Litmotor:
   The first step was attempt to correctly document Dr. Stiffler's energy lattice formula.  An analysis of the formula is needed as TinselKoala points out, also the empirical data that Dr. Stiffler mentions in the video needs to be
replicated which he states confirms the formula but provides no further details.  It would be good to know if an L3 circuit tuned to the 13.5 MHz frequency which you use has a more efficient output than an L3 circuit tuned to a
frequency that is not near an odd integer frequency.  This is probably the type of empirical data Dr. Stiffler is referring to, for example, common crystal frequency 11.2896 MHz is roughly centered between odd integer
15-10.6592 MHz and 17-12.0804 MHz.  A good test would be to check the L3 tuned circuit efficiency difference between 11.2896 MHz vs. 13.5 MHz or 11.2896 MHz vs. 12 MHz, the frequency NickZ uses.  If Dr. Stiffler's energy
lattice formula truly calculates the frequency at which the energy lattice will release energy I think this test results would provide valuable data.

Itsu:
   The tests that you demonstrated peaked my interest to further test and try to understand the frequencies that resonate with the L3 coils.  The FFT function of an oscilloscope can be very helpful to visualize resonant
frequencies and it is also a good way to monitor coil tuning and how changes affect it.  As time allowed I used the FFT feature of my oscilloscope to replicate your tests from this video https://www.youtube.com/watch?v=FhGx8TYs0Iw
and saved screens to document the srf of some L3 coils.  I setup an FG to sweep from 0-50MHz with 1Vpp sine wave and the oscilloscope FFT was setup to monitor from 0-100MHz using a Max Hold feature.  I've attached a picture
that serves as a reference to my setup with file name L3 srf Test Setup.  I'm primarily working with four L3 coils (D and E are to spec, J and K each have different number of windings).
   I've also attached some FFT screen captures with the sweep frequency at the top and dBm on the sides. The file name notes the test setup:

srf1 FG-L3D(FFT)- > FG directly connected to (a) and FFT oscilloscope probe capacitive coupled to (c) per setup reference using only first coil
srf2 FG-L3E(FFT)- > FG directly connected to (a) and FFT oscilloscope probe capacitive coupled to (c) per setup reference using only first coil
srf3 FG-L3D--L3E(FFT)- > FG directly connected to (a) and FFT oscilloscope probe capacitive coupled to (g) per setup reference without 100 ohm resistor
srf4 FG-L3D-R100-L3E(FFT)- > FG directly connected to (a) and FFT oscilloscope probe capacitive coupled to (g) per setup reference with 100 ohm resistor as shown in picture

   This first group of tests have the L3 coil open at the top end and are capacitive coupled to achieve the highest standing wave resonance frequencies from a reflected quarter wave.  I set the insulated tip of the FFT oscilloscope
probe up against the last coil winding at the reference point shown in the test setup picture.  The coil(s) and test probe were positioned precisely the same way for all tests. 
   I used a lower level FG 1Vpp sine wave and the FFT probe was set up against the last L3 winding, so this would explain the lower L3 resonant frequency compared to what you got.  You showed how moving the probe away
from the L3 coil increases the resonant frequency.  These test findings were similar to yours, I also don't understand how connecting two L3 coils in series results in a second resonant frequency that is higher than for a single
L3 coil.  I welcome comments from anyone that will help to better understand this.

iQuest,

very nice experiment.

So i see a 0-100Mhz sweep, with the first 2 screenshots showing a peak around 18MHz for both L3 coils used
(indeed probably higher if you remove the probe somewhat).

The next 2 screenshots show those same two L3 coils in series (with and without a 100 Ohm resistor inbetween)
which give two peaks around 10/11 and 24/26MHz.

