Hey, Cliff. So, the gnd hole you spotted doesn't have anything in it. It must just be the way it looks in the photo. For getting audio in, I followed someone else's advice and reloaded the firmware. I then got transmit via putty and now I am getting audio in. I've gotta another piece to this puzzle, though. A friend of mine built a QDX a few weeks ago. His works, so he broight it over for me to try. Guess what? It doesn't work on my computer. I'm seeing the same fail with it as I do with mine. So, I'm thinking my problem isn't with the radio. It is something with my computer. I tried changing the USB cable out, but that didn't change anything.

Steve, Dimension 4 works with Windows 10.

Re: QMX - What are my options?
Consider yourself invited to do so.? Hans will do the build as previously agreed.? I will make one addition.? See September QST page 33. I have downloaded the software.? Your past kindnesses has not been forgotten.?

Glad to hear it, Karl! Good luck with the flea sized solder surgery! :D

Wayne,
L12 is for receive BPF so it shouldn't affect Tx. Of course make sure the blob isn't hitting something else that it shouldn't be. In the first photo it looks like solder in the "GND" pcb hole between the trifilar and L12 toroids. It's probably just and illusion, but that hole shouldn't have anything in it.
Just curious, what did you do to get Rx working now??

Does anyone have an idea what role L12 might have as it relates to my problem. I had a bit of trouble getting that one wound, but I did finally get it. I do, however, have a small tower of solder that came from the bottom of my board where I soldered it. I believe it's the first tap.

Thanks for that info! I downloaded and installed the latest and found the QRP Labs radio config. No, it didn't fix my problem, but it was certainly worth a try.

I have several of the ViFly for my FPV drone hobby builds. Hadn’t considered using one in the application but I bet it would work great. It trips very quickly, but I haven’t measured the exact time.?

Ok. What happens after the CAT test and you push PTT, does it turn red? Another click on PTT turns if off.
Tested your radio config and it works FB here. FYI, if you have the latest Wsjtx there is a rig option for the QDX that will let you use Split operation by selecting Rig rather than None. It's called QRPLabs QCX/QDX. You might try that. I doubt it'll fix the problem, but it's setup especially for the QRPLabs rigs so you might want to use it.

Certainly. Here are my setup pages for Radio and Audio. When I test the CAT, the button does turn green. I am able to change frequencies through WSJT-X.

Do a factory reset and try again

I meant only to rig up temporary linear supplies on my bench
hello Rick, Hello Hans, this is exactly what I was aiming for myself: a temporary replacement of the smps boards until all other smoke tests have been succesfully passed. Hans: really no offence intended! I am of an older school and do not trust these new-age gadgets piloted by software, not because of paranoia, but because of the fact that they do not belong to my trusted analog world. I find the ideas standing behind the SMPS concept of the QMX most refreshing and innovative: this is the main reason I am glad of having purchased a QMX, without having been in need of yet another qrp toy. But now.. I am sort of discouraged by my own courage and would like to go one step behind into those quiet linear waters I am used to. Not for good, but at least for the first current intake of the fine rig. Afterwards, having thanks to Chris a test checklist for the SMPS boards outside the rig, without danger of damaging the main professor, I would maybe gain some courage and "replace the linear replacement" with it's new age microprofessor controlled switching PS. This is what I meant. You might help by telling me if this is doable or if I am to expect some latch-up phenomena during power-up due to the fact that the 5V rail would come alive before the 3,3V would do. But latch-ups are not harmfull, so if you do not have an answer to this question, just forget it: I will find it out by myself. Yours friendly, Razvan dl2arl?

Hi, Chris. Thank you so much for your reply. Here is my PC audio setups for the QDX.

Certainly. Here are my setup pages for Radio and Audio. When I test the CAT, the button does turn green. I am able to change frequencies through WSJT-X.

Check that the QDX audio output in the
PC is on.? I had this with my QMX and it turned out that the QMX
sound output wasn't turned on.
Settings - sound look for the QDX and
check the volume is 100% and not turned off.

OK all. A big plus, but my troubleshooting isn't totally complete,
yet. I now can receive and decode! See below for a screen shot. As
far as transmit; though, I'm still not there. I can now transmit
via the testing menu via putty. I am putting out about 4 watts RF
on 20M, but I still cannot get any transmit from WSJT-X or JS8
Call. I have everything in my windows (win11) configurations set
to 100%, but still nada. What else should I be looking into?

Wayne,
What did the CAT Test and PTT Test show in the Wsjtx Settings/Radio page? Maybe post a screen shot of your setup.

Rick,
Second arrived! Been gone all day and just got back. Thanks for the time, effort and the stuff! One going in as soon as I recover from my day trip! Will report soon!

Barb, Documentation for Dimension 4 does not indicate whether it is compatible with Windows versions beyond Windows 7 and 8. Do you know if is compatible with Windows 10 and Windows 11?
