[Elecraft] RF/SQL dual control

[efortner]

I don't know what changed but the dual RF/SQL control for main and sub
receiver cuts out at approximately 1 o-clock position just like a wiper not
making contact on a carbon pot for about

1/8 inch movement of either the large or small knob. The radio is only
several months old and I don't think the control is the problem. Any Ideas.
Radio K3s serial number 10326
