The Elecraft designers have stated in past discussions that Coil Dope is not
needed if you wind your toroids tight. Remember, that the dielectric
constant of Coil Dope can change your tuning of the coil. It would be
alright to use a few drops on ends of winding as an aid, but a lot could be
a
Thanks to all who responded. I had no plans of deviating from the number of
turns that Elecraft directs. I will follow their instructions as to the best
of my ability.
I have learned a few things:
1) Adjusting the spacing of the winding on the toroids does not change the
inductance, just the d

Darrell,
Caution, The toroids should be wound as instructed - you may measure them,
but please do not try to make the inductance equal that indicated in the
manual/schematic because those inductance values are either what was
measured on someone else's inductance meter, or they are approximate va
As I build my second K2, I want to try to measure the inductance of the
toroids with my MFJ-259. The MFJ manual has instructions on how to do this.
Essentially one builds a series LC circuit and measures the resonant
frequency and then calculates the inductance.
Has anyone tried this and have a
