First thing what frequency is Katcher running at ?
What range does inductor push-pull run at ?
and what is the band with the response of scan coils?
and what circuit did you use ?

what's wrong ?
would be grateful if any advice is given on creating the interference between the Kacher/Tesla and the push-pull.   ??

decided to re-build the device again that I've failed to replicate 2 years ago.

I've rewound the grenade MAIN coil. now I'm gonna to wind the inductor on the grenade MAIN coil. I have some questions regarding the device:

1. The grenade coil I'm using now is 37.5 meters. Does the wire length of the inductor coil have to be half of 37.5 meters (=18.75 m) ? Is it OK to use 10~11 m wire length?
2. I've seen on some of the device schematics that the ground wire should also be 18.75 meters. Is it a MUST? I live in a high-rise apartment, about 20+ floors, can I use a shorter wire (for example, a few meters) for the ground wire?

thanks a lot.

The first thing that I see that may be not right, is the Kacher secondary. It is too long, and it's self resonant frequency will be too low. So, there will be little interaction with the induction circuit. The Kacher needs to be tuned to self resonate at about 1.5MHz, not 700KHz or so.  This will also depend on what frequency the grenade coil is running at, for a proper match up. I would try to tune the grenade to where it puts out the highest output, then tune the Kacher to it's best interaction to the best found grenade's frequency. This will vary with every device.
   No self runners are running at the same frequency, that I've seen. So, to me it's not a matter of a certain set frequency match, but finding what frequency works best for you on your device. This match up is the most difficult part, and where everyone fails. 
   If you use a 37.5 grenade output coil, the inductor should be 1/2 of that, or 18.7 meters long. 
   You may have to cut some wire turns off of the Kacher secondary. More or less about 1/2 the turns of what you are now showing. You can also make the kacher secondary with different tune able points along the coil. 
  The earth ground line should be the same size as the grenade output coil, or 37.5 meters long. Best to use thick welding cable. You can also use a old car battery negative rail as a virtual ground, in your case. Or connect the ground line to a water pipe. May not work as well though. But, you can also coil up the long ground line as some guys have shown, so that it won't take up as much space.  Let us know how it goes.
  Good to see someone back into building up this type of device, once again. Mine is only waiting for motivation to continue.

  One of the things that I've noticed is that when the feed back circuit is also connected up, the frequencies can change. And everything will change and one may need to retune. So, it's best to have a feed back path connected up also when you are doing the final tuning of the device. Or you'll have to do this later as you will probably see how it changes things.
Anyways, keep that in mind.

to AG:

so the wire length of your inductor is 20m/18.75m? That will be 4 layers, which is different from the Ruslan's (2 layers).
What about the length of your ground wire?

also, did you use the 28T winding on the yoke? In some schematics, the 28T winding is rectified and filtered to power the kacher/tesla. In some other schematics, the 28T yoke winding is connected in series with the grenade MAIN winding.

to all: no the inductor winding is a 9.375 if grenade is 37.5 meters have you looked on Stalkers site ?

about the failed replication years ago, a MOSFET-driven kacher is used, powered by a boost converter, with ground wire connected to the negative power rail. The base of the tesla secondary is connected to the driver chip (UCC37322) that drives the MOSFET. The EN pin of the driver chip is connected to the control board to trigger it. There were no 28T winding on the yoke, and only the 3T winding is used to drive the series C+inductor. The grenade MAIN winding is directly rectified to power the load. The control board (PLL was not used, 4046 used only as a VCO) that I designed has a huge drawback, that is, the pulse width of the push-pull driving signal is not adjustable and is fixed at 50%. By experimenting the setup, I found something strange, which was, the MOSFET-kacher can be triggered to self-oscillate at the [positive period+negative period] or [positive period only] but it cannot be triggered to self-oscillate at the [negative period only]. I did not see any interference between the kacher/tesla and the push-pull. By turning on the kacher/tesla with the push-pull already running, the bulbs only lighted up a little and the increment of light output can be barely seen (might be equivalent to a few voltage rise in RMS).

so I'm now wondering if the important points are [28T winding] + [HALF wave rectification] + [less than 50% pulse width of the push-pull] and decided to re-replicate it.  and maybe the kacher/tesla should also be tuned to the resonant frequency of the grenade?

Is there any other points to get the amplification effect?

Your best bet is to ask 'COLOR' he is an expert and knows all the tricks involved and has built a few that work
I strongly advise you to contact him if you don't want to go up any blind alleys ! as no one on here other than Color really knows!

1/4 of 40m is 10m and you can tune it all with capacitors think of it as a radio receiver. 37.5 m is 2 MHz at 1/4 wave not 1.5Mhz
1.5 Mhz would be 50 meters of wire.
