KTRB (860 AM) is a commercial radio station in San Francisco, California. The station has a sports-talk format and is known as "Xtra Sports 860". The station switched to sports-talk on May 18, 2009.



KTRB signed on in 1933, broadcasting to the Modesto, California area until June 19, 2006.


Move to San Francisco

KTRB obtained permission from the FCC to move to San Francisco, California and has aired a classic rock music format during transmission tests. KTRB signed on the air to conduct those tests on February 1, 2007.

The station's owner, Pappas Telecasting, established KMPH at AM 840 in Modesto to replace the moved station. It signed on late in 2006.

The San Francisco Chronicle reported that KTRB would debut a hot talk format on March 15, 2007, featuring syndicated personalities Mancow Muller and John London, who once aired on San Francisco stations [1], as well as other syndicated hosts such as Glenn Beck. A similar article appeared a few days later in the San Jose Mercury News.[2]

In the fall of 2008, KTRB became the radio home of Stanford University football and Men's basketball [3]

As of 2009, KTRB is the flagship radio station for the Oakland Athletics.
