Hi Dave, Check out the K2 manual, page 32, right hand column. Sounds like you need to loosen the set screws on the knob and push it in a bit tighter against the felt washer and then retighten the set screws. The felt washer acts as a friction brake and the amount of "braking force" depends on how much pressure is applied between the knob and the felt pad.
I've found that a mobile rig that I have which may have a similar construction the knob spins much more freely during hot summertime temperatures while in the winter it seems quite a bit more stiff. 73, Mark, NK8Q K2 #4786 >From: Dave Sublette <[EMAIL PROTECTED]> >Date: Wed Jan 04 08:39:25 CST 2006 >To: Elecraft <elecraft@mailman.qth.net> >Subject: [Elecraft] Haunted K2 >If this is a duplicate, I appologize, but I posted it 18 hours ago and >it hasn't appeared.
