programming of WSIU (FM). WUSI-TV also serves as the default PBS member station for the Illinois side of Terre Haute, Indiana market (where its city of license is located) and the Illinois side of the Evansville, Indiana market (served by fellow PBS members WNIN, Vincennes-based WVUT and Kentucky Educational Television satellite WKOH, respectively).
WSIU-TV operates several UHF translators at the edges of its main coverage area where the station's signal is hard to receive, although it also operates a translator that serves Carbondale. All of these translators map to virtual channel 8 and use the WSIU-TV callsign even though the translators broadcast on different channels. These translators are located in Carbondale (operating on UHF channel 40), Cape Girardeau, Missouri (operating on UHF channel 28), Edwardsville, Illinois (operating on UHF channel 41), and Vienna, Illinois (operating on UHF channel 43).
