On January 16, 2024, KUSI and KSWB-TV began their shared broadcast in the NextGen ATSC 3.0 format on UHF-TV channel 18 in San Diego.

Viewers who want to continue to receive KUSI over the air will need to perform a RESCAN on their TVs. This is generally done by entering the MENU, then looking for SIGNAL or RF or ANTENNA, selecting AIR (not CABLE), and AUTO-PROGRAM or SCAN or ADD CHANNELs on the MENU.

Their December 11, 2023 FCC application specified having the KUSI channel 18 transmitter hosting KSWB-TV “Fox 5” and ATSC 1.0 on the KSWB-TV channel 26 transmitter hosting KUSI, each atop Mt. San Miguel.

The FCC recently approved Nextstar’s purchase of KUSI. The two stations are now co-owned and are moving into the established KUSI studio facility in Murphy Canyon. 

Some models of commonly available television sets now include NextGen tuners. KRPE-LD channel 6 on Mt. San Miguel was the first area station to begin the NextGen service.
