In the mid-1990s, the FCC began to allow low-power stations to have four-letter callsigns, and in September 1995, the station took the call letters KPBI-LP, for Pharis Broadcasting Inc. Pharis also affiliated the station with new network UPN, although the date is uncertain. In June 1998, claiming displacement, Pharis Broadcasting requested to move the station to VHF channel 10; the FCC granted the request in October 1998. Before finishing the move, Pharis sold KPBI-LP to Equity Broadcasting in a deal finalized in June 2001, along with several other stations
One of those stations was KFDF-LP, at the time operating on channel 32. In September 2001, Equity requested Special Temporary Authority to move KFDF-LP to channel 46, being vacated by KPBI-LP. Then, in October 2001, Equity switched the two stations' call letters - KPBI-LP channel 46 became KFDF-CA channel 10, having upgraded its license to Class A on August 27, 2001, and KFDF-LP channel 32 became KPBI-CA channel 46.
KFDF-CA lost its UPN affiliation in September 2006, when the network and The WB closed and merged to form The CW Television Network. Equity Broadcasting originally announced that the station would affiliate with MyNetworkTV, instead of joining The CW, which had no affiliate in Fort Smith until September 2007, when the network and Cox Communications launched a cable channel to carry the network. However, after KPBI-CA lost its Fox affiliation to KFTA-TV, Equity announced that KPBI-CA would join MyNetworkTV, and KFDF-CA would instead join Retro Television Network once UPN went off the air; KPBI was scheduled to join it once WB goes off the air but joined MyNetworkTV on September 22, 2006.
