Franz,

So, you feel there is no difference between progressively shorting a tank coil compared to free tapping it without shorts?
The free tapping is what causes the unwanted autotransformer action, but I always thought it was a cleaner and less loss way of doing it?
Isn't there SOME circulating currents still in the shorted turns and jumper?
