Building the KSB2 SSB adapter

[Mike & Paula Herr]

While building the KSB2 SSB adapter I noticed something strange on page
11. The drawing for T1 and T2 shows winding 3/4 wound in one direction
and 1/2 wound in the opposite sense. My experience is that typically
both winding are in the same rotation. Is the drawing correct or should
both windings be in the same direction?
Thanks

Mike,

It really does not matter since these are just used as transformers (as
opposed to transmission line transformers).  In fact, I believe the toroids
that The Toroid Guy winds have both windings in the same direction just
because it is a little neater that way.

Mike,

I believe the drawing is correct. It shows two windings that are wound
with different colors of wire. Unless there's a misprint, you should
see the 3-4 winding in a lighter color than the 1-2 winding.

While it may appear that there's a reversal, you'll find that after
winding it, yours looks very similar. Neither winding changes
direction, and both are wound in the same "sense."

Let me know if it's still confusing after you perform all of the steps
on page 11. I could clarify something in the next revision if
necessary.
