HI Tiffany - regarding your comment "if the file was named LIGHTNING, it won't 
match the pqact entry you have above because that is looking for USPLN1EX.",
just to be sure, I think you saw this at the bottom of our previous email, but 
we tried also with the file named USPLN1EX (no header in the file too) and got 
the same result.

This is why we are a bit stumped. Here are answers to your questions and we 
found an interesting potential cause (see bottom of the email).

So interestingly looking at the /awips2/data_store/lightning directory there 
are a bunch of files in here (we had not bothered to look here because in CAVE 
the USPLN and NLDN menu items show null time stamps and because of the entries 
we see in the unrecognized files log we just assumed it wasn’t being stored - 
but it is). And these all are text files.

Here are the entries in pqact.conf with the feedtype LIGHTNING

# USPLN
LIGHTNING USPLN1EX
FILE -close -edex /awips2/data_store/lightning/%Y%m%d%H%M.uspln

# NLDN
LIGHTNING LIGHTNING
FILE -close -edex /awips2/data_store/lightning/%Y%m%d%H%M.nldn


We also noticed in pqact.conf there is comment which may be a key... #USPLN1EX 
and LIGHTNING feeds are disabled in ldmd.conf by default
And indeed in /awips2/ ldmd.conf we see two lines commented out
#REQUEST LIGHTNING ".*" idd.unidata.ucar.edu # USPLN
#REQUEST LIGHTNING ".*" striker.atmos.albany.edu # NLDN

Is this perhaps why the data is being stored but not processed so it can be 
rendered by CAVE?
