It is most likely that the encoder must be replaced to correct that behavior.

The VFO B encoder is a thru-hole part and can be replaced if you have good de-soldering tools and work very carefully so you do not damage anything else around it or damage the board or the SMD parts that are in close proximity to the encoder solder pads. Reverse the steps in the assembly manual to tell you how to get to the encoder and front panel board. Make careful note of the screw size and length in each place you remove a screw.

If doing that gives you pause, then let the techs at Elecraft handle it for you - it will be worth the price. Contact support to initiate the RSA process. If you just want to purchase the encoder and do it yourself, you can contact [email protected] directly.

Hi all,

Just received a used KX3 today and found that VFO B is skipping. Lets say
the top number is rotation out of 9 and bottom number is actual sensed
position, it kinda does this>
