Art,

With NOAAport now, AVN is comming in on more projections.
You have 3 different grid projections there in the
error message below, and all the data in a single GEMPAK 
file has to be the same projection.

The error message is saying that the grid being decoded does not
match the projection of the grid file.

You need to modify your pqact to either use the @@@ template in dcgrib
so that the grid projection number is used in the file name, so that
you don't have conflicts such as this:
        YYMMDDHH_avn@@@.gem

Or, modify your pqact pattern to be more exact in the pattern, if
you only want one of the projections-
eg instead of:
^Y.*/m(AVN|SSIAVN)

use
#
# AVN model output
# Grid #201 N. Hemisphere 381km: ^Y.A... KWBC.*(/mAVN|/mSSIAVN)
# Grid #202 CONUS         190km: ^Y.I... KWBC.*(/mAVN|/mSSIAVN)
# Grid #203 Alaska        190km: ^Y.J... KWBC.*(/mAVN|/mSSIAVN)
# Grid #211 CONUS          80km: ^Y.Q... KWBC.*(/mAVN|/mSSIAVN)
# Grid #213 CONUS          95km: ^Y.H... KWBC.*(/mAVN|/mSSIAVN)
# Select grid desired from [QAIJH]
HRS     ^[YZ].[Q]... KWB. ([0-3][0-9])([0-2][0-9]).*(/mAVN|/mSSIAVN)

I'll update the gempak WWW pages with the pqact.conf information
for the new NOAAport grids.
