I'm OK with it, but my encoder shaft does not appear to be free spinning. Keeping the knob away from the felt washer still shows drag. I'll give it some time. Probably OK as it is.

The optical encoder is quite "free-spinning", and if there is not enough friction, unexpected frequency changes can occur while with too much friction, tuning becomes cumbersome. The balance point in the middle is an individual decision, but I believe a totally free-wheeling encoder shaft will give you problem with unexpected frequency changes. In other words, put a bit of drag on it, but just how much is an individual decision - now that you know the pros and cons, accept the consequences of your decision point. This is *not* a problem to be fixed, it is an individual decision about how much drag should be on the VFO knob - as I have said, that is an individual decision. Use your best judgement. 73, Don W3FPR On 6/9/2012 8:56 PM, Joseph Trombino, Jr wrote: > My take on this is that there will be probably more home/portable users of the KX3 than those using it mobile in a car...in any event why not make the degree of friction adjustable by the user? > > I hate to have to grind away trying to turn a main tuning knob when operating...my K2 knob is adjustable along with the K3...is this friction a function of the optical encoder used??? > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
