KSCO signed on the air on September 21, 1947.[2] It originally was powered at 1,000 watts by day and was housed in a distinctive art deco building, which was constructed for the station, and still broadcasts there today. The founder was Charles Vernon Berlin, who also served as General Manager and Chief Engineer. In 1962, he added 99.1 KSCO-FM (now KSQL).
In 1986, Berlin sold KSCO-AM-FM to Fuller-Jeffrey Broadcasting which owned numerous stations around the country. The AM station went to an automated format of adult standards. On March 10, 1987, KSCO-FM changed its call letters to KLRS (Colors) and its format to a new-age music format, the first station in North America to do so, with Mark Hammond as program director and Jay Peterson music director
Since 1991, KSCO has been owned by the Zwerling family and has a talk radioformat. The Zwerlings later acquired another local AM station, 1340 KOMY. Both Michael and his mother Kay Zwerling took an active role in the station with the former regularly hosting the call-in show Saturday Special and the latter writing and voicing politically conservative commentaries on a variety of topics, especially politics and current events. On January 3, 2017 Kay Zwerling died at 95 years old.[3]

On September 25, 2006, the offices of KSCO and KOMY received an envelope containing white powder. The envelope, which had no return address and contained no letter, was addressed to "AUNTIE KSCO" in handwriting described by Program Director Rosemary Chalmers as "chicken-scratch." Emergency response teams arrived on scene, and all KSCO personnel in the building were evacuated by a HazMat crew. By the evening of Tuesday, September 26, an FBI lab had determined that the powder was inert, and KSCO/KOMY's broadcast studios were deemed safe. Regular broadcasting resumed at 8 p.m. None of the four people who came in contact with the envelope experienced symptoms of any illness.
On October 24, 2022, the FCC proposed a $20,000 fine for Zwerling Broadcasting System, because KSCO had been operating outside of its licensed nighttime parameters since late 1996.[4][5] On December 15, 2022, the FCC denied Zwerling Broadcasting's appeal, and affirmed the $20,000 fine for KSCO.[6][7]
Programming
KSCO/KOMY's studios on 2300 Portola Drive in Santa Cruz, CA
The station programming is a mix of local, syndicated and brokered programming (meaning a person can purchase an available hour of time and produce their own show). A host can either pay for the hour out of his or her own pocket or find local businesses to sponsor the show in exchange for advertising.
The programming is a mix of local and national shows. The morning hours feature a syndicated news and commentary show called Armstrong & Getty, followed by NewsMax host Rob Carson, financial advisor Dave Ramsey, and various local shows covering money management, real estate law, and everything about cars. Afternoon drive time comedy and local interest is hosted by Dave Michaels. Evening and nighttime offerings include Dr. Joel Wallach, Wayne Allen Root, and Coast to Coast AM with George Noory.
KSCO does not subscribe to rating services, so listenership is unreported.
Past KSCO local programs were hosted by Rosemary Chalmers, Michael Olson, Vernon Bohr, Ethan Bearman, Daryl Alan Gault, Rob Roberts, Brian Maloney, and more. Current local hosts include Pamela Fugitt-Hetrick, Duncan McCollum, and Dean Sutton.
