The WSLN studios were located on the third floor of Slocum Hall, the Wesleyan Admissions Office Building, and featured basic production tools, a record library, and a live FM studio. The roof location led the station to adopt the motto "It's better on the top." WSLN was licensed for continuous broadcast, but because the station was student-run, the signal was up only when school is in session.
In the fall of 2004, WSLN introduced internet radio.
WSLN's format-free nature made for very diverse programming, and the station programmed vertically so that similar shows were scheduled consecutively. Radio programs on WSLN ran the gamut from bluegrass to independent hip hop to classical, and DJs were restricted only by FCC guidelines. Despite the station's flexibility, there were several long-running programs that were consistent in format, if not in content. WSLN's content largely consisted of music broadcasting, and the station contributed to the CMJ Radio 200 chart.
