Cytat z Wiki
Most modern audio amplifiers have a flat frequency response as shown above over the whole audio range of frequencies from 20 Hz to 20 kHz. This range of frequencies, for an audio amplifier is called its Bandwidth, (BW) and is primarily determined by the frequency response of the circuit.

Wlasnie sprawdzilem jak wyglada uzycie Wzmacaniacza audio Blaupunkt  PCA2120 2x120W 1x300W.
Podlaczylem generator sygnalow i uzylem wylacznie pozytywnej czesci pulsu sinusoidalnego niebedac pewnym czy
to cos dziala na sygnal przemienny czy tez tylko staly w postaci impulsow ( az tyle to nie wiem a szkoda mi tego wzmacniacza, moze w
nastepnym aucie mi pogra jeszcze :) )
Na wyjsciu oscyloskop pokazywal sygnal sinusoidalny a wiec to by moglo calkiem niezle dzialac przy 13-14volt i jakies 10 amper.
Niestety zgodnie z informacjami o wzmacniaczach audio wraz ze wzrostem czestotliwosci tracisz tzw GAIN. Jego mozliwosci wzmocnienia sygnalu znacznie  spadaja powyzej 120khz . A wiec wyciagajac wnioski moge spekulowac ze daloby sie zrobic Tesla coil na podobienstwo Slayer Exciter i kontrolowac czestotliwosc ale tylko na duzym lub bardzo duzym transformatorze ktory ma swoja czestotliwosc rezonansowa
w granicach 100khz i ponizej.
Wlasnie dlatego szukam mozliwosci podlaczenia generatora sygnalow do wzmacniacza ktory bedzie pracowac satysfakcjonujaco w przedziale czestotliwosci radiowych aby transformator Tesli nie byl duzy oraz latwy do zbudowania i szybkiej modyfikacji w razie potrzeby.
Dziekuje za pomysl i pozdrawiam


Skoro idzie modulacja na TT muzycznej to jasne jest, że teraz jest to pełny nadajnik. Ostatnio nawet na YT widziałem, że na FM jest normalnie przekaz muzyki co mnie nie dziwi.
Pomyślałem więc jeśli można tak to zrobić to jest to mega tanie rozwiązanie drogich wzmacniaczy na szerokie pasma bo my nie potrzebujemy tak dużych zakresów, a jedynie wąski obszar jak mniemam.
Zresztą to tylko dałem pomysł w oparciu o zdjęcia wzmacniaczy.

Recently, I read somewhere that Tesla, in an energy transfer experiment across the globe, used high power transmitter to stimulate the cavity. Carum brothers in an experiment on the river did energy transfer to the other side. Hmmmm it's not clear now what kind of wave they sent. By building the Viziv faith, everyone will agree that there will be great power in it, which suggests that in order to make the transmission that Tesla talked about you need to use the right large solution in relation to the earth!
The construction of miniature tesla coils may simply be impossible for transmission through a cavity of the earth and the resonance itself.
I may be wrong but these are my thoughts.

People from Ukraine made a transmission of energy and received an increase in output using special cone antennas. They have a 6kW device and 100kW for industry. However, I can't sell it because the Kiev authorities blocked it. Is this true I think so.

suggestion: when you have a river and a strong current, what will happen if you throw a stick? This is a possible answer for energy transmission!
Isn't that a beautiful explanation? Thank you.

Food For Thought......

http://www.capturedlightning.com/frames/Non-Herzian_Waves.html

This is a quote and you may disregard this article / publication because its perfect example how confused people are about
Tesla's Wireless Power Transmission System.

"Tesla often refers to energy being carried by the currents rather than by Hertian waves. For example, he writes

    "From my circuit you can get either electromagnetic waves, 90 percent of electromagnetic waves if you like, and 10 percent in the current energy that passes through the earth. Or, you can reverse the process and get 10 percent of the energy in electromagnetic waves and 90 percent in energy of the current that passes through the earth."

Straight away we see a problem with this. He is talking about a situation in which the reactive component of the field is to be much larger than the real components, in other words the intended destination is within the near field of the source (within say a half-wavelength to achieve the proportions suggested), or else both source and absorber are contained within a low-loss (high-Q) cavity. He is expecting the earth currents associated with the reactive near field to convey energy to his receivers independently of the EM field."


So the funny part is that he explains the process of a lanching a surface wave but still disregards its existence or possibility of its utilization.

The tesla coil can operate in two modes:
- voltage (V)
- current (A)

for V the effect is high HV
and for A high A.

This is not strange, but has anyone done such an experience and knows how to do it? I did such tests and I can say that Kapanadze could use the Tesla coil in mode A.

