The FCC granted an original construction permit to Charles R. Meeker on January 24, 1996, to build a low-power television station on UHF channel 45 to serve Cathedral City and Palm Springs, California. It was given the callsign K45ET and began broadcasting in late 1997 as an independent station. Its nickname was "Sun-TV" to represent the desert locale of the Coachella Valley. The station was licensed January 8, 1998, and took the call letters KPSP-LP one month later. In February 1999, Meeker-owned Palm Springs stations KPSP-LP and KDPX-LP switched call letters and programming (see next section), and channel 45 became Pax affiliate KDPX-LP. The station upgraded its license to Class A on September 10, 2001. In June 2005, the Pax network rebranded as i, the new name meaning "independent television" (later changed to "Ion Television"). In 2008, the call letters for the station were changed to KRET-CA. In May of that year, KRET added Retro Television Network. In 2011, KRET added MeTV to its main channel. On May 15, 2018, MeTV was replaced with Heroes & Icons.
