    Itsu:
   Ok, thanks for the information on the coils.  I had mine wound wrong, and have taken it all apart now, and am rewinding it, hopefully the correct way.
It may not make any difference, but who knows. The grenade had raised up my voltage much higher than what just the yoke will do by itself.  But probably at the expense of the amperage, as I could not light even a single 100 watt bulb the way it was.
  BTW: What kind of bulb brightness are you seeing now?

Hi Void,
If the inductance is too high, the pulses are attenuated and flattened, as the leading edges are slowed by a restricetd current rate of rise. Like Itsu, I have linked out my choke.

I see. Thanks!
All the best...

if you have a small capacitance in front of it; it will limit the current, and upset the resonant frequency... adding a larger cap in front of the coil should cover larger chokes ... allowing it to be in a DC mode rather than back oscillating to its supply...

Hi d3x0r. Ok, thanks. I will try some different cap values if I have simiar issues.
All the best...

Here is a shot of my Ruslan replication almost complete build. The scope shot is with the probe just laying on the antenna, which is why the trace is fuzzy. The Kacher was adjusted as close as possible to 1.736MHz with antenna and ferrite choke connected. The length of Kacher secondary coil is 7.5cm. The Kacher primary coil is tapped at about 2.5 turns of the 3 turns to increase secondary voltage which is about 2KV. Current draw is 1.6A.

I made a new Grenade coil according to the now known specifications:

2.5mm² stranded copper wire OD = 3mm, total length is 38.5m with 2x 0.5m connection leads (coil length 37.5m).
Layer 1 and 2 are  19cm long and are resp. 56 and 55 turns CCW
Layer 3 and 4 are 9.5cm long and are resp. 26 and 25 turns CW
Layer 5 and 6 are 4.5cm long and are both 12 turns CW

Tube OD is 5cm

Inductance measured is 168uH @ 1KHz and 166uH @ 100KHz

Main (and almost only) resonance frequency peak is at 1.290 MHz, see screenshot of the frequency scan (1KHz -> 10MHz)

Regards Itsu

My Grenade is resonating at about 1.15MHz (with bifilar coil wound over), so quite close to Itsu's. Is this frequency supposed to match to the Kacha frequency because to get down to yours and my grenade frequency would require a much longer Kacher secondary coil length than Ruslan is showing in his videos, or are we supposed to tune the Kacher to our 'earth' frequency (1.736MHz in Ruslan's case)?
