#QMX+ ongewenste eeprom initialisatie
Beste om's
Als ik bij de qmx+ gelijktijdig bij gigantische de pwr en menuknop indrukt "intialiseert de setup Eeprom", alle instellingen zijn weg, is dit een bekende feature? Of een bug in de firmware 003?
Wanneer dit is gebeurd, moet de kalibratie ook opnieuw worden uitgevoerd?
Waneer je snel naar menu wilt is dit een verminderde vermindering.

Hi all
I updated the?SSB?beta?testing webpage of the brave, here:??and
released?firmware?version?1_01_005 to it.?
There are TWO changes only.?
Firstly, I have made many changes to the SSB Calibration (phase pre-distortion self-measurement). These improve the robustness of the calibration. I made changes both to the way the calibration itself runs, as well as searching different configurations
of the radio while running the configuration. On my QMX+ here it now runs from 160m through to 6m and completes all successfully, with the very minor exception of 160m which only gets as far as DAC 2300, so *almost* there,?just not quite and it won't matter.
All others run all the way to the end (DAC 2600 or so, on a 12V supply). Additionally I applied a little?Chaikin algorithm smoothing to the curves. You will notice some additional debug information printed on the screen on some bands on the terminal version
of the calibration and the calibration will take slightly longer; this is the system trying to determine feasible calibration configurations on "difficult" bands.?
Secondly, I have added a configuration in the System Config screen (accessible on both the terminal and the LCD). This is a "list" selection so use the left/right arrows to select a value in the terminal, or the Tune rotary encoder to select a value when
adjusting it on the LCD. The possible values are:
- USB Audio sound card and ONE serial port, as previous configurations
- USB Audio sound card plus TWO serial ports
- USB Audio sound card plus THREE serial ports and potential future USB Flash drive
Only the third of these makes use of ghost USB endpoints.?
Note that I also discovered an error in the USB Hub Device Configuration Descriptor in the area of the potential future USB Flash drive. On my Linux system it just worked anyway, but it's possible different Operating Systems are more fussy. I am very curious
to hear, particularly from people with Windows (even Win 7 Ludwig), what you experience for each of these configurations. Even if you already tried it on 1_01_004 please try again which each configuration in 1_01_005 as it will provide very useful information.
They all work here, but my system is Linux.?

Re: QCX-mini LCD top row is blocks, bottom row is blank
Thanks Ron, I re-worked a few solder joints and was able to bring things to life. Performed alignment and places in case, but now have a couple of other issues to troubleshoot. 1) on power-up, LCD looks normal but text slowly dims to nothing and no functions work. Power-cycling right away brings up LCD with no text and no function. Waiting a few minutes to power-cycle brings up LCD with text which then dies away as before. 2) I performed a factory reset to see if that would help but now on power-up I have a LCD that is not lit but has text 'use original ic' and no functions work. I can see this is going to be a journey!

I just finished my first kit, the QCX Mini. I have very little experience with soldering, other than a few arduinos and such, so I'm pretty new to this.
?
When I go through the alignment steps I find that the BPF readings are very low, around 3-4 max. I've checked continuity on T1 legs and they appear to be fine between each pair. I did heat them up again just to make sure the enamel was burned off. A strange behavior I have found is that if I apply a little pressure on the display board towards the top edge of the screen or bottom edge, as indicated by the circled areas in the picture, the scale goes up to 8ish and is adjustable. I tried a hack to test if this made a real difference and wedged a little bit of paper in the spot, while in the case, to see if it held true but it didn't. Before I desolder and rewind T1 is there something else I should check? I do not own an oscilloscope, only a DVM.

Laptop computers often have power saving features that can be configured to turn off some of the power hogs when they are left unused for a while. You might look at your power saving settings, and change them to leave your USB and com ports turned on. -Chuck Harris, WA3UQV On Fri, 25 Apr 2025 01:11:33 -0700 "Chris, G5CTH" <chris.rowland@...> wrote: On Thu, Apr 24, 2025 at 10:42 AM, Richard Dyer wrote:

Hi Hans,
?
Is there a maintained Feature Request list available somewhere where we can check if what we¡¯d like to see has already been asked for, and perhaps add a vote?
?
I know posts can get lost in the volume, and I expect that is why there was no answer on my question on having variable TX power available as a setting ( /g/QRPLabs/message/143397), but I don¡¯t want to bug anyone, so if there was a tracker we could look at, it might save you getting duplicate requests or being bugged by people like me :-) ?
Love the pre-built QMX, am going to get a QMX+ kit to have a go at¡

Last Sunday I made a couple of SSB contacts on 20m with my handheld QMX and the EFHW antenna, using the inernal mic only.
?
I also joined the net on 14.300MHz to ask how I sound over SSB. I got 58 from CA to WA and the net control said my audio was good. So I guess the internal mic still works okay as it is, without an external mic?

