Mexican Regulations
RAC

FORWARD

The author is a United States ham operating near Guadalajara, Mexico. That region reputedly houses the largest population of visitors and expatriates from the U.S. and Canada. Some hold non Mexican ham radio licenses, and many of those might like to pursue the avocation in Mexico. It is assumed here they would want to do so legally. Lack of information due to limited Spanish language facility, however, could hinder their understanding of Mexican radio law and practice. This paper offers two items for assistance. One is a  Guadalajara area procedure for obtaining a reciprocal permit. Another is an English language translation of Mexican amateur radio regulations. The procedure for acquiring a reciprocal permit was drafted from personal experience and was valid through the date of this writing, March 1, 2000. Readers should view it as no more than a guide to what may be applicable in the future or other areas. Some information on procedure requirements is included. The law translation was from documents provided by an office of the Mexican Secretary of Communication and Transportation in early 1996. They included the 1988 printing of the law and several directives dated between then and 1995. Materials and revisions subsequently released were obtained through several Internet sites. To the best of the authorís belief, applicability of the source information is current. Translation is more than substituting dictionary words from one language to another. It also involves switching between cultures with familiarity for the manner in which words are organized and understood in particular contexts. The writer enjoys neither fluency in the Spanish language nor special legal expertise and accepts full responsibility for errors. Parenthesized explanatory notations have been added. These materials may be reproduced and distributed in entirety to amateur radio operators by any individual, group, or enterprise only if this is done without financial consideration and associated with no other function than to provide service to amateur radio operators. They may not be reproduced or distributed in any other manner without consent of the author. George Warren XE1/N9VIU Chapala, Jalisco, Mexico March 1, 2000 E-mail: .

OBTAINING A RECIPROCAL PERMIT IN THE GUADALAJARA AREA

Non Mexicans who possess valid amateur radio licenses issued elsewhere are required to obtain a provisional permit before transmitting on the ham bands in Mexico or its waters. These are valid for the remaining time of the Mexican visa and are renewable if the visa is extended. One needs to present an application and pay a tax, as is charged Mexican hams. National telecommunication concerns are administered by the Federal Commission of Telecommunication (COFETEL). They accept permit applications submitted from anywhere b  mail or fax at least 60 days before the date of intended operation. Several ham related Internet web sites contain the necessary forms and directions. A faster approach for those in the Guadalajara area is to apply in person at an office of the State of Jalisco Secretary of Communication y Transportation (SCT). The SCT office of interest is at Avenida Tesistan #477 at the corner with Constitucion in Zapopan. Parking is available inside the grounds. Speak to the department head, Inginero (Engineer) Gilberto Soto, having first secured an appointment by phoning 013-633-2977 or 013-633-0345. From the compoundís entrance, the receptionist will be in the building on the right. Ing. Sotoís office is in the left-hand building. The offices open at 8 A.M. and close at 3 P.M. Arrive no later than mid morning. Provide copies of your passport, visa containing the expiration date of any current renewal, amateur radio license, and local residence proof such as a rent receipt. Also, furnish three passport type photographs. Complete an application form provided by the SCT. Two Spanish language letters could be required. One would be your permit request, the other a recommendation from a sponsoring Mexican ham. Law requires maintenance of a logbook stamped as approved. Its cover must show your name, signature, call sign (prefix "XE1/"), license class, date, and maximum power. The pages must be sequentially numbered. Each contact must have space for date, time on, call sign, RST received, RST sent, frequency, and notes. Request your logbook, new or otherwise, be officially stamped. A four-copy deposit form will be prepared. It will contain your name, address, and the amount of the tax. That was 711 pesos in March 2000. The amount will vary over time. Drive or hail a cab outside the SCT, and take the form and money to the Banamex bank at Plaza Patria in Zapopan. Banamex is on Plaza Patriaís north outside ground level. When paying the tax, the teller will return three of the forms with bank stamps. Request that they be placed on the receiptsí face sides. The SCT needs another receipt copy than those provided. A copy shop is located a few stores east of the bank. Have one copy made showing a stamped face.

Taxi or drive back to the SCT. Enter the building on the right and present the bank forms and copy to the person behind the glass window If this is not all completed within the same day, one must start over and pay the tax again. One of the bank receipts and a form authorizing establishment of your station(s) will be returned. Keep them together as both are required for authentication. Reciprocal permits expressly prohibit operating in contests, DX expeditions, or from the islands of Mexico. Otherwise, privileges are similar to those of the home country license. Station identification will be "XE1/" prefixed to the foreign call sign. Law requires it be given at least every fifteen minutes. This must be in either code, Spanish, or International Telecommunications Union (ITU) phonetics, for which no substitutions are allowed. It must also be followed by the location. The Spanish alphabet sounds much different from English, so non Spanish speakers should use ITU phonetics. During the January following each calendar year the permit has been in force, one must file a report by registered mail that summarizes the past yearís operation. Forms and directions are available from the SCT, the Internet, and packet radio stations.

APPENDIX "A"

BANDS OF FREQUENCIES ALLOCATED TO THE AMATEUR RADIO SERVICE

1800 - 1850 Khz
7000 - 7300 Khz
14000 - 14350 Khz
21000 - 21450 Khz
28000 - 29700 Khz
50 - 54 MHZ
144 - 148 MHZ
24 - 24.05 Ghz * see note
47 - 47.2 Ghz
75.5 - 76 Ghz
142 - 144 Ghz
248 - 250 Ghz

* NOTE

In conformity with number 881 of the Regulations of Radio communications, the band of 24 to 24.25 GHZ is devoted to industrial, scientific, and medical (ICM equipment) applications, for which the amateurs in the band 24 to 25.05 must not cause and must accept interference resulting from said applications.

(Translator note: Other directives of the Secretary, not herein translated, have indicated there are several reasons some frequency bands are missing from this listing and that it should not be assumed that amateurs do not have access to the missing frequencies. For example, purposely omitted were some for which amateurs did not have exclusive use and others which were contested. Other bands were not available for amateur use at the time of regulation publication but have been add ed since. These are addressed and authorized in directives which were later issued but not translated. In general, the allowed frequencies and privileges are the same as U.S. amateurs are allowed while there. One exception relates to the U.S. practice of "incentive" licensing. Whereas the U.S. allows more HF space to those with progressively higher class licenses, Mexico, as most other countries, does not partition the bands in a similar manner with respect to Class I and II licenses. They differ only in allowed power. Other documents, not herein translated, provide for satellite stations and regulate telecommunications in general. ).

APPENDIX C

LOGBOOK

C.1- The amateur is responsible for keeping a permanent logbook at the station with pages sequentially numbered which must be certified by the Secretary by means of the department seal, date, name, and signature of the person certifying. The logbook must clearly note all communications made by the station. The cover must give the name of the operator, callsign, license class, number of the certificate, and the maximum transmitter power. The pages must contain the following date for each contact.
a).- Date and time of the contactís initiation.
b).- Callsign of the contacted amateur.
c).- Signal report sent.
d).- Signal report received.
e).- Frequency of operation.
f).- Observations.

In case of contests, events, or mobil contacts, where it is impossible to immediately register the information, the entries must be estimated and entered before any further information about normal communications from the fixed station. When the operator discovers an error in the logbook content, a new entry must be made immediately following the erroneous one and a cancellation line drawn through the incorrect one leaving it intact in readable form, and the operatorís signature must be appended to the correction.
