[GEMPAK #VOB-641611]: getting satellite images

Just found the problem: a difficult to see syntax error in the pqact entry for 
satellite images:

NIMAGE ^satz/ch[0-9]/.*/(.*)/([12]][0-9])([0-9][0-9])([01][0-9])([0-3][0-9]) ...

notice [12]] instead of [12]

I fixed this on your machine and re-read the pqact file "ldmadmin pqactHUP" and 
now see satellite images being filed away in /data/ldm/gempak/images/sat/

some notes:

* you'll probably want to remove the empty directories 
/data/ldm/gempak/images/sat/ch1/ and ch2/

* in your pqact.conf there are entries for NDLN, WSI, DDS|IDS, HDS and HRS.  
there won't be ingested and processed as long as your ldmd.conf entry only 
specifies the NIMAGE feed.

* you may want to direct /home/ldm/data to /data/ldm with a symbolic link, 
though how you have things set up currently will work just fine.

* I noticed you have GEMPAK 5.11.1 installed.  have you considered upgrading to 
6.2.0? for 32bit linux the install is straightforward.
