While we are discussing toroids, be careful not to put an extra turn on
the toroids. A straight wire through the center of the core is 1 turn,
a full wrap around the core is two turns. Toroids are different than
solenoidal inductors.

Dear K2-Experts,
I´m just assembling my K2, and it´s true: It really is addictive :)
After winding my first toroid inductors, I measured their inductivity
with an atlas LCR40 component analyser before I soldered them into the
RF board.
Though I closely adhered to the manual, the measured inductivities are
almost twice as high than the values stated in the manual (on the
parts list in appendix A).
It was good to read on the elecraft homepage, that the inductivities
are not too critical for the entire function of the transceiver. But
I´m still wondering if anyone else measured the inductivities of the
toroid inductors and made similar experiences...
