Bryan,
>FYI...I am guessing this means that Jan 1, 2001 is now a firm date for the
>start of unencrypted radar products.
Yup.
>Unfortunately, this message doesn't have any details on what will change (if
>anything) in the NWSTG stream.
In general? The change is that the NIDS products will stop being encrypted
and will start being compressed using zlib.
I will be adding zlib uncompression to my NIDS server at the end of
November. I should then be ready to go.
>I am assuming that they will turn of encryption on 1/1/2001,
Yes.
>but as usual, details are scarce with the NWS.
They do have this information on one of their web pages somewhere.
