Re: Terry's DRSSTC - Experiment - A curious thing...

Hi All,

I quickly set up the plane wave antenna and got a current probe on the primary.

Here is the top voltage in some voltage units in yellow and the actual direct primary current in blue. The sparks are short at about 1.5 inches and rather "puffy". The BPS is 772.

Changing nothing else but the PBS rate to 800 gives a spark length licking out at about 7 inches with these waveforms:

So, nothing very dramatic is happening to the coil voltages and currents!! It almost seems like the longer streamers are relieving the secondary of a "little" load and allowing a bit higher voltage. But that is pretty small (or the longer streamers couple to the antenna better...). The waveforms do carry over a bit from the last, so "maybe" there is something to that... But the basic waveforms do not directly explain the dramatic difference in output sparks...

Don't know what it all means, but you know what I do ;-))  Testing continues...

Cheers,
