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!

Re: QDX IC7 fouls case
#qdx
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.

I also have gas discharge lightning protection here. It's probably not going to save anything with a direct (or even nearly so) hit, but it will keep the static from building up too much. Anyway, I haven't lost any equipment yet.

I have the gas tube lightening arrestors on my EFHW antenna. So far, so good...

Re: QDX Isues with sWindows10
#qdx
Hi Evan,
Ok, on your cables and laptop swapping. You turned off the USB sleep in the Windows Power Settings, right? It is a bit buried in the menus there, but potentially your USB connection might be going to sleep? I have mine set to never sleep. FWIW I have a very aggressive anti-virus watch on my laptop¡?

I have tried changing bands, even power cycling the QDX.? Something is causing an issue that it takes a couple of resets to make work again.
BTW, I let the QDX connected to the Raspberry Pi 4 run all night, and it is still decoding on the active bands.

Re: QDX Isues with sWindows10

Evan
? I found on Windows that often I have to go into WSJT-X settings and reselect the QDX audio. Even though the settings show QDX choices - I don't get a signal until I select the QDX audio input and output yet again.
? Also - in Windows if you right click on the speaker and select "sounds" to get the sound window? then select recording device tab and select QDX properties you can select "listen to device". Then from the task bar select you actual speakers as output and you can monitor the QDX receiver output.

Re: QDX firmware 1.01c with aids for debugging no-transmit-RF issues
Hi all,?
As well as a band tx inhibit modification (I too don¡¯t have a resonant aerial for 30 metres or for 80 meters) an output to indicate what band is in use would be nice. Then I could use it to switch in an appropriate matching circuit.?
Brilliant kit.?

Re: QDX - RX and TX stopped working on 80 meters only
Thanks for the responses
?? As stated in OP, I'm using firmware 1-01.c - the three blinks should indicate that the QDX thinks it's transmitting. Also the current draw increases so something changes when it goes into transmit.
?? I did try a dummy load - no joy
? Evan - I'll try checking the diodes in the LPF. The thing that really got me is that receive is also dead, as in 0 db shown in WSJT-X. There are entirely different circuits selecting the BPF and LPF and both stopped working.

Re: QDX issues: please include info:
#qdx
Please,
Tell me like ¡°NanoVNA for idiots¡±, as you would tell a child, how I use my NanoVNA to measure accurately the uH L values for the inductors going into my QDX.
I might be able to figure it out on my own but might screw it up and if you know how to do it right, it sounds like it would be worthwhile.
thanks & 73
