Yes you are correct of course.? C1 has no affect on power output.? I was actually hearing the local oscillator on another receiver and initially tuned for a maximum feed through because I couldn't

Rick, I've been reviewing and reviewing the pics and circuit and have come to realize that they are grounded to Q103. I think the danger has passed, thanks for the photos Giuseppe iu8eun Il Dom 20

Hi Rick, thank you for your optimism in thinking that the board can be recovered, the problem is that there are two circuit board tracks that passed under Q103, and I'm trying to understand where they

Ian, I have no idea! I get so frustrated trying to get these computer things to work that once it works and connects I go forth with the task and forget the sequence. I know it has to be COM6 once you

Michael, I just received a Talentcell TB1203000-USB 12V + 5VUSB battery pack, to power my QMX. Thomas Witherspoon K4SWL uses/has used this compact brick to power his QCX. I didn't even think of also

I'm trying to get WSJT-X v2.7.0-rc2 going with my QMX using 009 firmware. If I select Kenwood TS-440S then Test CAT works, the button goes green. Press Test PTT and it fails with a lengthy message in

Giuseppe, looking at your third picture, I think you'll be able to repair this board with no problem. I saw today Steve G4EDG's board with Q103 removed,

Hi Pedro, Based on the assumption that the Q1 labeled trace = Q8 on the schematic, that the Q2 label = Q10 on the schematic, and the other two devices = Q9 and Q11, then I believe that half of the

I've got a USB A to C cable that works, I have no idea where I got it, it's just one of several which I have around, possibly Amazon's cheapest. One way to check a cable is to use it to connect to

Not sure if this has been reported or not, but while using the config menu with Putty, I was trying to configure the bands middle frequency setting nearer cw frequencies as default on switch on. All

Basically, you are bottoming out the long male pins into the installed female socket. Hans shows a picture of the long male pins bottomed out in an uninstalled female socket, and mentions this on

This got me thinking.? Does the VFO/Signal Generator display...? 1) The frequency requested by the user 2) The actual frequency selected by the VFO/Signal generator internal algorithm and based on

Nic, to clarify, I imagine that when you're testing for continuity between Bl and Br, you are shifting the probes around until you hear the continuity buzzer. At this point, you have mutual contact

Hi, I've been using the QDX transceiver for a while, mostly in portable operations,, and very satisfied with it's performance. In one of the usages a bad connection of the antenna ended with no

During assembly I struggled with page 50 of the manual which has conflicting photos and instructions that appear to be not valid. I found the male pin plug pins were too long and needed to be trimmed

Hi Joan, In Germany I use a "ESD-Matte" and "ESD-Pinzetten" by Pollin Elektronik (Germany). I don't know the english word for it. You can search by Google by using this both words. So I think, that

Are you checking continuity between the cut ends of the wires or (correctly) between the PCB pads?? You can also probe between wire and its pad to further isolate an open joint. I haven't found

If your probes make good contact with conductive regions of the Bl and Br wire ends, you will see continuity. One of those ends does not have a good electrical connection to the board.

Yes Willie Just been watching a Vid re USB C Cables!! Nightmare. No, as I said I pinned the cable out from the A end to the microprocessor pins and the connection is there. If it were a charge only
