K3S Kit issue - Does not transmit in SSB

VE8EM
Good day,

I am adressing this issue to this forum as I am puzzled and don't know what to do.

Basically, I assembled my K3S kit about a month ago, no issues with the build and initial testing. I have done all of the required calibration and even the RF Gain calibration using the XG3 signal generator.

Everything worked out fine, I was able to receive signals and hooking up my paddle I was able to transmit in CW. Since I have the TX Monitor option, I was able to see the signal and power output on the P3 display.  I did put back the radio in his box and put it aside for about a month as I was busy with other family issues (i.e. a new baby).

I pulled back the radio last week as I wanted to play with the digital modes, after fiddling with the settings I was able to hook up the computer and the radio using the USB cable to use the internal sound card and control. I am able to receive signals on my computer, I can see the received signal on the computer display so I have no doubt that the sound card drivers are working. I configured the software to control the radio and when I start to transmit using the software, the radio turn into transmit mode and the TX red LED lights up. However, looking on the P3 Display using the TX Monitor, I see no signal being transmitted, if I increase the Monitor volume, I hear a hissing sound and there is no power output.

Since I initially thought this was caused by a setting, I hooked up the MH2 microphone and pressed the PTT, the TX LED lights up, but when I speak in the microphone, no signal appear on the TX Monitor, same hissing sound when I increase the Monitor Volume and no power output.

Does anyone have faced such an issue?   Any idea what is wrong?    

I have assembled many kits helping other people (K3, K3S, KX3, PX3) and never faced any issue but for my kit, I dont get it.

Thanks in advance!

Re: K3S Kit issue - Does not transmit in SSB

I would start by bringing your tests down to the basics and eliminating any possible computer software configuration cause.

I would first re-load the firmware and re-run calibration.

Assuming those all work correctly, the next issue is to properly configure the microphone settings.  There are several things that have to be correct, including where the microphone is connected (rear or front), the nature of the microphone, any bias and the proper microphone power setting (hi or low).  Read the manual and follow the instructions.

If you are still having problems, test with another microphone to make sure the problem is not with the mic.

If none of those work I would call the factory for further guidance.  They are excellent at diagnosis and are very helpful.

Etienne,

A frequent problem is that the Bias is not turned on when using the MH2
microphone.  It is an electret microphone and needs bias to produce audio.

As for your DATA mode operation, are you using DATA A mode?  You should be.
Do you have the mic select set to Line IN?  If not, that can be the
problem.  Do you have anything plugged into the K3S Line IN jack?  That
overrides the Line IN for the internal soundcard.
Do you get any indication on the ALC meter - you should set the audio so
you have 4 bars solid with the 5th bar flickering.  You may need to
adjust both the computer soundcard speaker or line Out sliders and the
K3S mic gain (actually Line IN).

73,
Don W3FPR

I would like to say thank you all for your answers.   The BIAS was the issue for the MH2 microphone, I am able to transmit SSB now but somehow I am still having issue with the computer connection...

I guess I will keep trying things out.

The menu option for MIC SEL is now showing front port and BIAS. It works!

The following option MIC+LIN I believe should be on to use both, am I correct?

I am still unable to use the internal sound card line in however...  I'll keep trying!

Thanks!

For DATA modes, use DATA A and set the data mode MIC SEL to LINE IN - if
you try to use SSB with MIC+LIN you will end up transmitting voice as
well as data through the live mic.

With the USB connection using the internal K3 soundcard, make certain
nothing is plugged into the 3.5mm LINE IN jack.

Adjust the soundcard slider and the MIC GAIN (now LINE IN gain) to
produce 4 bars solid on the ALC meter with the 5th bar flashing.
Adjust your desired power with the power knob.
Ignore the internet advice to adjust the power with the audio level, it
does not work well with Elecraft gear.

Finally,  I was about to give up but I managed to solve the issue.

After hours of configuration checking and trials, I installed some Windows update which prompted a restart.

After restarting the computer, and being quite stubborn, I decided to give it another try...  And it magically worked, no changes needed in the settings, just a computer restart and the driver settled I guess and it has worked since then...

Hopefully it will stay that way!

I have had the same thing happen to me numerous times, albeit not with
radio control software.   The machine will just lose its freaking mind and
when I shut it down, it'll begin installing downloaded (uninstalled)
updates.  I call it the computer's "throwing a temper tantrum."

Perhaps this thread — if it continues — should be renamed to what it is, a "PC Operating System fail” or something.  :-)

This is a really common problem with Win10. If it has downloaded a new
update in the background, but not installed it, many of the drivers quit
working. For me it is ALWAYS soundcard #1 that fails. Once a reboot is
performed, things start working normally.

Just a quick thought... make sure you are not in TX Test mode!
