But I can see why some people would fail to use it.
It seems straight forward, but programing the radio is not always easy, getting the MMSI number was not easy. And above all I can well see how people in a difficult situation would want to resort to old fashion methods that they are familliar with.
I was furstrated in getting my MMSI number, Im still reading the instruction book that came with my radio and of course, apart from the VHF course I did, I havent practiced using the RED button.
Oh, and connecting the Radio to the Plotter was not that easy.
I have seen a thread about some DSC red buttons requireing different methods of operation - which is daft. I should be: Open flap, press, hold for x seconds, shout Mayday, abandon ship.
However, its still a good idea to have one. Id just like to spend an hour with someone with the same radio as mine to show me how it all works
