Rodney,

The pqact entries are attached to this email. Here's a sample entry:

# ETA model on Lambert conformal CONUS grid
HRS     ^Y.Q... KWB. (..)(..).*/mETA
        PIPE    /usr/local/ldm/decoders/gribtonc
        etc/eta_211.cdl
        data/pub/decoded/netcdf/GRIB/(\1:yyyy)(\1:mm)\1\2_eta_211.nc

These entries are for the decoders-3.0.2 version of the decoders package.
If you are using a older version, I suggest that you download and install
the new version.

If the cdl is not included in the package, you can create the cdl using
the gribtocdl program that's included in the decoders package. There's a
man  page for the details. Here's a few hints on using gribtocdl:
- concatinate products into one file to represent all the variables you
  want in the output netCDF file
- gribtocdl only produces a starting point for the cdl file, you have to
  edit the cdl to get the desired results, ie adding vars, times, etc

To test decoding with error messages output to screen:

% gribtonc -l - file.cdl file.nc < rawGribFile
