I'm in that group as well. And I was expecting to help Jason out with that project by admin'ing a group, but he's so far along that I let it drop.

Oh, I thought it was me. I have a subscription to the TAPRN group who has some folks
working on a SMT version.
Anyway I can help, just ask and I'll see what I can do.

Re: alternate build procedure for Mini?

Dave, I do tend learn a lot of things the hard way.
But life is short and sometimes it is worth asking a question.
I'll report back.
Thanks.

Re: alternate build procedure for Mini?
#qcxmini
Luc, thanks!
The blog looks very helpful.
My main concern was impedance mismatch.
I was hoping someone had some BKMs (best known methods).
I just planned to solder a piece of coax to the measurement points.

Re: Anyone Using a KXPA100 with QDX?
Sounds like a brainstorm in the making.... :)? What would be nicer than a 5 band CW rig that works this well?? A small switch to put the smoothing circuitry in and out for CW work?? I dont' know.??
I have listened to the signal on CW (sent via FLDIGI) through a local rx with attenuator on and it sounds pretty clean, but I have not had occasion to work anyone OTA yet.

Mitch, the biggest problem with CW on the QDX is there is no envelope shaping. You would experience key clicks.?

Re: QDX + Raspberry 4 sound problem
Fernando,
Looking at your screen shots of the Pulse Audio Mixer you have the volume controls all the way max. The Volume Controls should all be at 100%. Going over that is not going to help and may cause distortion.?
I see since I started this that you seem to have got thing working, but still the volume controls all should be at 100%, an nothing more for best results. Adjust the QDX output to be what you need with the mixer levels at 100%.

My QDX seems to work, both on reception and transmision when? used with WSJT-X and a Raspberry Pi 4. However, all the decodes I obtain have a very low signal level, much less than what I usually get with my TS-850. I have the feeling that the sound configuration might be wrong and I tweaked it in different ways, but I do not really understand what I am doing. I enclosed some screes showing the the settings and WSJT-X main screen.
Is there anything obviously wrong? Ehat should I check next?

Re: QDX + Raspberry 4 sound problem
OK, I will. Although setting the audio gain to 18000 more or less cured the problem. Best, ft.

Re: QCX WARC Party - November 2022
Hi Chris, nothing wrong with your cw. I was copying you fine - Hedon and Ferriby info - but then the QSB took your signals completely away and I didn't hear anymore from you. One more contact on 30 with Zdenek/OK2BQN so just two QCX - QCX qso's. 73 Dave M3PMG

Chronic? That depends, normal if you do not power cycle the QDX.

Re: QCX WARC Party - November 2022
Not a good session for me on 30m, sorry to say.? Late starting, was having a pleasant chat with M3PMG on his QCX but he disappeared (or maybe he got fed up with my rubbish CW), exchanged 599 with HA70FI then rig went dead.? Blown fuse replaced but too late to continue - heard OK2BQN just as the clock reached 1400.??
Hope others had better luck.? Back to building my next QCX mini.

Re: QDX ... Other modes?
#qdx
Making headway.? Basics are functional now.? What you see here is FLDIGI using the QDX as the sound card naturally.? Working on the message formatting.? Eventually we'll have these devices connectable to the internet via my AWS account (for dev and test) also.? Remote control over the device via internet in a web browser, with chat, presence, etc.? More to come.
Apply to groups.io group "qdxpro" to get in on the fun.

Re: alternate build procedure for Mini?
#qcxmini
Hello Mike
Just building a 40m QCX mini.? Fitted T1 this morning along with LPF components out of sequence to ensure I could check out the completed filter before doing anything else,?having experienced an issue on a previous project caused by a wrongly marked capacitor.? Sequence is whatever is convenient for the builder - just check you haven't got too many bits left over at the end!
I fitted L1 to L3, then checked them out for continuity before fitting C25 to C29.? I didn't cut off the leads from C25 and C29 immediately, but used them to tag onto 2 flyleads made up from a couple of inches of RG174 with SMA and BNC connectors respectively. I keep them for that purpose.? Saves getting solder in any hole I need later.??
Plugging in the nanoVNA says the filter looks fine, as expected.??
Just finished the 1300Z QCX QSO party session on 30m, cut short by blown fuse, so having fixed that, soldering iron on and back to the QCX mini.
Good luck with yours.
