Re: [TCML] Small coil results

[Mddeming@xxxxxxx]

Hi Greg,
 
I agree that there can be multiple firings per cycle if the cap is small  
enough, but the cap charging to firing potential 42 breaks EVERY half  cycle 
seems really strange.

It is a  mistake to assume the break rate of static
spark gap is yoked to the AC  mains frequency. If the
charging current is stiff enough and the tank cap  is
small enough, a simple static gap can achieve multiple
firings during  each AC peak.  In other words, the gap
fires in "burst mode" near the  peak of each
half-cycle.  As there are 120 peaks per second  at
60Hz, the break rate could get "up there" pretty
quickly even with  only a few firings per peak. 
Quenching with such a system may be poor  or
non-existant, but the original post never claimed good
efficiency for  the small coil.

Even so, 5000bps seems pretty amazing--more like  a
continuous arc than any discernable "break", or
switching  action.  Unfortunately, I don't know enough
about air spark gaps to  support or refute the claim of
5000bps from a 60Hz mains input.  An  (o'scope) picture
would be worth 1000 speculative  words!
