Hello, Allison-- I second Mike McCarthy's plea regarding your exit from the QRP Labs group. Your contributions are consistently worth reading-- and pondering! 73-- Brad AA1IP -- Sent from Postbox

Hi all, It was very nice to meet Hans in Friedrichshafen ! Tomorow June 27 is the regular QCX Challenge , see https://www.qrp-labs.com/party.html I will not be QRV since we're travelling, but you may

My findings: No power at all at the BNC upon transmit. Continuity from the center of the BNC socket to c29 is good. Checked the capacitors involved in the transmit circuits, no issue. In receive, Q6 h

Working FD with my QDX this year. So far the solar panel and battery are holding up. It is definitely QRP but it works.

Hi I have built QDX version 3 and it works fine on 80m (4.86W) and 40m (3.69W) but I am getting only about 0.8 watt on 30m and 0.23W on 20m. These powers have been measured with a spectrum analyser vi

Hi All I was wondering if there is anyone out that would be willing to look at a QCX+ for 20m, I just built. It is working as far that it turns on and goes the intro and then it switches to the 20m fr

I re-send my old topic because I didn't find a solution. I was very surprise because DC voltage at input pin 7 and pin 9 of is higher than 2.5V (about 3.6V) . I unsoldered these inputs, of course the

Hello: I just built a QCX mini. Almost all seems well. My sidetone is clear and pleasant audio when I listen through headphones while keying the QCX mini. However, when I listen to my sidetone on a ne

Hello: I just built a QCX mini and almost everything seems great! The only problem is a buzzy/raspy sidetone. It sounds perfectly clear and pleasant in my headphones when I transmit, BUT on a receivin

The following post is a corrected message. I got some of the numbers wrong, I was in a rush. Got it finished off and the only problem is I get an indicated 2.3w with 13v. If I turn my power supply all

I was in QSO on JS8Call when suddenly it quit working. The LED is out, and while I don't SEE any components obviously split or burned, I can definitely smell it. Any suggestions on where to START? fee

Hi there, I built my QDX for 9V but used the 12V regulator mod form Dan, NM3A (#84119). The Voltage regulator is screwed to the center of the top-case and I used an extra aluminum cooler on the finals

Hi Jon How can we (the group) help? 73 Roger 8P6RX --- *************************** Roger Hill *************************** Links: ------ [1] https://groups.io/g/QRPLabs/message/87636 [2] https://groups

Hello I received and mounted the QDX version 3. I don't need to worry about the driver configuration problems under W7, I'm better off with Linux under Mint 20 Cinamon. I use wsjtx and JTDX , under li

Hello, After a burnt of the old LM1117 regulator, I changed to a 78M05 and lot of other components (uP, diodes, Si 5351, 74ACT00, LCD, and the 3 BS170) I am blocked on the FST3253. When I have a signa

I did a quick scan of the filters and was disappointed. Maybe someone here has seen this problem and knows what I did wrong.?. All bands seem to be peaking too high. Need some help please. Thanks, Ric

Hello All, I am following the various discussions about the shapes of other users' filter sweeps with interest, as I am unhappy with mine. I do not find the sweeps as useful as I would wish, however.

I'm looking for a STL to print out a case for the QSX. I have the aluminum case for the one I've already built, looking for something different for this next build. Anyone have any ideas or leads?

If this has been addressed already in this forum, I'd appreciate a pointer to the thread. I've built the Rev 3 QDX. The build went fine and it really works fine "out of the box". Been using JS8CALL su
