This seems to come up every few months. ALC is not the cause of the problem, it is a symptom. The cause is overdrive of the mic audio chain and/or balanced modulator. Poorly designed ALC can cause wide signals on voice but not with continuous carrier modes like FT, but this is not harmonic distortion but rather undesirable amplitude modulation. Harmonic distortion that shows up in the waterfall is generated in the audio chain, generally _before_ the point of ALC control.
