I also found Keith's comment re FT8 vs CW surprising.  This has certainly
not been my experience.  Altho the FT8 decoder in rc2 is not as good as
JT65's, it's a lot better than my ears.  I've seem multiple decodes when I
could not even hear the presence of the signal.  In addition, FT8 does a
much better job of decoding multiple signals than my ears can do. I've seen
decodes of two signal where the difference is less than 10hzs.  I realize
some operators can "decode" multiple signals in a passband a lot better
than I can however.
