[Elecraft] K3 AF Volume Surprises

[John Watkins]

Came into shack and hit the power switch on the K3, rig fired up and had room filling audio.  So I grabbed the AF knob to turn it down some and found it was already counter clockwise to the stop.  After rotating it some it appears to have a spot just off the bottom that is pretty loud, like where it should be at 11 o'clock position.  Suggestions?  Maybe it is mad because I have been using the KX3 too much ;-)
