The station signed on as a commercial venture in September 1982, however it was not successful and was soon donated to a local religious group. It continued as such until 2003 when the station was sold to the Daystar national charismaticChristian network and, with a few exceptions, ended local programming.
While it was locally produced, the bulk of the channel's programming consisted of fund raising to continue broadcasting.
WTSF shut down its analog signal, over UHF channel 61, in June, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal remained on its pre-transition UHF channel 44. Through the use of PSIP, digital television receivers display the station's virtual channel as its former UHF analog channel 61, which was among the high band UHF channels (52-69) that were removed from broadcasting use as a result of the transition.
