The purpose of this list is to provide information for the small group of AM broadcast band DX listeners who are interested in identifying radio stations that operate in México. Since sunset-to-sunrise reception on most AM frequencies in North America today is cluttered by dozens of skywave signals of which only fragments can be heard, such minutiae as telephone numbers, street addresses, satellite networks and advertising representatives that can be heard in the few seconds a station may surge to readability on a crowded frequency are useful to help the DX listener identify the station he is hearing.

Even with highly directional receiving antennas and the use of recording devices to pull out fragmented audio clues, other factors make it difficult for the DX listener. Just as in the United States and Canada, AM stations in México are battling for a share of the audience that is dwindling as listener preference switches to FM. This results in changing formats and slogans, or names, of the stations. A station that was, for example, “Radio Fiesta” in 2001, “La Puro Ley” in 2002 and “La Indomable” in 2004 may call itself “Radio Mexicana” in 2005 or may become part of an expanding group headquartered in México City, Monterrey or Guadalajara.

The foundation for this list is the quarterly Medios Publicitarious Mexicanos “Directorio de Medios Audio-Visuales,” the Mexican equivalent of Standard Rates and Data Service, the publication that lists information for timebuyers on each commercial station in the United States. MPM, a quarterly publication, includes commercial AM, FM and TV stations, plus national and regional groups. Most station profiles are headed by a logo, generally with the format of the organization that represents the. The logo is followed by station information, which appears to be provided by either the station or the organization that represents it station and, in most cases, provides a brief description of the station’s  programming.

Some organizations and individual stations try to update this information regularly; others have allowed old information to remain in their listings; in some cases, the logos and the occasional display ads are updated while information in the station profile lags behind. In some cases new station slogans are shown but the format description hasn’t changed. When that occurs, compiler will place possibly outdated format information in parenthesese. In other cases, stations or station representatives have provided no recent information to MPM, in which case the listings will show no logo and will not include format (F), slogan (Sl), and, sometimes, schedule (Sc). Notations -Sl; -F; -Sc mean Slogan and/or Format and/or Schedule are not shown in MPM-03/04 and beyond.

Compiler extracted data on each listed station in the September edition of MPM (MPM-09/06) as the base for this list, comparing it with information in the March 2001 edition of MPM (MPM-03/01), and has subsequently checked the information with editions of the quarterly publication since March 2004. Information from the MPM base is printed in black. While in the process of preparing this list, the December edition of MPM arrived, and compiler has gleaned further changes therefrom.

Compiler has also looked at line-by-line entries in the 2007 World Radio Television Handbook (information color coded in green); the October 11, 2006, Internet listing of AM stations from the Secretaría de Comunicaciones y Transportes (SCT) - Mexican Ministry of Communications and Transport (information color coded in blue); information found on Fred Cantú’s website for station slogans (information color coded in red); geographic coordinates of transmitter sites from the U.S. Federal Communications Commission (information color coded in orange); plus observations by DX listeners, material from various Mexican station and network websites, along with compiler’s notes (information color coded in violet.) Asterisks in various colors indicate information that agrees with data from MPM.

The purpose of providing latest information from each source, often conflicting information, is to indicate to DX’ers using this list questions that may only be resolved by hearing what the station airs, since there no single fully reliable source for Mexican station information.

Individual station listings start with:

FREQUENCY: In kilohertz. Where one list shows a station on a different frequency than the other list, both listings are noted, with comment by compiler as to, when known, which frequency is correct. Compiler will leave old frequencies in the list, though, to help the user as he checks several lists to determine which listing is more likely to be current.

CALL LETTERS: As assigned or aired.

SLOGAN: In black, MPM from the 0906 issue; in green differences in WRTH 2006 or where MPM shows no slogans; in red differences from Fred Cantú’s website; in violet, slogan as heard by DX listeners. Split slogans, such as 13-10 La Jefa” indicate MPM shows slogan as “La Jefa” and WRTH shows slogan as “13-10 La Jefa” For stations that carry Radio Fórmula programming, according to individual station profile in MPM, compiler adds “/Radio Fórmula” to the slogan listing. Because listeners have access to several different lists, circulated annually, it’s hard to keep up with which slogan is current, which has been replaced. As with frequency, the user is advised to consider carefully which information is likely to be current. Asterisks indicate agreement on listed slogans by * WRTH; * Listener’s reports; * Fred Cantú’s website.

