[Elecraft] Weird K-3 Power Behavior

[Bob McGraw]

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.
