Not quite. DSC includes your MMSI but not your callsign, and won't switch other radios onto Ch16. It's still important for us to keep a listening watch on Ch16 (even if it's on dual watch
to prove a point with what is to me the best bit of dsc and the most important, the ability to switch other dsc radios to 16 no matter what channel they were listening on ...
last week working with an offshore installation, dsc distress call switched our dsc radio and all the other vessels working the job off our private vhf channel and onto ch16 in response. Too far away for us to be any assistance and we all switched straight back to the private channel to continue the difficult task in hand with radio comms between the boats. Unfortunately the marine controller on the installation was away at the time for a brew or loo break and missed the call but some kind office wallah who was passing muted the alarm!
When we used the phone to eventually get hold of control he pleaded guilty to having been unwittingly monitoring ch16 for quite a while and that he had been amazed how the boats were managing to co-ordinate the various bits of the task without apparently speaking on the radio.
