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. 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 took place later in 2020.[when?]
