HIYA!

I have my LDM email me RERs and other interesting text products.  Anyway, 
it seems that lately I have been getting many duplicate emails.  The text 
of the products will be the same but the WMO header will be slightly 
different.  Take, for instance, a SPECIAL NCEP DISCUSSION  ADMNFD

If you look at the product sizes, there are two pairs that are identical.  
And there are two products that don't appear to be duplicated.

I dumped two of the products with the same size to a file and diffed them.

# diff one.txt two.txt
1,2c1,2
< 019 
< NOUS42 KWNO 101740

Hmmmmmmmmmm.  Anybody else noticed this?  I have checked a colleagues LDM 
and he has the same duplicate products.  I also seem to think that other 
products are being duplicated as well, but I can't find evidence of it 
right now.  Maybe it is just something unique about KWNO  or I am 
imagining things.

Since AWIPS is probably generating the header, maybe there is a problem 
there this morning.  Anyway....

Thanks,
  Daryl
