Another note of encouragement. If you take it slow, and like Hans' says triple check each connection, you can't go wrong. Like travel, half the fun is getting there. Good Luck! --Al WD4AH

Hi, My QDX is nearly finished, and I now realize that all powersupplies I own give out 13.6 volts. That's a whopping 1.6 volts more than advised. I did provide for extra cooling of the BS170s, and I

Besides, just following directions (when building a new kit) isn’t really teaching you anything. If it doesn’t work and with help from others on this connection you finally figure out what is

OK, here comes some truth: if I can do it, anyone can. Due to the rigors of my career path, I have carpal tunnel issues along with arthritis in both hands...let's just say that my soldering skills

Thanks for the tip,. Just ordered the FR301 I always wanted. They are expensive but absolutely great for desoldering. Which as I get older it seems I have to do more of….. grin. Also picked up their

Thumbs up! Gonna get me some of that. (I was pleasantly surprised when my KD1JV Tribander kit came with the slippery decals. ) JS6TMW

And do remember not to follow the instructions when installing the inductor in this tuner. That’s the key to success as it took me years to learn,

I previously tested this using the 10A setting on my multimeter as the uA/mA setting wasn't working.? I found that the low-current fuse was blown, replaced it, and retested using the lower current

For my experiment, I used Windows 10 Voice recorder connected to the motherboard sound card, and WJST-X connected to a USB sound card (that 'was' connected to my HobbyPCB RS-HFIQ). MB Mic to USB Spkr

Thanks for verifying it! --Al

Build it! You’ll have fun. And the satisfaction of doing it yourself. If it doesn’t work, there are folks on this list who will help you to get it right, no matter how limited your own

I have read the manual, the physical building process doesn't scare me, but the troubleshooting afterwards does. Luckily, a board member is going to build this one for me. Thanks ! Charlie

What voltage are you using on the ATU-100?

It’s a fun build. I would say it is medium difficult. There are no SMDs to solder. Only you can decide if you are ready but read the manual while you are waiting. -- Colin Kaminski - K6JTH

The more I read on this (and other forums), there seems to be a lot of pitfalls in building a QDX. I bought a v1 from another ham and it was awesome for about 4 months until it smoked all of the ICs

Finishing up my?"Manual Days" QRP Chinese Antenna Tuner and decided better artwork just had to happen! I watched way too many YouTube videos on ways to label front panels. I discovered there is a

OK. Is that still the case if well formed audio is sent into a qdx, or will it also have a clicks?

Hi Steve, The features are impressive. If I was faster at remembering how to get to presets, I could have three presets and continue to leave my resolution at 50hz. Right now I spin from 20 to 110 and
