KNHC (C-89.5) is a student-run Class C1 Non-Commercial FM high school radio station based in Seattle, Washington, primarily broadcasting dance, electronic, and contemporary hit music. It is one of six stations monitored by Nielsen BDS for inclusion in Billboard magazine's weekly Dance/Mix Show Airplay chart. Its best coverage is in the Seattle metro area.
The C in C-89.5 stands for Communications.
Operations and funding
KNHC is owned by Seattle Public Schools and is operated by professional staff who provide practical training to students of Nathan Hale High School in the Lake City area of north Seattle, as part of a radio broadcasting course. Staff supervise students as they perform production, programming, music selection, copy writing, and on-air hosting. Some regular programs are hosted by alumni or non-student volunteers.
Since around 2002, Seattle Public Schools has excluded funding for the station from its annual budget, except for the salaries of district employees. The entire $250,000/year operational budget of the station is raised via fund raising efforts, primarily from a bi-annual pledge drive, as well as from some amount of commercial underwriting. As a non-commercial educational station, it is free of traditional commercial advertisements, though sponsorships are occasionally noted with pre-recorded underwriting spots from the sponsor.
Broadcast coverage and online content
The station's signal is broadcast from Entercom's backup tower on Cougar Mountain, and covers an area from north of Seattle to roughly halfway into Tacoma, Washington and across the Puget Sound. The signal can be received as far east as Snoqualmie Pass and as far north as Victoria, British Columbia. It is licensed to Seattle. C89.5 reports that it currently attracts 200,000 broadcast listeners per week.
The station also provides multiple live streams from its website, currently operating 32 kbit/s and 128 kbit/s SHOUTcast streams and 32 kbit/s and 128 kbit/s Windows Media streams, which can be received throughout the world via the Internet. C89.5 unveiled a major redesign of its website on November 26, 2011, along with a change in URL from c895worldwide.com to c895.org. Other upgrades include a real-time playlist and searchable database of the music that is heard on C89.5.
