Keith,
Check out http://www.navcen.uscg.gov/marcomms/gmdss/dsc.htm. It goes
into great detail about DSC on MF/HF and VHF.
In a nutshell, it is a digital mode that allows you to signal for help
without picking up the mic. It sends out your vessel, callsign, and
location (GPS required). You can also selectively call another station
without disturbing the world. DSC radios will monitor the DSC emergency
channel constantly, even while you are on a different channel.
This technology will replace the regular radios by 2006 I believe.
Commercial vessels have already changed over, I think, or are doing dual
monitoring. But, eventually they will not be required to monitor VHF 16
or 2182kHz as they used to.
