Grand Canyon was one of four firms to apply and the only one from Arizona;[5] Its transmitter facilities were to be located at Hualapai Peak, operating at an effective radiated power (ERP) of 10 kW.

[6] The permit was modified in August 1986 to specify Black Mountain as the transmitter location with an ERP of 100 kW, which was the maximum allowed for a low-band VHF station.

[7] The tower was erected in January 1988, after winter weather forced delays,[8] The station first signed on the air on February 22, 1988, and was licensed on June 1.

From Kingman, Bela hoped to put signals into the Phoenix and Las Vegas markets, both of which have large Hispanic populations.

With KMOH no longer a rebroadcaster of KPNX, Cox Communications petitioned the Federal Communications Commission (FCC) to allow it to exclude the station from must-carry provisions in its 16 Phoenix-area communities, since, while it is part of the Phoenix market, it operates 165 miles (266 km) away from the city itself and the station's signal did not reach into Phoenix.

Raul Infante, Jr. was granted an original construction permit for a television station on UHF channel 31, which was assigned the callsign K31DI, on June 5, 1992, and licensed on August 22, 1995.

Television Apogeo took the station silent in March 2000, but returned it to the air in October, when the company was granted special temporary authority to operate on channel 43.

Una Vez Más Holdings acquired the station in January 2004 and applied to move the transmitter location from Sun City to South Mountain in Phoenix.

Upon taking ownership, Bela again changed the call letters, this time to KEJR-LP, and made the station a translator for KMOH-TV.
