Mike,

The $GEMTBL/grid/grdnav.tbl has an entry at the bottom for
GG01 703 that is identical to the grid 3 at the top of the file, and dcgrib2 is 
using that
as the number (loading the table last in first out). Place a "!" character
at the beginning of the 703 line to avoid using that. I don't know why NCEP has
that identical projection information in their table.
