The plotter is not involved in the issue.
The vhf is an M Tech that I bought from Compas 24 so it looks like I wil have to return it to them to have the MMSI erased. I presume that they will install a new MMSI which I then have to register with offcom.
What sort of cost is involved in having the MMSI changed?
