I think Charles meant the use of FSK-D.  That is the mode in the K3  
that takes paddles.

One tell tale sign should be the drunks appear to slow down when  
sending J and numbers and then speed up when they send letters like E  
and I.

Average CW speed is measured with the "standard" word PARIS, whose  
characters in Morse are all shorter than most numbers in Morse code.   
So, even if the op claims to paddle CW at "60 WPM," there is little  
chance they can send non-cut numbers at full RTTY speed.

If not for (ab)use of paddles, I can't think of what else can cause a  
K3 (in either FSK or AFSK) to sound differently from other rigs.
