[Elecraft] Neurotic about Toroids

[Leigh L Klotz, Jr.]

Lee,

If you don't choose to buy Mychael's pre-wound toroids (which I did for 
the K2 RF board) you might want also to try these two hints:

1. Make sure to wind the toroid the right way, with the top wire being 
on the correct left/right side of the bottom wire.  Elecraft's manuals 
always have pictures to go by.  If you get it backwards, it will be a 
mirror image of what it is supposed to be, and it won't fit in the hole 
right, and no amount of turning the toroid around again will make the 
holes line up, hi hi.

2. Everybody tells you to count the times the wire goes through the 
hole, but nobody tells you how to verify it afterwards!  Once you're 
done, count the number of turns on the inside rim of the toroid and 
ignore the outside rim.
