Antena Sur broadcasts from Huancayo into a region that does not need convincing to love Andean music. The Mantaro Valley it serves is home to more than 150 active musical groups and an estimated 8,000 working musicians, making a station built entirely around the region's own sound less a niche format than an obvious fit for its audience.
The First Station Built Entirely on Andean Music
Antena Sur describes itself as the first broadcaster in its region with 100 percent Andean music programming, transmitting on 90.3 FM across the Mantaro Valley from its base in Huancayo, Junín, under the slogan "Musicalmente Nuestra," or "Musically Ours." That possessive framing is not incidental. It positions the station as an extension of local identity rather than a regional outlet playing music sourced from elsewhere.
Broadcasting Into a Region Defined by Its Musicians
The density of musical activity in the Valle del Mantaro gives that framing real weight. Research on the region's cultural life counts over 150 musical groups and roughly 8,000 musicians working across it, a scale that turns Andean music from a broadcast genre into daily, lived practice for a significant share of the local population.
The Dance That Defines the Valley
Much of that musical life centers on huaylarsh, the Mantaro Valley's signature regional dance, which the Peruvian government declared part of the nation's Cultural Heritage in 2005. The dance has two distinct strands, an older form tied to agricultural ritual and a modern, festive urban version, both of which remain central to the valley's biggest celebrations, including the Santiago festival that anchors Huancayo's cultural calendar.
A Station Built on Belonging, Not Just Broadcasting
For a station transmitting into a valley this musically active, playing exclusively Andean music is less a programming niche than a direct reflection of what the region already sounds like on any given day. Antena Sur's role is less about introducing listeners to a genre and more about giving a scene that already produces thousands of working musicians a dedicated place on the dial.
