Most of my GH controls (7 of 8) have remote pulse width modulator
amplifiers to drive KX0G rings. A problem with them is extreme noise
from the PWM amps, which I can only tame a bit. What the noise makes
obvious is when a GH causes rotation *on its own* and that is the
problem I'd like to understand/fix. They exhibit spurious, random
movement, with no USB connection or change in the direction setting pot.
There is no solution from GH other than some production had "noisy
pots". I've observed the problem on most of my controllers, so wonder
if others have had this problem and know of a fix.
