Thanks Ron I managed to lay my hands on 2 HROs recently so the first Christmas job will be to get those recapped and realigned. I've run out of magnet wire so just ordered a selection on bobbins from

This seems to happen quite often while building the kits. And really it is a problem very common. Don't bend the PCB! This video might be of interest to you and the kit-builder-community:

Darn, missed it. Even before I build my QDX, will try to get in on the next one. We need something like this to get some good old JS8 ragchewing going - have had a few meaningful exchanges but mostly

Yes audio output is QDX digital.? It does work for some bands.? Same settings on tablet and works fine.

The W6SFM Samuel F. Morse Amateur Radio Club in Sacramento, CA would like to remind you that our Bug Roundup event will be held THIS Weekend! The Bug Roundup Event is a special time to bring bug

Yes, the 50V is the part used: it's in an 0805 package. -- Julian, N4JO.

With linux there are many solutions like using the RAW Io and having the program do the management work.? Modem programs were for that, same as some of the terminal programs. The trick or lack

Jason, here's a link to one supplier: 100v unit https://www.newark.com/tdk/c3225x7r2a225k230ab/ceramic-capacitor-2-2uf-100v-x7r/dp/87R4504 50v unit

It's possible that some coupling is happening even with the cracked chip cap but it's not going to be anywhere near its designed value.

N3MNT, I assume that you changed the QDX USB Audio to not be the default audio output device in Windows and that you went into the sound volume mixer and made sure that the QDX output was full.? I am

To augment Fred's comment: C2 is absolutely necessary: it's inline with the antenna, so without it the QDX is completely dumb and deaf. I'm not sure how you're getting any signal; maybe it isn't

It's toast. Replace it. If you can fit a leaded component in there... That will work too. Fred W0FMS

Hi Ted. Yes I have done this. Since you are going down to 40 meters, don't forget to also add the 39 pF (390) capacitor in position C5. It won't have one there for the 20 meter version. You got one in

Some additional testing this afternoon.? It appears that the issue of not keying the TX when using windows is dependent on the machine.? I am unable to key the QDX except on 40M on one laptop? but

Folks at home, I built the QDX kit over the weekend. Enjoyed every moment of this build. The error occurred when I got to section 2.16. I was fitting the wired axial inductor in place as per the

Hi Alan, Indeed it could be either but only Hans can say how the design is supposed to be. Anyway, my filing worked so I am happy. 73, Gregg W7GRM

Gregg, It is certainly offset on mine. IC7 is almost flush with the edge of the board. Plenty of clearance for IC6. The break-off cuts are not precisely aligned. I do not think it is designed for the

I was surprised to find that mine was only just adequate. Dropping the WSJT-X slider down just 2dB resulted in no TX. 73 Alan G4ZFQ

Was monitoring JS8 for an hour or so, rx only. Then this occurred: so I clicked on the TUNE button to go into transmit briefly, then toggled it back to receive and all was well. Vertical lines are

Converting bands is, practically speaking, no different to replacing faulty components. You've already addressed the concerns, and suggested perfectly valid mitigation strategies. Go ahead as proposed
