  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.

73,
