Radio stations from Ciudad Obregón, Sonora

Ciudad Obregón, the heart of the Yaqui Valley in southern Sonora, is a city built on agriculture, hard work and a deep love of regional music. For the obregonenses who now live in Phoenix, Tucson, Los Angeles or anywhere else in the United States, local radio is one of the fastest ways to feel back home. The accent of the announcers, the banda tracks, the morning shows with their jokes about the heat — it all travels well over an internet stream.

Our catalog currently lists 12 live stations from Ciudad Obregón, and in this guide we'll walk through the city's radio story station by station, tell you what's on the dial today, and explain the practical details of listening from the US, including the time difference.

A radio story told through its stations

The history of radio in Ciudad Obregón isn't the story of one big broadcaster. It's the story of several frequencies that changed hands, changed bands and changed names over decades — and somehow kept serving the same city. If you follow them in order, you get a picture of how radio developed across Sonora.

The oldest signal: from Los Mochis to 99.3

The most surprising chapter belongs to EXA FM 99.3, known on paper as XHOX-FM. Its story doesn't even begin in Sonora. The station started life as XEOX-AM, which received its concession on September 26, 1939 and went on the air that November 20 from Los Mochis, Sinaloa, owned by Luis Felipe García de León and transmitting on 1230 kHz.

In 1941, for economic reasons, the station moved — frequency and city at once. It relocated to 1340 kHz in Ciudad Obregón, and shortly after to 1430. That move planted one of the city's foundational radio signals. The current concessionaire, Radio Grupo García de León, took over the station in 1977. In 1994 it became an AM-FM combo, with the FM side first transmitting on 106.9 MHz.

The modern era brought more tuning changes: in May 2005, XHOX-FM moved from 106.9 to 106.5 MHz and boosted power from 3,000 to 10,000 watts. And as part of a concession renewal in 2017, the station relocated to 99.3 MHz on May 4, 2018, to help clear the 106-108 MHz range for community and indigenous stations. Three months earlier, on February 8 of that year, it had handed back its AM frequency. So when you stream Exa FM 99.3 today and hear the national Exa format from MVS Radio, you're listening to a signal with roots going back more than eight decades.

The 1950s: two new AM concessions

Radio in the city grew slowly but steadily in the mid-20th century. Two concessions from the 1950s still echo on today's FM dial.

The first became today's Oreja FM 102.5, or XHIQ-FM. It began as XEIQ-AM 960, which received its concession on April 9, 1958 from its original owner, Jesús Corral Ruiz. Over time it was bought by Grupo ACIR, which as it slimmed down sold many stations to Radiorama. Radiorama in turn sold several of its Sonora frequencies to Grupo Larsa — though ACIR kept the concession, an arrangement that still shapes the station today. In April 2012, XEIQ was authorized to migrate to FM as XHIQ-FM 102.5.

The second is now 105.7 La Unika, XHOS-FM, owned like Exa by Radio Grupo García de León. Its ancestor, XEOS-AM 1340, got its concession on July 26, 1956, owned by María Elena Corral de Millán and transmitting with just 250 watts. In 1972 it was acquired by Sistema Radiofónico de Obregón; in 1992 it passed to Sistemas Publicitarios y de Mercadotecnia de Obregón, and two years later to Organización Sonora. In April 2012, XEOS was authorized to migrate to FM, becoming XHOS-FM 105.7 — where it now plays Spanish-language pop.

The 1990s and the Radiorama era

The next wave of stations arrived as national groups expanded into Sonora. Studio 104.9 (XHESO-FM) traces back to XESO-AM 1150, which received its concession on December 10, 1992. It was owned by Radio Signo, S.A., a Radiorama subsidiary, running 5 kW by day and just 300 watts at night. In December 2011, the station was authorized to move to FM as XHESO-FM 104.9.

A similar path led to 92.1 Con Madre, XHOBS-FM, which began as XEOBS-AM 1070 with a concession dated March 11, 1988 — a daytime-only station owned by Futuro Sonoro, S.A., another Radiorama subsidiary. It migrated to FM in 2011.

These AM-to-FM migrations were part of a nationwide shift in Mexican radio, and in Ciudad Obregón they all clustered in the early 2010s. That's why so many of the city's stations carry FM frequencies today even though their identities are much older.

The turbulent years: Larsa, ISA and back

If you left Obregón around 2018 and came back a few years later, the dial probably looked completely different. That's because the city went through one of the most chaotic operator reshuffles in recent Mexican radio.

