The pqact I use is more specific than yours, but it shouldn't really matter.

# RTMA (real-time mesoscale analysis) Grid 227 CONUS 2km
NGRID    ^L.IA98 KWBR
    PIPE    decoders/dcgrib2 -m 200 -d data/gempak/logs/dcgrib2_rtma.log
    -e GEMTBL=/home/gempak/GEMPAK6.2.0/gempak/tables

greetings gembuds.
anybody else using dcgrib2 to convert the RTMA to gem?
looks as if there is an error in the header,
or I'm screwing something up
here is a snippet of the GDINFO

  GRID FILE: /usr/local/ldm/data/text/gempak/model/rtma/2011080604_rtma.gem

  GRID NAVIGATION:
      PROJECTION:          MER
      ANGLES:                 0.0     0.0     0.0
      GRID SIZE:          177 129
      LL CORNER:              16.83    -68.20
      UR CORNER:              19.75    -63.97

and in my LDM pqact.conf

NGRID   ^L...98 .... .*RTMA
         pipe    decoders/dc/dcgrib2
         -e GEMTBL=/usr/local/ldm/nawips/gempak/tables
         data/text/gempak/model/rtma/YYYYMMDDHH_rtma.gem

that is a horribly small area to map ...

anybody got suggestions ???
