Re: 20000322: IDD feed contents (fwd)

This is very interesting, Chad. I think the problem is that the
MRF MOS bulletins have binary RS characters (ascii 30) in them which
bound the information for each MOS site. I just looked at the MRF MOS
bulletins that came over HDS and each one has more than 3 of these,
so that would explain it. This is not isolated to just MRF MOS
either, the NGM MOS bulletins have these characters as well. And I
remember that the old SA reports were bounded by RS characters, although
it doesn't look like they do that for METARS.

I think the solution would be to add RS as a "printable" character.

thanks for your help,
