Running "no bars" of ALC in PSK/AFSK causes the microphone gain to be increased to compensate for the insufficient drive. This will result in added distortion (noise and IMD)."

So, no bars equals more noise and IMD or even one bar causes more IMD? These two statements seem to contradict each other. I'm thinking that the ALC will only limit mic gain, it won't bring it up if it's low, other wise you wouldn't have any dynamic range on your voice, the ALC would tend to make everything the same level. I'll just keep doing the way I've been doing it. I get good reports and the power output that I expect.
