Arne,

Yes, I also suspect the encoder has gone bad.
You can replace it yourself if you have de-soldering capability. If not, your K3 will have to go back to Elecraft. Contact [email protected] to order the encoder, or if you prefer to send it in for repair, contact [email protected] to request an RSA.

Hello,

The CMP/PWR-Control on my K3 has ceased working. I can switch between the
two functions by tapping the knob and the present setting of Compression and
Power respectively shows up shortly on the display. But nothing happens when
turning the knob and I am stuck with the present settings. I have updated
the firmware (MCU=5.60) and run the TX Gain calibration. But the problem
with the CMP/PWR-Control remains and I suspect that the encoder has
developed a fault. Suggestions?
