WUSI-TV, virtual channel 16 (UHF digital channel 19), licensed to Olney, Illinois, operates as a satellite station of WSIU. WUSI maintains transmitter facilities located along US 51, near Tamaroa.

WSIU-TV also 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 as 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).[1]

WSIU first signed on the air on November 6, 1961; WUSI signed on as a satellite of WSIU on August 19, 1968.

Analog-to-digital conversion[edit]

WSIU-TV shut down its analog signal, over VHF channel 8, at 9 p.m. on January 29, 2009. The station's digital signal relocated from its pre-transition UHF channel 40 to VHF channel 8 for post-transition operations.[4][5]

WUSI-TV shut down its analog signal, over UHF channel 16, at 9 p.m. on February 17, 2009, the original date in which full-power television stations in the United States were to transition from analog to digital broadcasts under federal mandate. The station's digital signal remained on its pre-transition UHF channel 19.[4][6] Through the use of PSIP, digital television receivers display the station's virtual channel as its former UHF analog channel 16.


During Southern Illinois University's academic year, the station broadcasts a live student-produced newscast, River Region Evening Edition, which airs on Monday through Thursday evenings (on days when classes are held) at 5:00 p.m., with repeats of WSIU InFocus shown on Friday at 5:00 p.m. Three other student-produced programs also air on WSIU, 26:46, Studio A, and Scholastic Hi-Q. Both 26:46 and Studio A occasionally air on the station on Sundays at 10:00 p.m. with Scholastic Hi-Q airing each Sunday a 5:00 p.m.
