KXLF-TV moved to channel 4 in October 1956 due to concerns that the concurrent operation of channel 6 stations in Butte and Pocatello would result in interference (channel 4 had previously been used in Butte by KOPR-TV from 1953 to 1954, while channel 6 would return to the air in Butte as KTVM in 1970). The following year was a time of change for the station. A complicated operation saw the transmitter moved on top of a mountain east of Butte, subsequently dubbed XL Heights. The transmitter tower was directly positioned on the Continental Divide, thereby giving the station the moniker "The Continental Divide Station." The new transmitter location made an off-air signal available for KXLJ-TV in Helena (now KTVH-DT) creating the first TV "network" in Montana. Also in 1957, KXLF found a permanent home in the former Chicago, Milwaukee, St. Paul and Pacific Railroad station on Montana Street. The station was built in 1916 and features a clock tower. In the 1970s, the depot became one of Butte's first major restoration projects. It continues to serve as an example of historic restoration. In the late 1990s, KXLF installed a live webcam atop the clock tower, which offers a live view of downtown Butte.
