David,

Lyle will give you his observations, I'm sure, but I thought I'd 
mention that I've been able to copy some pretty sloppy code with it. 
The decoder keeps track of dot/dash ratios, factors out noise to the 
extent possible, and now also has an "AUTO" mode where it will try to 
select the ideal signal level for element vs. space decisions. I'm also 
planning to do additional analysis of element vs. letter vs. word space 
lengths, at which point it should handle very individualist sending.
