[Elecraft] ALC on line in?

[Don Wilhelm]

Jamie (and all),

I post this information frequently.

Adjust the audio input level to produce 4 bars solid on the ALC meter 
with the 5th bar flashing.

That usually means setting the soundcard output slider on the computer 
to about 75% and then adjusting the K3(S) MIC GAIN (actually LINE IN 
gain) to produce that condition.
The onset of ALC is indicated by the 5th bar on the ALC meter.

Adjust the desired power output level with the POWER knob (not the audio 
level).

Elecraft transceivers control power differently than other amateur 
transceivers - set the K3 as indicated in the manual and ignore the 
internet advice (and some software instructions) which would have you 
set the power to full and adjust the power output with the audio level.
That does *not* work with Elecraft transceivers.  To do so will result 
in erratic power output.

73,
