Hi John,
          I have to thank you so much for the excellent experiments 
you are doing. This latest post really caught my eye and in 
particular, the last bit:

This all shows evidence that it takes a discharge to affect quenching 
- i.e. the system is coupled *during* secondary discharges. More 
interesting though is the shift of the quench when the discharge 
becomes heavy. This is the first evidence I've seen outside my own 
experiments that the lowered terminating impedance reflects back to 
the primary as a higher feed impedance. I am extremely interested in 
these results. I'll stick my neck out and hazard a guess that an even 
greater primary surge impedance at this k would improve that quench
(or a lower k for the same primary).

Please keep us posted.
