I agree, visually decoded CW is NOT a machine mode; the final decoding
being done by the operator eye-brain, instaead of ear-brain. 

I found it fascinating for that reason; you have to add some operator skill.

BPSK is a real machine mode; somebody talks about having a large bell calling
him when AFRICA locks on a signal. I see no interest in this, except for
propagation studies. A QSO obtained trying day after day, by previous schedule
and so on, is more rewarding to me.
