Yes as I wrote earlier there are 3 places which are "in series" if you will,
that affect the audio level to the radio. In order: (a) Windows SPKR level.
(b) WSJT-X PWR slider, (c) K3S Line Gain.
I don't know anything about TX audio processing changes and I don't find it a
challenge or any difficulty to get the 5th bar to flicker. Again I will
comment that I find the default WSJT-X TUNE frequency of 1500 Hz does appear
to cause a beat with the ALC meter display refresh rate. It appears as a
fluctuation or pulsing of the value. By moving the TUNE frequency away from
1500 a 100 Hz or so I find the issue is resolved.

I had the line in on the radio at 35, but it varies as I tweaked the Windows
level.
I understand the TX audio processing has changed, and the operation
(sensitivity?) of the ALC reading makes it much harder to get the fifth
segment to flicker.
I went back to JTDX (and JTAlertX), which is much easier to get the correct
TX audio level.
