KXPI-LD's transmitter is located on Howard Mountain in unincorporated Bannock County west of downtown Pocatello; its parent station shares studios with KIFI-TV on North Yellowstone Highway/US 26 in Idaho Falls.

KRXZ-LP's license originally covered low-power K63GA on channel 63 which was only on the air for less than a year, from August 1999 to July 2000,[2] when it was granted Remain Silent Authority from the Federal Communications Commission (FCC).

K24EV had its call letters changed to KPID-LP (standing for "Pocatello, Idaho") and applied for a license to cover on February 2, 2001, which was dismissed in May[3] because it was not timely filed.

However, Pocatello Media Group's license to cover for KPID-LP was reinstated[4] and granted on June 26, 2001, indicating that the station had finally gotten on the air.

Equity Broadcasting, through its subsidiary EBC Pocatello, Inc., acquired K24EV on February 3, 2003,[5] and changed the call letters to KUNP-LP on March 5, 2004.

In January 2011, the News-Press & Gazette Company (owner of local ABC affiliate KIFI-TV) began operating KXPI-LD and sister station KIDK through shared services agreements.

On June 15, 2012, it was announced that KXPI-LD/KIDK-DT2 would be taking over the Fox affiliation from Intermountain West Communications Company–managed KFXP (channel 31, now KVUI) beginning July 1.
