Re: tesla secondaries/locomotive wire

Hi all,
       At the risk of being a pain, I want to add a note, and ask
a question....

I have a friend in Britain (with whom I'vve temporarily lost touch)
who is looking at EXACTLY that approach. He has sent me some notes
which I have yet to study. May have a post on this later.

In the one resonator (i.e. secondary alone)? I don't think you can.
What my friend is looking at is matching the velocity corrected wire-
length to the distributed L and C.

Could you elaborate on this for me please? (e.g. closer to what?)

Thanks,
