I asked Ofcom why my boat appears not to be in the ITU MARS database. They agree that my licences are correct and up-to-date. They are trying to ensure that my details are re-instated to the database. An e-mail reply from Ofcom today included the information that
"<span style="color:red">Due to customers now being able to apply online for Ships Radio licences this has caused the system to at times create duplicate call signs and MMSI numbers in our system. As you will fully understand this creates a major safety of life issue for all vessel owners ...</span>"
I think we should all search the ITU MARS database for our callsigns and MMSI numbers to ensure that (a) they are there and (b) are correct. Any problems should be reported to firstname.lastname@example.org.
