Hello all, picked up a new KX3 yesterday from my local emporium, slightly
annoyed by the awful noise the VFO knob makes rubbing on the felt washer to
provide the spin resistance, so I came up with a mod to improve this
dramatically.
Find a section of the clear plastic sheet that is used as mobile phone
screen protector material, draw round the felt washer on the plastic so you
are basically making a new washer the same size. Cut out the washer from the
plastic.
Place the felt washer back on the VFO shaft as the build instructions show,
place the new plastic washer on top of the felt washer, then re-fit the VFO
knob. Adjust to your choice of resistance.
I now have a VFO knob that feels very similar to my other radios and most
important, no rubbing noise, its almost silent.
