Re: QMX + Backlight dimming
Maybe you can replace R306 (33 ohm) on the front panel board with a small 100 ohm pot to adjust the brightness. I was thinking of doing it for my QMX (not plus) not necessarily for the brightness but

Re: QMX+ Power Increasing Question
Thanks Hans, a self calibration feature would be great. My QMX+ is just under 1W on 6m and I would like a bit more, that is quite a lot under spec.. Thanks for all your efforts.. 73 Dave G4FAW

QMX + Backlight dimming
Does anyone have an easy safe method of dimming the backlight on the QMX+ Perhaps changing/adding a resistor. The bright backlight is fine in a well let room or outdoors but in my dimly lit bat/ham

Just tried this. After update, CW sidetone clicks like crazy. I had to set "S9 sounds like" to 9. It was at zero. Tony AD0VC ________________________________ Sent: Thursday, July 11, 2024 12:17

Thanks Hans, Always love seeing new firmware releases. Just a note that the href link to the operating manual on the QMX page is still to the 1_00_018 PDF even though the link description says it

Re: newby mistake,
My only concern about using a drill is with multi-layer circuit boards, it might be possible to disconnect the through hole connections. Dean - KC9REN

QCX Mini WSPR Without a GPS
While waiting for cables to arrive to hook up my QLG2 to my 30 meter QCX Mini, I tried WSPR absent a GPS in line to lock the clock. I set the clock manually via the onboard QCX Mini menu by watching

Re: QMX Rocks!
I agree 100%. It's a ton of fun and surprising the amount of DX that is possible given the conditions and the power of FT8. Since mid-May I have worked 23 countries and completed the 13 Colonies clean

Thanks for your reply Dan. I had considered shielding but before doing that I decided to take the time to run all of the diagnostic sweeps on all bands with and without the speakers sitting on the Dev

QMX Rocks!
I've been using my mid-band QMX for several weeks on CW and FT8 (mostly CW) and have had a lot of success, the majority of my QSOs coming with US stations. But today I ventured up to 15 meter CW and

Re: My QMX+ has a .3 ohm short on VDD
Dear David, Board tapping is a good method in finding an intermittent connection sometimes. I have done this with some success in the past. You might help narrow down the area using a narrow

Re: Defective PCM1804
That leaves me one idea to explore, but I'll have to build the kit and measure transients to check it.

Dear Greg. My resistance measurement comes and goes.... when it isn't .4 ohms it is about 2.4kohms... tapping the board makes it change.? I have gone back to the work bench and rechecked some solder
