Hongming,

Two things: first, the feed type should be capitalized. Second, WMO is a
mnemoic for several feed types (i.e., it is a compound feed type).  WMO is
the same as the combination of IDS|DDPLUS (a single stream) and HRS.
Since the lightning data is binary, what you really want is:

exec    "pqing -f HRS /tmp/jmb.fifo.2"

>                     FILE    /home/ldm/incoming/US\2\1

And this would then change to:

HRS     ^SFUS(..) (....)  .*
        FILE    /home/ldm/incoming/US\2\1

Beware of which white space is tabs and that no white space can
occur before the feed type:

- no white space before HRS
- tab between HRS and ^SFUS
- tab before FILE
- tab between FILE and /home/ldm/...

Also the trailing '.*' on the pattern is not necessary since it is
redundant.

I would make the changes I indicate above.  The other thing I would
do is use the LDM 'notifyme' command to see if/when the products
are received:

notifyme -vl- -f ANY -o 3600 -p SFUS41

I just did this on an LDM we have setup to ingest the HRS data
from a NOAAPORT SDI, and I see lots of SFUS41 products:

% notifyme -vl- -f ANY -o 3600 -p SFUS41

Your system administrator is correct.

Please let me know if the above helped.
