See my previous post on a group MMSI number. You have the magic BB. If we drop the 0 from the end of your number and add it at the beginning, it will make it a group MMSI. If you load that group MMSI into your radio, any C-Brat can just put in the group call, and your radio would respond. You don't have to know who is there, just that somebody in the group is there.
If my understanding is right, we could use 036697831 as the group call for the C-brats.
Maybe not quite like that, according to what I have read since I posted above. More from the same source:
A group MMSI _starts_ with a single 0, followed by the three-digit "country code".
Individual vessel MMSIs start with a non-zero digit, and the first three digits are the "country code".
Coast Station MMSIs start with two zeros, followed by the "country code".
If you wish to fabricate your own group MMSI (I'm not sure how legal that is, either here in Canada, or in the US), you'd add a leading zero, and drop one of the last six digits to make room for it, leaving the "country code" intact.
See the MMSI Webpage.
