KZST is a radio station based and licensed in Santa Rosa, California, with a frequency of 100.1 MHz. Its first broadcast came on April 18, 1971 (the 65th anniversary of the Great earthquake), making KZST "the first FM station between here (the San Francisco Bay Area) and Portland, Oregon."
Founded by Gordon Zlot, KZST remains under the ownership of his company, Redwood Empire Stereocasters. The station plays adult contemporary music, with a family-friendly format aimed at so-called soccer moms who often listen to the radio with their children present.
Brent Farris has broadcast his weekday "Morning Showgram" for more than 25 years, the longest current tenure of any radio host in Sonoma County. Jim Grady, the weekend morning host, held that distinction until March 26, 2004, when he was released from news/talk station KSRO after 44 years.
"Smooth 93.7" KJZY-FM shares the same building and ownership.
