[Elecraft] K3 tuning knob wear

[Eric Swartz - WA6HHQ, Elecraft]

Hi Kieth,

Looks like you have a very early K3. In later runs of the main K3 tuning 
knob we added a small radius to the transition between the dimple edge 
and the front face of the knob that removes the sharp machined 90 degree 
edge. (A 90 degree transition makes it harder for the powder coat to 
adhere to the surface, especially if one's finger nail regularly drags 
across this transition while tuning.)

Contact parts at elecraft.com and they will get you a new knob under warranty.

73, Eric  WA6HHQ
