[Elecraft] T1 build...

[Don Wilhelm]

  Ross,

You are looking too hard!  Most of the Elecraft tuners use the same 
technique - the selected relay is activated and the return path flows 
through all the rest of the other relay coils - there is not enough 
current through any one coil to activate them, and it works quite well - 
one more piece of "magic" that can be done using PICs.
