In the real-time data stream you will find sequences beginning with ^A \r \r \n and the product ends with \r \r \n ^C or ZCZC and ending with NNNN If your archived data has these characaters stripped out, then you would have to recreate them, such as is described in: http://www.unidata.ucar.edu/projects/coohl/mhonarc/MailArchives/gempak/msg03578.html See if your data looks like that described in the archived message above, and if so, add the ZCZC and NNNN sequences as described.
