And CW that is not perfectly sent will give most any CW decoder "fits".
The best CW decoder is the human brain, it is more tolerant of 
imperfections in timing and band conditions than any other decoder.

I just tried the K3 decoder on a W1AW bulletin broadcast, and with the 
QRN on the 40 meter band, copy was not perfect, but it was reasonable.  
My head could fill in the blanks easily.
