Just to be clear on the point. The correct audio level should produce 4
bars indicated on the ALC Scale. Actual ALC action does not start until
after the 5th bar.
Yes, after any power adjustment, the audio system does start at lower
gain, quickly ramping to the desired level. This is done to prevent any
potential power overshoot. After the initial transmission at the new
power setting, the remainder of transmissions are at the proper power
level setting.

I just set the audio to be sure I'm? hitting 4 bars of ALC,and the cycle
of adjust K-3 power to full expected drive to the KPA-1500 is now more
like CW, but the question remains -? after I adjust the power a tiny
fraction in either direction, why does the K-3's output power drop way
back and relatively slowly recover?
