Because AM 1190 is a clear-channel frequency reserved for Class A stations KEX in Portland, Oregon, KDMR must reduce power at night to 500 watts to avoid interference.
On December 20, 1978, the station changed its call sign to KJLA under Owner/general manager Wilton "Chip" Osborn, and played 24-hour disco hits until that music phenomenon faded in 1980.
On July 19, 2002, at 2 pm, Radio Disney made its debut in Kansas City, with the first song being "Complicated" by Avril Lavigne.
[7] In April, Disney filed to sell KPHN to the Catholic Radio Network (a Missouri non-profit Corporation), owner of KEXS.
[10] On December 11, 2016, which is the vigil of the feast day for Our Lady of Guadalupe, the patron saint of Mexico, the station switched to a Spanish-language Catholic radio format.
