[Elecraft] K3S, fldigi and Windows 10

[Don Wilhelm]

Bob,

Set the K3S to DATA mode with DATA A as the data sub-mode.  That sets 
compression and equalization to zero, otherwise it is the same as USB.
I am not sure why you have MIC + LINE selected, just set the input 
(while in DATA mode) to LINE IN.
I assume you are attempting to use the soundcard built into the K3S - if 
so, be certain there is nothing plugged into the LINE IN jack on the 
rear panel.

See page 33 of the manual.

To set the audio level, put the K3S into TX TEST and you can set the 
level without transmitting any RF.
Adjust the LINE IN level to produce 4 bars solid on the ALC meter with 
the 5th bar flickering - that is the "no ALC" point for the K3S (ALC 
begins at the 5th bar).
Failure to set the audio to that level will result in the K3S "power 
hunting" in an effort to maintain the power level you have requested 
with the power knob.

You can use both the computer audio playback slider and the K3S 'MIC 
GAIN' (it will set the line in level).

To change the soundcard settings in Windows 10, right click on the 
speaker icon in the right lower corner of the screen, then select 
"Playback Devices"
In the window that opens, right click on the device that represents the 
soundcard you wish to control and select Properties.
On the window that opens, click on the Levels tab and you can see the 
slider for either Speakers or Line Out - adjust the slider with your mouse.

I don't know of any documentation specific to the K3S.
For the VOX problem, check the setting you have for VOX delay.

73,
Don W3FPR
