Matt,

Here's the pqact entry UPC uses, note the white space are tabs.  For your
entry, I noticed *'s in the entry.  A way to test the entries is to cd to
LDMHOME and copy the entry onto the command line, redirecting the STDIN
from the raw input file.

Robb...

# upper air perl decoder
DDS|IDS ^U[ABDEFGHIJKLMPQRSTXZ].... .... ([0-3][0-9])
        PIPE    /usr/local/ldm/decoders/ua2nc
                etc/raob.cdl
                data/decoded
                (\1:yy)(\1:mm)

There are more examples in the README.perlDecoders file with the
distribution.
