I just finished my V1 QDX. I'm impressed at how well it does with ~4.5 watts out on 20m. I only have a dipole in the back yard (up about 10m) and I've been working numerous European stations from New

I just ran into the same situation, as in: "What? I just checked those windings and they weren't shorted. After adding T2 to the board, now they are! What?&!$%^&^!$%" Calmer now.

Looks very nice! Everything in one box. Which switching regulator did you use? I'm about 2/3 of the way through building mine and was considering using this one: https://power.murata.com/data/power/ok
