KMKY is the second-oldest surviving radio station in the Bay Area. It was first licensed, with the randomly assigned call letters of KLS, on March 10, 1922, on 833 kHz.[2] It moved to 1220 kHz in 1927, then 1440 kHz in 1928. It moved to 1280 kHz in 1937, then 1310 kHz in 1941 as a result of the NARBA agreement. In 1945, when the station was still owned by the Warner Brothers of Oakland, no relation to the movie studio,[3] it changed its call letters to KWBR and changed its format to focus on an African-American audience. In 1959, it was bought by the owners of Memphis radio station WDIA, and the call letters were changed to KDIA. During the 1960s through the 1980s, the station was the premier soul and funk station in the San Francisco Bay Area. Sly Stone was a DJ at the station before launching Sly and the Family Stone.[4]
In December 1984, the station was sold to Adam Clayton Powell III, who turned the station into KFYI, with an all-news radio format backed by a 32-member news team. After Powell failed to make payroll for KFYI – having lost a reported $4-million in funding invested by Aetna Insurance in less than six months on the air – the station went silent on April 9, 1985. It returned to air in July, however, having reclaimed its legacy KDIA call letters, while resuming its urban music format.
In the early 1990s, KDIA was co-owned by then mayor of Oakland, California, Elihu Harris, with then California Assembly Speaker Willie Brown. In 1992, Oakland journalist Chauncey Bailey returned to the Bay Area to work as public affairs director and newscaster on KDIA. Bailey later became the editor of the Oakland Post who was murdered on the streets of downtown Oakland.[5] KDIA changed from gospel music to Radio Disney on December 16, 1997, when the station was sold by Jim Gabbert to The Walt Disney Company.[6]
On August 13, 2014, Disney put KMKY and 22 other Radio Disney stations up for sale, to focus on digital distribution of the Radio Disney network.[7][8][9]
On June 24, 2015, RD San Francisco Assets filed an application to sell KMKY to Radio Mirchi, for $600,000.[10] The sale was completed on October 6, 2015.[11] Radio Disney programming for the region later moved to the KLLC HD3 digital subchannel, where it aired until June 2018.
