Please don't regard him as an "expert"; he's getting quite old and thinks that "fadiddling fumble-putz" is a more accurate description.

    As anyone who lives near a Navy facility. Eletronics sometimes do funny things when they switch on those big radars 🙂
    Resetting electronics, remote entry keys that don’t work, garage doors that open by themselves. Things like that.

    If a European boat with an AIS B unit installed ventures into US waters, is it breaking US laws by using a device not approved by the FCC?

    I don’t know for sure, Russ, but would bet that it is illegal to transmit within the U.S. on anything that’s not FCC approved. After all, isn’t part of the approval idea to keep the spectrums free of spurious transmissions?
    But I don’t know if the FCC would be very aggressive about hunting down AIS B transponders, though the user would be easily identifiable. We used to have an FCC monitoring field station in Belfast, Maine, but I just found out that it was closed in a 1995 budget cut.

  4. Good morning Ben,
    The Navigation Center (NAVCEN) is the United States Coast Guard’s Navigation Center of Excellence.
    NAVCEN operates the Navigation Information Service (NIS), the Nationwide Differential Global Positioning System (NDGPS), Nation Wide AIS and LORAN. In addition, NAVCEN serves as the civilian interface for the Global Positioning System and manages other navigation-related projects.
    I strongly urge that you report all service degradations, outages, or other incidents or anomalies via the USCG NAVCEN website: http://www.navcen.uscg.gov/

  5. Just ran across an article about the installation of AIS on a buoy in Australia. Check the link at http://www.sealiteusa.com/news/news.php?item_code=142&PHPSESSID=1f3b4bf85d8f96d9ca972138b6400f77
    Some of the info:

    AIS-Enabled TRIDENT-3000 Buoy Launched in Westernport Bay, Victoria
    A truly ‘smart’ Sealite buoy was launched earlier this week by Toll Westernport, in Westernport Bay, Victoria.
    Replacing the existing old-style buoy and incandescent lantern, Sealite’s latest TRIDENT-3000 with SL125 LED AIS-enabled AtoN provides a huge visual and electronic aid for mariners and vessel operators in and around Westernport Bay.
    Developed in accordance with IALA Recommendations, Sealite’s latest AIS-enabled AtoN (Automatic Identification System) was mounted at the top of the tower assembly, enabling maintenance personnel to remotely monitor accurate real-time status of their AtoN installation (Message 6), whilst broadcasting crucial Message 21 information to passing vessels with enabled chart and radar screens (as defined by the International Telecommunications Union- ITU).
