My MMSI is being received by other vessels
but my vessel name is not shown on their
chart plotter or PC
Some older AIS devices and chart plotters do not process the specific class B
AIS message which provides the vessel name (message 24). This is not a
fault of your AIS transceiver. Software upgrades are available for many older
chart plotters which will correct this issue. The other vessel should update its
AIS unit and/or chart plotting software to receive AIS message 24.
