Re: 20050708: Manual decoding with dcwarn decoder?



I'm on A/L this week, but your answer makes perfect scence to me.  When
I ran dcwarn in verbose mode, I could tell that it could "see" the
product, but it was just unable to decode the warning.  In the back of
my mind, I was starting to wonder if it was a header issue.  When I
displayed raw NOAAPort text, it appeared to have some control characters
at the start of the product.  I had forgotten about the ZCZC...NNNN
structure.

Thanks!  I'll try this out next Monday.
