[Elecraft] [K2] Inductivity of Toroids

[Fred Smith]

Hi Daniel

I must admit I took the cowards way out and ordered the pre-wound ones. But I'm interested in seeing the responses you get from others that may have measured them.

Happy New Year

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...
