[Elecraft] Toroid headscratch

Hi Paul,

Yes, the inductance is a function of the square of the number of turns so an
extra turn can make quite a difference.  You should remove the toroids and
make sure they have the correct number of turns.

Hi
I've just completed the filter board toroids L9-L12 on the K-1 and soldered
them down, only to find that I've an extra turn on each !
Will the increased inductance be an issue for the low pass filter's
effectiveness ? Bands are 20 and 15
