History

The station first signed on the air on August 27, 1990 as KCMY; it originally operated as the area's Home Shopping Club affiliate[1] before joining the InfoMall TV network in the mid-1990s.

In 1995, then-CBS affiliate KXTV agreed to provide some programming to KCMY in order to give it more of a competitive edge in the Sacramento market. KCMY began airing the tabloid show Geraldo at 10 p.m. as well as the KXTV-produced health magazine show Pulse.

Paxson Communications purchased the station in 1998, changing its call sign to KSPX. The station became a charter owned-and-operated station of its new Pax TV network (later i: Independent Television and now Ion Television) on August 31, 1998.

Analog-to-digital conversion

KSPX shut down its analog signal, over UHF channel 29, on June 12, 2009, as part of the federally mandated transition from analog to digital television.[3] The station's digital signal remained on its pre-transition UHF channel 48, using PSIP to display KSPX-TV's virtual channel as 29 on digital television receivers.

Reduced power operation

On August 30, 2019, the station temporarily reduced power, per special temporary authority (STA), from 1,000 kW to 4.3 kW to accommodate relocation of its transmitter site.

Power was increased to 48 kW on November 16, 2019. Another increase to 388 kW took place on April 29, 2020. The completion of the main facility and subsequent increase to 1,000 kW will take place in May 2020.
