I remember the notion but do not have a link, I think it was from Homeland Insecurity. One reason to have an AIS 'transmit off' switch like we installed with our
Garmin, a simple switch installed across two data leads as per Garmin's
installation instructions.
In our case with a
Garmin AIS600 the transmit function is automatically turned on as soon as the NMEA2000 network is powered live, ie whenever there is power to the network backbone NMEA2000 (which includes our windspeed/direction/boatspeed,
autopilot and
depth displays. Turning off the AIS on the MFD or even turning the display off totally has no effect on the signal transmitting which carries on regardless. This may be why some, even many do not even realise they are still transmitting when back in their marina slip. Plus there is a
phone App that automatically calls
Marine traffic via
email every 2 minutes or so if activated as I discovered when waiting for a meal and downloaded it, later to see my 'boat' on
Marine Traffic online had been travelling though town at 40mph as we drove home. It also explains why I have sometimes seen on marine traffic a 'target' travelling at 70+ mph northbound on I-95, likes somebody left their tx turned on in their trailered boat and going home to the frozen north.
My garmin has a physical TX on/off switch mounted at the nav table so if in pirate waters we can go silent if needs be or if leaving our
instruments on whilst at
anchor we will not 'bug' others
