Hi Barry,

I think you meant to say that you were _not_ able to plot ...

OK.

I agree that the WOUS64 bulletins seem to have the information needed.

>So it looks like the 08 Nov 2004 NOAAPORT message you found is correct

I make a quick hack to wwdisp.c to see if using the WOUS64 bulletins
would work:

      /* <<<<< UPC test mod 20050331 >>>>> */

      if( strncmp ((const char *) &text_header[7], "SLS",  3) == 0 ||
         (strncmp ((const char *) &text_header[4], "WWUS", 4) == 0 && 
text_header[5
] == 20) ||
         (strncmp ((const char *) &text_header[4], "WOUS", 4) == 0 && 
text_header[5
] == 64) ||
         (strncmp ((const char *) &text_header[4], "WWUS", 4) == 0 && 
text_header[5
] == 9))
      {

Comments?

Cheers,

Tom
