Turning the rig on shows 1_00_027 as the version.?
I initially set it to CW and then Practice mode. After I installed the USB cable, I could turn of the Practice mode via the Menu but cannot change the mode to Digi now using the mode knob. It is stuck at CW. Band change does not work either but I can switch the rig on and off without any problem. I tried tightening the knob a little away from the rig to no avail.
On the computer side, I use Windows 8.1. In the device manager when I turn the rig on, I can see "QMX transceiver" under an "Other devices" submenu. When I double click on it the screen says its drivers are not installed. (I had installed the virtual com port previously.) When I try the "Update Driver" button and direct my PC to the relevant folder, the computer says the driver could not be found.
OTOH In WSJTX Audio tab I can select "QMX Transceiver" without any problem. In radio tab selecting Kenwood 440S or Kenwood 480 both return a list of errors in testing the CAT. My PC sees only USB as the serial port. PTT is set to CAT BTW. Changing Transmit Audio Source from Front/Mic to Tear/Data does not help either. Interestingly I cannot revert this setting.
A photo of the errors screen is attached.

Has anybody got a solution to my problem?

Maybe you installed the special driver for Win7 and Win8 (see the link above)? If yes, sometimes a driver "update" is to be done like described in the QLG2 document (see link above). Some times ago it worked for me.

And did you go this way:
- start PC and Win
- connect USB to QMX
- switch on QMX (only here the QMX offers the serial port to Win)

Thank you Ludwig. I have already done those.?
Furthermore, I had also tried updating the firmware, although not necessary, to see if the PC-rig connection is working. QMX+ was connected as an external device without any problem. To cancel the whole thing, I turned the rig off. The screen was already dark so I tried turning it on to see if it would go back to normal operation; it was still dark. So I pressed the button again to make sure it is off. When I disconnected the USB cable the PC binged to warn me that an external device was disconnected. That meant the rig was still on and in firmware update mode. To make sure the rig is shut down, I disconnected the power cable and connected it again. With the cable removed I turned it on and it went back to normal operation, still in CW mode.
So, I have got a feeling the problem is with the QMX+ On/Off button not responding to Mode and Band change clicks.The fact that it got stuck in firmware mode (i.e. not responding to OFF click) when connected to my PC is probably another sign that the problem is with that button.

From the operational manual:
In the firmware update mode, the LCD backlight is OFF,
nothing is displayed on the LCD, and none of the buttons
or controls or connections are operational,
There is no way to switch off from firmware update mode by using the encoder button.
So, I have got a feeling the problem is with the QMX+ On/Off button not responding to Mode and Band change clicks.
If you are able to switch off by long pressing the encoder button than the hardware should be ok. Click, double click and long press are going the same way to the controller.

Thank you Alan. The drivers are installed properly now.
And thank you Ludwig. I can see the audio drivers, too, after following Alan's instructions.
However I, still, cannot change the mode nor the band.

Test CAT returns OK now but now Test PTT is RED. I presume this is because WSJTX expects the rig to be in DIGI mode. Because I cannot change the Mode nor the Band. I tried a Factory Reset, hoping it might solve the problem, 3 times. It did not work. Interestingly after the first time the Band changed from 30m to 80m, and after the second time to 160m but I cannot change them myself.

This is strange and seems contradictory.?
The button on the left encoder connects to the QMX+ main board to directly switch the power on (but not off), and also to the processor so the firmware can monitor the switch (via Q202 and R206, R209).?
If the processor can see the switch state to turn the power off, it should also be able to see the switch presses to change modes and bands.? That is what seems contradictory.
?
Perhaps the shorter clicks would not be seen if something was wrong (poor solder, etc) with Q202/R206/R209, or if something else is dragging on this signal line.? I would check that part of the circuit card carefully under high magnification.? And measure the voltage on the drain of Q202 when switch is pressed and not (should be about 0V until switch pressed, then go up to almost 5V).
Or perhaps there is a fault in the encoder itself, such that it requires a longer button press to make proper contact.? Maybe try making your 'short presses' a bit longer and see if you get any response?

Test PTT turns RED when you activate it to remind you that TX is on.? That is normal.
You need to check if it is working by looking at the QMX+ display and seeing if the PTT 'dot' shows up under the A (or B) VFO indicator.? And yes, this only happens in QMX+ is in digi mode.
?
Make sure in the WSJTx radio control panel that 'mode' is set to 'none' (that isn't your mode problem, but can cause other probs if set incorrectly).
?
As a possible work-around, until you figure out the left encoder button issue, try sending the mode command via CAT as follows:
- close wsjt-x
- open putty and go into the QMX+ menu
- choose "PC and CAT" then "CAT command test"
- at the bottom of the screen on the "Command:" line type MD6 and hit enter.
That should switch you to Digi mode.?? MD3 to go back to CW, MD6 for Digi.
Then go back to WSJTx and have fun.? It should be able to change bands for you.

Thank you so much Stan. This did solve the problem to a certain extent. That is, once I change the mode to digi using Putty as per your instructions I can control the rig via WSJTX without any problem, changing band, etc. and yes, the dot appears under A, too.
Furthermore when I click the encoder knob the rig goes into CW mode too. However it then gets stuck in that mode and I can change neither the band nor the mode, unless I go back to Putty. Interesting in deed!

Found the culprit:
I dismantled the case. Wiggled the front cover a little and the encoder started acting normally. Screwed it back, the problems returned. I think one or two of the 90 degree pins is/are not making proper contact with its/their counterpart(s) inside the black plastic casing. The problem now is, I do not know how to solve this.? 14 Oca 2025 Sal 13:02 tarihinde ta2rx bekir via <ta2rx.bekir= [email protected]> ?unu yazd?:

Several of your joints look under heated and I would revisit them for a few seconds each to flow the solder. A bit of liquid flux applied to the top would enhance the solder wicking and adherence to board and pin.

Thank you Dave. I checked the bottom of the right angled pins and they seem to be soldered perfectly. However I cannot say the same thing about their counterpart in the black plastic casing. The one furthest away from the white plastic nut seem to be sitting a little angled. I think that one is the culprit. I am not good at reading shematics. If someone can tell whether that is the one connected to the on/off encoder than I can be sure. See attached photos.
Hans had warned about aligning these properly in the manual but it seems I could not manage to do it with at least one of them. :'(

Bekir,

ONe thing that could have happened, is if you soldered that right angle connector while the mating connector was plugged in to it, the female side of the connector, the one soldered to the main board might have sprung its contacts.
The gold-plated parts are very thin and if you heated them while they had their male counterpart plugged in, the spring part of it may have actually straightened out a bit or even moved away from the pin that is was in contact with.
If you soldered those parts in while not mated to their counterparts, disregard everything I just said...

Frank,
I just remembered: You are right, that was what I had tried initially. When I was told I soldered them the wrong way around, I sent the board to someone who could fix all my faults.
