Re: Re: BPS?

["Garth van Sittert" <garth-at-mediasupplies.co.za> (by way of Terry Fritz <twftesla-at-uswest-dot-net>)]

If the spark gap fires at only ~120 bps then how does the primary coil and
cap resonate with no current path available (ie no ionised air in spark
gap).  Does the primary tank resonate only while the spark created by the
NST is there to conduct.
