In 2003, KSBI launched a digital subchannel on virtual channel 52.2, which served as an affiliate of HDNet, one of the few broadcast television stations in the United States to carry the cable and satellite network. In 2004, after Family Broadcasting Group assumed ownership, the subchannel was converted into a simulcast feed of its low-power sister at the time, KXOC-LP (then affiliated with America One). On February 28, 2011, Luken Communications announced that it had reached an affiliation agreement with Family Broadcasting Group to carry Tuff TV on KXOC-LP/KSBI-DT2, which switched to the network on March 7, 2011. During the first few months of the contract, KSBI also carried select Tuff TV programs on its primary 52.1 signal to fill portions of its Saturday afternoon schedule.
