James,

dcsynop was a program I provided before NCEP started providing 
a synoptic decoder. The default synoptic station table that
the NCEP dclsfc decoder uses is lsfstns.tbl.

The lsfstns.tbl as provided by NCEP does not have the Japaneese
or Korean stations in it. The syworld.tbl that I provided does 
have them.

You could specify -s syworld.tbl. I have not updated the syworld.tbl 
with the additional stations that NCEP has in lsfstns.tbl though.
You could also  cut out the JP and KO stations from syworld.tbl
and add them to lsfstns.tbl.

I will provide an updated/merged syworld.tbl file with 5.6.E.
