[Elecraft] K3 Toroids: Why some have uneven turns spacing (It's intentional!)

[Don Wilhelm]

Don,

I have built several K2s, and I know for a fact that the toroids do not 
change due to vibrations due to portable/mobile operation.  I expect the 
K3 to be similar.  At least one of the K2s that I have built has seen 
service in mobile operation in an 18 wheeler for several years, and I 
don't believe you will find a more vibration prone mobile situation than 
that.
