I have trouble believing this statement.  It is well known from circuit
design engineering that a faster risetime or falltime creates a wider
bandwidth signal.  The risetime of the original K2 keying circuit was 3
milliseconds and the falltime was 2 milliseconds.  So how does a 3
millisecond risetime create more key clicks than a 2 millisecond falltime?
