[1] In the station's early years, it aired a full service format, with an hour of jazz weekday afternoons.

[19] In 1993, the station was bought by Mount Wilson FM Broadcasters Inc.[21] In Spring 1994, KTID (AM) ended its simulcast of adult contemporary KTID-FM and began airing Mt.

[23] This occurred after America's last commercial jazz station KJAZ stopped broadcasting in August of the previous year.

Wilson Broadcasters moved the transmitter from Marin to Oakland so as to improve its signal into San Francisco.

The station is unique in that its entire directional antenna array is located on the rooftop of a large warehouse.

Subsequently, KGA eliminated its directional antenna system, and further reduced its nighttime power to 540 watts.

It marked the exit of Mapleton from the radio business, as it was the final sale from their portfolio of stations.

On February 3, 2020, KSFN changed their format from Regional Mexican to Spanish Sports, with programming from Unanimo Deportes Radio.
