WSJT-X and K3S Tx
Locked

Working to get WSJT 1.7 alpha running with my K3S. I saw some other posts but found no solution. I can Rx just fine, just cannot Tx. Pressing TUNE on the K3S gives Red TX LED and obvious Tx evidence from display with ATU TUNE enabled.
Settings:Radio are Rig Elecraft K3/KX3, COM 7 (correct for my rig), Baud Rtae 38400, Data Bits 8, Stop Bit 2, Handshake None, DTR/RTS blank, PTT Method CAT, Mode USB, Split Operation Fake-it, Poll Interval 1s. Band Hopping enabled, with CAT working fine it seems. The Settings: Radio tab give a Green CAT and Red PTT when tested. But no sign of power out, even though TX LED lights on K3S. MIC is adjusted to 23 such that USB voice gives ALC to 4 with occasional spikes to 5. Increasing MIC while WSJT-X is TX'ing doesn't budge ALC. I must be overlooking some K3S setting (as usual). Appreciate some help! Thanks, 73s, Bret/N2SRN |

Procedure should be same.

I've used that in my set-up of app and rig, but no go. I might be missing something simple as a K3S newbie. With USB as mode, and VOX enabled, perhaps Tx is not enabled? When the app goes to Tx, or it do a Tune from the app, the K3S Red TX LED comes on, but ALC doesn't budge.

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. 73, Don W3FPR On 9/14/2016 9:05 AM, MaverickNH wrote: > I've used that in my set-up of app and rig, but no go.

Hi Don - I'm running on a K3S rather than a KX3 so working with the internal sound card..
I switched to DATA Mode and Data A but WSPR-2 shows no Rx, there is no signal apparent on the waterfall.

Bret,
How do you have the LINE IN level set? Try increasing it to see if you can get a waterfall display. 73, Don W3FPR On 9/14/2016 11:35 AM, Charles wrote: > Hi Don - I'm running on a K3S rather than a KX3 so working with the > internal sound card.. > > I switched to DATA Mode and Data A but WSPR-2 shows no Rx, there is no > signal apparent on the waterfall. > > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

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. 73, Don W3FPR ------------------------------------------------------------------- Bret, How do you have the LINE IN level set?

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. 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: [hidden email] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

Ed,
The internal soundcard in the K3S should show up as a separate USB soundcard (Codec) in your computer. 73, Don W3FPR On 9/14/2016 8:43 PM, Edward R Cole wrote: > I confess I do not use WSPR-X very much but I checked my version and > the K3s is not shown in setup.

Thanks for the replies all. Just back from travel - sorry for the silence.
OK - on DATA A now and getting Rx on the waterfall. So Rx but no Tx. No Don, nothing plugged to rear LINE IN jack, and MIC SEL to LInE In. The MIC level was indeed low, and bumping it to level 6 yields an ALC meter raeding of 7 bars when in select TUNE from WSJT-X app. I hear the tone through my headphones, which might not be right - or is that just monitor? Either way, success! I'm being heard. Many thanks! Bret/N4SRN |

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. On 9/17/2016 3:37 PM, MaverickNH wrote: > Thanks for the replies all.

Hey Kevin - sorry, edited my post to note I'm being heard while you were replying. Sorry about that - your comment were otherwise on the mark.
One remaining niggle - the WSJT-X "Tune" option in Band Hopping doesn't seem to trigger my K3S ATU TUNE. Not sure why... Bret/N4SRN |

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. 73, Don W3FPR On 9/17/2016 4:37 PM, MaverickNH wrote: > Thanks for the replies all.

It isn't supposed activate the auto-tune. It provides a TX signal to allow you to adjust your ALC and maybe check SWR. If you want to use ATU, just tap Tune button on K3.

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.

Kevin,
I do find the Serial Port for the K3S as COM7, and also have a ASUS Xonar U7 external card on COM3, running through a LP-PAN2 I'm also working to configure. That's a somewhat separate topic. I have several sound cards, it seems. My Windows 10 PC Device Manager lists: High Definition Audio Device NVIDA High Definition Audio Device (from a G-Force audio/video card, 4 separate lines in Device Manager) NVIDA Virtual Audio Device (that NVIDA card again) USB Audio CODEC (likely the K3S) Xonar U7 (an external card) At present, my default devices are: Playback - Headphones Xonar U7 Recording - Line Xonar U7 I see the USB Audio CODEC as, not default, but "Ready" under: Playback - Speakers 3 - USB Audio CODEC Recording - Microphone 3 - USB Audio CODEC When WSJT-X/WSPR-2 Mode is TXing (both the full 2min WSPR-2 mode TX and the short 2-3sec tune-up TX tone), I see some bars turn green to the right of the Playback - Speakers 3 - USB Audio CODEC entry, suggesting the the K3S card is enabled, despite the Xonar U7 setting as default. As Don suggests, I went to the K3S Playback - Speakers 3 - USB Audio CODEC and saw the Level was 100%, so I cut that back to 20%, which gives ALC 4 bars with flickering 5 bars. Advanced Tab shows format to be 16 bit, 44100 Hz (CD Quality). Unlike the Xonar U7 card, there is no 192 KHz option. For the K3S Recording - Microphone 3 - USB Audio CODEC I have that set at 50%. That slider and the WSJT-X slider for digital gain are interactive. I can set the max on the PC and back it down on the app, or lower on the PC and bump it up on the app. Unlike when I was using a FT-897D, the short 2-3sec TUNE tone between band hops doesn't trigger the ATU when set to AUTO (I'm running 5.0W). Nor is the 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. |

1. The U7 is not on COM3. Sound cards do not use serial ports. Perhaps COM3
is a virtual COM port created by LP-Bridge, or perhaps COM3 is the K3S's USB serial port, and COM7 is a virtual port created by LP-Bridge that you connect other software to. You need to get this straight for other reasons, but it has nothing to do with the audio issues with WSJT-X 2. Your default sound devices should be set to the motherboard sound card. That is where Windows sounds are sent, YouTube audio and other media player stuff goes, etc., and you don't want any of that stuff going to the sound card(s) you use for radio, much less to the sound card you use with LP-PAN. 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 connected to the K3S's Line In jack. 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. 73, Rich VE3KI ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

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. 73, Don W3FPR On 9/18/2016 9:40 AM, MaverickNH wrote: > I see the USB Audio CODEC as, not default, but "Ready" under: > Playback - Speakers 3 - USB Audio CODEC > Recording - Microphone 3 - USB Audio CODEC > > When WSJT-X/WSPR-2 Mode is TXing (both the full 2min WSPR-2 mode TX and the > short 2-3sec tune-up TX tone), I see some bars turn green to the right of > the Playback - Speakers 3 - USB Audio CODEC entry, suggesting the the K3S > card is enabled, despite the Xonar U7 setting as default. > > As Don suggests, I went to the K3S Playback - Speakers 3 - USB Audio CODEC > and saw the Level was 100%, so I cut that back to 20%, which gives ALC 4 > bars with flickering 5 bars.
