K6JTH was kind enough to send me a sample of his 3D design for a QCX-mini stand and I’m impressed. Good design combines the simple with the versatile and this is both. Hans might want to look into off

My 3rd build, 40m, 20m and now 17m. It went together perfectly. L3 wound with 12 turns instead of 13 turns to achieve 5 watts output at 12volts, 6.25 watts at 13.2 volts might be too high. Thanks for
