20040923: dcwcn problem



Harry,

The 5.7.3 release notes from NCEP mention:

    I.  Fixed the WCN decoder DCWCN (SPC)

        It was noticed that the raw WCNs occasionally contained extra
        lines between the MND and the UGC line.  This line caused the
        decoder to hang.  These lines are now being skipped and there are
        extra checks for finding and validating the VTEC line.

I am preparing the release at this moment, and hopefully will have it
posted by tomorrow afternoon (but could provide a pre-release 
earlier if necessary- while still updating docs, pqact.conf entries,
tables, etc).
