Re: Can't change MMSI # in handheld with DSC????

Should a handheld be assigned to a vessel or a person? For the relatively rare case of a personal handheld that moves from boat to boat I don't see the point in changing the MMSI to match the boat of the day. If someone wants to reach you they will know your MMSI but not the boat you are on (unless you tell everyone you know each time you rewrite the MMSI but your friend list will shrink I suspect). If someone wants to reach the boat they will know the MMSI of the boat and it's radio will be sufficient. The contact info in the registry should also be updated if you use a different MMSI so that creates a huge logistics problem and may be the main reason regulators don't want users editing the MMSI.

I think the desire to edit MMSI numbers will go away once the whole concept of DSC as a system is understood. There is more to it than just what vessel you are on.

My good deed for the day
If there are any Uniden experts out there that would like to do a similar good deed. Please chime in. If you prefer not to make the secret handshake fully public, feel free to send me a private message.

Until the day that the DSC system is updated to some scheme like transmitterdan just suggested, I think that swapping numbers would still be my most desirable option. If the system were changed to recomend that handhelds be registered to a person, rather than a vessel, that would be an even better solution for me.

Re: Can't change MMSI # in handheld with DSC????

Since Furuno seems a little more loose lipped with the secret code, I looked into getting a Furuno handheld. Sadly, I only see fixed mount radios in their VHF selection.

This was a discussion item at the latest USCG GMDSS Task Force meeting. Doesn't help the OP, but relief should be coming at normal bureaucratic speed.

Thank you for posting. It is good to hear that a solution is in the works, even if I have to wait for it.

Re: Can't change MMSI # in handheld with DSC????

Been there refused to pay Standard. You might want to just access the MMSI data base and change the information there. Don't bother trying to change the number, Change the information associated with that number. That's what I did.

Good Luck & fair winds.

Re: Can't change MMSI # in handheld with DSC????

I have a related question to this. We recently sold our Lagoon 380 and although the new owner has changes the transmit details for the AIS, it still uses the original MMSI #. This name was changed in the AIS transmitter on board, but it still comes up as Sephina on marine traffic and vessel finder.
SEPHINA - Sailing vessel - Details and current position MMSI 503654800
I would have thought they would recieive vessel information via base stations and automatically update vessel details. Any Ideas where they are getting their information and how to update the data?
Thanks
Monte

Your post is missing three key bits of info that determine the way to go.... Who issued the MMSI number (national radio authority or BoatUS?)? Where was the boat registered/documented before and after the sale? Was the registration number maintained after the sale?

In any event, those sites get the boat name from the official databases (probably via the ITU database that can only be amended by national authorities; I wonder how they handle the numbers issued by BoatUS).

You should go back to the authority that issued the MMSI to you and follow their process to terminate the MMSI or change the boat/owner details, whichever is the right way to go.

Thanks Charlie
Vessel MMSI was registered in Australia
Now registered in BVI's
I will contact AMSA/Ausbeacons and check with them about changing the details

Here is my 1 cent..

Assuming that Oz and BVI handle these things as UK and most other former colonies (excluding the US):

- You have to terminate the boat's VHF (and HF) radio licenses, call sign and MMSI(not "change details") in Australia

- New owner has to apply for new BVI radio licenses call sign and MMSI.

- The new MMSI and call signs will be different than the old ones because the call signs and MMSI numbers are linked to the registration country that has used them.

- It is illegal for the new owner to keep broadcasting the old MMSI via AIS or DSC radios, hence he/she needs to change the numbers in the radios and AIS transponder. Neither Oz nor BVI will assume responsibility for how difficult they have made this.

If you can share the model of AIS and radios we can see if anyone can share the recipe for the MMSI change....

Charlie

A breath of fresh air.

KISS

If you want to move your HH, get one without DSC. Lots simpler. Or just move it and forget it for DSC, and check if the vessel has one and it is properly registered.
