Skip,
No tuning is ever required for transformation! Niether is resonance!
Transformation is just the natural magnetic induction between two coils.
Resonant rise, in a resonator, never relies on tranformation but instead
on coupled, resonant, magnetic energy. These are two different animals.
The Oudin coil systems can never couple very tight on a normal small
diameter (under 8 feet diameter) coil. 100% coupling is possible only in
theory and never in fact. At RF frequencies and with air cores,
only about K=.7 or so is even theoretically possible!! With high voltage
concerns insulation, etc, in smaller coils, it is practically impossible
to achieve K=.5!!! Just because a primary and secondary are on the same
form, doesn't mean they are necessarily tighly coupled! With air cores,
they are almost never tightly coupled.
The tighest air core coupling would occur if the primary was wound
directly on top of, and directly in contact with the secondary winding!
This would still not even approach 100% coupling.
