[Elecraft] Curious Power Output on PSK

Correct.

I think this is a misunderstanding.  There must be at least 4 bars of ALC.

On the K3, the ALC indicator is based on audio input, *not* RF feedback.

If you can't get 4 bars of ALC, you need more audio from the computer, 
or more LINE IN gain.

If you have less drive, you will get Tx Power creep, because the system 
Tx gain is set based on the audio level being at least 4 bars of ALC.

Hope this is helpful to you.
