Now that looks cool. 
I like that one, do you have the building details documented somewhere?
That looks brilliant, well done. Do you have a build anywhere for it and perhaps the STL for the case? I would love to give this a try.
I still can’t get the @K6ARK mic I built to work with my QMX, the KX2 one works fine though. This looks like a great little all in one solution, perhaps to modify the mic wiring so you can make them for other radios too?
Pressure paddle is based on VK3IL paddle:
Here is my schematic:
For STL files and other details, send me email (adress is on qrz.com).

Great Stories and chat on this thread.
I copy some of the txt paragraphs into Just Learn Morse Code on my PC and sit back relax and read CW 35wpm checking out your stories.
Probably my down side for owning a QMX is I have 4 other QRP radios with very little use sadly.
Regards and thanks Ian vk5cz

I ordered my first QMX soon after its launch with the promise of ssb to come. Failure to notice a broken SMD device caused that one to die immediately but, undeterred, I ordered another. That one worked and had a few firmware updates - so where was the ssb capability? Evidently causing Hans some seriously hard work!
Lots of missing steps here but it got to the point where I was going to have to try an activation using CW. (Digital modes have no appeal at all for me.) Fortunately I, and any possible chasers, were spared this awful event by the release of the first ssb firmware. “for the Brave” so I resisted the temptation until release 3 which was installed and tested. On 24th March 2025 a garden operation got me an Itallian pota and G/LD-036, Melbreak. Wonderful 
So a couple of days later I visited Burton Hill, G/WB-020, an unpopular local hill (with only 139 activations 9 months later) and made 11 contacts ranging from Kinross to N Spain. 8 local hills (and 94 contacts) later the QMX was promoted to the radio of choice for our imminent trip to collect some more uniques in Scotland. It was used on every hill I was able to activate, with 115 contacts there on 40m and 20m. The score has now reached 707 QSOs.
So now I have 2 more QMX - still under test and of uncertain reliability. These are both hybrids - the hi-band version modified to include 40m. The first one died just after I did a club talk on building the kit and I could not find the fault so I ordered a replacement. Fault now corrected - ONE only of the 4 finals died and shorted the power line. Waiting now for a better microphone - slowest on-line purchase I have ever made, just coming up to three weeks! Costing more than a pack of 1000 ordinary electrets from China so it had better be good 
An amazing little gem. Many, many thanks to Hans - and to his cohort of on-line fault identifiers and helpers that enable incompetent kit builders (like me) to make progress.
