Martin, Thanks for the note. Maybe next time the conditions will be better and we will be able to have a QSO. Ed AB8DF

Hello ... After installing 004, successfully, I've got 3 new com ports, 3, 9, & 10. All of them allow CAT control of the WSJT software. Decodes are happening and I have made a number of US and DX

Another excellent idea, Jim. If I can’t find those special TRS jacks, I’ll do exactly that ! Thanks much ! 73, Jamie WB4YDL

Thank you for the description, Ludwig, I now understand how the controller input may be limiting this voltage.? For some reason I wasn't thinking about it correctly. So there probably isn't a problem

Stan, sorry my text was a bit short. VDD for the controller was round 3.0V. With the higher 3.3V at ADC_3V3 the difference from ADC_3V3 to VDD is 0.3V, maybe limited by an internal protection diode.

Yes, Ludwig, I forgot about the possible effect of the A/D input. But the measurement he stated at Q111 was 10.6V and 3.3V on ADC_3V3, so the difference would be 5.3V - 3.3V = 2.0V, which I don't

Two issues that I have reported before are not fixed in 1_01_004 and that is OK. I just wanted to make note that I had tested them and the bugs, as expected, are still there: 1. With VFO B selected,

It can’t have failed open circuit as the 12v rail was being shorted to ground. You can check that it is working by looking at TX voltage on the diagnostic screen. It should show 0V in RX and

Hello Allan & Hans Thank you for taking the time to reply. I can see from the group messages that you have a few other irons in the fire! My interest in the QDX-M is in building a few for our radio

Hello Jean, same problem here. Please read /g/QRPLabs/message/143760 for Hans answer. (He wrote about Win7 not Win10). 73 Ludwig

I did some investigation on persistent port naming on Linux some time ago https://sipsmi.wordpress.com/2022/12/13/multiple-flrig-with-persistent-device-mapping/ - read here. This should work with

Hello Hans, I'm on Win7 and just finished my QMX+.? The QMX does appear in the devices list but says it is not connected. I've got the STM drivers but something is not right... -- Jean-Jacques -

Fine here too: Same Audio designator as before and same COM22 plus the new COM16 and 18, which were previously unassigned. I have 4 QMXs and I just need to make sure I plug them into the same USB hub

Awesome, thanks Hans! 73 -- Matt N3AR

Hello Matt I have never owned nor any radio transceiver other than homebrew and QRP Labs radios. So I mostly have no idea what they do. But yes, in QMX, all three Virtual COM ports are completely

Hello Hans, thanks for the quick response. Exactly this came in my mind but I didn't know about the effort. And it looks like a thing of old Win7. Changing between a QMX with FW03 and one with FW04

Jamie: oops, I mixed up C17 and C16.? What I should have said was that as another PTT option, you could add a SPDT switch.? The switch common is connected to R6/C17 junction (with that leg of C17

Hans, I use a mid 2011 21.5" Mac running OS10.13.6 High Sierra. Using "Terminal" I have operated, at various times, two QDX's and a U4B and all 3 are identified as /dev/tty.usbmodemFDxxx xxx has
