We're almost finished. All we need to do now is install a few remaining parts that have to be handmade - for that
41. Winding L1 and L3 toroid RF coils (two identical units ): Locate 2 of the
donut shaped yellow toroid cores provided in the kit. Cut 12" of the enameled magnet wire and, following the drawing, thread the wire through the core 19 times - not 18, not 20; it MUST be 19 times through the core, pulling each turn gently tight. Winding too tightly runs the risk of scraping off the enamel insulation and shorting the wire. Tin each end with solder by holding your soldering iron and solder the wire ends until the insulation melts away and the copper wire underneath coats nicely with solder. Tin all the way up to the toroid core body.
19 turns through center of core
IMPORTANT: Loop the first w inding through the front of the core as show n.
42. Winding L2: Locate the remaining yellow toroid core and cut 15" of the enameled magnet wire. Wind 22 turns through the core using the same procedure as above. Tin the wire ends as before. Mark this part with a piece of tape, a dab of paint or a magic marker. We don't want to confuse it with the other two toroid coils wound just before!
22 turns through center of core
IMPORTANT:
Loop the first winding around the front of the core as shown.
43. Winding T2: Locate the smaller of the two
