That is a very nice idea!!!? I will definitely give it a try! I guess the obvious is so easy to see that you can't see it.

Re: QDX Isues with sWindows10
#qdx
Gregg,
Thank you again for the tips.
I do not know what changed other than I reset the QDX 3 times, ran on battery power,? and was able to receive and decode signals on all bands.? I had tried on battery before, but the Raspberry Pi was on the shack 13.8 volt supply.? I did leave the PC and QDX running for the last couple of hours and the QDX is still decoding.? I also made two contacts using it.
Again, no explanation other than now it seems to work.? We will see how long it continues to work.

Hi Mike,
This is the type of magnifier I use although I didn't buy it off Amazon.
https://www.amazon.co.uk/Headband-Magnifier-Magnifying-Jeweler-Lights/dp/B08THRR7X1/ref=sr_1_7?keywords=head+magnifier+with+light&qid=1636831418&sr=8-7
Hans is seen using one in his video on tuning the LPF on a QCX. They are really good, although take a little bit of getting used to at first. There is a swing down high power lens on the right side which is very handy and saves using a loupe lens.
I have a "3rd hand" device with a couple of crocodile clips and a magnifying glass attached. They are O.K for some jobs but are nowhere near as good as the ones I have put the link to. They are available on Ebay and various other places and I reckon it is one of the best things I have bought in a long while....? apart from the QCX+ kit I am currently putting together. I have two QCX and now two QCX+ (including the one being worked on) the first three were built using a jewellers loupe at 20* magnification. This time the "Head magnifier" makes everything a lot easier.

Re: JS8 QSO Party this weekend
Al, If I see you on, I'll respond. You are a good stretch from my QTH so 20m would be the best chance. 40m seems weak here right now. I have only listened to JS8 so far so there is a good chance I would screw up my first transmission attempt anyway, ha, ha!
73, Gregg W7GRM
Gregg,
Looks like a good variety! I'll add @QRP and @QRPLABS to mine. Don't have the QDX yet, but I do have 4 QCX's and a couple of U3S.'
I'm going to try using the RS-HFIQ rig I have that pushes 4W today on JS8Call.

Re: QDX Isues with sWindows10

Hi Evan,
Ok, well if you want me to check any setting on my Windows 10 laptop, just let me know. Per your question in another thread on how to listen to the QDX signal, you can do it from the Windows Sound Control panel. In Sound Settings -> Sound Control Panel ->? 1. Pick the Recording Tab 2. Select QDX Transceiver 3. Click Properties 4. On the List Tab, Choose Listen to this device

In the process again we had issues with connecting his Windoes10 laptop PC.? We went to the Raspberry Pi and had to reboot 3 times to get it to connect with an audio signal, the CAT and even the input bar reported that it was working on the first 2 tries.
Based on that experience I went back and tried the 3 reboot tries with the Windows laptop and now it works.? I have left it running to see if it can duplicate the Raspberry Pi time of 12 hours continuous receive.? I did note that this time I ran the QDX on battery rather than one of my shack 13.8 volts power supplies.
I searched in the log file of the QDX and did not find any errors, so it is not an error that is reported in the QDX log file.
Will keep trying

Re: QDX issues: please include info:
#qdx
John,
Thank you, I have done that in the past.?
The issue is how to do it in the field where I would not have the rig.? I would use my ZM-2 manual tuner when I work out how to hear the signal at the same time that I am connected to the QDZ.? I did read a post on how to do that here somewhere.? I may also try it with the signal level bar to see how that works.

I do not have an antenna for 30 or 80 meters that does not require a tuner and am not comfortable in using the output of the QDX to trigger the MFJ auto-tuner that is required for the Ultimax 100 random wire antenna that I do have for 30 and 80.
Evan, you can use your main rig to trigger the autotuner. Once its found a match on 30 or 80, swap the main rig out for the QDX. It will see a matched antenna at that point. ? -- John AE5X

Here is the link to the thread /g/QRPLabs/topic/86737876#74070Hans said in this thread that it would be a few weeks before the parts would be ready for another round. I think that the timing would be around Christmas to early next year

Re: QDX IC7 fouls case
#qdx
Fyi, I tried all orientations of both sides of the case and none of them would fit for me. It appeared that the board cut from the panel had more clearance on one side compared to the other. It ended up being an easy few minute fix anyway.

Re: QDX issues: please include info:
#qdx
I connected the QDX to a 20m ground plane vertical which I tuned precisely to ft8 frequency and rf filter sweep is still looking wierd and same,? but QDX works perfectly.
I only have been able to do full qso's with Europe and Russia but psk reporter shows I've been heard even from Fiji ~16000km's away. So short message: Probably something is odd with the rf filter sweep graphic it self, but the QDX works all ok.

Re: JS8 QSO Party this weekend
That sounds like a good idea, Al. I am not familiar with using Groups in JS8Call but I assume we just add them to our settings and it will work? Like this?
73, Gregg W7GRM
Any thoughts about having an "@QRPLABS" or "@QRPQDX" callsign group?
I've been lurking on JS8Call's 40m frequency. It's good to see Hans getting behind JS8Call, I see a lot of heartbeats but not much traffic. I hope the popularity of QDX will get more hams involved.
Thanks!

I had this problem,but trying the pcb into both housings from both directions I found one ?combination where the pcb just went in perfectly. I have even seen someone on here file down the offending IC !! Not on.

Re: QDX TX power was almost zero.
Dear Syuji,
Thanks for this post, I to have low power on 80M 40M, 30M , but 20M is near normal, if the capacity of C2 had gone down this would explain it, I will test mine and let you know. (I have not disturbed L1 yet, I wish to measure harmonics before and after the inductor replacements)
Very Best Regards
Andrew
PS the Elecraft K3 10 Watt version suffered from this, the 100 Watt PA bypass capacitor used to go low and give the same low power fault on low bands, this was hardly ever spotted, as every Americans always bought he 100 Watt version! some caps to not like 10Watt, if they are going into an ATU when the aerial is mismatched.

I use one of these things:
It holds the PCB in the spring-loaded clamps and the width is adjusted with a thumb screw on the lower slide bar. I like it because it rotates, so you can put a thru-hole component on the board, and rotate it easily to solder the other side. I find it harder to do the front-to-back flip with a third-hand tool.
