Radio stations from Sonora

Sonora is border country. Its radio dials stretch from Nogales down to Guaymas, from the agricultural valleys of Navojoa and Ciudad Obregón to the beach towns of Puerto Peñasco. For sonorenses living in the United States — and there are many, especially in Arizona and California — the local station is often the strongest thread back home.

Our catalog currently lists 41 live stations from Sonora, and unlike some states where a handful of big groups dominate, Sonora's story is genuinely local: family-owned signals, stations that changed hands between Radiorama, Larsa, ACIR and Uniradio, and frequencies that migrated from AM to FM over the past fifteen years. This article walks through that history using the real stories of real stations, then tells you what to listen to today and how to hear it from the US.

The oldest roots: Guaymas and Ciudad Obregón

Radio in Sonora goes back generations. The earliest station in our catalog's histories is XEDR in Guaymas, which received its first concession in 1938 as the city's first broadcaster, owned by Modesto Ortega and transmitting on 1490 kHz. His successors ran the station for decades. An FM companion, XHDR-FM 99.5, was added in 1994, and the AM signal later moved to 830 kHz with more power. In 2012, after more than seventy years in the hands of Ortega's heirs, the station was sold to Radio Amistad de Sonora, and in late 2017 the family told the telecom regulator it would not renew the AM license. Today that signal survives as Digital 99.5 FM, broadcasting from Guaymas under Grupo Radio Guaymas with a regional Mexican format as La Patrona. One frequency, one family, eight decades.

To the east, in the Yaqui Valley, another long-running signal began on March 2, 1959, when XEEB-AM 1010 received its concession, owned by Radiofónicas de Sonora and transmitting from Esperanza. In 1972 it was sold and became part of Grupo ACIR's operation, moving to Ciudad Obregón. In the early 2000s the station boosted power by moving to 760 kHz, and in 2010 Uniradio took control and brought it to FM, with transmitters on Cerro La Cabana. That station is La Z 98.5 Ciudad Obregón, today a pop station on FM and AM.

Navojoa and the AM generation of the 1950s

Navojoa, in the Mayo Valley, has its own classic. XEKE-AM 980 received its concession on May 15, 1956, and by the 2000s belonged to Joaquín Santiago Terminel Urrea. In 2005 it was sold to Uniradio, and in 2011 XEKE migrated to FM as XHKE-FM 104.5. You can hear it today as KE 104.5 (Navojoa), a grupera station, alongside its companion KE (Navojoa). Navojoa punches well above its weight on our most-listened list: La Zeta (Navojoa), La Nuestra (Navojoa) and KY (Navojoa) all rank among the top streams from the state.

The 1980s and 1990s: new concessions, new towns

A wave of concessions in the 1980s and early 1990s expanded radio across the state. In Hermosillo, XEHOS-AM 1540 received its concession on September 29, 1984, owned by Fernando Fernández Almada, transmitting with 5 kW by day and 2 kW at night. The current owner acquired it in 1993 and raised nighttime power, and in 2011 the migration to FM was approved — though the AM transmitter didn't go dark until six years later. That station is la invasora 101.9 FM Hermosillo, a Uniradio grupera signal that remains one of the state's most streamed.

In Ciudad Obregón, XHFL-FM's concession was granted to Fernando Lema Monge in April 1982; after a period with Radiorama, it now belongs to Uniradio as La Invasora Ciudad Obregón 90.5 FM.

The late 1980s brought more: XESON-AM 680 in Hermosillo was concessioned on November 12, 1988, by the Vidal Martínez family; XEOBS-AM 1070 in Ciudad Obregón followed on March 11, 1988, as a daytime-only station under Radiorama's Futuro Sonoro. And in 1991, XEVSS-AM 650 — transmitting from Villa de Seris with a grupera format called "Morena 650" — began what would become one of the most complicated ownership stories in the state.

The shuffle: how Sonora's modern dial was built

If you've followed Sonora radio for years, you know the names: Radiorama, Larsa, ISA Multimedia, Uniradio. The stations above lived through all of them, and the last decade reshuffled the entire Hermosillo dial.

Take XESON-AM 680. It passed to Grupo ACIR in 2000, migrated to FM in 2011, and ACIR then sold most of its Sonora stations to Radiorama, which handed operation to Larsa. Under Larsa it became Toño, the company's flagship Spanish-hits brand. On August 3, 2019, as Larsa transitioned to ISA Multimedia, the station dropped Toño and became Hermosillo's first Los 40. When ISA's Hermosillo group ceased operations on December 31, 2021, Radiorama took back direct control, and on January 15, 2022 the signal became La Poderosa 88.9 FM Hermosillo — regional Mexican, and today one of the most popular streams from the capital.

Its sister signal XEVSS had an even busier run: grupera as Morena 650, then leased to Radio S.A. in 2002 for the Radio 13 news format fed from Mexico City, then FM migration in 2011–2012 as pop "Sin Límites" under Larsa, then Romántica 101.1 for four years, then grupera as La Más Chingona from 2018. In 2019 that format moved to another frequency and the station became La Ke Buena under ISA — until ISA's exit at the end of 2021. On January 15, 2022, it relaunched as Arroba FM 101.1 Hermosillo, Radiorama's contemporary hit radio format.

