[Elecraft] binocular question on W1

[Ron D'Eau Claire]

There's two separate windings on that binocular core, John. Each winding
goes through only ONE hole in the core and around the end of the core next
to the hole. So you count a always: each pass through the hole is one turn. 

See Figure 2 on page 6 of the manual where the text says, "...The wire
passes through the hole in the core exactly 10 times (and passes down the
side of the core 9 times), so turn 1 is when you first slip the wire through
the hole, before you wrap it around the outside."

Subject: [Elecraft] binocular question on W1


Hi,
Just picked up my first three Elecraft kits, the W1, W1SERKT, and the 
DL1. I finished the DL1 this past weekend and just completed the W1SERKT 
a few minutes ago after doing much of the work on the W1. I stopped 
working on the W1 when I got to winding the magnet wire on the binocular 
because I have a question.

For those of you who have built the W1, please offer some clarification 
for me.

Winding the binocular is just like winding a toroid, no? For example, 
when I make the first "loop" through one of the binocular holes I have 
actually put the wire through twice which should count as two of my ten 
times through the hole.

Just want to make sure I'm counting correctly as I don't want to built 
the kit twice.

Thanks!

P.S. Can't wait until the custom enclosure is finished up by W8FGU. 
Thanks also to AG4NN for passing along the PDF of his enclosure as well. 
Quite impressive.