Hello Stivep and other forum members,


I am sorry to have to step in to clear up some misunderstanding.  If my memory serves me well, the main authors of this paper have already left to other countries a long time ago. I don't think this work has anything to do with Guangdong[size=78%].[/size]


I don't visit this forum very often but feel free to discuss, ask questions and share your knowledge with others.

From Wesley: Special  Thank you speedy125
please start reading from here:

This work was supported in part by the Guangdong Natural Science Funds for Distinguished Young Scholar under GrantTitle:
Title:
Wireless Energy Harvesting by Direct Voltage Multiplication on Lateral Waves From a Suspended Dielectric Layer

 Link: https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=8053760


From  part  #1  we have learned   that
-earth as    multilayered part of interface  is suggested.
-that is  in line  with Marconi’s early experiments,
-the paper explores the feasibility of wireless energy harvesting by direct voltage multiplication on lateral waves.
-we could also look at  picture  representing multilayered  interface
-  we  had the first look at wave behavior while  "loading" into  interface

From  part  #2  we have learned:
- the  differences  between  regular EM wave known also as Space wave and Surface wave.
- the 4 layer suggested   ground  as one of parts of interface Air/Earth
- the wave  in  the  interface  must  be  in TM  mode

From  part  #3  we have learned:
-  that  the thickness of both layers  of the  interface is expected  to be 1/4 of  the  wavelength Y

From  part  #4  we have learned:
Basic schematic   of  Avramenko fork and  voltage multiplier   that can be used at any frequency
in association with Goubau line or any other type of interface.

From  part  #5  we have learned:
 SIMULATED AND MEASURED RESULTS OF BASIC WPT (Wireless Power Transmission)CONFIGURATION
We can see from Fig.3b Fig.3c impressive performance   of TM in the interface.
=======================================================-this above is another confirmation of expected performance over the regular  EM wave
.-this above is another confirmation of expected performance TM  in the interface at low frequencies.
-this above is another confirmation of fact that this wave is not  present in Far Field 
The exact  statement  saying  it  is int the article I just must have time to find it

I went into the article.
I search who is Paul Nicholson  the guy  is mystery  to me.
 The REAL Science of non-Hertzian waves, by Paul Nicholson  no  original  link  to article was found

I happened to read the  reprint few years  ago  but it was not deep  study.
End of story is that  Article was likely published  in 2002.  the missing  are  the drawings he  referees  too.That is why his article-  reprint is somehow unclear.
The guy  had no idea  about  surface  wave and interface  as it was  at that time in  its infant  stage.
Definitely he was/ is educated  guy with nice English skills. 
He got few things  right and article is worth  reading.
Waveguide and lightning  is nicely explained,  however  again  his limitation is his approach based on lack of novelty of surface  wave science.
So my plan was to  contact him  or visit him  with some  suggestions.   

Along my search  I  got  few helpful links:
- http://www.tfcbooks.com/mainpage/links2.htm
- https://www.backyardastronomy.net/natural-radio-receiver/

"This last link  says thank you to  Paul Nicholson"

who  is  he? ??? ??

VLF receiver is nothing more than an audio amplifier attached to an antenna.
Quote
One of the most popular uses for a VLF receiver is for listening to lightning strikes from around the world,
and the interesting effects that this activity has on our atmosphere.
Quote
lightning strike is not a narrow band event as is say a military VLF transmitter like NAA in Cutler Maine at 24KHz.
These types of wide band signals are characteristic of natural EMF activity from Earth
The article  includes schematic and waterfall of Rx.
-https://physics.stackexchange.com/questions/132576/why-is-lightning-referred-to-as-high-frequency-source
Lightning strike
 
Quote
The negative flash/stroke is found to have 200KA of current with a voltage close to 300KV (cloud to ground).
According to wikipedia, average duration of a lightning is 30μs. If we take a gaussian current splash with σ=30μs,
its spectrum will be a gaussian with σk≈33kHz.
-https://en.wikipedia.org/wiki/Schumann_resonances
Quote
Lightning discharges are considered to be the primary natural source of Schumann resonance excitation;
lightning channels behave like huge antennas that radiate electromagnetic energy at frequencies below about 100 kHz.
-https://www.qsl.net/dl4yhf/spectra1.html easy way  to receive ULF .

Especially interesting  is this link:
http://onlinelibrary.wiley.com/doi/10.1029/2005GL023028/full
Detection of thirteen resonances of radio waves from particularly intense lightning discharges
So  we know from all of links  above  that lightning is  responsible(mainly) for  Schumann   resonances and
lightning by itself is  the source of its  own  resonances  and its harmonics separately.

