Hi Daryl,

The textual data-products on the IDD are mostly from NOAAPORT, so whatever 
encoding the NWS uses will be the encoding on the IDD. This link might help: 
<http://www.nws.noaa.gov/tg/table.html>.

You got me. I know the LDM but not the data. I'll forward this to Tom.

I think, however, that data-products on the NOAAPORT textual channel are tagged 
IDS|DDPLUS and those on a particular, non-textual channel are tagged HDS.

You figured that out. :-)
