HistoryEdit

The station first signed on the air on August 27, 1990 as KCMY; it originally operated as an independent station with a general entertainment format. Paxson Communications (the forerunner to Ion Media Networks) 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.

In 2014, KSPX began simulcasting Telemundo affiliate KCSO-LD on digital subchannel 33.2.

Analog-to-digital conversionEdit

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.[2] 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 operationEdit

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. The station will remain at this power level until the spring of 2020.
