Patrick,

I believe your problem is related to the fact that I added the NET grid a while 
back
as you recall. The pqact.gempak_decoders pattern action has the -close flag, and
so what ends up happening is 2 copies of dcgrib2 are running simultaneously and 
writing
to the same output file (one decoding N0R andthe other decoding NET). The 
result is
a corrupted grid file.You should be able to improve your plots by changing the 
-close
flag in the pqact action to -flush as:

# National radar composite generated by GDRADR for IDD
FNEXRAD ^radar_mosaic_national
        PIPE    -flush  decoders/dcgrib2 -v 2 -d 
data/gempak/logs/dcgrib2_radar.log
        -e GEMTBL=/home/gempak/NAWIPS/gempak/tables
        data/gempak/radar/YYYYMMDD_radr.gem
