Hi Ramon,
many thanks for the detailed explanation. HOWEVER¡­?facilitates multiple QDX on one PC¡­??is not quite accurate. I see a dangerous precedent being set here with a split from ANY PC (and so ANY operating system) is now ¡®some features work on Linux based PCs and some features don¡¯t work on Windows based PCs.

This is the first time I have seen this operating system split in QRPLabs products.?

I have Windows systems. No Linux based PC. So your excellent explanation cannot be performed by me. That is my point.
I now know how to do the wsjtx ¡ªrig thing, but that could be done prior to this new feature being added. That is because wsjtx can run on either Windows or Linux, nothing to do with the new QDX USB feature.?

No need for you to respond Ramon, I am just voicing my concerns.

Could you possible create a single subject line and continue to use it so I can mute the topic.? These are not the types of post I¡¯m interested in seeing here.

Hans,

?

Is the +9V/1A supply regulated?? How much voltage do you measure from it?

Subject: [QRPLabs] Another QDX went up in smoke

?

Yesterday, I ran my QDX for the first time off a 9V / 160 mA power adapter. You know, one of those things similar for charging your phone.
It was receiving properly, and I was even able to make some QSO's.

Today, I decided to use the same kind of power adapter, but this time a 9V / 1A version.
The QDX started out normally by flashing the led rapidly, then the led went off and smoke came from the QDX.

What in Earth may have happened here ?
I did not raise the voltage. The only thing that was new was that the adapter can supply more amps.

Any help would be appreciated.

Tnx,
73 Hans


Re: QDX won't load firmware...?

Rereading this thread, I too wonder what's going on:

  • I suspect that until you successfully load the QDX image, the terminal won't be available (e.g., it's part of the QDX image.)
  • If the (audio & com) devices are coming up, something must be working...

What happens if you try to talk to it with, say, flrig? Is there a way you can prove it's actually dead or alive? Would fldig or wsjt-x tell you if the audio stream was dead or alive? (Does the CAT test and PTT test work or not?)

Thank you. To your first point, I now think it is loading firmware OK. It goes into bootloader mode, appears on the desktop as a flash drive, and I can drag and drop the QDX image into it. Then it appears to be happy with what it received, because it reboots itself once it finishes reading in the firmware.

About talking to it with other apps besides the terminal mode, I posted a screenshot above from JS8Call, showing the hamlib error that it throws. WSJT-X shows a similar error, since they both use hamlib for rig control. I don't have flrig set up on this system, so I haven't tried that.

Again, the serial connection was working before, for the first few days I ran the QDX. And then, without me changing anything on the computer side, it stopped working.

The main hardware clue I'm chasing down at this point is that, in "normal" mode, the front panel LED just lights up steady the whole time. It is not doing the "Quick flashing (flickering) for first 5 seconds after power up" that it's supposed to (again, it?was doing that flashing before).

I have asked Hans in my support ticket what this non-flashing LED behavior might indicate, but I haven't gotten a response.

Re: #QMX firmware 1_00_004 #qmx

 

Thought so. Actually I prefer it because my other radios, mostly older Icoms, have CW on the LSB. Turning the dial clockwise raises the pitch of the incoming station. On the QMX or any rig where CW is on the upper side, clockwise lowers the pitch. When I go to move frequency I instinctively turn the dial the wrong way. I suppose that people who are used to CW-U would complain if it was the other way, which is why a selection is nice.?


Re: QDX quit working

 

Tom - agree with nw2w - Jeff Moore took care of one of my QDXs that stopped working suddenly. ?I had another QDX and QCX as backup and, due to work, no real time to troubleshoot. ?The process with Jeff was smooth and he kept me informed of what he did. Good luck. ?Jeff, AC7IJ

Yes, I know I can mute a thread but the thread title keeps changing.

Jeff,
Congratulations on the build!
At this point it looks quite good. Leave as is and enjoy!
Good luck on the portable ops. You're gonna have fun!

(QMX) Filters slightly out of band. How to adjust?

 

Still somewhat a noob when it comes to adjusting filters and such but after doing the 20m "#2" modification and loading FW: 1.00.005 I swept the filters through the terminal. 20 meters looks great but noticed 60, 40, 30 to be just outside and I'm not sure about 80 even though it looks similar to the image that Hans posted on his modification page.?

Is there anyway I can adjust these filters so at least 40m is within? Or am I splitting hairs here and it's just fine.?

As of right now this is my only portable rig which I hope to do POTA/SOTA with. So I'd like to know it's working well.?

Serial #176
FW: 1.00.005
20m "Solution #2" mod completed

Thank you!
