[Elecraft] K3 HEAVY Knobs ???

[Rick Dettinger]

In my case, I don't like the heavier knobs so that I can spin them.  I  
don't think that I have done that since the mid 1950's, when we got  
chased out of C&G Electronics in Tacoma for seeing who could spin the  
slide rule knobs hard enough to move the pointer all the way across  
the dial!  Instead, I like the "feel" of the heavier knobs.  It is  
easier to stop at just the right spot, and when the fingers move away  
from the knob it is more likely not to move.  A moment of inertia  
thing.  Probably, the more finger coordination, the less this  
matters.  But, I did find that it was easier to tune my K1 with 150  
Khz tuning range when I installed a K2 knob, reamed to 1/4 inch shaft  
size.
