Stephen,

The $GEMPAK/source/bridge/mt/mtgrpt.f routine is checking
for a bulletin type of 5 characters of "SPECI" or "METAR" in bullatins
that 
don't have a METAR, SPECI or MTR pil header line. Your product
does not match on those keywords.The LWIS case can be inserted in the
check and
the length modified accordingly for 4 characters in that case. I can
post a
test version of that routine modified for you to verify that no
unexpected side effects
are created.
