KXSC (FM)
KDFC classical music public radio station in Sunnyvale, California, United States
KXSC (104.9 FM) is a radio station based in Sunnyvale, California, serving the southern San Francisco Bay Area. It is owned by the University of Southern California and airs a classical music format as a full-time simulcast of KDFC in San Francisco. The station broadcasts in HD.
History
KXSC began in 1961 as KHYD, a 3,000–watt station operating from a house on Mowry Avenue in Fremont, California.
The station call letters changed to KFMR in 1964. 18-year-old Bill Stairs was among the alumni of early days of KFMR who went on to a career as a DJ, program director and broadcast consultant in markets from Spokane, Sacramento and San Diego in the west to Boston and Chicago in the east. Another early DJ at KFMR was writer Timothy Perrin, winner of the 2007 Angie Award for best screenplay. Under new ownership in the early 1980s, KFMR changed to a religious format.
In 1983, it became Spanish-language KDOS, as La Chiquitita with its studios in Fremont. By December 1983, the station adopted KBRG call letters from 105.3 (now KITS). In 1986, brothers Danny Villanueva and James Villanueva, owners of Radio América, Inc, Bahia Radio, purchased KBRG. The station became "La Nueva KBRG" from 1986 to 1992.

Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Jun 9, 2026. The linked authority identifier is Q6341554. Authority coordinates are 37.323, -121.755. 3 of 3 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank.

Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
