[HBQRP] Cool find - Toroid chart..

[Piatt, Darwin]

OK, this is a great chart.  The URL will take you to the 'start' or
Toroid Home page.
Just click on the toroid type on the left and it will display a chart
that tells you  how many turns you will need to make a certain value in
uH and will tell you how much wire to cut (including an inch left over
on the ends for soldering).
I like it..
