My assembled QMX is in the 200+ shipping position. There's been enough chatter on the forum to dissuade me from building it. It was an acknowledgement of aging eyes that convinced me to just get one assembled. Nice radio series. If a new ham was restricted by funds I'd recommend this series of radios. They'll get you on the air very easily and because it's CW, even qrp signals do well.
Very nice thanks. Built a few QCX kits and found they compare very favourably to commercial rigs on CW RX. Have a QMX kit on order and looking forward to building it.
Nice to meet friends here! Thanks for the video Willy, I‘ve baught the qmx kit from Hans in Friedrichshafen. At first I finished the build of my QDX baught last year, it works great! The QMX will follow soon, looking forward to the features that Hans will pack into the software in future updates. Vy 73!
Hi Wolfgang, so soon we will have an 2xQMX QSO :-). Although less components than e.g. with the QCXmini to mount, every mm counts, so take your time (and a microscope HI) for the build. Currently SP/OE3WYC 73!
The QMX is a fun radio to have. I've had some great success with mine at POTA. Really looking forward to getting AGC and possibly SSB. If Hans can properly implement SSB then it will probably make for one of the cheapest SOTA rigs you can buy.
Had a bit of a problem with my QMX but should be on the air this weekend, excited. It was not an easy build for these eighty one year old eyes but a lot of fun. I would like to try it again knowing all the things I learned on the first build. I am having fun with qrp with my QCX. QRP Labs puts out some really nice products.
Yes, I think there are less components to install than with a QCXmini, but even with my 56yrs I needed a good magnifying glass! Hope all works out fine with your QMX!
I've got a QCX-mini, which is a delight. I'm waiting for SSB to get this QMX. Given as-yet-unused power of the chip, this QRP-Labs transceiver is only going to get better and better over time. My only frustration is that I can't operate the digital modes from my iPhone.
I have THREE QCX Mini's already and a QMX on the way, What should I tell my wife when she notices another on my easy chair table and she rolls her eyes back? Do I say I forgot to keep the light on again and they multiplied. I don't think she will believe me a second time.
Hi Willy. Great video.. The excitement you showed at the end was the same as mine when my 20 Meter QCX came to life and I had my first QSO. When I started in QRP many years ago with a direct conversion RX and manually switched TX in my Lake DTR 7, I could only dream of the performance and functionality of the QRP Labs products we enjoy today.. I have several QRP Rigs in addition to the QCX Mini including Elecraft K1. KX1 & KX2 so do I need another QRP Rig? 🤔 Hell yeah! For me as I’m sure it is for you? The pleasure is in the build and then making contacts on something we built. 72 my friend Hope to work you soon? G0HFL 👍
Thanks for posting this video! I was just wondering if you built this for 12 or 9 volts? If 12 volts what are you using? From what I'm reading there's not alot info regarding exceeding the 12 volts, ex 13.8 volts. Perhaps a Buck converter to solve this issue?
Will power the QMX with 3 LiPo cells (like I do with the QCXs). So, if they are fully charged, we will be at around 12.6V. I think this should be no problem for a "12V" QMX. Here for the first QSO it was on a lab power supply set to 12V, but I also checked it at 14V (for a short while, even in TX) , and it was not destroyed immediately ;-)
@@polarbear5464 Hi, personally I don't think there is any danger, provided you have the SWR protection in place. I'm using even higher voltages, if the battery is fully charged... Of course no guarantees 😉. 73 Willy, oe3wyc+oe1wyc
no, no, on the contrary, it is quiet. I had problems with the recording. But since it was the very first QSO with the just assembled kit, I still posted it... 73 Willy
For digimodes yes. In CW I couldn't see any, but I'm sure that will come with one of the next FW releases. There will also be some sort of SWR (maybe also power) indication...

Well, one can't compare this tuning knob with that on the main transceiver at home. It is indented. But that is a good thing for a portable rig. You can step through the entire CW section of a band very quickly in 500Hz or 1kHz increments. Most stations today anyway are working on integer kHz (or multiples of 500Hz) frequencies, so you won't miss anything. It's very practical. I like it. Also on other portable rigs like the G90, the HB1B and so on
There are some firmware bugs. I can' t lower audio volume to zero and sidetone volume settings not working as it should. Had a lot of fun on all bands so far and 20m sensitivety is ok now. I compared a weak stn with my TS480SAT. Equal reception. I'm a CW guy. Don't care for digi modes or SSB. BTW on my YT channel is a short video as well
The firmware will improve over time... Thinking of SWR meter etc. where the hardware is already there ;-). Have same "issues" as you mentioned. And hoping for a "broader", less tiring filter. Will watch your video now :)

Sounds good!
Is using 12.2V dangerous for the 12v version? Just wanted to make sure. Thanks!

I'm waiting for the mid-band version, then I will order one. Don't need 80/60 nor 12/10m.
I ordred this version 20/17/15/12/11/10m. I wanted 17,15 and 10 meters , Hans now has AGC with the updated firmware.
Is it this radio so noisy ? I'm waiting for my one :) but this noise sounds annoying.
no, no, on the contrary, it is quiet. I had problems with the recording. But since it was the very first QSO with the just assembled kit, I still posted it... 73 Willy
Does the QMX give any visual indication of transmission?
For digimodes yes. In CW I couldn't see any, but I'm sure that will come with one of the next FW releases. There will also be some sort of SWR (maybe also power) indication...
Together with the SWR functions we now got a power indication with the new firmware version. This is sufficient, I think... :-)
I will buy one when it does ssb
Building the QCX plus 160m version currently. Have a QDX too, Awesome products! 73 de VK2AOE

No morse reader in QMX??
Yes, reader is there, already now. I activate it later during this first QSO, but it was probably not configured optimally...
Does this radio have AGC?
Yes, AGC came with one of the last firmware revisions. At the time this video was shot, AGC was not implemented yet... 73 Willy
LZ5DD ? or LZ5BB ?
Hi tnx for posting this video.
I have finished one here last week
