Erasing MMSI number from DSC vhf

[prv]

On my new Icom I can turn the alarms off I believe.

You may be right, but I believe the DSC standard requires that it be impossible to disable them (obviously you can silence them after receipt). So most radios don't allow you to turn them off.

My Silva is easy to do, a few button presses, you can even program your own channels in to two private slots, 0 springs to mind.

You need to access the "service" menu, a bit like being administrator on your computer. There is some information on the net depending on the radio in question, although it is bad form, as the scrotes can access it and make yours more attractive to a potential buyer.
Your local competent boat electronics repair man should have access to the info required to reset the existing number.
Out of interest what make/model is it ? (just in case it's the same as mine!)

Mine on last boat a Standard Horizon was reprogrammed by the local electronic specialist after I cancelled our MMSI with USCG.. New owner later had the electronics man enter a new one.
