The K3's VFO encoder shaft has bearings that allow it to freewheel. The KX3's doesn't have these. I doubt this will change.
With a portable transceiver, it's better if the VFO stays where it's put. This attribute also assists in mobile ops with a lot more lumps and bumps to the VFO. 73, matt W6NIA KX3 #6 FT On Sat, 09 Jun 2012 19:59:02 -0700, you wrote: >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.
