First, verify that you're receiving the data that you want
to process.  Use the command "pqcat -vl- -f ... -p ... >/dev/null"
to list data-products from the product-queue that match 
your "pqact.conf" entries.  For example:

pqcat -vl- -f NEXRD2 -p '^L2-BZIP2/(KTLH)' >/dev/null

and

pqcat -vl- -f NEXRD2 -p 
'^L2-([^/]*)/(KMOB)/([0-9][0-9][0-9][0-9][0-1][0-9][0-3][0-9][0-2][0-9][0-5][0-9][0-9][0-9])'
 >/dev/null

Verify from the listing that such data-products were received
*after* you made the changes to the pqact(1) configuration-file.
