[Elecraft] K3s Transmit question

Gary,

Are you working in DATA A mode, and driving the audio to 4 bars solid 
with the 5th bar flickering on the ALC meter?

That is the No ALC point for the K3/K3S/KX2/KX3.  The lower bars are 
there to give you a guide to adjust the audio.

So the common internet advice not to drive into ALC is being observed - 
it is just that to point where that occurs is at a full 5th bar on the 
ALC meter.

Moving the power knob "reactivates" the power control circuits, but if 
you do not have enough audio, the power will not be steady - the radio 
will "power hunt"

73,
