Hi friend , I was studyng the coil schemes and both coils  are mid-point or two superimposed coils and one is connected and the other is not . 20 + 20 turns .
Remember to do proper shielding and leave 5mm gap open .
Sorri for my bad English .
Greetings .

:)On page 112 you have a semicircle to wind up.
Or what you do not know is to make shield ?
