Would that small change cause the dial to lock while transmitting? Could explain what EA3IAV is seeing...Perhaps having the lockout sensor trigger on something greater than "any change"?
The lockout is only triggered when the analog voltage changes more than 5 steps (there are totally 10,000 steps from min to max pot position). 5 steps is normally sufficient to prevent the lockout being triggered by noise that may be picked up by the wiring or from the pot itself. We could increase this value to make it less susceptical to noise, but in EA3IAV's specific case I doubt it will help. The problems as he describes them indicate that there's more going on than just a bit of noise on the potentiometer, perhaps grounding issues, poor or incorrect wiring, faulty components, etc?
