KFXF's transmitter was located north of Fairbanks and its programming was simulcast on low-power digital translator KFXF-LD (UHF channel 22).

KSEV never signed on, and it would not be until 1992, when the station's owner, Bill St. Pierre, and a group of investors formed Tanana Valley Television, that channel 7 began broadcasting.

In its early years, K07UU/KFXF ran programming from Canadian music channel MuchMusic during the overnight hours, and for a time in 1993–94 carried the NBA on NBC.

The station also ran UPN programs from 2000 until 2006, when that network merged with The WB to form The CW, which is shown on a digital subchannel of KATN.

On November 8, 2016, Northern Lights Media, the subsidiary of Gray Television that operates the Anchorage stations KTUU-TV and KYES-TV, announced that it would buy KFXF-LD, KXDF-CD (then known as KXDD-CD), and KTVF for $8 million in cash, pending FCC approval.
