Hi Guys,
I’ve built a high voltage capacitor array today, and have ended up with at least some streamers that break free of the torus on their own.

The video is only six seconds due to the noise it makes at night! It’s spark gap driven, and has a way to go, but getting there.

The capacitor bank value is still arbitrary at the moment, it doesn’t have good RF Earth, and the primary is not finely tuned either. S I anticipate a lot of improvement moving it from the rough setup to the nicely built finished thing.
There’s also a larger diameter torus on the way.

The capacitor array I started on today is 35kV, 2000pF as a unit.

They are 7kV 1000pF individual caps, so not bad.

Cheers, Brek.

Put a Morse keyer on that rig and they'll hear you on the moon.

Haha! It’s a problem that I’m licensed and should know better.
No plausible deniability!
The general idea is to get them right down low.
It’s not uncommon for a large one to sit around 140Hz so I hear.
Of course the spark gap would be messing up MW & HF within a certain radius.

Ok, a little progress with modulating the coil with the telephone ringer and DC solid state relay

Love the idea of being able to hear the landline ring miles away on the pocket radio.

Haha, It's only at MW band with the larger toroid attached.
That’s why additional turns are required for the primary.
You can see in the video the secondary is resonant at 700kHz with the larger toroid,
but all testing in the video is done with the smaller toroid, in which case I use less turns on the primary to match,
and it sits in the 160m amateur band. Still not good, but the boys at the club at least know about it.

They think it will make a hopeless radiator for any distance, but possibly make a mess on a number of harmonics locally.
That is why I want someone to listen. Most of the amateur HF bands are harmonically related:
160m,80m,40m,20m,10m.
