[Elecraft] Toroid Balun Cores

[Jim Wiley]

OK, now I am confused (a normal state of affairs around here)


If a "cracked" toroid core is useless,  then how do the "split bead" 
clamp-on cores manage to work?  Isn't the "split" equivalent to as great 
big lengthwise crack? 


I also seem to remember broken ring cores working again when glued 
together. 


After all, isn't a ferrite core itself manufactured from ferrite powder 
that has been "glued together" by a binding material?  Yes, the 
particles are pressed very close to one another,but they are still 
individual particles, are they not?
