There are 32 FM stations fighting for ears in Mexico City. Most of them run algorithms, chase ratings, and answer to advertisers. Ibero 90.9 does none of those things. Operating from the second floor of Building P on the Universidad Iberoamericana campus in Santa Fe, it has been broadcasting hand-curated alternative music, independent journalism, and genuinely eccentric talk programming since 2003, and in a city that size, that matters. This is the station that calls itself, without irony, "an antidote to intolerable silence."
Born as a Radio-School, Grown Into Something More
The story starts in 2001, when the Universidad Iberoamericana began looking for a broadcast permit. The Secretariat of Communications and Transportation had assigned a provisional permit for a predecessor station as far back as 1991, and the call sign XHUIB-FM was already on air with a tiny 20-watt signal, programming run entirely by students. By 1994 it had grown to 100 watts and 40 broadcast hours per week, but it was still a modest campus experiment.
The real relaunch came on March 8, 2003, timed to the 60th anniversary of the Universidad Iberoamericana. Gabriela Warkentin and Juan Carlos Henríquez, both academics in the university's communications department, conceived it as a "radio-escuela": a training ground for students with workshops in format and genre experimentation, built around a playlist of alternative music that was never going to get airtime anywhere else in the city. The inauguration was marked with a live interview, conducted by veteran journalist Jacobo Zabludovsky, with then-president of Mexico Vicente Fox. The station was, from day one, connecting campus culture to the wider conversation happening outside its walls.
In December 2018, the IFT (Federal Telecommunications Institute) approved a power increase to 10,000 watts, which pushed the signal north and east across Greater Mexico City. Its broadcast license, held by Radio Ibero, A.C., was renewed in 2024 through 2040. In 2026, the station celebrated 23 years on air with a week of special programming and a public conversation on independent media featuring Warkentin, journalist Mario Campos, and news editor Salvador Camarena.
No Algorithm. Every Track Chosen by Hand.
The manifesto on Ibero 90.9's website is worth reading in full, but the core of it is this: "Every song we play is hand-curated. We do not use algorithms or random catalogs." That commitment, held for over two decades, shapes everything about how the station sounds. The music is alternative and eclectic, leaning strongly toward artists and sounds that do not appear on commercial playlists. English-language indie, Latin alternative, electronic, emerging acts from Latin America, ambient and experimental sets, all of it selected by a team of volunteers who actually listen.
- Alternative rock and indie, a mix of English and Spanish-language artists spanning shoegaze, post-punk, bedroom pop, and everything in between. The station has always been comfortable with music that does not fit a genre box.
- Latin alternative and emerging Latin artists, with particular attention to acts from Mexico City's DIY music scene that rarely get coverage on mainstream radio. The station runs regular "Discos del Mes" features highlighting recommended albums each month.
- Electronic music, through dedicated programming including live DJ mixes covering house, techno, funk, and dembow.
- Experimental and ambient, through the "Alquimia Sonora" slot, described on the station's site as a sonic alchemy laboratory, a gallery of ambient pieces and experimental sound.
The station also runs "Extracto," a rotating playlist of tracks the team has been particularly obsessed with, updated monthly and also available on Spotify. It is a good window into the specific taste that has made Ibero 90.9 worth listening to for two decades.
Mexico City's Alternative Scene, and Why This Station Is Part of It
Mexico City has one of the most active independent music scenes in Latin America, with a dense network of small venues, DIY labels, and artists who operate outside the commercial industry. Ibero 90.9 has been connected to that scene since the beginning. When director Alejandro Cárdenas described the station to the Society of Jesus global media office in 2022, he was explicit: "Our music is entertaining... the music of intelligent entertainment. In general, the music we broadcast is alternative, emerging, non-commercial; it seeks to broaden the cultural spectrum of the audience in Mexico City."
What separates Ibero 90.9 from a typical university station is that it operates as a professional broadcaster, not a student training project that happens to be on FM. The Universidad Iberoamericana is a Jesuit institution, and the station's programming reflects that: space for indigenous voices, coverage of migration issues, gender equality programming, human rights reporting. It partners with Jesuit civil society organizations and regularly covers stories that larger Mexico City stations ignore. As of late 2025, the station ran with around 160 volunteers, including students, professors, and community members across disciplines. The station's manifesto captures the spirit well: "We are chemical engineers who play shoegaze, history professors who talk about security and violence, communications graduates doing explanatory journalism."
Programming That Actually Has Something to Say
The talk programming is where Ibero 90.9 most clearly goes its own way. Several shows have become cultural touchstones in Mexico City's media landscape. Fink El Cerdo and Unocero are among the station's most recognized formats, and the station has hosted prominent figures like journalist Gabriela Warkentin (who went on to lead W Radio Mexico), Salvador Camarena, and Mario Campos at various points in its history.
Current programming includes Cassette Blog, which tracks new music from emerging urban scenes worldwide; a show dedicated to electronic live mixes in the DJ set format; Lágrimas Artificiales, focused on contemporary artistic practice; and Los Miércoles Usamos Rosa, a weekly program on culture, music by women, and conversations the station describes as a "safe space." There are also podcasts, including Delirios Crónicos, a narrative journalism series now into its third season, and Archivo General, an exploration of Mexican intellectual history. The station also runs a dedicated journalism section and a cultural events calendar for Mexico City.
Why Ibero 90.9 Is Worth Your Time
If you listen to a lot of radio, Ibero 90.9 has a sound you can identify within a few tracks: unhurried, curious, genuinely eclectic without being scattered. It will play something you have never heard, and then something you recognize, and they will make sense next to each other because someone actually thought about the sequence. That is rare. It is even rarer in a city with 32 competing FM signals and every streaming algorithm in the world also competing for the same attention.
The station's own manifesto ends with the sentence that became its tagline: "Ibero 90.9 is an antidote to intolerable silence." After 23 years without commercials, without algorithms, and without selling out, it has earned the right to say that.
