XHCH-FM

Osvelia Irene and Oscar Azcue Ruíz became the concessionaires in 1996 after Emma's death, and they promptly sold the station to Grupo ACIR.

It also moved from 1490 to 1040 kHz in order to increase daytime power to 5 kW from its previous 1; it broadcast at night with 750 watts.

On November 6, 2017, XHCH-FM 89.3 signed on as the first in a wave of new AM-FM migrants in large cities in Mexico, made possible by the reduction in mandatory station spacing from 800 to 400 kHz.

Governor Alfredo del Mazo Maza conducted a formal inauguration of the station on November 10.
