Config choices for AIS MOB device

If you have an AIS MOB device, how have you configured it? I have my MMSI to plug into the device for the individual call, but am wondering what others have done for the group MMSI if in the US.

My thinking is to plug in the USCG ID 003669999; is there any reason I should use something else?

I'm setting up an OceanSignal MOB1, and the behavior varies based on country. The US includes the option to send a group call, but elsewhere an "all ships" distress alert can be sent:
  • USA: AIS + DSC Individual Distress Relay call plus group call sent after 30minutes
  • DE, NL, ES, GB: AIS + DSC Individual Distress Relay call only
  • ...
  • RoW: AIS + DSC Individual Distress Relay, All Ships Distress Alert, sent once on MOB1 activation and on manual initiation

Re: Config choices for AIS MOB device

If you can get an all ships DSC call from your unit, do so.

Unfortunately all the units I looked up offered an open AIS distress call ("AIS all ships"), but only a mother ship DSC mayday. This pisses me no end as we are again and again being sold things that are only 50% as good as they could be.
