    I have a program which will insert the name information on line 0
    of each TLE, converting the file from 2-line format to 3-line
    format.  If this would solve your dilemma, I'd be happy to send
    it to you.  The only caveat is that it requires you to keep a
    text file called SATNAMES.DAT up-to-date as you learn the names
    of newly launched satellites.  The file format is pretty obvious.

    This is a GZIP file (similar to a ZIP file).  The DOS command for
    unzipping it is:
    >  gzip -ad <filename>
    If you don't have the GZIP program, you can download it off the
    web I'm sure.
