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

Use you ohmmeter to confirm continuity from one end to the other.
The biggest mistake most builders make tinning the toroid leads is that they
fail to tin
Lee,
After you've installed a toroid, check the resistance across the toroid leads
(all pairs if it's a transformer) at the solder pads. If it's zero, you can
be assured you stripped the leads properly and got a good solder joint on the
board. Since I started doing that, I've never had a bad tor

Lee,
Not to worry, the enamel itself will not adhere to the solder at all, so if
you have the leads with a nice shiny tinned surface, you can know that they
have been stripped as well.
As for zapping

Hi,
This devil has many appearances and uses different names depending on the
person in doubt. Several of the names are: Icom, Yeasu Kenwood, etc.
It isn't that difficult.
Put the part of the wire to be stripped flat on the surface of the edge of a
table. Take a real sharp knife and scratch with
You can see the enamel burn off, and the solder tin the copper.
Just make sure the iron is hot enough, and you take your time.
