WNSC-TV and WNSC-FM (88.9) are public broadcasting stations in Rock Hill, South Carolina. WNSC-TV's analog signal is on channel 30 and its digital signal is on channel 15. WNSC-TV is carried on cable channel 15 throughout most of the Charlotte, North Carolina, television market. The stations' studios are on the campus of York Technical College, and their transmitting tower is five miles south of Rock Hill (at 34° 50' 23.00" North Latitude, 81° 01' 6.00" West Longitude).
WNSC-TV went on the air on January 3, 1978. It is a member of the Public Broadcasting Service (PBS) and South Carolina Educational Television (SCETV). It was the sixth full-power SCETV station, and the third public TV station to serve the Charlotte area, after WTVI (channel 42) in Charlotte and UNC-TV's WUNG-TV (channel 58) in Concord, North Carolina. Previously, South Carolina ETV programming had been seen in the Rock Hill area via a low-power translator station on Channel 55 (which is now occupied by WMYT-TV).
WNSC-TV originates some local programming, including Piedmont Politics, and also carries national and statewide programs from PBS and SCETV. Its secondary channels carry the South Carolina Channel (an auxiliary service of SCETV) and ETV-HD.
WNSC-FM signed on in 1979, and was originally known as WPRV. It was the first NPR station in the Charlotte area; the market's flagship NPR station, WFAE, didn't sign on until 1981. It is a member of National Public Radio, carrying programming from SCETV Radio's all-news network. From its sign-on until 2001, it aired a format of NPR news and classical music along with the rest of what was then the South Carolina Educational Radio Network (SCERN). In 2001, it broke off from the rest of the SCERN stations to air jazz music under the moniker of "Carolinas Jazz 88.9" in order to avoid programming conflicts with WFAE. However, on July 1 2008, it switched to all-news. SCETV president Moss Bresnahan told The Charlotte Observer that SCETV didn't want to deny people on the South Carolina side of the Charlotte market access to SCETV's growing slate of local programming. The move left the Charlotte market without a jazz station of its own.
