Interesting that you used the *timing cap*, Pin#6 & 7 on the CD4046 as your *master_timer* for the TL494 *slave*.  Nice work!
Actually, that is the only innovative part of this circuit.  You spotted it immediately.

Instead of a *Passive_lag_loop_filter* for VCO input, I set up a LF412CN as a  *2nd_order_active_loop_filter* on the VCO input, the response time and dynamic range is exce9llent, I could see a visible difference over the first order lag loop filter I had tested before.
That is an original part, too!

Good Day Itsu

Yes, I have encountered the same *issue*.  The position of the _probe_ will affect the amplitude of and sometimes shift the resonant peaks.  Same with the position of the inductor winding............

I agree with you that the SA method using a Tracking Generator will give an uniform and integrated *picture* of the resonant points.  But, as mentioned above, positioning of the *Inductor winding* and for that matter it seems anything within the _near field_ of the Grenade will and does influence the resonant points.  So even when using the SA w/ TG, the *ultimate position of*, and *interaction with* any and all objects within the _near field_ cause a distortion of the virgin free space Fres (res. freq.).

Ruslan had mentioned, very long time ago, that the Grenade is a "Half wave Antenna @ 4Mhz"

I think a valid question would be:   Should the Fres of the Grenade be calculated and/or measured according to *free space* parameters, or should it include all *near_field* effects?

Anyone with access to a Spectrum Analyzer is going to see very rapidly that this *Grenade* is a virtual _can of worms_ to deal with.  I believe this is why there are so many different recommendations regarding how to wind it.

...................
I couldn't find the *modify* button either to correct my last post...........



take care, peace

LB,

yes, the grenade is very sensitive to nearby objects, so therefor i think a PLL kind of system is needed to keep it in resonance.

Concerning this:

it does not make much sense to me as a half wave antenne is normally a center fed dipole which could contain some coils to lengthen the wavelength or function as stops.
Especially when you think that the grenade is grounded at one side i cannot picture it to be a "Half wave Antenna @ 4Mhz".
 
Anyway,  nice build you made on the PLL system, i see it was on a breadboard as well.   Thanks for showing.

Yes Yes but is it relevant in the phenomena we are looking at get that first then you can play with tank coils.

Let's go back ab it shall we, and look at the yoke you need to find it's resonant frequency in the circuit (the oscillator driver and yoke, forget the rest, have you got standing waves ?  No that's your problem. crawl before you walk, walk before you run. Akula did a 30w porch light same principle.  Something about the yoke or torroid !!!

Ignore it and nothing work for it and you have the start of it.  EXPERIMENT !!!

I rewound my grenade so it follows the earlier in this thread mentioned layout, see picture below (no additional coils yet)

L1 and L2 (CW) are half the length of the wire (full length 36.5m in my case) and evenly split in half, but then they do not fully cover each other.
Same with L3 and L4 (CCW) they are 2/3th of the other half and also evenly split and thus not covering completly
Finaly same with L5 and L6 (CCW).

The SA output shows (without the inductor) a more even spectrum with 1 big resonance peak at 1.725Mhz.

Video here:  https://www.youtube.com/watch?v=_-4RjDt29zA


I will play around with the ground connection to see if that influence the resonance points.

Hi itsu,

Can you make Tesla coil from the aluminum wire and try to find on which frequency and voltage the quenched pulses are creating radiant response on the Tesla radiant receiver nearby?
This will give you idea on what frequency your grenade power receiver should be for when using same ground wire..

Cheers!

  I also find that at least on my push-pull driver, the copper on the PCB board itself is also picking up different interference. Which can transfer to the rest of the circuit on the board. Even placing the voltage regulators, and their filters on the same board makes a difference. The same negative effects were not present on the Mazilli driver, which was not using a board at all. Nor interference of the signals. The signals were clean, showing no peaks, nor strange wave forms at all. Just nice clean sine waves signals, with an output at the yoke of over 1000v with no load on it. Once the Kacher was activated the yoke's sine wave was ridden on by the HV Kacher circuit.
 
