KDYA is a radio station licensed to Vallejo, California, but serves the San Francisco Bay Area. It broadcasts on 1190 frequency on the AM dial with an urban contemporary gospel format. It is known over the air as "Gospel 1190 The Light".
Because KDYA shares the same frequency as "clear channel" station KEX-AM in Portland, Oregon, it broadcasts only during daytime hours.
Originally, the station debuted August 1, 1947, as KGYW.
Later, as KNBA -- "Kovers North Bay Area"—the station presented a "middle of the road" (MOR) format. With studios and transmitter on Sonoma Blvd. in the heart of Vallejo, the station was long owned by Louis J. Ripa until his death February 20, 1992.
KNBA was assigned to the frequency 1190 kHz (AM) in 1960; the calls were in use until 1992, when the frequency changed call letters to KXBT, eventually becoming its present call sign, KDYA. 1190's sister-station at 1640 AM is a Christian teaching-ministry format KDIA, also licensed to Vallejo. KDYA is Northen California's ONLY full-time Urban Contempary Gospel station reaching Sacramento, San Francisco, Santa Rosa, and Stockton metropolitan markets. The station carried Oakland Athletics Spanish radio broadcasts in the daytime, while KDIA broadcast night games from 2009 to the middle of the 2010 season.
The KNBA calls are now in use by a radio station in Anchorage, Alaska.
