Re: [Elecraft] K3 potentiometer dead spots?; Concentric Knob replacements

2009-10-28 Thread Eric Swartz - WA6HHQ, Elecraft
Four encoder knobs are warranted for life. A couple of months ago, probably after you received your replacements, we changed the knob formulation to include a 10% glass fiber fill, which makes them almost impossible to break. In testing them we actually ended up stripping the hex head without b

Thank you Don and all the rest that responded. Thanks for the correction too regarding encoder/potentiometer. Apologies for the snafu. I'll send Aptos an email and see if they can change those encoders out. It makes it difficult at times to finely tune whatever it is I'm trying to adjust in the

[Elecraft] K3 potentiometer dead spots?

2009-10-26 Thread James Sarte
