Tim,
can you explain that site?  Do I understand correctly
that the listed parameters are the UI-DIGI defaults and
that your receommendations are in the text added to
each parameter?

If the shown values are the "defaults" we need to get
the author of UI-DIGI to change some of them.  
(having WIDE7-7 as a default is a travesty...)

Im half way thoruogh reading them, but I may want to 
work with you on some of them...

Bob

Hey Bob,

I documented some of the settings and their effect at this site:
