Hello, I ordered a fully assembled QMX in April, and got it about two weeks ago. It died while i was listening to it. I maybe have listened to it a half hour total or less. i was switching bands and got a real sharp noise from my speaker, and then the screen went blank. not sure what the problem is, but i have only listened with it, and haven't even transmitted yet as a dont do cw yet, and i was building a mic for ssb. I was hoping to try digital modes on sunday, but i was just about to tune in to see if i could hear the 10m FT8 band as its a nice and sunny day, and i haven't been able to even hear ft8 on 10m as of yet. but its been pretty stormy here when i have been able to look at it during the week. I have not open it up as i am not sure if Hans will want me to return it as is since it is so new, or if im stuck and have to repair myself. I really dont think this should have died after only about 20 minutes of just listening to it. i know things happen, but i would have just bought the kit. It did turn itself off a couple times randomly before this. TBH i thought this was just my battery turning off since the draw is so low on receive. but maybe there was a problem in the first place? I did measure a resistance a couple places, and battery terminal is fine, but the antenna to ground is less than a half ohm? also not sure how to contact hans for what to do, but i replied to the email sent and tried the "help ticket" but not sure i should message him here? thanks, Ted

Sounds like the U.S. penny might be going away. I was inspired by the touch feature of DL1CR's touch feature on his QMX Carrot. This is pretty easy to print without supports, but you do need a couple of pennies! https://www.thingiverse.com/thing:7049323

When Elecraft introduced the KH1 a year ago, I was immediately enthusiastic about the concept. A small and lightweight shortwave radio with an integrated telescopic antenna. This means that, weighing less than 400g, it can be used in any suitable location on shortwave. So I wanted to build something myself. I immediately began my own experiments with telescopic antennas for 7-30 MHz. This confirmed that a counterweight is absolutely necessary. This wire, which is a quarter of the wavelength long, contributes significantly to the radiated energy. So the idea arose to forgo the telescopic antenna and experiment with end-fed wires twice the length. Of course, it makes sense to stretch the wire as high as possible. But I also got respectable reports with EFHW lying on the ground or in bushes. In this place the antenna may detunes itself, so a tuner is necessary, as well as the standard 1:64 transformer (Unun). The tried-and-tested resonance circuit (Fuchs Kreis) performs both tasks. Once the antenna issue was resolved, QRP Labs brought out the QMX. The ideal TRX for my projects, and now even capable of SSB. Now all that was missing was a suitable housing with an integrated battery and a speaker with an amplifier. Then a paddle for CW as a contactless touch key directly on the device. And the QMX Carrot was finished. But it wasn’t that simple, because everything had to be as small and light as possible. It now weighs 340g and measures 15x8.5x3.0 cm. I’m happy with that. 73 Chris https://youtu.be/0kksiWVOtnQ

Does anyone use Solder pots for tinning and removing the enamel from the toroid leads? Any hints and tips? I see a cheap one on Amazon for about $20. Any suggestions if I should buy special solder for this, or use my normal Kester 63/37 solder in it?
