Located on 88.9 MHz, XHM-FM is owned by Grupo ACIR and currently broadcasts news and talk programming, along with blocks of Spanish-language rock from the 1980s and 1990s, as "88.9 Noticias".

The transmitter is located atop a tower in "Ciudad de la Radio" west of the city centre.

Not long after becoming "Radio Metrópoli" and seeing its format move to 99.3 FM, the 1985 Mexico City earthquake severely damaged the station's studios and forced it off the air for a month.

After a brief year as "Fórmula Melódica", XHM finally found a format that stuck, soft adult contemporary "Azul 89", in 1989, with both hits and lesser-known songs in English, French and Italian.

Several of the hosts on 88.9 Noticias were moved to other ACIR radio stations in Mexico City, but the main newscast, the sports programs, a lifestyle nightly show and the traffic reports remained.
