Mike,

Your NOAAPORT ingestor should not try to wrap the GINI products
with FOS bulletin delimeters. The products that NCEP uses do not have FOS 
delimeters, so GEMPAK is not expecting them. Our Unidata NOAAport ingestor 
places the GINI products in the NIMAGE stream and not under the WMO (aka HRS, 
IDS, DDPLUS)
streams and does not add FOS data stream delimeters.

However, given that you do have FOS delimeters being added, you can simply PIPE 
your data through from the LDM through a script that uses the "tail" command 
rather 
than FILE'ing the data such as:
 #!/bin/csh -f

if ($#argv < 1 ) then
   echo "Usage: $0 outfile"
   cat >/dev/null
else
   cat | tail -n +3 > $1
endif

exit 0

In the above, the "-n +3" syntax is the gnu tail syntax. If you have another 
version
of tail, then simply "+3" to start at line 3.
