Re: [Elecraft] WSJT-X and K3S Tx

[MaverickNH]

Hi! I got the below advice which worked for me: For WSJT-X and the K3S use: 
Mode = DATA Data sub-mode = DATA A MENU:MIC SEL = Line IN Make sure nothing is 
plugged into the "LINE IN" jack. Set the PWR slider in WSJT-X to the top, click 
Tune and adjust the K3 MIC GAIN for *four bars* of ALC. Adjust the K3 PWR 
control for the desired power output. Best regards, Bret C. Bret Jessee --

I am having the same problem, with not being able to send audio to my 
K3S from WSJT-X. The transmitter is being keyed, but nothing is showing up on 
the ALC. I normally use WSJT-X with HRD, but have tried to bypass HRD to see if 
the will work by going direct, which did not work either. It has been working 
fine until this morning when it quit working. I am able to send the audio to 
the K3S using DM780, running PSK31. 
I am running Windows 10 on a HP I5, 64 bit. The computer has two sound cards, 
one for digital and the other for YouTube, music and such. For digital I am 
setup in both HRD and WSJT-X, with the sound card settings Speaker USB 
Audio CODEC. A few days ago I was able to have my default sound card set 
to Speaker Envy24 Family Controller, but something happen and now 
the only way I was able to get the sound to the K3S was to change the default 
sound card to Speaker USB Audio CODEC.
However, I was able to work PSK on the HRD DM780 with the default sound card 
set to Speaker Envy24 Family Controller, but not with WSJT-X.
I did update my Firmware on my K3S this morning to 5.56, if I remember 
correctly the WSJT-X was working correctly after words.
Uninstalled the WSJT-X and reinstalled with no change in the problem. I have 
been operating WSJT-X now for about 2+ years, so I am not a newbie. However, I 
sure am pulling my hair now

Re: [Elecraft] WSJT-X and K3S Tx

[MaverickNH]

OK - thanks Rich, Don & Kevin.

1) COM3 was my XG3 RF Signal Source USB Serial Port - silly me...
2) PC Sound Card is now Default - I had to plug something into the Blue Line
In and Green Line Out jacks for them to be Ready so I could select them as
default
3) Nothing in K3S Line In jack; U7 card connected to the LP-PAN2
4) WSJT-X Line In/Out set to the K3S USB Audio CODEC
5) DATA A selected as mode
6) Did a manual TUNE to each WSPR frequency, so they are now stored in
memory
7) WSJT-X/WSPR-2 Mode waterfall dark background with clear and sharp signals

Do I want my XFIL wide open to FL1 4.00?

Like Kevin says, I'll quit messing with it - it works.

Thanks again!

Bret/N4SRN

Re: [Elecraft] WSJT-X and K3S Tx

[Kevin]

Both Rich and Don have given good advice.

Make sure the U7 or onboard NVIDIA sound device is set as default so you 
don't broadcast windows sounds. Make sure the USB Audio Codec Speaker 
and Mic are enabled but not set as default. In the WSJT software select 
the USB Audio Codec as the sound device for line in (Microphone) and 
line out (Speaker) respectively. Set mic gain levels on the K3s so you 
get four solid bars and an occasional flicker of the fifth on the ALC 
when transmitting. Set the K3s line in level to achieve a medium blue 
background on the waterfall. Use the K3s power control to adjust output 
power.


I'm not quite sure what the tune function in the software is about. What 
does the K3s SWR meter say? Is the tune button in the software supposed 
to kick the K3s into transmit and not doing it? The tune button on the 
K3s only controls the internal tuner or the outboard KAT500 and neither 
will "tune" unless a certain SWR threshold is met.


If you're transmitting signals and receiving them and neither is over 
driven quit messing with it.

That is where Windows sounds are sent, YouTube audio and other media player

3. In WSJT-X, in the File > Settings menu under the Audio tab, set the
Input and Output sound cards to the ones you are using for sound card modes
- most likely the USB Audio CODEC in the K3S, unless you have chosen to
bypass it and use an external sound card plugged into the Line In jack on
the K3S, which disables the K3S's internal sound card. If you are using the
U7 with LP-PAN for panadapter software, it is *not* the sound card you are
using for sound card modes, and it should *not* be connected to the K3S's
Line In jack - it should be connected directly to the LP-PAN. In that case,
WSJT-X should be set to use the USB AUDIO CODEC and there should be nothing

4. The ATU on the K3S is not triggered by a transmitted signal, whether
from WSJT-X or elsewhere. It is not auto-tune in that sense; it is
auto-tuning based on frequency memories, which is what the KAT500 calls MAN
mode. It will automatically switch to the last setting used on that band
segment with that antenna output (ANT1 or ANT2). Once you have tuned the
ATU once with your antenna for a particular frequency, that should be good
enough from then on. If your antenna's SWR changes dramatically because of
weather conditions, e.g. ice on the antenna, you tune the K3S's ATU using
the ATU TUNE button on the K3S. Therefore an extra 2-second tune signal
between band hops does not do anything useful, other than give you a
2-second advance notice of the SWR.

