Hi Hans, No smoke (!), all calibration adjustments behaved exactly as documented, 4W out at 12V. It was a pleasure to build, and I can see some fun ahead! I cannot tell you how impressed I am. Thank y

Hi John Whatever smokes, it won't be that regulator :-D And remember, all Rev 2 boards have been through my super-duper test jig and passed its 21 tests. All 1,000 boards. Yes the test jig really did

Hi Hans, that was quick! Thanks for getting back, saves me a fiddly job. Others reaching the same point may see this thread and know they can skip the mod. I've enjoyed the build, now girding my loins

Hi John There is no need for the capacitor in Rev 2. No additional 10uF capacitor in Rev 2 (with the 78M05 regulator). I have not yet been able to update the manual. The only changes to the Rev 2 PCB

For my first QCX I didn't have to change any windings, but for my QCX mini 20m, I had to add 3 turns to T1. Its working great, though.

Good Eye, Mike. I did the 38T as manual suggests, and it seems to be working fine. But I would be interested in what others say about that, and if it makes a difference. I have already wound mine so I

For 40m and above, if you have small value capacitors (preferably NP0) on hand, you can also try them in the c8 slot if C1 doesn't have sufficient capacitance...

Remember it is not the number of loops it is the number of times the winding passes through the core.

Mike, You are not the first to point out the discrepancy of the picture to the manual. The reasoning that has been given is that it is easier to remove turns than to add them. I would suggest that you

I'm trying to understand the Secondary #3 winding of T1. I counted the windings on page 23, picture #15, in the QCX+ assembly instructions (Rev 1.04). I see 37 loops instead of 38 loops as the manual
