You do not need to use any decoder since GEMPAK (from Unidata at least) can
display these products directly (as can McIDAS).

Here is the action we use to file the NNEXRAD products:
NNEXRAD ^SDUS5. .... ([0-3][0-9])([0-2][0-9])([0-6][0-9]).*/p(...)(...)
FILE -close data/gempak/nexrad/NIDS/\6/\5/\5_(\2:yyyy)(\2:mm)\2_\3\4