5. When the K3S's meter is in ALC mode, it does not show the transmitted
power. You have to put it into PWR mode with the METER button. The TUNE
button switches from ALC to PWR mode automatically, but transmitting
normally does not do this.

Re: [Elecraft] WSJT-X and K3S Tx

[Don Wilhelm]

An additional "By The Way" comment - Windows normally sets the last 
installed soundcard as the default.  Your U7 soundcard was likely set to 
be default when it was installed.
You can set the default back to the internal soundcard (the NVIDIA) if 
you are trying to use the U7 with LP-Pan2.

Re: [Elecraft] WSJT-X and K3S Tx

[Don Wilhelm]

Bret,

Do not set the K3S CODEC to be the default soundcard - the default 
soundcard will be the one that plays sounds from the OS (Windows 
Sounds), and those sounds should not be transmitted on the air.


The "Recording" setting level is audio from the K3S to the computer (not 
K3S recording).  Use that level as well as the K3S LINE OUT level to 
adjust the waterfall display brightness.


Look at those soundcard settings (Input and Output) from the perspective 
of the computer and not the K3S.
Even though the soundcard is in the K3S, it is still the "property" of 
the computer - the same as any other external soundcard.

Unlike when I was using a FT-897D, the short 2-3sec TUNE tone between band

ATU triggered when in the 2min WSPR-2 mode TX cycle. With WSJT-X TX, the K3S
red TX LED lighs, and now I see ALC bars, but no power indication as when
pressing the K3S TUNE button. But I my WSPR-2 mode TX is being heard and
logged in WSPRnet (N4SRN) so there is RF power out.

Re: [Elecraft] WSJT-X and K3S Tx

[MaverickNH]

Hi Bill - We might be talking two different things. WSPR & WSJT-X have an
option under band hopping to send a 2-3 second tune signal before each RX so
that an ATU can recall the tune parameters for that frequency from memory.
That's not happening for me.

It isn't supposed activate the auto-tune. It provides a TX signal to allow you

Re: [Elecraft] WSJT-X and K3S Tx

[Don Wilhelm]

Bret,

Reduce the soundcard level setting in your computer so you have a 
greater range of control with the MIC Gain setting.

Adjust so you get 4 bars solid with the 5th bar flashing.
7 bars is too much - you are driving into the ALC region.
The No ALC point for the K3 and K3S is at the 5th bar.

Re: [Elecraft] WSJT-X and K3S Tx

[Kevin]

Sounds to me llike you have the wrong sound card line out setup.

When you plug the USB cable in the computer there should be three 
entries in device manager in control panel once the drivers are loaded. 
One under the "ports" heading which should say "USB serial port" write 
down the Com port number you're going to need it. The other two will be 
under the sound heading in device manager. One Microphone labeled USB 
Audio Codec, the other a Speaker with the same label. Make sure the 
Speaker with the USB Audio Codec label is set active instead of the 
onboard sound card of the computer.


That speaker setting is your line out level from the computer to the 
K3s. The microphone USB Codec is the line in level for the K3s to the 
computer. Both need to be enabled on the PC and levels set properly.


If you have two USB sound cards you need to figure out which one is the 
K3 and which is the computer.


This applies to a Windows 7 and up computer.

The internal soundcard in the K3S should show up as a separate USB 
soundcard (Codec) in your computer.

Just wondering if this could be the issue?  I see you can chose K3/KX3 
under CAT, but no listing of K3s.

I confess I do not use WSPR-X very much but I checked my version and 
the K3s is not shown in setup.  Plenty ways to chose a com port and a 
soundcard, but one does not use a computer soundcard with the K3s 
connected via USB port.


Just wondering if this could be the issue?  I see you can chose 
K3/KX3 under CAT, but no listing of K3s.


With my K3 I merely set up com port (for PTT) and select the 
soundcard from the drop-down list at the bottom of the setup window; 
I don't enable CAT in WSPR-X  v0.8 r3058; possibly it is in later versions.

Bret,

One more thing - if you are using the K3S internal soundcard, make 
certain you do not have anything plugged into the LINE IN jack.
A plug in LINE IN overrides and disconnects input from the internal 
sound card.

Bret,

How do you have the LINE IN level set?  Try increasing it to see if you 
can get a waterfall display.

I switched to DATA Mode and Data A but WSPR-2 shows no Rx, there is no

Where do you have your soundcard level set? Set it at the 75% point or 
a bit higher. 

One "eccentricity" of the KX3 is that *if* the audio input is too high 
the KX3 will protect the audio input by shutting it down. Start with the 
MIC GAIN at a low level and bring it up slowly until you find the point 
where you have 4 bars solid on the ALC meter. If the mic gain setting 
is at a rediculously low level, you can add some attenuation in the 
audio cable - 100k in series and 10k across the line at the K3 end will 
give you about a 10x reduction in input to the KX3. 

Instead of using USB mode, use DATA A - it is almost the same thing, but 
compression is automatically turned off and the equalization is 
automatically set to flat. That leaves your SSB settings intact when 
you go back to voice.
