K3S USB audio output needs to be adjustable in Menu

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-

Richard Van Zandt- K9OM

variations.

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

USB audio with the default settings has been fine for me from the first
day. Check your settings?

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

Richard - I second your report, there is no fine adjustment for the USB
audio on the K3s either in received audio or transmitted audio. When the
band is noisy, I have to reduce LIN OUT to 01 or alternatively reduce
the overall system gain with the RF gain (which in the case of the K3
and K3s is IF gain).

When operating meteor scatter on 2M with an Elecraft K144XV transverter
I had to reduce the audio drive from the JT65 software to 50% to prevent
RF power out overshoot and hunting, typical in over-driven closed loop
systems. This allowed me to advance LIN IN and the end result was the
power detection system of the K3s settled down.

There are work-arounds.

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

Can't help but wonder, is anyone adjusting the recording and playback in
Windows?

Mine works fine by adjusting those. I don't do any vhf though.

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

Gotta remember that there's no audio here, just numbers that represent
audio. Somewhere in the PC there is a setting that instructs a program to
set a reference level for the digital signal. It's not at all like running
coax from line out jacks. The digital doesn't pick up hum or flat-top. Just
numbers being thrown around. Audio from the K3S via USB is never actual
audio in the K3S. After the low IF hits the A/D converter, it's number soup
everywhere between the A/D and the far end of the USB cable.

Wrong! The stereo input of "USB Audio CODEC" is fed by the "Line
Out" analog audio. Adjusting MENU:LIN OUT will adjust the audio
level into USB Audio CODEC.

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

In reply to this post by James Rogers

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.

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

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 radio........I'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.
