so i've been putting off building a QRP rig for probably two years now, always telling myself i'd get around to it when i had more time or whatever. finally bit the bullet last month and ordered one of those QCX mini kits from QRP Labs and man, what an experience.

the build itself took me a couple evenings spread over a week, nothing crazy difficult but there were definitely a few moments where i had to slow down and just stare at the schematic for a while before things clicked. i'm not the most experienced builder — my previous kit was just a simple audio filter thing — so the QCX was a step up for sure.

anyway got it working, aligned it okay i think, and took it out to a local park last weekend with my end-fed and a little LiFePO4 battery pack i've been using for POTA stuff. worked three stations in about an hour on 20m with 5 watts. one was in Florida which is pretty far from my QTH in the midwest. im still kind of amazed that 5 watts gets out at all honestly.

the efficiency thing is what really got me thinking. like i've been running 100 watts on my main rig forever and yeah it's convenient but there's something different about working a contact knowing you're running on basically nothing. anyone else feel like QRP kind of changes how you think about operating? also curious if anyone has tips for getting more out of low power — antenna stuff, best times of day, whatever you've found helps

yeah the QCX mini is a great first kit, good choice. i built one a while back and honestly it performed better than i expected for what it cost. the alignment can be a little finicky so hopefully you got a decent result on that front.

on your question about getting more out of QRP — antenna is everything, like even more so than with higher power. a really good dipole or EFHW up reasonably high is going to do way more for you than any operating trick. that said, conditions matter a lot and honestly i've found that early morning on 40m or 20m during decent solar flux is where most of my qrp contacts happen. chasing DX with 5w is doable but you kind of have to pick your moments, dont try to bust a big pileup obviously. and CW if you havent gone there yet — huge difference in what you can work compared to SSB at that power level

this is really cool to read, ive been thinking about getting into QRP too but wasnt sure if the QCX or something else would be better for a start. did you find the instructions pretty clear or did you have to look stuff up a lot? im decent at soldering but not super experienced reading schematics yet so kinda nervous about jumping into a kit build
