XHOK-FM

XEOK-AM received its concession on June 19, 1948. It broadcast initially on 950 kHz (soon moving to 920) and was owned by Carlos Roa Montes de Oca, who also built a studio-transmitter link for XEOK in the FM band in the late 1950s. XEOK was sold to Radiodifusión Regiomontana, S.A. in 1963, which boosted its power to 1 kW by the 1980s. In the 1990s, XEOK moved from 920 to 900 kHz which allowed a further power increase to 10,000 watts. ACIR concessionaires have owned XEOK since 2000.

For most of the late 2000s and 2010s, XEOK was a news/talk outlet known as "La OK". With ACIR only owning one station in Monterrey, XEOK was selected for second-wave AM-FM migration and signed on XHOK-FM 90.9 in May 2018. In June, the station took on the Radio Disney format, much like its Guadalajara sister station, XHEMIA-FM.

ACIR and Radio Disney parted ways at the end of 2019. Most of the Radio Disney stations were to change to a similar pop format from ACIR known as Match FM, but ACIR opted to flip XHOK to romantic and place XHOK in its Amor network in December.
