Re: [TCML] Primary selfC



Bart,

I am not sure how much the secondary will effect the primary, its why I used loose coupling to stop the interaction as much...

I am not sure this is going to be easy to measure, as I have to build the primary and then its pretty much fixed, so its not easy to alter it to test with and without the secondary coil :-(

Chris,

Thinking about your high Q secondary, it's one thing to measure the primary outdoors away from objects to determine C. However, when in position with the secondary, it is wise to measure it with everything else in place as C will change. I'm not sure how much, but you need to measure it in it's location. With such a low tank, not only is the primary C becoming significant, but also the external C.

Regards,
Bart
