  Yes, closing the inductor coil changes the grenades output coil's frequency, big time.  But, then we're not actually reading the "self resonant frequency" of the grenade coil in that case, now are we? If the Kacher, inductor, and grenade output coil are all in place, anything can change the frequency, even your hand being too close by.  Maybe that's why Akula shows it working isolated from the other coils, and with just a ground on the coil's free end, and he was able to obtains a self resonant frequency reading of the coil, in that way.
Even though some guys couldn't get it to work that way at all.

Edit:
  TK: Ok, thanks again for confirming the reading. For now, the CalcTool is the easiest for me to use. Now that I see where I went wrong when using it before. However, I'll get into taking more of an exact reading soon, as I can see the point you've been making, for myself now. 
 
  So, 1.81Mhz is where there's some action on my set up. Connecting the SG direct to the induction coil gives a much higher amplitude, compared to the two wire test coil's 1.8Mhz reading. While also showing a peak frequency just under my SG's 2Mhz top end. Possibly another related harmonic similar to or the same as the 1.81Mhz frequency of my grenade coil self resonant frequency, by itself.

Can you show very simple schematic of your setup?

I'm using the components and flow shown below.  The DC-DC converter (not shown) is a basic low-power push-pull similar to Ruslan's.  The idea is just to bump up the voltage enough to where the Tesla coil is effective with the lower turn count on the secondary.

Hi Dog,
Thank you for the picture   I C U have some big amplifier. My is only small

Hi Jeg,

But this grenade coil is very sensitive to stray capacitance as the position i put the 2 winding FG loop shows already different resonance peaks.

You are very right. But..
If tuning was the only problem we could have managed until now to solve Ruslan's case. The basic problem is the false schematics and the misleading on principal theory. 

By the way. How do you make this fantastic FFT measurement? Do you know if Rigol has an internal sweeping generator or do i have to use an external source for sweeping?

ps. Nice work DogOne. Very good looking boards!

Jeg,

these are no FFT measurements (at least i do not use my scopes FFT function).
I use my Rigol FG (DG4102) to setup a frequency sweep (here 100KHz -> 10MHz) and external sync the scope to this signal.
I don't know if your Rigol scope has an internal sweeping function, i thought it does have a FG build in.
