Can a DSC radio set-up a DSC call based on input to the radio via NMEA-0183 using a standard sentence?

Yes,
Icom radios such as the M504 can initiate a DSC call upon the
reception of the appropriate
NMEA 183 DSC sentence. It's a long time since I played with this but if I remember correctly something like
Code:
$CDDSC,20,503112090,00,00,26,900072900072,,,,,R*16
should initiate a
VHF DSC call to 503112090 on
VHF channel 72.
I'll leave it as an exercise for the reader to peruse Recommendation ITU-R M.493-15 to
work out how to send all ships calls, position requests, etc.
I should add however, that I have never dared to try to initiate a DSC
Distress call, for obvious reasons.
