Independent years as KSCH

The station first signed on the air on April 13, 1986, as KSCH.^[3] The first program to air on the station was a "preview" show hosted by Jim Finnerty and Lori Sequest. It was 51 percent owned by Schuyler Communications, Inc., and 49 percent by the SFN Companies.^[4] It originally operated as an independent station and aired classic television series from the 1950s, 1960s, and 1970s, as well as some daytime programs that were preempted by KCRA-TV and KXTV (channel 10). The station originally operated from studios located on West Weber Avenue in Stockton. KSCH was also the first station in the Sacramento market to provide stereo sound from its sign-on.^[3]

On August 9 of that year, SFN sold the station to Pegasus Broadcasting, which consisted of SFN management and outside investors; channel 58 along with three other television stations and three radio stations sold for $154 million.^[5] In 1988, the station moved its studios to a new building located on Gold Canal Drive in Rancho Cordova. In 1990, GE Capital, which had been one of the investors that formed Pegasus, purchased the company outright.^[6]

In 1993, GE Capital began shopping KSCH-TV for sale; in one potential proposal, both KSCH and Koplar Communications-owned KRBK (channel 31, now KMAX-TV) would have been sold to one buyer, who would have been able to sell off one of the stations to a noncompetitive entity.^[7] In 1994, Sacramento restaurant owner Wing Fat and Barbara Scurfield purchased KSCH-TV from GE Capital for $8 million. The new owners entered into a local marketing agreement with Kelly Broadcasting, then-owner of KCRA.^[6] KCRA had launched a 10 p.m. local newscast for the station the year before, and KCRA wanted to operate the station (but could not own it outright under Federal Communications Commission (FCC) rules of the time).^[8]

UPN/The WB affiliation

KQCA/KCRA studios at 3 Television Circle

Once the sale was approved, Kelly immediately made a series of changes. Channel 58 affiliated with the new UPN,^[9] and its call letters were changed to KQCA on February 1, branding as "Q58" (as opposed to a "UPN" and channel number/city branding with many other affiliates at the time). On January 5, 1998, it swapped affiliations with KMAX-TV and became an affiliate of The WB upon the acquisition of channel 31 by UPN.^[10] When Hearst-Argyle Television (which became Hearst Television in 2009) bought KCRA and its LMA with KQCA in 1999, the station dropped its "Q58" branding in favor of using its call letters and channel number. Hearst-Argyle bought KQCA outright in 2000 after the FCC began allowing duopolies, creating the first duopoly in the market in the process; the station adopted the "WB 58" branding in September 2004.

Switch to MyNetworkTV

On January 24, 2006, the Warner Bros. unit of Time Warner and CBS Corporation announced that the two companies would shut down The WB and UPN and combine the networks' respective programming to create a new "fifth" network called The CW.^[11][12] Through CBS's part-ownership of The CW, KMAX was announced as the network's Sacramento affiliate as part of an 11-station affiliation deal.

Logo used until 2019

On February 22, 2006, News Corporation announced the launch of a new programming service called MyNetworkTV, which would be operated by Fox Television Stations and its syndication division Twentieth Television. MyNetworkTV was created to compete against The CW as well as to give UPN and WB stations that were not mentioned as becoming CW affiliates another option besides converting to independent stations.^[13][14] KQCA affiliated with MyNetworkTV when it launched on September 5, 2006, preempting The WB's last two weeks of programming in the Sacramento market. KMAX began broadcasting The CW when it launched on September 18.

From September 5, 2006, to September 18, 2009, KQCA did not follow MyNetworkTV's standard 8 to 10 p.m. prime time scheduling like other affiliates in the Pacific Time Zone, opting instead to air its programming one hour early from 7 to 9 p.m. followed by The Oprah Winfrey Show from 9 to 10 p.m. as a lead-in for the KCRA-produced 10 p.m. newscast (similarly, CBS owned-and-operated station KOVR, channel 13, has carried that network's programming from 7 to 10 p.m. since it switched to CBS in March 1995). KQCA was also one of five MyNetworkTV affiliates on the West Coast that did not follow the 8 to 10 p.m. scheduling: KRON-TV in San Francisco, KEVU-CD in Eugene, Oregon, and KPDX in Portland, Oregon, all aired MyNetworkTV programs from 9 to 11 p.m., while KMYQ (now KZJO) in Seattle aired its programming from 7 to 9 p.m. until September 13, 2010, when that station moved MyNetworkTV programming to 11 p.m. to 1 a.m. On September 21, 2009, KQCA began airing the MyNetworkTV schedule in pattern until September 19, 2014, when the station moved MyNetworkTV programming to 12 to 2 a.m. on a four-hour delay beginning on the 22nd of that month, which has become an increasingly common fate for the service.

In August 2007, KQCA began carrying Oakland Raiders preseason games, assuming the broadcasting rights from KMAX. With the move of the Raiders to Las Vegas in 2020, the station shifted to being an affiliate of the Los Angeles Chargers preseason network the next year.^[15]

In 2019, KQCA unveiled a new "My 58" logo. While it kept the "My" branding, it eliminated the MyNetworkTV-style logo, further deemphasizing on the programming service.

CW affiliation

On August 1, 2023, Hearst agreed to extend its existing affiliation agreements for The CW nationwide, along with adding KQCA to that agreement, assuming the affiliation from KMAX-TV on September 1.^[1] This was part of a broader deal extending The CW's affiliations with Hearst stations in six other markets. KQCA had already served as the market's affiliate for The CW Sports programming (including LIV Golf events) which were not required to be carried under KMAX-TV's previous affiliation agreement.^[16] MyNetworkTV programming remains on the station.^[17] On September 5, 2023, KQCA announced an agreement with UC Davis to air five Aggies college football games from UC Davis Health Stadium, with two featuring pregame content.^[18]

Subchannels

The station's ATSC 1.0 channels are carried on the multiplexed signals of other Sacramento television stations:

Analog-to-digital conversion

KQCA shut down its analog signal, over UHF channel 58, on June 12, 2009, as part of the federally mandated transition from analog to digital television.^[25] The station's digital signal remained on its pre-transition UHF channel 46, using PSIP to display KQCA's virtual channel as 58 on digital television receivers, which was among the high-band UHF channels (52–69) that were removed from broadcasting use as a result of the transition.