Ciudad Obregón followed the same arc. XHOBS migrated to FM in 2011, was leased to Larsa (which ran the English-classics Xtasis format, then Arroba FM pop), then went to ISA in June 2019 with La Ke Buena and news partnerships with Diario del Yaqui and Diario del Mayo. After ISA's exit, a new format debuted in February 2022, followed by a brief format swap in mid-2022 that was reversed three days later. Today the station is Con Madre 92.1 FM Ciudad Obregón, playing grupera.

Not every station changed hands. XHSAP in Agua Prieta, concessioned on August 31, 1993, has belonged to the Zermeño family's Grupo Radiofónico ZER ever since — La tremenda 98.5 FM Agua Prieta. And in Puerto Peñasco, XHPPO (concessioned October 28, 1994, originally for ACIR, transferred to Radiorama's orbit in 2015) spent most of its life as Sol FM, then Los 40, then Súper after Audiorama left the Los 40 network in July 2017. It later moved from 106–108 territory down to 93.5 MHz to clear spectrum for community and indigenous stations, and after a format swap with its sister XHITA it became La Bestia Grupera Puerto Peñasco 93.5 FM.

The stations to know today

Here are Sonora's most-listened streams right now, by city:

Hermosillo

• Stereo 100.3 — the single most-played Sonora station in our directory, a reliable mix for the capital.
• La Mejor Hermosillo — regional Mexican, part of the widely recognized La Mejor brand.
• Radio Lobo MX — a favorite for grupera and norteño.
• La Zeta (Hermosillo) and la invasora 101.9 FM — two Uniradio grupera signals.
• La Poderosa 88.9 FM and Arroba FM 101.1 — the Radiorama pair whose history we traced above.
• La Voz del Pitic — a local name with deep Hermosillo identity.

Ciudad Obregón, Navojoa and the south

• La Mejor Ciudad Obregón and Exa FM Ciudad Obregón
• La Zeta (Navojoa), KE (Navojoa) and KY (Navojoa)

The border and the coast

• Nogales: La Mejor Nogales, La Bestia Grupera, Exa FM Nogales, KY (Nogales)
• Guaymas: Amor 101 for ballads, Digital 99.5 FM for regional
• Agua Prieta: LOS40 Agua Prieta
• Puerto Peñasco: SUPER and La Bestia Grupera
• San Luis Río Colorado: Radio Ranchito and La Consentida

What Sonora sounds like: the genre mix

The numbers tell a clear story. Sonora's dial leans hard regional:

• Regional Mexicano — 16 stations
• Pop Latino y Éxitos — 14 stations
• Banda — 13 stations
• Románticas y Baladas — 6 stations
• Cumbia — 6 stations
• Rock en Español — 5 stations
• Clásicos y Retro — 4 stations
• Electrónica — 3 stations

If you grew up in Sonora, that mix will feel familiar: banda and grupera dominating the valleys, pop stations in the bigger cities, and romantic ballads for the evening. For a taste of the softer side, Amor 101 in Guaymas is a good starting point; for the state's signature sound, any of the La Invasora, La Poderosa or Con Madre signals will do.

Listening from the US: the practical part

Sonora sits mostly in mountain time, like Arizona. That's the easiest time difference of any Mexican state for US listeners: if you're in Phoenix, Tucson, Denver or Albuquerque, the shows air at the same hour as your clock. If you're in California or the Pacific Northwest, Sonora is one hour ahead — a morning show starting at 6:00 in Hermosillo starts at 5:00 for you, which is actually convenient for early risers. For Texas and the Central time zone, Sonora is one hour behind. Most of Mexico abolished seasonal clock changes, so double-check during the weeks when the US has switched and Mexico hasn't.

A few tips that work well for any of these streams:

• Save two or three favorites rather than one — small-market streams occasionally go down for maintenance, and having a backup from a neighboring city keeps the music going.
• Morning drive (roughly 6 to 10 a.m. Sonora time) is when local hosts, news and community segments air; that's the best window if you want the feeling of being there, not just the music.
• Evening and late-night blocks lean on music and dedication shows, ideal background for a US evening.
• If your connection is spotty, let the player buffer a few seconds before muting or switching apps; live streams restart from the live edge, not where you left off.

To find a specific station, browse the Mexico section of the directory and narrow by state, or use the genre pages above to explore by sound rather than by city.

Nearby dials worth exploring

Sonora's radio culture doesn't stop at the state line. Neighboring Sinaloa, with 67 stations in our catalog, shares much of the same banda and grupera DNA — many sonorenses have family ties south of the border in Los Mochis or Culiacán. To the east, Chihuahua offers 54 stations, including signals reachable from Agua Prieta territory. And if you want to compare Sonora's dial against Mexico's biggest markets, Ciudad de México has 350 stations, Guadalajara 59 and Monterrey 52.

Why the history matters

There's a reason this article spends so much time on station histories: in Sonora, the station names themselves carry memory. If you left Hermosillo fifteen years ago, the frequency you remember may now carry a completely different brand — Morena 650, Toño, Los 40, La Poderosa — often within a single decade. Knowing the story helps you find "your" station again, even when the name has changed.

So whether you're tuning in for banda on a Sunday morning in Phoenix, pop from Ciudad Obregón during your commute, or the news voices of La Voz del Pitic on a Tuesday evening, Sonora's 41 live stations are one tap away. Press play, and the desert sounds like home.
