yep, that's what I'm getting. attached is audio scan, looks bad. Paul DJ0CU

Ok, Probed the clock outputs, nothing, pin 13, sc has nearly 5v on it while pin 14 is very low. Pin 18, pll has 3.3v. Possibly Q7 died? Andy -- The universe is made up of Protons, Neutrons, Electrons

Thanks for that catch. I changed that default, but I'm still not getting any audio to the QDX. Wayne

Wayne, On the second screen print, I noted that the QDX is the default output device.? It could be that the system is taking over the QDX audio and not allowing the WSJT-X to access it.? Since I do

All, I would recommend patience.? The QMX has a very capable processor to process the audio.? Hans will add the AGC into the software at some point.? This should be much better than the simple

Here is my setup with the QDX:

Nope. -mike/w1mt

The AGC kits don't work on the QMX though, do they?

?? true

Wayne, Based on the TX working with PuTTY, there is most likely a configuration issue with your computer.? I suspect the volume setting for the QDX audio output (Speaker) is most likely the issue.?

Okay. Now you know one thing it AIN'T!

One obscure issue with time sync: I have a cellular internet modem (T-Mobile) and it will not allow most of these time syncs, such as Dimension4, or many others, to work. It will also not allow ftp

I read this with interest a few weeks ago and would be interested in Hans' thoughts on a commutating diode across L14 and wondering if perhaps there might be a future revision to the QDX?

Check the voltage at C406. One is ground the other should be about 2.5v. -mike/w1mt

I just tried JS8 Call. I'm still not getting any power out and seeing two flashes on the LED. I also got this error, which I have also seen in WSJT-X:

Hi Karl, no, on my board c509 is fitted, sitting snuggly next to R510. Paul DJOCU

Hey, Alan. Thanks for the info--you guided me over to it perfectly. It looks like the microphone permissions are set correctly for WSJT-X.

Hey, Evan. So, two answers: 1: The wall wart says 2A. To be honest, I just assumed 2Ah, I think I just learned something. Thank you! 2: OMG...you got me a step closer!! I get about 5 watts

WB2CBA's post did not include "CAT" - just PTT through VOX. If you are just interested in PTT, I'd suggest USB sound cards with GPIO. A much simpler (resistor and transistor) PTT solution which is