Ok, replaced Q102 and D109 and at least the symptoms are different, but still not working.
Quick synopsis here and I'll start documenting the waveforms and voltage levels.
Replaced Q102 and D109 (Q111 drain still lifted) and tried powering on. I could see a nice waveform out of Q108 and Q109 now, but they would drop after 2-3 seconds. I think the processor gave up on 3V3 and dropped LIN REG EN at that point. Since Q102 was no longer a shorted device, everything shut down.
Got brave and reconnected Q111.?
Now I still get the nice waveforms, but LIN REG EN stays on probably because ADC 3V3 is sitting at 1.4v. And the source of Q111 is 3.8 so we still have that mismatch. ADC 3V3 should be reading 1.9 based on 3.8 at Q111.
It is drawing about 210ma at 7v.
So, with that I'll go into full measurement mode. Unless someone says "oh, well in that case it has to be x".
?
Again, thanks for all of your insights and to Hans and additional contributors to the excellent wiki collection.?

some of them do use very poor quality electrect mic capsules.

These poor quality capsules usually result in muffled audio (lack of HF response

Cure is to replace the capsule for a few cents if you are unfortunate to have one.

Oddly enough, the worst offender of late is a Baofeng branded hand mic in the style

Re: QCX-mini LCD top row is blocks, bottom row is blank
jeremy, you should check for continuity between IC2 Pins 2,3,4,5,6 & 27 to LCD pins 11,12,13,14,6 & 4 respectively.? If any are missing check soldering on the LCD, IC2 socket, and pins and sockets on the connectors between the main board and the display board. Those board interconnections are where most of the soldering issues occur. Good luck ... Ron
So this indicates the LCD is receiving nothing at start up
?
Unsoldered /shorted ?connections, ?CPU absent, CPU wrong way round, pins folded underneath etc are all worth checking?

Have you read the troubleshooting guide on the units webpages ??

Re: QMX SSB : Does a Baofeng Micro works ok ?
Angelo,
There are a number of different factories that produce microphones for Baofengs.? I have bought 6 of them so far and everyone is made differently. I had one that didn't work at all on the QMX, so I got the mic element from DigiKey that Hans mentioned on the QRP Labs website, and replaced the one in the Baofeng mic with it. I found that another Baofeng mic worked just as well as that mic element from DigiKey. I did have to cut off the connector and rewire a new stereo connector, so the ring to ground is the mic connection, and the tip to ground is the PTT connection. I just isolated the speaker wires and I'm not using the speaker. It is only 8 ohms anyway and the QMXs work better with at least 32 ohms.

Since I still had a 5V SMPS board available, I decided to try installing it in the QMX along with the 3.3V SMPS board and turn it on. At first, I only used 7V and limited the current to 200mA. And it's hard to believe, but the QMX works.
This means that the 3.3V SMPS board is not defective despite the burn spot visible in the photo. I was able to scratch it off. So it's probably just a piece of the capacitor that burned and fly off.
Then I tried it with 9V and a limit of 1.2A. That also worked without any problems. The diagnostics screen displayed the following:
?
?
I can't see anything unusual when transmiting either:
?
?
The current consumption was 140mA when receiving and 850mA when transmitting.
How do I proceed now? The QMX works, although the resistors on the mainboard without SMPS, control and display board indicate a fault:
PWR_HOLD to GND: 242 ohms
ADC_3V3 to GND: 9.5 kOhm
VDD to GND: 461 Ohm
?
I could explain VDD by saying that there is a solder bridge somewhere that I cannot find. But PWR_HOLD and ADC_3V3 only lead to the MCU. Can anyone explain this?
?