   Itsu, what value resistors should I use on the open yoke coils for the test that you suggested?  Maybe you can detail that idea a little more for me. And I'll give it a try.

   It's interesting what Verpies mentioned about your having better output on the yoke, as compared to the output on the grenade coil. As the number of turns on the 168t coil, compared to the 3t or 28t coil, as well as the additional rectifier circuit attached, the output should be the other way around. But, it may not be. I'll check that as well.

   However, it looks like the commercial TL circuit once modified with the trim pots was working quite well.  Or not? Specially if the load it kept steady, by not changing nor adding additional loads.
 
  It's the actual output at the bulbs that I look for, from the Kacher/grenade sync. And how well they work together to obtain any  additional gain at the output.
  On the Mazilli the voltage actually went up with each additional bulb added, and so did the Kacher's output to the grenade. As the Kacher was running off of the 28t coil, the feed back path could even run a laptop. But, did not self run the device. That was when I changed over to the TL circuit drivers, and lost most of the output that had previously seen at the my bulbs.

Nick,

Itsu posted a circuit diagram giving the resistor values back in his post 17321.

Nick,

with 100K resistors at 24V they should pull (I=U/R) 0.24mA and thus dissipate (P=U*I) 5.76mW, so any 100K value will do.
Even 10K resistors can do the job (2.4mA / 57.6mW).

T,   sorry  :( ,  but i won't be firing up any tesla coil / kacher as they cause to much damage.

Well, you have it next to the grenade coil and it is main part of the system anyway...

   Ok, thanks for the info. I do have a small bag full of new 10k resistors. I'll also recheck your posts. I think that it's important to check on the device, to see just where the power is being lost, and to help figure out what to do about it.
   Good to know that you're working along with Verpies on the modified PLL.

As the number of turns on the 168t coil, compared to the 3t or 28t coil, as well as the additional rectifier circuit attached, the output should be the other way around.
It is more about the coupling coefficient (k) between windings than anything else.
You can measure this coefficient by shorting one winding and measure the ratio of how many times the inductance of the other winding has decreased.  Ideally it should decrease to zero.

Here's a quick video of the final prototype up and running,  the scope only shows the complementary push pull outputs of the SG3525. 
What is your method of converting the AC sine waves generated by the LC circuit to square waves, without distorting their phase relationship (the 74HC4046 phase comparator expects square waves that are in phase when the LC circuit is in resonance) ?
I have found that if I use a voltage comparator with a hysteresis to do that, then the hysteresis introduces a phase delay....and if the hysteresis below 0V is different than the hysteresis above 0V, then the output becomes even worse, namely it stops being a square wave !

Without the hysteresis, the noise immunity of the sine to square conversion suffers dramatically !

hi all,
i have written yesterday a message , some attachements with it . I still have "Note: this post will not display until it's been approved by a moderator."  any help from moderator?
thinking that attachements may be the reason, request again assistance from  more experienced experimenters:
I'm driving a flyback transformer with 555  pwm/irf840. output of the flyback is feeded to a toroid via sparkgap and from the toroid just lighting one of 9w led bulb. amp reading (drwawing from battery ) is fluctuating -so i make assumptions for what is consummed with voltmeter across one 0.16ohm resistor in series with negative feed from batt. In normal operation reading is 130-160mv(so @1 amp) , but if I connect a gruonding cable to mosfet drain, voltmeter shows 30-50mv, abt 3-4 times lower. no changes noticed on light bulb, same noice on flyback and sparkgap appear to fire at the same rate.
I don't say is bad but why is happening? 555 pwm is powered from separate batt/supply. if I touch grounding cable to any other place than negative terminals(incl batt negative ) , comsumption is increasing.
any ideeas?
thanks/rgds
