Re: [Elecraft] K3S USB audio output needs to be adjustable in Menu

[Bob McGraw K4TAX]

I find Don's info to be exactly correct as it applies to the USB 
connection between the radio and computer.As to the Line IN and Line 
OUT on the back of the radioI've never used it.


With Windows 10, if you wish the Sound Card to show the levels in dB, 
just right click on the level slider in the Recording devices for 
example.  This will give one the option of displaying the level as  
"decibels" or "percentage".   For WSJT-X I find 0 dB about optimum, for 
HRD/DM780 I use +10 dB and for FLDIGI and MMTTY about +15 dB seems 
best.For the Speaker level, adjust about mid scale with a full scale 
value of 50 .   In the Playback devices window the level is about - 10 dB.


The default value for LINE OUT in my K3S is 010.   I've found no need to 
change this as the other controls in the computer and application 
software are most adequate.  All this applies when using DATA A mode in 
the K3S.  If you aren't using DATA A mode, then be sure any EQ or CMP 
values are set to zero.

Jim,

What are the settings for the K3S CODEC in the computer?
Look at your soundcard settings and set them to something lower. There 
is normally no need for an additional control in the K3S other than 
the normal LINE IN gain settings.  The settings for the K3/K3S 
computer LINE OUT (or SPKR) should be about 50%. but lower is K too.  
The K3/K3S should be set to some mid-range value.  If very low or very 
high, adjust the computer soundcard settings until it adjusts in the 
K3/K3S midrange.


Same goes for LINE OUT - the soundcard LINE IN should be set to about 
50% in the computer, set K3/K3S LINE OUT to some value near 8 or 10.


For soundcard data modes, you need to adjust the audio drive level for 
4 bars solid on the ALC mater with the 5th bar flashing - that is the 
NO ALC point for the K3/K3S.  Adjust the power level with the POWER 
knob. To do it like the JT instructions tell you will lead to power 
"hunting" which will include power overshoot.


Ignore the JT instructions and the common internet advice which is to 
set the power to full and adjust the power with the audio level.  That 
is for other transceivers.  The Elecraft transceivers control power 
differently than all other amateur transceivers that I know of.  Some 
commercial gear does work like the K3/K3S with a closed loop power 
control system.

Wrong!  The stereo input of "USB Audio CODEC" is fed by the "Line

level into USB Audio CODEC.

Re: [Elecraft] K3S USB audio output needs to be adjustable in Menu

[Bob McGraw K4TAX]

See the CONFIG Menu, LIN OUT to adjust level.  Normal is 010.

Hello Elecraft,
  
When feeding the audio from the K3S USB port to the CPU, the K3S audio

level is extremely high and way too hot for good performance  on many digital
modes.
  
Example, even with my CPU's sound card set at the lowest possible level of

"01" my K3S is hitting the JT-65 software with a super strong signal that
is  much higher than the software wants to see and performance is degraded.
The same is true when operating RTTY using MMTTY or 2Tone software.
  
The USB audio output on the K3S needs to be adjustable in the K3S Menu as

it was on the K3 Serial port.
  
I wrote to you a few months ago about this without a positive  reply.

Please address this serious issue.
  
Thank you-

my RF  gain control at its normal position (around 3 o'clock) and use the
slider  at the lower left in the WSJT-X window to compensate for  gain
variations.

  Bret,

You may have better luck with running the RF Gain full  and adjusting
with the AF gain.  That way the RX AGC will smooth  out variations in the
signal level.
