[Elecraft] FT8 TX levels = no power

Tue Jul 16 19:23:54 EDT 2019

Peter:

In that configuration there are 3 specific places where adjustments are 
needed for transmit levels.   Left click on the SPKR icon in the lower 
right side of the computer display.  Set that slider to a value between 
30 and 50.    That controls the transmit audio via the software.  And in 
WSJT-X set the PWR slider {which does not actually control power} to a 
value of about 50% or mid scale.  Then on the K3S you MUST be in DATA A 
mode.  The press MENU and scroll to MIC SEL.  It should be set to Line 
In using the A VFO knob.   Then exit that menu.    Use the Speed/MIC 
knob to control LINE gain to attain 4 solid bars shown on the ALC scale 
with WSJT-X in TUNE mode.  The 5th bar should be flickering. With WSJT-X 
in TUNE mode, move the TX audio frequency away from 1500 Hz as there is 
a beat between the tone and refresh rate of the display and will cause 
what appears to be pulsing of the audio.   Adjust  the actual 
transmitted power using the normal radio PWR control.  NEVER change the 
audio level to adjust power output.

For setting receive level you should RIGHT click on the SPKR icon which 
should  bring up a menu.  Then LEFT click on OPEN SOUND SETTINGS.   This 
will bring up the WINDOWS Settings page.  At the top in the box you 
should have SPEAKERS USB Audio CODEC selected. Then down below is the 
bar showing level and it should be about 30 to 40.    Then a bit down 
the page is INPUT.  In the box it should be showing Microphone (USB 
Audio CODEC).    Click on Device Properties and you can adjust that 
slider to attain a value of about 30 or so on the WSJT-X  level 
indication on the left side of the WSJT-X pane.

Now all of this is not nearly a complex as it sounds.  One just needs to 
know where things are located and what to adjust.   As a general rule 
one never wants a control at or near maximum and likewise, never near 
minimum.    The three places must be used "in harmony" in order to 
attain excellent results.

I've been running my K3S for several years with WSJT-X and other audio 
modes very successfully.  I've just updated to the 64 bit version for 
Windows 10 and it is GREAT!

If you need screen shots, I'll be glad to provide same.

I don’t know if there are any more level controls involved, and to be honest, I never like to run anything wide-open.
