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

Daniel,
The inductance of the RF Choke toroids measured at DC or low frequencies
may not agree with the published inductane which is measured at a higher
frequency. Those RF Chokes are not critical, they just need to block
the RF flow and the bypass capacitor takes care of the rest.
The
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.

Interesting that one never knows just how the quoted inductance is
determined.
Do you have any idea just how the Elecraft quoted inductances are
determined?
If measured, what frequency and test jig.
If based upon calculations, how much as built variation will there be.
Have had the
Brian,
The K2 toroids are specified in the manual for a given number of turns
on the proper core rather than their absolute inductance. The only
reference to the inductance is on the schematic and in some instances on
the parts list. What I can say for certain is that whatever the
dust in a RF lab.
