[Elecraft] Analysis of a CW COMMUNICATION

[David Gilbert]

I don't care what you say ... higher speed does not necessarily 
translate to better communication.  In fact, as I demonstrated here* and 
as countless 160m ops will attest, lower speed is typically more 
intelligible under conditions of low S/N ratio:

And as others here have said, you dramatically cut down your pool of 
likely respondents if you insist on operating above 45 WPM in a contest, 
and if you're sending your call three times in a row in a pileup you're 
just an unnecessary part of the QRM.
