What is underwriting?

KNSJ 89.1 FM San Diego is a non-profit, non-commercial station supported by donor contributions. Donating to the station is also called “underwriting the station” or “purchasing underwriting”. When your business purchases underwriting, we make on-air acknowledgments of your support. Such on-air spots are not considered traditional advertising because the FCC restricts the content of those spots to be non-commercial in nature.

What can acknowledgments contain?

Underwriting spots may contain factual identification and contact information such as your trade name, location, address, phone number, days and hours of operation, and website. Factual aspects of your products and services may be included, such as brand names, product origin (“French wine”, “Columbian coffee”), intended use (“men’s suits”, “breakfast”), content (“silk blouses”), or form of delivery or method of preparation (“made from grapes”, “cooked with herbs”). Bona fide non-promotional brand slogans that are in well-established use by your business may be included.

What is prohibited?

Underwriting spots may not contain qualitative language (“homemade”, “great”, “wonderful”, “handcrafted”), comparative language (“freshest”, “better”, “most”), calls to action (“call today”, “come by”), number of years in operation (“serving the community for over 20 years”, prices or discounts (not even “sale” or “free”), first-person statements (“I recommend”), second-person statements (“you will enjoy”), or third-person statements (“celebrities eat lunch here”, “where everyone shops”). The location may not be given using another business as reference (“conveniently located across the street from Goudchaux’s”).

Why underwrite community radio?

Underwriting enhances your image as a participant in—and supporter of— KNSJ 89.1 FM San Diego Community Radio. Furthermore, your underwriting is 100% tax-deductible.

Program Schedule

We broadcast a diverse mixture of programming that entertains and educates people’s musical, literary, and cultural interests; inspires action-oriented listeners who seek civic improvement, social justice and fresh visions and artists for San Diego and it’s surrounding communities; nurtures ongoing dialogues across races, cultures and borders; and fosters collaboration for community progress, education and empowerment. The current program schedule appears on a separate page in this packet. Show and personality descriptions are online at www.knsj.org.

Target Audience

Unlike commercial radio stations that typically target a specific demographic based on narrow musical genre interests, community radio covers what the mainstream ignores, thus appealing to the broad spectrum of listeners who are exhausted by traditional media and instead seek a more expansive product reflective of the diversity of cultures and interests in their surroundings. As indicated by the coverage map, over 1 million people in Southern California are in range of our terrestrial FM signal, and our online internet stream is available globally at www.KNSJ.org via the Free “TuneIn” App.

Your underwriting donations are 100% tax-deductible!

KNSJ is a project of 501(c)3 non-profit Activist San Diego.
