    Sorry I did not see this sooner. I was not a member of the group until now.
    The FTdx10 has a number of idiosyncrasies associated with SSB. The major problem is adjusting the mic gain, processing gain, and the AMC (automatic microphone control). These interact and just increasing the mic gain will not increase power depending on the other settings. If you use the processor (which I do), your power meter will more closely match the peak power, as expected. As I recall, the ALC meter reading is used to adjust the processor level. It is not helpful for mic gain because of the AMC. There are some detailed discussions on how to adjust the three controls. The AMC is especially vexing, because it seems backwards.
    When properly adjusted, the transmitted audio is clean sounding and has good punch, and the power peaks are not stuck at 50W. A spectrum analyzer can be helpful. The manual is not.

Bias is a tendency to favor or lean towards one perspective, person, or group, often at the expense of another. Bias can be conscious or unconscious (implicit) and can influence judgment, decision-making, and behavior. Unlike prejudice, which is explicitly about preconceived notions, biases can be more subtle and can even occur without the individual being fully aware of them. Bias is broader and can be positive or negative, affecting various aspects of life like decision-making in work, preferences in social settings, etc. Bias is basically a difference of opinion and that must be respected. Prejudice, however, refers to negative, preconceived opinions or attitudes held by an individual or group towards another group or individual, often without factual basis or experience. Prejudices are usually harmful, leading to unfair treatment or discrimination. They are often based on stereotypes and can be about race, gender, religion, nationality, or any other distinguishing characteristic. Prejudice is more about feelings and attitudes. Ham Community does not tolerate prejudice. We are all different, that's fine. Remember, duty and honor are built on respect. Use this reporting category sparingly and only if you are quite certain that the member is being openly and hurtfully prejudiced.
