[Elecraft] K1 - Can someone quantify "faint wiper noise" from VFO pot?

[Rick Dettinger]

A few years ago, someone on this list recommended a metal body pot.  I  
bought one and think it was a good investment for my K1.  I no longer  
have the original plastic model, or I can't find it, so I can't do a  
direct comparison, but the "metal" replacement has a very nice feel.   
I also use a heavier K2 knob on my K1, which likely helps in the  
smoothness department.
