[CQ-Contest] The damn robot won

[Pete Smith]

I'm still hoping that one of the guys who was involved will tell us 
how the Skimmer number was arrived at, and particularly what 
validation level was used.  With 3 KHz of audio from a typical audio 
tape, Skimmer would "hear" much the same muddle as a human.  If a 
second signal appears on exactly (or close to) the same frequency, it 
gets as confused as we do.  But in any case, nobody is suggesting 
that a human mind can do what a properly implemented Skimmer can do, 
even in a 3 KHz bandwidth.
