little update folks, i managed to get the original MMSI number put into my name fairly easily.
couple of things you need from the original owner are the MMSI, call sign, name and address. if you struggle with any of that you can call ofcom and they will ask some questions re the original owner to confirm you own the equipment legally and can assist with mmsi, call sign etc. if you have those 2 it can be registered against your name on the ofcom licencing website.
thanks for help channel ribs-appreciated.
