Yeah, it introduces a degree and level of complexity which is bound to confuse things. For the operator. For the Coast Guard. For other boats.
Some see DSC as a blessing. I'm not a fancier, since I doubt if ANYONE out there will have the same understanding as others. Multiple users of complex systems not having a common understanding is a recipe for disaster.
It needn't be so messy, but it is. Mixed signals from ITU, local jurisdictions, manufacturers, users, and "testers". Clearly, from the video even the USCG has only a foggy notion -- mostly incorrect -- of DSC operation.
Even the MMSI number itself isn't inviolable: the U.S.-only MMSI number issued by Boat U.S. and by others is different from and not as useful as the FCC-issued MMSI number recognized by the ITU. Now, the UK is joining the mess. What a clusterf..k (to use a technical military term).
Basically, DSC is just like the SELCALL system used by aircraft. That system works very well. If only the basic DSC function(s) were used -- at least in the beginning until everyone understands and is comfortable with the system -- it mightn't be so misunderstood.
Let's see now, how do I initiate or respond to a 'group call' ?
