Contained in this video is another way of finding the resonant frequency of a stand-alone coil using the VCO section of the CD4046BE PLL chip.

When both LEDs are at max brightness the coil is being oscillated at its resonant frequency.

   Ok, thanks for the reply.
   It looks like the magnet in the yoke can change the frequency, especially to lower it, but the voltage I can only raise a little bit, yet the bulbs do brighten up.  Same thing with using ferite inside the Kacher former.  Those are my tuning pots, for now, along with ferite in the grenade former. For that to work, I need to be close to the right frequencies to begin with.

   Itsu, Hoppy: Good to hear that you're both checking out the Akula way of finding the grenades best resonant frequency.
   Have you tried to connect the earth ground line to the end of the grenade, like is shown, even a short one to see if there is any
influence the in flatline readings. 
   Should I wait to see what you guys can come up with, before borrowing a SG?

  BTW: What was the Ruslan way. No scope, no signal generator. Remember?
Now he has everything, but doesn't know just how to use it all, yet. Or doesn't need, to as he says.

  Is anybody going to try to make the PCB and build up the latest version of the Ruslan push-pull and Kacher circuits?

Nick,

well, if step 1 in Akula's methode of measuring a coils resonance is already not working, i think it is of no use to continue with the next steps (grounding one side etc.).


Its not sure if this latest version of the Ruslan push-pull and Kacher circuits are really being used by Ruslan.
They are "designed by ALLEGGA", and we have no info on him (relationship to Ruslan?).
But anyone who is able to make a PCB from that PCB layout, be my guest.

You could try this method: take your FG and connect it to a couple of turns of wire wrapped around the coil you are testing,

Hi Tinsel
If the target frequencies are in KHz range then this method is easy and close to reality. But if target frequencies are in the range of MHz, then these few turns around the grenade coil, introduce capacity and alter the true resonance freq and harmonics. This method is good to try when those few turns around the grenade are actually the inductor line itself which will not be removed after the measurements.

Itsu, Hoppy, John
I think that at Akula's way of measuring the resonance, needs to search for frequencies that decrease the overall response and not to increase. At least this is what i had realized while measuring my grenade. (Needs verification)

Hi Jeg,

yes, like a "grid dip meter".
But then Akula should have searched for minimum amplitude, instead he seems to hunt for maximum amplitude to find the resonance.
