It can be easily verified with SG and scope. If you see Max amplitude on the output of grenade coil when you feed that signal directly to the Tesla coil, the setup is correct.

There lies the engineering difficulty.  You can't just SG the Tesla coil.  You have to build it to run at a particular frequency, so math becomes important so one can make a reasonable estimate of the needed frequency.  It takes me days to wind a proper Tesla coil to operate at a specific frequency.  I don't have that many days left to run a full sweep of frequencies hoping one of them just happens to be close enough to see the mixed frequencies appear on the grenade coil.

If I know exactly what frequency my grenade coil naturally resonates at, I should be able to use that information to calculate what frequency the Tesla coil needs to run at. 

True?

  Dog-One:  I don't know much about that yet, as that's what I'm trying to decipher.
  As I understand it, the Kacher secondary coil should resonate at the SAME frequency that the grenade's output coil SELF RESONATES at. But, not with the grenade's (168 turns coil) normal running frequency when it's all connect up to the yoke. However, the Kacher's output frequency at the antenna coil, should be the best resonant harmonic peak, of the grenade's self resonant frequency. 
  Both the Kacher, as well as the grenade coils need to be earth grounded, using a 37.5 meter ground line, also.
  Itsu may be able to give you more info on all that. As I'm just learning about it.

It is simple logic about what causes instant burn of coils and elements and how to utilize  in useful way what EE are trying to suppress.
Not just "knowing" Ruslan/akula/Dally/Kapanadze secret. Thinking outside of the box about destructive effects in history of electric power transmission and circuits will surely lead to some ideas for testing.

In many cases transformer / coil 'burn-outs' are caused by insulation / dialectric breakdown from electrical fault conditions and external environmental effects, such as lightning strikes. Lightning striking a modern sub-station can cause a rise in local earth potential, leading to high voltage induced currents in ground routed cables running close to substations. The destructive efects can be manifest miles away from the substation in the form of HV arcing across cable terminations and burn-outs in electronic apparatus. Also, cable damage can occur if communication cable sections are coil loaded and earthed at intervals. I was witness to this type of event whilst commissioning apparatus when a high potential transient at an estimated 4KV hit the comms IDC termination strips which resulted in a fire within the equipment cubicle. The lightning strike causing this event hit a substation a few miles away. Its reasonable to assume that not all the manifestations of environmental afffects on cable and electrical apparatus were understood in Tesla's time as well as they are today.

Lets not discard it all together. The insulation breakage occur not always in normal operating conditions as there power surges happen. Some spectacular arcing happen when there are wires being disconnected such as in https://www.youtube.com/watch?v=MAlyEMQxTN0 or some initial short path introduced as in https://www.youtube.com/watch?v=-yBTHrXEK4U and also the wire can be physically kicked by higher current on the power on moments. We all know about BEMF but when it happen to make plasma from air, the things are different as there are oscillations making high frequency spectrum in the plasma.
Also for the power surges themselves the lightning is not always cause and I am referring more to conditions N. Tesla was talking about. What is the source of power surge and how it happen is the key to reproducing it on intent for the energy harvesting purposes.

You can use this circuit, which has maybe three dollars worth of parts, to find the 1/4-wave resonant frequency of an open-ended aircore coil. You connect one end of the coil to the circuit's output, tune the potentiometer until _both_ LEDs are at maximum brightness, then use your scope or frequency counter to measure the frequency at that point.
The circuit covers a frequency range from under 1 Hz to about 1.6 MHz with a nice square-wave pulse of 50 percent duty cycle. It uses the built-in Voltage Controlled Oscillator in the CD4046 PLL chip. (The PLL itself isn't used in this circuit, just the VCO.)
The true resonant frequency of the coil when in the circuit you are using might vary a bit from the "bare" frequency determined in this manner. But by watching the scopetrace as you tune the oscillator you can tell when the coil is being stimulated at its resonant frequency.
