INTERNATIONAL ELECTROTECHNICAL COMMISSION

Effective 01 August, 2013, the U. S. Coast Guard terminated its radio guard of the international voice distress, safety and calling frequency 2182 kHz and the international digital selective calling (DSC) distress and safety frequency 2187.5 kHz. Additionally, marine information and weather broadcasts transmitted on 2670 kHz will terminate concurrently. See the safety alert. Note that these frequencies are still available and in use, notwithstanding the Coast Guard's termination of the radio guard. Please contact us if you have any questions.


The International Electrotechnical Commmission (IEC) is a worldwide organization for standardization, comprising all national electrotechnical committees (IEC National Committees).

Technical Committee No. 80

Technical Committee 80 - the Maritime Navigation and Radiocommunications Equipment and Systems - develops standards for maritime navigation and radiocommunication equipment and systems making use of electrotechnical, electronic, electroacoustic, electro-optical and data processing techniques, based upon the recommendations for such equipment from the International Maritime Organization and International Telecommunications Union.   IEC TC80 standards are used in type approval/certification of equipment by national authorities such as the US Coast Guard and US Federal Communications Commission.  The national standards organizations of 19 participating countries (Belgium, Canada, China, Denmark, Egypt, Finland, France, Germany, Italy, Japan, Korea (Rep.of), Netherlands, Norway, Romania, Russian Fed., Sweden, UK, USA) comprise the voting membership of IEC TC80. Australia is considering participation membership.

US National Committee

The American National Standards Institute (ANSI) is the U.S. National Committee for IEC.  The US Coast Guard acts as both the Technical Advisor and Technical Advisory Group Administrator for the USNC to IEC TC80.   ANSI requires that all participants in IEC TC80 working groups be registered as members of the USNC TC80 Technical Advisory Group and pay a TAG fee of approximately $300 per person per year (ANSI will invoice participants directly).  Participants for invoicing purposes include voting members, U.S. experts on related TC Working Groups, U.S. delegates to related TC meetings, and corresponding members.  Membership is open to all U.S. national interested parties who indicate that they are directly and materially affected by the activity of the U.S. technical advisory group.  If you reside in the USA and wish to be included in the US TC80 TAG Roster, send an email to CGComms with your request, including your name, address, phone and fax number.   US nationals not listed on the TAG roster may not attend TC80 working group meetings.
