HiI have one of the weighted CNC knows on my K3. I've had it for about 3 Years. I rarely tune the radio with the know using mostly software. However now a days when I do turn the knob there is a very pronounced dead spot, and a notch in the turning of the knob. The weight of the knob has permanently altered the feel of the encoder and I fear it will need to be replaced one day.Because of this, I do not recommend weighted knows on a k3. Perhaps if you use it every day it would be different. But if you mostly just let it sit my experience is that it will permanently damage the encoder over time.73 Tom va2fsq.com

If the K2 was built quite recently (or has had the encoder changed to the new one), then the K3 knob(s) will fit. I would suggest the K3 VFO B knob for those newer K2s - the VFO A knob is too large and its diameter interferes with the display plastic. You would have to add substantial thickness to the felt washer to provide a bit of drag on the knob. Know that the K2 knob is weighted, but its weight is not as heavy as the CNC knobs that have been offered. My gut feeling is that one reason that those heavy knobs are used is to allow giving the knob a spin to make large QSY excursions. The problem with that is with a free-spinning knob, the knob may move after it is stopped, so the frequency you thought you stopped at will be changed when you lift your fingers from the knob. I have had several K2s sent to me for repair that had no drag on the knob, and part of the reason for sending the K2 for repair was that "the K2 drifts". There must be some drag on the knob if this "drift" is to be avoided. Lastly, if you install a heavy knob and then ship your radio for any reason, you should remove the knob to assure that the encoder shaft will not be damaged during shipment. 73, Don W3FPR On 1/17/2017 6:11 PM, Niel Skousen wrote: > Has anyone used the K3s knob on a K2 ? > > Does it fit, how do you like it ?? > ______________________________________________________________ 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 Message delivered to [email protected] ______________________________________________________________ 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 Message delivered to [email protected]
