[Elecraft] K3S and WSJT-X

Mon Jan 25 22:07:50 EST 2016

I now have Mic Gain at LINE 7 per p. 88 of KE7X's book and the WSJT "Pwr
slider" at about -8.8dB to make the 5th ALC bar flicker.

Let me clarify a point.  Use the PWR slider on WSJT-X to adjust the number
of bars on the ALC indication on the radio.  Do this in 
combination with the {MIC}  Line Gain value on the radio.   You should 
have 4 on solid, 5th flickering.  Actual transmit power is controlled by the
PWR value as set on the radio.

movement results in a big swing in actual power.

affected by the SPEAKER level in the Windows Sound controller panel.  Also
under "Enhancements" make sure "Disable All Enhancement"  box is checked.
