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:

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

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.

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!