I remember i also "saw" these double peaks, allthough the first peak was lower (3.5MHz) in frequency, see:
https://overunity.com/17249/dr-ronald-stiffler-sec-technology/msg524779/#msg524779


I think the Doc. is trying to simulate "ground" by using the 100 Ohm resistor




A possible explaination could be (using http://www.1728.org/resfreq.htm):

My L3 coils measure 27uH, so the self capacitance (resonance at 24Mhz) calculates to be 1.6pF

Two L3's in series will give 2x 27 = 54uH and 2x 1.6pF = 3.2pF giving a resonance of 12Mhz.
So perhaps we see both resonance components emerge on the traces.

(i know that 2 equal capacitances in series give half of their value, but i think that the selfcapacitances
are in parallel with the coils, so behave differently,   food for thought).

   Gyula:   I now have the crystal oscillator reworked, although it may look similar to how it was before, it is not the same.
   There are 8+8  4148 diodes in a single diode loop, lighting a 24 led AC led bulb.  Plus another 26 led board in parallel, also.I'll be adding the second diode loop, when I get some more diodes.  The voltage at the AC bulb is 98v now, while the voltage at the oscillator's collector/emitter is about 48v, with a load.
  The unloaded voltage at the AC bulb, (but with the bulbs all removed) is about 150v, or so.

   My transistor is only a 100mA model, so I'm doing what I can with that limitation, for now.  The input voltage is 24v from batteries.
   The AC led bulb is not gutted, so there is still a circuit inside, which limits the input current and voltage. Which is probably why the bulb is not lighting as brightly as it would without that limiting circuit.
    I'll be getting 4 new AC 8.5w LED bulbs today, if all goes as expected. New tests will be done once I gut them to remove their  circuits.
   
    Although my multi-meter does not register the amp draw now, it still works to read voltages.
   
    As usual, any thoughts or ideas are welcome.                                                                           NickZ

Hi iQuest,

The formula  cannot be complete, something is not disclosed because the dimensional analysis does not
give frequency as TinselKoala mentioned it. I tried to analyze it but my rusty brain has given no wise outcome
how the Hz may come out. The first character on the left side of the equation symbol can be the last but one
Greek letter of the Greek alphabet (uppercase): Ψ  (Psi).  Why the Doc chose it for frequency may or may not
have significance, I would not be surprised if it were to cover a certain expression to make the dimensional
result correct.  (this latter is just my speculation)
On the question how the connection of two (identical) L3 coils in series may result in a second resonant frequency
that is higher than for a single L3 coil:I think first we need to understand that the first L3 coil
(that is driven from a generator or from an oscillator) is detuned in a greater degree (to a lower frequency)
than the second coil that is connected to the free end of the first coil.

Why can this be so? I think the explanation is the body of the generator or oscillator has a much bigger surface
embedded into the 'space' around them versus the surface of the first coil wrt the second coil.  So the two coils
are never tuned to the same resonance even though you did your best to make them as identical as possible.
OF course the detuned frequency of the first coil could surely be corrected with careful fine tuning, has any of you
done so during such tests you are showing?

So I suppose the first coil has the lower resonant frequency because it is more detuned by the generator than the
other coil, you can also check this.
Or try to fine tune the second coil which I think has the higher resonant frequency wrt the first.
Question is if you tune the resonent frequency of one of the coils to coincide with the other, then will you have
a single peak instead of two?
Does the second coil have the higher resonant frequency wrt the first?
If you test these to see the behaviour, then more answers will come from the tests. 

Also, consider the following:  say the first coil will have 2 pF higher self capacity due to the direct generator
connection, i.e. say it will have 4 pF, while the second coil will have only a 1 pF increase in self capacity i.e. it will
have 3 pF provided each has 2 pF self capacity alone when not connected to anything. 
There will be a resonance the L value of the first coil creates with the self capacitance of the second coil and
vice versa: this should normally result in two notches in the response with a peak in between if two such
detuned series tanks are swept between two 50 Ohm (or any other value) terminations.   
Hi Nick   All I can say is carry on.

