WLIW-FM

The original station was a carrier current station, WSCR, housed in a Southampton College dormitory suite, and run as a student club. The founding members included Aaron Mann, Peter Sarros, Bruce Chappelle, Andy Novick, and Mike Unher. After much of the equipment was lost to theft, and finding the theft covered by insurance, construction of a new stereo FM station began in the basement of Southampton Hall by 1978. The antenna tower was raised in January 1980, and the station went on the air, still as a club and funded by student activity fees, as WPBX at 91.3 MHz on March 11, 1980. The first two songs played were "On the Air" and "DIY" by Peter Gabriel. The original power output of the FM transmitter was ten (10) watts. However, even with this low RF power output, the station could be received by a listener in Sag Harbor, NY, 7 miles away, who employed a yagi type directional antenna, pointed towards the station's transmitter on the Southampton campus. It was completely student-run, with free-form programming, and largely ignored by the administration, until 1981-82 when the administration imposed some control and installed Joseph Valerio to run the station. Valerio arranged to carry Texaco's Metropolitan Opera radio broadcasts and programming began evolving toward an NPR-style format. On July 6, 2002, the station changed its call sign to WLIU.[1] In February 2002, the station changed to a jazz format. In April 2004, the station changed to a news format.

The station broadcast from the second floor of Chancellors Hall on the campus of Stony Brook Southampton until the spring of 2010. The State University of New York at Stony Brook had taken over the LIU campus (previously named Southampton College) in 2006. At the time of the takeover, an agreement was made to permit the station to continue to broadcast from the school through 2009 and that it could continue to use the tower on the campus through 2024.

The transfer of ownership of the station from Long Island University to Peconic Public Broadcasting was completed on December 15, 2010 and the call-letters changed to WPPB to reflect this.[5] The studios were moved to Hill St. in Southampton village after Peconic Public Broadcasting took ownership.

The acquisition was led by Wallace A. "Wally" Smith who was station manager of WLIU. Smith was station manager of KUSC when it converted from an all rock station to a classical music station in Los Angeles, California[6] and was President of that radio station until 1996 (Smith's wife Bonnie Grice was an on air announcer at both KUSC and WPPB. She left WPPB for Sag Harbor radio station WLNG shortly before the announcement of the sale to WNET).[7][8][9] The grassroots effort had included Alec Baldwin, Joy Behar and Jann Wenner.[8] The package for the acquisition was $2.7 million ($1.35 million in cash; picking up $400,000 in transition operating costs; and maintaining WCWP radio station for one year at LIU's parent C.W. Post campus—estimated at $1 million).[10]

On October 24, 2019, it was announced that WNET would acquire WPPB for nearly $1 million, making it a sister to its Long Island PBS member station WLIW.[11] WNET's purchase was consummated on March 18, 2020, at a final price of $944,834. On June 15, 2020, the station rebranded and changed its calls to WLIW-FM, adding more national NPR programming to its lineup.[12][13]
