    Maris and Dura Mater made individual calls to each other through their AIS MMSI numbers today. And it worked. Of course, the volume on my radio was turned down and I had to turn it up in order to hear Brian. That old joke. Now I know my AIS works. Brian Boschma says large container ships tend to not respond to "Container ship at [lat/long]", but they DO respond when their name is used: "Dura Mater to the Container ship 'Maersk Dunga Din'".

    Glad it worked. As MMSI is essentially a specific ship to ship call, I'm guessing they're more likely to respond. You'll get really tired of the AIS alarm on the SH VHF!

    Yes, the alarm on the Std-Horizon 22xx can wake the dead. I send the AIS data to my chartplotter, which apparently cuts out the alarm on the VHF (or somehow I have it turned off). It's much easier to read the target data on the chartplotter and I can turn off its alarm if desired.

    Bob-

    Are you using an AIS transmitter, as well? Or just the AIS receiver of the Std-Horizon 22xx?

    Thanks,
    Todd

    I'm using the AIS receive-only via the VHF. I was planning to reinstall my stand-alone NASA "AIS Radar" (also receive-only) for Pacific Cup but with the AIS targets available through the chartplotter, I think that will be adequate. If anyone still needs an AIS receiver I'll sell the NASA unit pretty cheap to an SSS'er - a lot less than Amazon wants for one:

    Kudos to Todd for stepping up to a J/92S!

    I have Vesper Marine AIS transceiver (class B) on my boat.
    It is sharing masthead antenna with VHF radio using Vesper Marine VHF splitter.

    I am transmitting my position (as well as SOG and COG) and it gives me
    some sense of security -- I assume that other ships in the ocean will see
    if we are on collision course, even if don't see them.

    My data are:
    S/V Libra, MMSI: 367562690

    Thanks,
    Przemek