LOCATION: Generally speaking, the location is the city in which the main studio is located, according to address in MPM. For many stations, the transmitter site is different from the studio location. Compiler will try to add transmitter sites when known, with notations where known of how the station idenities on the air. For example, XEMCA on 1090 is identified by MPM as a Tampico, Tamaulipas station, but it’s transmitter location is Pánuco, Veracruz, and it identifies on the air as Pánuco. Compiler has heard XEGX on 800, shown by MPM as a Querétaro, Querétaro station, with transmitter at San Luis de la Paz, Guanajuato. This station announces as in San Luis. Several stations that serve the Torreón, Coahuila, market broadcast from studios and transmitters located at Gómez Palacio, Durango. Cities in parenthesis in orange denote transmitter sites identified in the Federal Communications Commission data base; those in parentheses in blue come from Mexico’s Secretería de Comunicaciones y Transportes.

POWER: Accurate information on powers of Mexican stations is hard to come by. Compiler is using powers as shown in MPM (black). Except in some rare instances, MPM does not show night-time powers. WRTH does, and that information has been added to this list, in green. However, accuracy of power listings is questionable. Many stations, heard at night across the border in the United States, are almost certainly using higher power than shown in the night listings. A listing such as (1,000/500) Means that MPM shows power as 1,000 watts; WRTH shows power as 1,000 watts day, 500 watts night. Where MPM and WRTH agree on power, a green asterisk will be added to the MPM-listed power: (10,000*) When powers completely differ, the WRTH power will be shown in green following the MPM power. Compiler has added powers shown in an Internet listing  labeled “Infraestructura de Estaciones de Radio AM,” dated October 11, 2006, from México’s Secretaría de Comunicaciones y Transportes. These powers, where they differ, are shown thus (1,000/500). Where they correspond with MPM and/or WRTH Powers, a blue asterisk * is added. Compiler has also added power information from the FCC data base with the geographic coordinates. List users should compare the FCC information with the SCT information, particularly; FCC’s list may include applications as well as grants, but may also be months or years behind on some notifications. Compiler noted in late 2006 that the FCC list had been significantly amended, making it more useful. An interesting example is found on 810 khz where XEAGR in Acapulco’s power is listed as 1,000 watts by MPM; 1,000 watts day, 150 watts night by WRTH; 7,000 watts day, 600 watts night by SCT in October 2006 (after showing 1,000 watts day, 100 watts night in March 2003); and two entries in the FCC list: 1,000 watts day, 100 watts night at one site, 30,000 watts day, 600 watts night at another. Compiler speculates that XEAGR originally sought 30,000 watts day time and that application showed up in the FCC listings, but when SCT completed its action, the request was pared to 7,000 watts. Compiler as of January 2007 is not aware of the application/grant process by the Mexican equivalent of the FCC or the availability of information from SCT.

SCHEDULE: When schedules listed in MPM and WRTH agree, the MPM schedule will be shown with a green asterisk. Where schedules differ, both schedules will be shown. As this list grows, compiler will add comments based upon times when DX’ers hear these stations, noting that schedules aren’t always accurate. Compiler suggests that the schedule information may be the least reliable of information from these two sources. Confirmation of sign-on and sign-off times by listeners would be valuable information to keep this listing up to date.

ADDRESS: Usually, will be as shown in the latest edition of MPM. Where there may be doubt, earlier or different addresses may be shown, with appropriate comment. Note that the postal code for the station’s address, a five-figure ZIP-like code, will complete the address. In addressing an envelope to the station, the last line should begin with the postal code, followed by the city, the estado, and, of course, México, such as 31700 Nuevo Casas Grandes, Chih., México.

TELEPHONE (T:) and FAX (F:) will follow, with the area code (LADA) in parentheses. Since this listing is prepared primarily to help DX hobbyists identify stations and since most Mexican stations will give telephone numbers and addresses in production identification announcements at least once an hour, these figures can help identify a station heard on a crowded band. In some instances, a number labeled “cabina” is shown. This number apparently connects listeners with the studio.

REPRESENTATIVES: Many of the agencies that sell advertising for owned and/or affiliated stations also provide programming services by satellite and other means. It is helpful to a DX’er trying to identify a station if he hears programming from, slogans or jingles for, or other mentions of the representative, or programming from its satelite network.

WEBSITES: Compiler has included in the January 2007 updated list URLs for station websites, where known. Only those websites with which connection has been established are included.

GEOGRAPHIC COORDINATES: This information, for each station is taken from the U.S. Federal Communications Commission data base Because information in that data base includes accumulated notifications that have been superseded by other notifications, absolute accuracy is impossible. Where the FCC data base shows the station operating on the frequency on which it is listed in this compilation, no notes are added (except for transmitter site, if different from city of license.) Different call letters or different frequencies indicate under which station and frequency the transmitter site is shown in the FCC data base. Bear in mind that a change in frequency or power may have included construction at a different transmitter site, and where different coordinates are shown, compiler has no way of telling which is current. Note, also, that some coordinates are marked with an asterisk. (*) This means the specific station was not in the FCC data base but compiler has arbitrarily shown transmitter coordinates for another station in the same city of license. By plugging the geographic coordinates of the station and the geographic coordinates of the DX’ers location into a formula, such as that available at or, a listener, who may be so inclined, can determine the distance and direction from his location to that of the station.

