William,
I count 20 turns on both of the toroid pictures.? The difference is on the 14th turn.? I count 15 turns to what should be the 14th turn and then only 2 turns between 17 and 20 on the second picture.
L12 will not impact the QDX output.? For 10 meters on a high band QDX, that is L4 and L10.? Have you tried squeezing or expanding those toroid windings?
