KFFX-TV, Fox 11, is a Fox affiliate serving the Tri-Cities, Washington (Richland/Pasco/Kennewick) area. Licensed to Pendleton, Oregon, and owned by Northwest Broadcasting, it also operates a satellite station in Yakima, KCYU-LD channel 41. On satellite, KFFX-TV is normally available on DirecTV although they have been in a contract dispute since August 13, 2012; Dish Network carries KCYU-LD instead. It operates from studios on Falls Avenue in Kennewick.
KFFX-TV signed on the air January 11, 1999. It was the first full-powered VHF station in what had previously been a "UHF island." Distinctively, it is one of two markets where Fox is on VHF, while the other major networks are on UHF; the other one is Austin, Texas (KTBC).
It was also the first station on the Tri-Cities side of the market not to be a satellite of a station in Yakima. Before KFFX-TV's sign-on, cable companies piped in KAYU-TV in Spokane, which operated KCYU as a satellite.

KFFX-TV has been digital-only since February 17, 2009, when KFFX-TV's digital broadcasts moved to VHF channel 11. As the station's transmitter site typically becomes inaccessible to standard vehicles in early November, Northwest Broadcasting provided the station's broadcast engineers with snowmobiles on February 16, 2009 to complete the final post-transition installations.
On April 21, 2009, KFFX-TV added a digital subchannel which includes This TV.
