Figured it all out, it was FINISHED doing the calibration but gave no indication that it was completed. I got PUTTY working and was able to see what was happening and then realized that the

Nice! I had similar thoughts, and now plans to try mine with a Milwaukee battery I have. Thanks for sharing. -Nate N8BTR

I was wrong! I just setup NaP3 and everything is working exactly as advertised. I have a lovely, wide, panadapter and the front panel audio is working for CW bandwidth. Need to tweak an offset or two,

There is a pre-release here if anyone wants to play with it. It assumes you have a Java run time environment installed. https://github.com/sipsmi/qmxwidget/releases/tag/alpha-0-1

I'll say it first...you might have already blown the finals, not having the load connected. 73 Frank

They are 6 mm long, but the thread inside looks deep enough for an 8 mm...6 is plenty long enough -- Jean-Jacques - F5IJO FISTS#17008 LICW#5902

FWIW, I removed and remade T507. I had made it with wires B and C being jumper wire, not actual magnet wire. It's now rebuilt and reinstalled, solder joints confirmed, but still now Power.

Hi Andreas. That issue you had with the fuses most likely deleted the EEPROM file. That file is proprietary and not published. You will probably have to order a new chip from QRPLabs to get going

I have been getting USB device errors until this morning and fairly sure the QMX was not drawing any current. But this morning noticed it was using abt 50ma after firmware update shutoff the backlight

Did you install the jumper at JP501, behind the BNC connector? Roger ?Get BlueMail for Android ?

Ok. Then I am not the one you need. Over to the other experts! Roger ?Get BlueMail for Android ?

Hi everyone, I recently completed building my QMX kit and it seemed to go well on the surface. The unit powers on just fine, the display works, menus respond, and voltages on the 3.3V and 5V SMPS look

Hi, I try to upgrade the firmware of my gcx mini, and mess up the fuses. after I corrected it to avrdude -c usbasp -p m328p -U lfuse:w:0xF7:m -U hfuse:w:0xD1:m -U efuse:w:0xFC:m It shows the use

Hi Glen Assuming that's a 20-10m QMX that just means it's finished.... You can press the right button to exit out of calibration. 73 Hans G0UPL http://qrp-labs.com https://buymeacoffee.com/g0upl

Starting from a non-SSB version, I just installed 1_02_000 on my QMX and ran the SSB Calibration process directly from the QMX (no PC). The display shows " *10m L SYNC, Optimum 46* ", and has FROZEN

Jerry, could you use a microcontroller to speak CAT to the QMX and read the band info that way?

I have the dummyload from QRP Labs, which has a + and - for measuring, but I still get 0.0 volts. (checked AC and DC, just in case...)

Update: Visual inspection showed that Q108 was broken as it had its case cracked. Cannibalized another unbuilt QMX+ board and replaced it. Measured and found D108 shorted and replaced it as well. Now

Nice picture of a great day! ?I really enjoy people’s adventures with QRP radio. -- Trevor (N0YMA)

So you might have a problem in the power sensing area (T507 I think). Do you have a dummy load, or any other way of measuring output externally? Roger ?Get BlueMail for Android ?
