Hi Conico,

i used your method, but cannot get it to work, i mentioned that.

So i tried what the Russian guys did in the video i (and Justawatt) presented using a 2-channel FG driving a push/pull circuit and that worked and showed that dancing wave.

Hi Itsu,
My FG has two channels but I only used one I'm sure I used only one frequency. You made a mistake, you just had to give a signal on the inductor to start from 1500Khz and go up to 1650Khz to see where the grenade signal dances.
You use two frequencys but it's work with one too because you have two coils and  one can be a mirror for the  other one.
I don't use load or you can use a Higher impedance load.

   Does that mean that you can't get the dancing wave at 15 to 20KHz, like the normal grenade inductor frequencies.
  What positive results will happen between 1500 to 1600Khz? Other that dancing waves...without a load.
  And what will happen when the Earth ground line is connected up to the dancing wave frequencies. It will change things...as well as adding a load. All these things will change the running frequencies.  Or not?

In your case , something distroy the mirror betwin coils.
You can do something else. Use push-pull with TL494 on inductor and the scope on grenade  Someware the signal from grenade will dance. Go from 10Khz to 60-70Khz

I tried that too, large frequency range, low voltage on the MOSFETs all the way up to 30V, but it stays stable, but i will try some more tonight.


But while playing with my TL494 / push-pull circuit, i was mimicking some feedback / oscillations on the TL494 circuit by touching with a metallic screwdriver some of the pins (pin 6), and was able to create this dancing wave.

So i strongly believe that MOST of the dancing wave signals people have seen are coming from inadequatly shielded / decoupled TL494 (or any PWM) circuit.

See (hear) short video: https://youtu.be/ro3e1gevHAw

I believe that bulb destroy the mirror signal  Inductor give a signal to grenade and like a mirror grenade sent back a signal but not so strong. That why we see dancing signal in amplitude
Your setup is exactly like mine setup , except the bulb. Will you try without the bulb and no load at  all?

Nick,Ah! you say that to most of the guys, Ive seen it time after time, you don't want to help out any one, why are you so aggressive ? do you suffer from hypertension ? get it sorted out or buy a book on how to win friends and influence people. Just cool it and muck in with the rest of us and help out.

No you don't Know the working frequency, It must be were you find a dancing wave.

Conico I'm glad you came up with that one because retrobates didn't  Have you a link to Akulas video on that subject please advice ?
he used an earth and an SGen if it's the same one i'm thinking of,
