Just scanning thru the past several days worth of qrp-l digests. I didn't
see the following solutions to toroid half turns mentioned, so I'll enter
them here just for the record.
Since a turn on a toroid is whenever the wire passes thru the center of the
toroid, it is impossible to have a non-integer number of turns -- UNLESS WE
CHEAT!
The first cheat for this involves the fourth dimension and is too involved
to describe here, and therefore I will only mention it in passing in hopes
that everyone will think I'm smarter than I really am.
The second cheat has to do with drilling a hole thru the core of the toroid
so that the last turn will be a turn around half of the magnetic flux,
thereby having the effect of a half turn.
Difficulty in drilling a clean hole, inefficiency due to the added hole, and
negligible returns make the second cheat more worthless than the paper it
was written on. (Please, don't anyone print this!)
If for some reason anyone feels like they really gotta do this, have fun.
Me, I'll just wind the turns tighter.
