Since touching the VFO knob causes the problem while touching the case does not, I suspect your VFO encoder is not grounded to the front panel sheet metal.
You can check with an ohmmeter if you're not adverse to removing the VFO A knob*. Put one probe on the metal shaft of the encoder and the other on a bare metal chassis ground point such as the knurled nut on the PHONES jack. If it's not nearly a dead short, there's a grounding problem. If the circuit is open, suggest you post a query to k3support at elecraft dot com. *The knob comes off easily. First slide the rubber "tire" off (get your finger nails behind the edge nearest the front panel and work it off toward you). Then you'll find set screw holes under the tire. A wrench came with your K3 that will loosen the screws. When you put it back together, the usual approach to getting the tension against the felt washers behind the knob right is to stand the K3 on its back panel and set the knob onto the encoder shaft. The weight of the knob usually produces the right amount of friction. Ron AC7AC -----Original Message----- What can I do to eliminate the static electricity problem with K3? Every time I touch the main VFO (A) knob the display goes dark, audio goes off, frequency changes among other things. After about 5 seconds it recovers but somewhat off frequency. Just a little foot shuffling will develop enough charge to cause this. Touching the metal on the rig will discharge things but it's hard to remember to do this. Am I missing a ground on this VFO knob or what? BTW...The FP is only a few months old, new version.
