I have not seen the PS info but much info in this thread is wrong. I invite you to look at the Cruisers Forum section on Engineering Systems->Electronics. There at the top in a stickie you will find lots of good (and correct) information about SSB emergency use. It is wrong to say that no one monitors. There are many monitoring but they do it automatically and your SSB radio needs to be DSC equipped for the best chance at being heard.