In the early 2010s, Radiorama rented most of its Sonora stations to Grupo Larsa Comunicaciones. Then everything moved fast:

• April 2018: XHESO dropped the Fiesta Mexicana name and adopted "La Número Uno," styled after XHHQ-FM in Hermosillo. When that XHHQ-Larsa alliance dissolved, it was relaunched in November 2018 as "La Más Chingona," in line with XHVSS-FM. On XHOBS, Larsa dropped the English-classics format Xtasis and went pop with the Arroba FM brand.
• June 2019: ISA Corporativo, an outdoor advertising company, took over operations of XHOBS and XHAP-FM 96.9, immediately switching XHOBS to Televisa Radio's La Ke Buena format and building a news service with the newspapers Diario del Yaqui and Diario del Mayo.
• August 2019: Larsa ceased operations in Ciudad Obregón, knocking three stations off the air temporarily — including XHESO and XHIQ. XHESO returned in September as Los 40 under ISA Multimedia. In November, Radiorama took direct control of XHIQ and XHSM-FM 100.9; XHIQ kept its Spanish-hits format but took the name "Madre 102.5," changing to Oreja FM in June 2020.
• February 2022: After ISA exited radio across Sonora on December 31, 2021, both XHESO and XHOBS launched Radiorama's @FM pop format under direct management.
• June 2022: Con Madre briefly moved from XHOBS to XHAP so that Radiovisa could take over both stations, placing the brand La Que Manda on XHOBS — a change reversed just three days later, with Con Madre back where it belonged.
• September 2025: The Studio classics format moved from XHAP-FM 96.9 to XHESO 104.9, following another operator change.

For listeners, the lesson is simple: brands in Obregón move around, so it helps to follow the station, not just the name. That's exactly what a live directory is good for — you find the stream wherever the format lands.

What to listen to today

Here are the stations our listeners in Ciudad Obregón tune into most:

• EXA FM 99.3 — youth pop hits from the national Exa brand, with the longest history on this list.
• STUDIO 104.9 — classics in English and Spanish from Radiorama.
• OREJA FM 102.5 — Spanish-language hits for adults; the "safe" choice for the whole family.
• 100.1 Radio Vida — Christian programming, one of two faith-based stations in the city.
• 105.7 La Unika — Spanish pop.
• 92.1 Con Madre — grupera, the sound of the valley's working days and weekend parrandas.

A note: you may see what looks like duplicate listings, like RADIO VIDA 100.1 or LA UNIKA 105.7. These are separate stream entries for the same stations — try both if one doesn't load.

Genres on the Obregón dial

The city's musical identity shows clearly in the genre breakdown:

• Pop Latino and hits lead with 7 stations — the strongest signal of a young, commercial market.
• Rock en Español has 5 stations, more than you might expect for a mid-sized Sonoran city.
• News and talk counts 4 stations, keeping obregonenses informed locally.
• Classics and retro and romantic ballads round out the adult audience with 4 and 3 stations.
• The regional soul of the city lives in regional Mexican, banda and Christian formats, with 2 stations each.

That mix — heavy pop on top, but a solid base of banda and grupera — mirrors the city itself: young families, agricultural roots, strong traditions.

How to listen from the US

Streaming Obregón radio from the United States is simple, but a few practical tips make it better:

• Check the time difference. Sonora stays on Mountain Standard Time year-round — it doesn't observe daylight saving time the way most of the US does. That means for part of the year, Obregón matches Arizona (also MST year-round), while other times it's an hour behind states like New Mexico or two hours behind central Texas. Morning shows in Obregón typically air in the early-morning hours for West Coast listeners; if you're on the East Coast, the evening programs are your after-work listening.
• Plan around live programming. News blocks and morning shows are live and time-sensitive; music formats like Exa or Studio work anytime.
• Save your stations. Once you find a stream that loads reliably, favorite it — as the history above shows, formats move, and a saved station page updates automatically.
• Mind your data. If you stream on cellular, remember most radio streams use roughly the same data as a music streaming app.

Explore beyond Obregón

If you want to widen your Sonoran and northern Mexico listening, our catalog covers plenty of nearby regions. Sinaloa, just down the road culturally and geographically, offers 67 stations — fitting, since Obregón's oldest station actually started in Los Mochis. To the east, Chihuahua has 54 stations with a similar norteño flavor.

Farther afield, Guadalajara and the broader state of Jalisco offer 59 and 54 stations respectively, while Monterrey and Nuevo León bring 52 and 41. Veracruz adds 44 stations with a very different, tropical sound. And if you want the biggest dial of all, Mexico City has 350. The full national listing is at Mexico.

Why local radio still matters from abroad

For obregonenses in the US, these stations are more than background music. The news stations keep you connected to what's happening in the Yaqui Valley. The grupera and banda stations play the songs your parents danced to. The Christian stations carry the services and messages that structured home life. And the pop stations, with their national formats delivered in the local accent, hit differently than any US-based Spanish station precisely because they're not aimed at immigrants — they're aimed at home.

Radio in Ciudad Obregón has survived a depression-era relocation, AM-to-FM migrations, and a decade of operator whiplash. The names change; the voices don't. Find your station, save it, and let Obregón play in your kitchen again.
