The KFPH-DT transmitter is located atop Mormon Mountain, about 20 miles (32 km) south of Flagstaff in the Coconino National Forest.

222 Channel 13 in Flagstaff received a construction permit in October 1984, but seven years and a sale passed before the station began broadcasting as KKTM on December 31, 1991.

However, the sale of the station to an affiliate of Paxson Communications Corporation in 1996 heralded its conversion to infomercial programming and, beginning in 1998, the company's new Pax television network as KBPX.

A year later, Michael Gelfand, a doctor from Bethesda, Maryland, acquired the construction permit from Minority Television principal Katherine T.

[17] The call sign was changed to KDUO on June 21, 2001, and the station switched to broadcasting the home shopping service America's Collectibles Network (now Jewelry Television).

Nearly immediately, Equity sold KDUO along with KBGF in Douglas, Arizona, and three low-power TV stations to Univision for $19.1 million in August.
