Nautilus Lifeline Work In Coz?

Most of the other operators I know use channel 06. I believe 63 is exclusively an Aldora channel.

There are no exclusive channels. Aldora may be the only one using 63, but others could if they wanted.

ADDED:

International VHF Marine Radio Channels and Frequencies | Navigation Center

Agreed. I have perhaps hijacked it myself from time to time. I will neither confirm nor deny.

I checked this with an Icom technician in Melbourne Australia. Even if a radio is DSC capabable the DSC function is NOT enabled unless the radio is programmed with an MMSI it will not even receive DSC emergency signals

So the dive boat may have a DSC radio and have no DSC capability.
