Clint,

The reason for the 3 different sources is that the 3 top tier nodes feed
each other from their own satellites. It's a race condition on what source
a product will come from.  This is why the IDD is robust. This is good
because it shows all the system are operating, it doesn't mean you are
getting duplicates.  The only way a duplicate should show up at your site
is if a upstream site is receiving FOS and NOAAport. The products don't
match because the sequence numbers are different even though the rest of
the product is exactly the same, the ldm thinks they are different
products. I know this is confusing.
