XHCHL-FM

XHCHL-FM is a radio station on 90.1 FM serving Monterrey, Nuevo León, Mexico.

In 2017 and 2018, the Bichara family, which owns Núcleo Radio Monterrey, slowly shifted XHCHL toward a new direction, which was completed in early 2018 when the station adopted the name "90.1 FM" and the slogan "Sonamos Diferente"; the Ultra name was added in August.

The format is similar to that used at the time by KJAV-FM in McAllen, Texas, which was owned by members of the Bichara family.

On May 1, 2020, Ultra 90.1 ceased broadcasting, making way for El Heraldo Radio's Monterrey debut.

The news/talk programming moved to XHSP-FM 99.7 upon the newspaper's outright purchase of that station from Grupo Radio Centro; on June 1, 2021, Ke Buena officially launched on the frequency by way of a franchise agreement with Heraldo Media Group.
