Has anyone checked their toroid inductors after winding them with a DMM 
(inductance) to see if they agree with the values shown in the schematic or 
apendix A?  I was checking the  values to see if I didn"t pick the wrong 
toroid out of the little envelope. Well, RFC14 and RFC16 measured value 
didn't agree with the K2 Appendix A, they were about three times higher.  So 
I looked in the ARRL handbook 2-35 (1994) and used the equation to calculate 
the amount of turns, it ageed with the measured value, not what was on the 
schmatic .... did the calculations on the T5 VFO transformer, the 
calculations, measured values all agree....I really don't understand that 
much about toroids but would like to learn. Could anyone explain what  going 
on?  I have reading this reflector for a couple of months, and been impressed 
with how much You fellas know about electronics.

Thanks a lot,
