Can you be more specigic on the method and the measurement coil?
I m not familiar with how Akulas did it

So for good understanding, attached the method for connecting and probing.

So method 1: adjusting groundwire coil at 2Mhz and monitor Vpp at connection #2?

Btw, groud connections SG and Oscilloscoop are separate connected together and to the grid grounding.

That looks like a good starting point.  If you can use your two probes
in differential mode (math minus function) without attaching the ground,
that would be best.

We want to see if the amplitude changes when the ground is connected
at the resonant point and if so, by how much.

Then we want to see if the resonant point shifts frequency when the
ground is connected and if so, by how much.

Yes, this could be a problem I hadn't thought of.  We need to keep
the ground clips from being connected to the coil if at all possible.
I'm thinking if you only connect the signal generator ground clip to
the inductor, hopefully this won't distort things too badly.

I also sent an email to this guy asking about how we might be able
to simulate ground wire impedance determination.  I probably won't
get an answer right away or at all, but figured since this guy knows
his way around LTspice, maybe he would be interested enough to
lend a hand.

Ok, i made small vid in first attempt to see what happens.
Connected SG to inductor...
Math function on and sweeping frequency.

My first results w/o math functionality is based on Vpp , see attached overview.

I thought you said you were a keen amature radio guy only as far as i know you only need an earth for 1/4 wave.

   Yes, he keeps throwing odd balls at me, to try my patients. Asylum crew... 
Head nurse Miss Ratchet said he was out on good behavior, though.

  We do know what has been tried, and did not work. But, no new developments lately. I am always testing the waters, for the missing link.   Some help from someone that has shown success at this project, would help.   Makes we wonder if Geofusion hit it off, and ain't saying...He's been MIA for a long while now. 

  Andrey245 is now working on this project, check his YouTube channel, if interested.

Dog-one,

I now hooked up the SG to the inductor coil, problem is in general to obtain any resonance frequency.
I only record the Vpp hen both signals are in phase.
Attached one oscope example.. ch3 is end grenade, ch2 is start point grenade

So see data attached, w and w/o groundline connected to grenade.
I hope this gives some more insight information.

Scope picture separate.
Also did a FFT sweep on 9, 4 and 0 groundline windings
See vid below.

Re; your video reference you posted on pulse width.
that wave form doesn't look in resonance as different parts of the conversion are at different amplitude.

Arn't we getting a bit confused here, it looks to me as if your trying to  pump 2mhz sine wave into your
coil, in that photo, and yet you have a video on you tube referring to pulse width and fly back.

The problem with BEMF is if unloaded it will rise in voltage to an infinite value until some thing breaks down, however if collected in some way it's load will diminish it, as it's a very narrow pulse, and how would one pulse at 2mhz produce any power significance in a low frequency audio freq,  half sqr wave if that's where the energy is suppose to come from.


Fun ainit, Sil

The vid about pulsing and bemf is done with bifilar coils.
Not with grenade

This is my configuration.
I added pp foil between layer 1 and 2 for mor capacitance in order to get the 2.0Mhz region.


I also made a version w/o the plastic sheet between layer 1 & 2. Turns out by making layer 6  resp. 10 to 4 it corresponds with the original grenade frequency..
