Can you give us some more info on tristate mode.  The man page mentions
using '-3' and "This option is effective only if ham_cutoff is
non-zereo.[sic]".

How is the unsure option returned in the X-Bogosity header and do I need to
set -o?  What's a good value for -o?

Questions, questions!

Thanks
Laurence