Itsu:
   Appreciate your input, I was sweeping from 0-50MHz which is the maximum for my FG and with FFT I was monitoring sweep frequency and  harmonics up to 100MHz.  In the first group of tests the L3 coil(s) had an open end opposite
from FG so I was expecting the frequency peaks to be from reflected standing wave not from LC resonant frequencies.  I see your point and what Gyula has posted but I'm also trying to account for standing wave at quarter wave
resonant frequency with this open ended circuit.  In the tests with and without the 100 ohm resistor the two peak frequencies decreased when the 100 ohm resistor was installed, it is most noticeable with the peak at the higher
frequency.  Installing the 100 ohm resistor in series increases the electrical length so a lower standing wave frequency would be expected, as appears to occur.  But we have also noted that the closer the capacitive coupled test
probe is to the L3 coil the lower the frequency, so both electrical length and capacitance appear to be major factors in the change in frequency.  I think an important question might be: Is the change in capacitance affecting the
standing wave velocity factor and thus this resonant frequency, or the LC resonant frequency, or both?
   I'm taking a methodical approach, so before moving on with tests using direct FFT connection I conducted another test without the 100 ohm resistor.  For this test I replaced the resistor with a jumper wire of the same length to
keep the total electrical length of the two L3 coils the same.  The peak frequencies do remain the same with either the resistor or a jumper wire of same length confirming that in the previous test the peak frequencies were higher
when the series resistor was removed because the total electrical length of the two series L3 coils was shorter when they were directly connected together, the 100 ohm resistance was not a factor.
   I also thought it would be good to conduct this same test with a small top load so I connected an AV plug with one white LED to the open end of the two series L3 coils to compare the 100 ohm resistor vs. jumper wire while
maintaining the same electrical length.  I didn't learn anything new when the LED load was connected, the resonant frequency decreased due to the increase in electrical length with a small drop in amplitude but the resistance
does not appear to be a factor in this test.  The LED lights up at both peaks when the FG sweeps at those peak frequencies, much brighter at the lower frequency peak which has a higher amplitude.  The FG was kept at 1Vpp
with sine wave output and I continued to position the coil(s) precisely the same way.  I've attached some FFT screens that I saved to document the frequencies and amplitudes with the various test setups, each file name notes
the test setup with references to the previous setup picture:

srf5 FG-L3D-R100-L3E(FFT) >  FG directly connected to (a) and FFT oscilloscope probe capacitive coupled to (g) per setup reference with 100 ohm resistor as shown in previous picture
srf6 FG-L3D----L3E(FFT)- > FG directly connected to (a) and FFT oscilloscope probe capacitive coupled to (g) per setup reference with jumper wire of same length as the resistor that was removed
srf7 FG-L3D-R100-L3E(FFT)-LED > FG directly connected to (a) and FFT oscilloscope probe capacitive coupled to (g) per setup reference with 100 ohm resistor and an AV plug (two 1N4148 diodes) with one white LED connected at open end
srf8 FG-L3D----L3E(FFT)-LED > FG directly connected to (a) and FFT oscilloscope probe capacitive coupled to (g) per setup reference with jumper wire and an AV plug (two 1N4148 diodes) with one white LED connected at open end

Gyula:
   Also appreciate your input, you make very good points that I need to take into consideration when reviewing my test results and setups.  I had noted in a previous post that Dr. Stiffler used two different size L3 coils in the video
where he connects them in series with the 100 ohm resistor, perhaps he is tuning them to the same frequency as you describe.  I have conducted some tests with the two different size L3 coils that were pictured in my last post,
I will share those test results in a future post when I get a chance to spend more time with my equipment and will further followup with you then when I've given more thought to your comments.  In the mean time I would appreciate
your input on my above comments to Itsu.  In the tests I've shared so far with single coils and two coils in series I have noted that a small change in the total electrical length will change the peak resonant frequencies.  Dr. Stiffler has
emphasized  this in some of his old videos.  A standing wave is at play here, as would be expected on a transmission line with an open end.  I'm trying to distinguish between standing wave and LC resonant frequencies and to better
understand their relationship in this circuit.
