"It will remain as clean as the audio, up to the point the ALC begins to kick in; then it goes bad like any other radio. That’s the fault of ALC, not the radio."
What goes bad? Nothing goes bad for a Kenwood TS-590S when drive level moves into the ALC closed loop control range. Remember that WSJ-X mode are very close to constant amplitude so ALC dynamics should not be a factor. I have no idea how ALC works in a K3 but in a Kenwood TS-590S it controls the gain of a transmit IF stage.
There are lots of operators in the Phoenix metro area and many of them have good equipment and are technically competent. I'm very willing to run an on-air FT8 test in which I drive my TS-590S through the full normal ALC range. I'll let my peers judge my signal and if they find any problem with it I'll change the way I operate.
