Within FLDIGI there is a transmit audio level control in the lower right
corner. Just below the LK tab. I use a value of -15. The arrows
left and right of the box will increase or decrease the level going to
the radio. My Line Gain which is adjusted by using the MIC knob is
at 30.
There are 3 places where the transmit audio level should be adjusted.
(a) The computer SPKR level. {mine is 30%}
(b) The application transmit audio level {mine is -15}
(c) The radio Line Gain level {mine is 30}
Ideally, they should never be at a maximum or near minimum value but
more near "mid range". I call that between 30 and 50 what ever units
that may be. This will prevent overdrive and distortion of a stage
or circuit. And these should supply adequate level to the radio to
produce 4 solid bars showing on the ALC scale. With Elecraft radios,
always set the transmit power output with the PWR control on the radio
and NEVER with the audio level. Also be advised that often when one
runs another application previously on the computer, the SPKR level many
change due to the needs or a previously used value. Just the way some
things work. Always check the values to prevent frustration, bad
signals and "nothing works" conditions.

I hope someone has solved this, too, as I am having the identical problem with my
KX3. Other digital modes like FT8 work FB. I would like to not have to use VOX to
key the rig. I suspect that I just haven't found the right combination of trial
& error.

I am running into the exact same thing. fldigi gets audio and freq from rig
no problem. USB codec selected for fldigi output but rig just shows TX light
but no power out or ALC indication on rig. Nothing plugged into line in
jack. Rig set to TX DATA. MIC SEL = Line in on rig. Same symptoms with
FreeDV and WSJTx...
USB audio and rig control fine and PPT works but no rig sound card going
out.
anyone else find this and solved it?
Thanks,