COMPILER’S NOTES: These follow in violet, and include explanations of changes plus information that comes from listeners’ monitoring reports and other sources, such as station or network websites.

Reps and Nets: National representatives or groups providing sales contracts and, in many instances, programming, are:

ABC Radio: Paseo de la Reforma y Avenida Hidalgo, México, D.F. (55) 55-18-32-93; 55-18-12-67 One of the newest groups headquarters in México, D.F., with primarily information programs furnished to a growing network across the country.

Provides programming to, and sales support, according to its display add in MPM 0904, to 160 statious in 71 cities in México. “Amor,”  “Mix,” and “Satelite”  are primarily FM services, but a few AM stations pick up the slogan and programming. “Radio Felicidad,” “Bonita,” “Inolvidable,” “La Comadre,” and “La Grupera” are the primary AM slogans used by ACIR stations. Beware, though, that ACIR affiliates may use programming and slogans interchangeably, and may also occasionally use “Radio ACIR.” Older lists may show “Spazio” as a slogan for ACIR stations, but that slogan and service have been phased out. XEFR-1180 is “Radio Felicidad” flagship; “Amor” and “Mix” have FM flagships. “Bonita,” “Satelite,” “Inolvidable,” “La Comadre” and “La Grupera” have no D.F. presence.

(Note that “W Radio” network is expanding rapidly, per list on website. Compiler suggests caution, though, that, like many “Radio Fórmula” outlets, old station slogans may still be used during local programming. Listener help sought.)

Listenership: Display ad for Grupo ACIR in 0904 MPM cites Mediómetro INRA 2003 figures showing 25.65 percent of listeners in México listen to Grupo ACIR stations. Other group figures cited in the ad: Radiorama 16 percent; MVS 7 percent; Radio S.A. 6 percent, Radiocima and Ramsa (Fórmula) 5 percent each; Corporadio and OIR/RadioCentro, 4 percent each; Promosat, Direct Deal, Multimedios and Grupo 7, 3 percent each; RASA and Grupo Radio México 2 percent each; others, 9 percent.

Outdated list: In January 2002 compiler prepared a by-frequency list based upon information from the website for the Cámera Nacional de la Radio y Televisión, Mexico’s equivalent of the National Association of Broadcasters in the United States. This listing can be found on the Corazón website, as well as links to other Mexican station information. CIRT’s 2001 list included powers of commercial stations in Mexico but later CIRT lists exchanged station slogan for power. Compiler’s January 2002 list also contained the name of the licensee, as found in the official government listing of Mexican radio stations from the SCT (Secretaría de Comunicaciones y Transportes) and transmitter coordinates for stations listed in the FCC (United States Federal Communications Commission) data base. The CIRT list in 2001 gave station slogans and powers, but more recent CIRT lists dropped the power information and show only the licensee, and it appears the CIRT list has not been updated since 2002.

Important connections: The Internet list that should, in compiler's opinion, be checked frequently for updates is that provided by Fred Cantú, an Austin, Texas, television newsman. Cantú provides basic location, slogan and frequency data on an estado-por-estado basis and, in addition, provides a large number of links to networks and individual stations, including links to streaming audio. Cantú's colorful list is augmented by a good, growing collection of station and network logos … "logotipos" in Spanish. Compiler notes that Cantú, in late 2006, has added powers for Distrito Federal stations, and speculates he may be planning to do the same for the estados. Like any other source of information on Mexican stations, Cantú is ahead of the information curve in several Mexican states and regions, but behind the curve in others. Click  for Cantú's list.

In hopes that the CIRT list will be updated at some time in the future, its URL is

The Corazón website contains many links to useful, but often old or conflicting, information. Rivaling Fred Cantú’s site for detail and frequency of updating is the KOMEX (Kuultavissa Olevat Meksikolaiset) site, compiled by a group of hobbyists in Finland, Sweden and Norway.

The most reliable printed source in the United States is the annual Mexican station list produced by the International Radio Club of America. See for information on IRCA’s publications.

Active DX’ers concentrating on hearing stations broadcasting from Mexico report their findings to the Corazon list, along with the weekly bulletins of the National Radio Club and the IRCA

Help wanted: Each of the many sources used for this list has its weaknesses. There is no known single source for accurate, updated information on AM broadcasting in Mexico. Any additions, corrections, changes or (particularly) establishing contacts with sources that can provide updated information would be gratefully accepted by compiler, John Callarman, 301 W.
