From Hans's UTube tutorial on aligning the LPF I might make mention to that part of the tutorial where he specifically tells the viewer to add/remove turns to the toroid according to whether one gets a power increase by compressing or decompressing the turns on the toroid!? If one sees an increase in power when one compresses the turns, then more inductance is needed hence add 2 turns because compressing turns adds inductance. And decompressing turns says you need to remove turns to get? the power up to snuff.
