Hi, Just purchased this great enclosure for the Z4-KX buck module which is popular with QRP stations & makes a great supply for qrp labs units. USB 3.0 PD and XT-60 connector inputs. Great supplier, C

Built the QMX as soon as I got it home from Dayton. Built both the QCX-mini and QDX digital previously without any problems. The QMX will not power up. Tried troubleshooting it with my limited skills

Well, I had a friend pick me up a brand new QMX at Dayton. I waited for the build instructions, and then built the rig (I've built many kits over the years and a couple of QRP Labs kits more recently.

Hey Hans and the gang; I finished up my QMX (serial number 100) on Tuesday evening and added in the ALPHA firmware load the following/yesterday evening. Here's my list of "Mis-Steaks" (including sugge

Can an assembled QCX Mini have the TCXO unit easily retro-fitted? -- William, k6whp -------------------- "Cheer up, things could get worse. So I cheered up and things got worse."

I completed a build of the QMX this afternoon. Before I knew that a firmware load was available I tried connecting power with headphones plugged in and noticed a pop when I applied power and the LCD d

I was wondering if the QDX kit ships sooner than the pre-built ones? It is hard to discern based on the wait list as it does not show what is a kit, and what is a built version. Thoughts?

A new chat has been created: Good evening all My QDX HB has been working well, acceptable output on all bands, although a bit low on 10m. Then without warning the OCP was tripped, and now the receive

I have finished my build, although I have not fired it up yet. A few comments: 1. This is by far the tightest build I've ever done. The toroids are really squeezed in there. However all of them did fi

When published I had a color manual prepared for the new qmx. I am seeing posts of errata to the original manual. Is there a source for these changes so I can change the original manual?

The QMX was so unexpected - at least by me. And it has, I think, some strokes of genius in its design. Firstly, Hans made it difficult for himself: the decision to fit it all inside a QCX mini case. F

I have recently packaged up a QLG2 plus a ProRock 2 into an enclosure to give me a GPSDO for the workbench. I also happen to have an uncalibrated 5MHz TEMEX LPRS-01 Rb source so I thought it would be

So far the initial tests on the QMX seem to be working fine. Just transmitted into a dummy load on all bands and everything seems fine. Will test more when I get it home later this evening, I was a li

Just curious if anyone who ordered a QMX online has had it shipped? My order shows complete on May 20th but not shipped yet. I am NOT complaining at all, just curious! 73, Bill NZ0T

I just finished my QDX from a kit and I plan to order an assembled QMX (I'm quite old with old eyes and found it was not a very easy task compared to what I could do 50 or 60 years ago with vacuum tub

Sorry but I want to ask the dumb question - is 12 volts the actual ceiling for QMX power supply or is it rather the old "12 volts but it's really 13.8 - 14.0 volts" thing? It's easy enough to reduce m

Hi, finally got a chance to test my HighBand QDX on TX today and started very positive, 20m worked perfectly, have built it for 12v but started carefully with 9 volts so as not to destroy anything :-)

Yes, another QDX smoked thread. Sorry about that! I've done some list searching and reviewed https://qrp-labs.com/qdx/qdxtrouble.html , but I hope to get some advice directly. I have a new factory-bui

I've built two QRP Labs 50 W PAs for 40 and 20 and they work perfectly--just as advertised. I purchased an additional one, thinking 30 meters. But with 10 meters wide open I'm wondering if it's feasib

Any idea why I get a key down sound with the dummy load but not when connected to an antenna? I then just get a buzzing sound.
