On March 29, 1978, the Federal Communications Commission (FCC) granted National Group Television a construction permit to build a new television station on channel 48 in San Jose. The permit took the call letters KQWT before becoming KSTS on January 2, 1979. The station first signed on the air on May 31, 1981 as an independent station. It was owned by National Group Television, which was headed by N. J. Douglas. The station initially offered programming weekdays from 5 a.m. to 3 p.m. from the Financial News Network. From 3 p.m. to 7 p.m. weekdays and from noon to 4 p.m. weekends, the station ran off network shows from the 1950s and early 1960s such as "Fury", "Gentle Ben", "Flipper", "Batman" starring Adam West, "The Danny Thomas Show", "The Jackie Gleason Show" and old low-budget movies. Weekdays after 7 p.m. and weekends throughout much of the day, the station offered various types of brokered programming including foreign language shows, religious programs, and some programming pertaining to technology. The station branded under the slogan "Your Computer Connection". KSTS was also the only station to broadcast the introduction of Apple's Macintosh personal computer at the company's 1984 Annual Shareholders Meeting. Beginning in the fall of 1981, KSTS carried the subscription television service Star TV, featuring recent movies, after 7 p.m. daily.
