Larry and Pascal:

Isn't the momentum for DSC and GMDSS being driven by European
requirements? My understanding is that implementation by the UK and
other European coast guard stations is farther along than in the US.
Manufacturers tend to build to meet the market's most stringent
requirements.

Very good opinion. I do not understand why Garmin, Raymarine and Icom,
for example continue to invest in DSC; the "new" DSC Position Report
feature of Garmin GpsMap 276C for example, wich demandas a VHF Radio
with NMEA IN and OUT, is ridiculous. These manufacturers should
instead take attention to AIS insted this "half-assed" DSC technology.

True, in Europe all coastguard stations have the equipment, and so do
all IMO registered ships. They are checked when they get to port.

Manufacturers tend to build to meet the market's most stringent
requirements.

The IMO is a worldwide organization, and it has mandated GMDSS, of which
DSC is a part. As of February 2005 no coastguard in the world nor any
vessel is _obliged_ to listen to Channel 16. They may do so however, and
this is done even in Europe.

From the UK MCA website:
http://www.mcga.gov.uk/c4mca/mcga-gu...comms_code.htm

"While the United Kingdom Coastguard will continue coverage of VHF
Channel 16 for the foreseeable future, from 1 February 2005, the
Coastguard watch on Channel 16 will be downgraded from a dedicated
headset watch to a loudspeaker watch. Also, from this date, ships that
are currently obliged to keep a listening watch on Channel 16 where
practicable, will no longer be obliged to do so."

And the Dutch coastguard says:
http://www.kustwacht.nl/Engels/Newsl...37E%20LW16.pdf

"It is therefore that the Directorate-General Freight Transport of the
Ministry of Transport and Public Works decided to continue the radio
watch on VHF channel 16 in The Netherlands, for the time being for an
unlimited period, after February 1st 2005. The decision of other
countries in this matter is unknown.
In spite of the above-mentioned decision The Netherlands Coastguard
maintains its advice to seagoing yachtsmen to change over to GMDSS
equipment. It is in their best interest to initiate alerts on VHF DSC
channel 70 whenever the circumstances require doing so. Only in this way
one stands a very good chance to be “heard”."

In follow-up, read this: http://www.navcen.uscg.gov/marcomms/gmdss/dsc.htm

"The USCG plan to implement GMDSS Sea Area A1 is one element of the USCG
National Distress and Response System Modernization Project, now called
"Rescue 21", which replaces the whole USCG VHF distress system. On 24
September 2002, Secretary of Transportation Norman Mineta announced the
award of this $612 million contract to General Dynamics Corp.

Until this system is installed, the Coast Guard cannot reliably receive
VHF DSC distress calls."

Guess 3 1/2 years is not enough time for the US government and General
Dynamics to install radio transmitters with DSC ...
