Maybe read the description carefully and ensure you understand what it says next time. Not that I think Hans' descriptions are misleading or designed to confuse. You just need to make sure you know

why are you distracted? 5w or 3w or only 1w... qrp is qrp... if you actually have 3.3w or in maximum 5w .... where is the difference and problem? keep calm and just enjoy your qrp- rig... otherwise

No, not really. I expected 5 watts EVERY band and have fiddled and diddled with windings and spacing and chanting in strange languages to get what you got which was not that much different than anyone

Oh, no. 3.3 W compared to 5 W means only 0.3 s steps lower. 73 Ludwig

I guess I should have had 3 watt expectations when I ordered. C'est la vie.

oooh, sorry, I don't want to glue. Please read clue.

Rico, All good suggestions for you in these replies. Don't look at this as an expensive mistake; it is a great learning opportunity to learn troubleshooting. Another approach is to get in touch with

Those look pretty good. Remember this is a QRP rig. The slightly lower output from what you expected will only make a difference in your mind, and will likely help preserve your finals. -- 73, Dan -

List of features: 3-5W output at 12V supply (can be built for 3-5W at 9V supply) Did I see any figure less than 3 Watts? I'd say you got what is says on the box. In any case there is less

My new assembled QMX+ showed up on my doorstep yesterday and I was very excited!? Everything checks out fine, but I find that I am disappointed in the reported power output levels: 160m 5.7w, 80m

works as expected... thanks Hans and team for the brilliant work.... vy 73 de Udo DF4BJ

Thanks, Stan, Using the refrigerator, I have confirmed that it is heat-dependent.? At 40 degrees, it took ~10 minutes to settle down. At 70 degrees, about 20 seconds. I wonder if there is a batch

Tnx Todd, I’ve checked the soldering after I fitted the coils very carefully because I knew those are delicate. Interesting is the fact that the sound coming out of the little guy doesn’t change
