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 .

Types  of interface:
<sub>-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...</sub>

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 .

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.

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???