With that we may ask what  happen if EM wave at right tilt angle and polarization hits the earth?
Will  it land  in the interface?
Can we help EM wave to do what we what it to do  by Kapanadze process of activation?
https://youtu.be/XOTLfnMOSqQ?t=993

Quote
Lightning strikes reach the ground on Earth as much as 8 million times per day or 100 times per second,
according to the National Severe Storms Laboratory.
and we know that we need   50/60Hz per second for our electricity in our outlet.
Random amount of EM  waves  per second  produced by  lightning  with right  properties  to land in the  interface
can be  calculated.
Than this energy can be  received stored in capacitor and rectified.
The only  why we  use  AC is that is convenient but DC is used by most if not  all of  our  portable devices  also  by choice of convinience

Hello

As you noticed im just an amateur and curious person who likes to learn stuff.
Now i turn to you seeking a simple explanation and training.
Do to lack of financial resources i can only afford simple and cheap tools i can find on ebay.
Im using this simple usb oscilloscope Hantek 6022be . It is easy to use and fun to learn and
explore options and possibilities given by such tool.

While playing with frequency counter option  i noticed it shows me two different wave forms.
Im trying to determine frequency of my slayer exciter and at very low power ( 3-5volt input) i keep the probe pretty close to a top load.
While i change top loads it adjusts to different resonant frequencies.

So im using this software provided with the device and when i use stop option at longer time frame lets say 50us
it shows this modulated like wave . still i can measure frequency and its the same as i take shorter time frame 10us  but wave form
is regular sine wave.
What does it mean and why i see two different wave forms?
Tesla coil is top loaded and grounded and slayer has feedback antenna coil to pickup the signal . When i played with single wire
transmission ( top load - coil - capacitor -- copper wire -- capacitor -coil - top load ) i could see same different wave forms so ground
didn't change anything.
I consider probe leads are cheap, is this the reason and which wave form is true ?

Thank you

Good morning Wesley,

I have some concerns in moving forward to the next step of wireless transmission.
Since it involves using earth ground instead of the nice shielded coaxial wire I've been experimenting with.
My concerns are, as soon as I connect the TC secondary bottom wire to earth ground it dissipates the high voltage everywhere in the ground like a massive sponge.
The results are a mostly dampen signal to the TC top capacitance. So how can one expect any wireless transmission?
Also not clear is, the earth grounds quality!... as I have already demonstrated, in my location earth grounds are very bad due to the sand.
How good does the ground need to be?

Apparently Tesla had multiple grounding rods hundreds of feet deep below his Wardenclyff tower plus the location is on a shore to the Atlantic Ocean.
What did the Viziv project use or do for earth ground?

Kind regards
Luc

I'm sorry  but   in the car now
so I answer  it short and may be not that precise as you  wish.
 
I suggested you to go step by step.
Don't  jump ahead.
It is  a learning curve.
From Goubau   line  the next step is to buy cheap aluminum foil  and make experiment .
https://overunity.com/18335/wireless-energy-transfer-experiments-builders-board/dlattach/attach/174200/image//
https://youtu.be/XOTLfnMOSqQ?t=367

Quote
Types  of interface:
-e.g
- Goubau  line uses  wire coated with   dielectric and that should be   named  the interface, but it is not.
- two dielectrics differing  with their  dielectric properties   such  as Teflon  and Polyamide  makes interface
- conductive medium such as  aluminum foil  and  air creates  interfaced as well
- lossy conductive  medium a such  as earth   and air creates interface too
and so on...
After you  are successful with that   it is helpful to
use  spark gap instead  of    Generator  and  adjust spark electrodes  distance .
That  gives you comparable  results   .Because spectrum  of spark generator is wide  than  you don't have to be worry  that  system is unstable
there is enough  of Adjacent frequencies  in the  spectrum  to  take  over .

Quote
Failures:
The failure   of your experiments  can be caused also by:
1. lack of impedance  match.
2. lack of proper  polarization AND BREWSTER  ANGLE - that is done (at its easiest)  by  changing elevation of top capacitor . HV Tesla coil  must be vertical to the  ground 
3. lack of resonance in both  the Tx  and Rx  Tesla coils

This is a very important question which I asked twice and never got an answer.
Let me help us two a bit and provide a clue:

This lateral wave is a vertically polarized electromagnetic wave on the top surface of the ground as a result of an incident electromagnetic wave striking the air-ground interface from below at exactly the critical angle [16], [17]. For an interface between two different dielectric media, the critical angle is only applicable to the dielectric medium with a higher refractive index.To excite this lateral wave, it is logical to bury the lower end of transmitting and receiving aerials into the dielectric layer with a higher refractive index in much the same way as grounding a monopole antenna in Tesla’s or Marconi’s work .

No simple answers available.

 Link: https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=8053760

When you read about  this experiment https://arxiv.org/pdf/1903.10294.pdf you see a different mechanism ,
 mainly "Sinking of Equi-phases"
Whatever you read it points you in a whole new direction . unless its all the same???
