I had a think about Richard's post last night and realized I might 
have misinterpreted the way he and you are wiring the resonators....

Correct me if I'm wrong but you actually connected the resonator 
bases together and then connected that connection to the top of the 
driver coil??  That is not the way to do it. My way is *guaranteed* to 
work. The correct connection for twin free resonators is to connect
one to one end of the driver tansformer secondary and the other to 
the other end. Currents at each end of the driver are in opposite 
phase and mirror each other. You can see from this that winding 
direction doesn't matter and that any magnetic coupling is 
undesirable. In the twins with one resonator driven, the passive 
resonator is in fact replacing the 1/4 wave ground image.
