Jim, I cannot say for certain because I have not seen the knob. I do have a concern for knobs that are heavy and do not fit properly against the felt washer. For one thing, the heavier knob spaced out from the front panel will put extra downward stress on the encoder shaft - that is canceled out if the new knob is in full contact with the felt washer. A bent encoder shaft will create binds when tuning. Secondly, a knob with no slight friction will allow the VFO to drift when you tap on the operating table or just "breathe" on the knob. You must have some friction on the knob for the VFO to be stable.
So bottom line, if the new knob makes contact with the felt washer, it should be fine, but if it does not, be aware of the consequences. If that knob does not work properly for you, a 'finger dimple' can be ordered from Elecraft, and a rubber tire from the Yaesu FT100, FT900, or (I believe) the FT847 (possibly others) can be stretched to fit over the stock K2 knob to reduce the "pain" from the sharp front edge of the K2 knob. 73, Don W3FPR On 5/26/2011 6:59 PM, Jim Lowman wrote: > I've searched through the archives provided by Leigh, and found that > various replacement tuning knobs for the K2 work well. > Among others, the FT-100. > > I have a heavier-duty metal knob that I bought from Ten-Tec as a > replacement for the knob on the Argonaut V, but traded that radio in to > Ten-Tec toward an Eagle before I could install it. > > This knob is no lightweight, but has the finger dimple. > > Any problems with replacing the stock K2 tuning knob with this one? > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
