Thank you Gyula!

Attached please find a revised estimate of an upper bound for the output energy from the function generator in Lidmotor's test.

It remains to estimate the energy dissipated in (coil  +  AV-plug  +  LEDs). But if it works with a 1 K external resistor R the output energy from the function generator would be less than 0,05 Watt which is for sure less than the LEDs need to shine brightly (49/1050 = about 0,05).

If the function generator test works with a 1 K Ohm external resistor, OU (or energy from the environment) is very likely. I am still very engaged in playing with stepper motors and gyroscopes, therefore I do not want to go into Stiffler-stuff. But Lidmotor could easily try some external resistors in his function generator tests.

Greetings, Conrad

Hi Conrad,
Yes, that is okay now. 

By the way, I believe this is the generator (FeelTech FY3200 series) Lidmotor uses and here is a good review on the generator
https://www.youtube.com/watch?v=EZ-i6lOTT9k
and the user manual is here:

A notice is needed when using say a 1 kOhm resistor in series with the output of a generator: at 13-14 MHz frequencies, the quality of a resistor does count because a 1 K resistor is simply not a 1 k resistor any more but can be less due to the combined effects of its own parasitic components like mainly self capacitance and inductance which may gradually shunt the resistor.  Carbon and maybe film resistor types or so called inductance-free resistors should be used when meaningful power measurements are to be made around 13.5 MHz.

Hi Lidmotor,

Thanks for showing the test with your nice generator at a different frequency than 13.56 MHz. I suspected such setup may give similar results at other frequencies too, see my opinion on this here https://overunity.com/17249/dr-ronald-stiffler-sec-technology/msg522662/#msg522662  and here https://overunity.com/17249/dr-ronald-stiffler-sec-technology/msg522415/#msg522415 

These results do not rule out the views and findings Dr Stiffler holds or maintains on this setup of course, especially his finding that the P-N junction of LEDs can be excited by RF fields via a metal plate placed very closely behind them so that the junctions are capacitively excited. And the LEDs need to be connected in series and their circuit should be closed by two diodes to let current flow happen.

All----I finally got my cheap function generator in the mail and got it to do a true replication of Dr. Stiffler's experiment.  The
Wiper Coil' I made was critical in getting this to work at 13MHz.  This effect does work at other frequencies depending on what coil you choose.

Hi Itsu,

To check the correct tuning of the toroidal tank, you could use say a 2-3 turn loose coupling coil wound on the toroid to monitor the amplitude on the oscilloscope when tuning the trimmer capacitor for maximum, this way you can remove the probe self capacitance from the tank and the tuning can be correct also for the collector-emitter waveform test.

I suspect when the 5 kOhm trimmer pot has a certain value other than full zero Ohm, the voltage drop across it changes hence the transistor matching to the tank (operational point) also changes when the loading effect of L3 appears at the collector as you tune L3 to resonance, this may cause what you find.  You may wish to use say only 5 - 7 V supply instead of the 12 V battery for a test to see whether this strange behavior develops then  (no 5 kOhm or just short circuit it).

Regarding the brigthness getting less when you tune L3 to 13.56 MHz from its own frequency of 15 MHz may indicate the ferrite is already a bit lossy at that frequency? (unless you know its specifications but this is minor issue at present)

Thanks for your kindness.

Gyula,

initial test shows that removing the probe from the toroid output and changing it to a 2 turn loose
coupling coil, the trimmer cap needs to be full (23pF) to show some oscillations.
Connecting a second probe to the collector/emitter stops the oscillations.

So think i need to have some more capacitance in the tank to work without the probe attached.

Anyway, reconnecting the probe to the toroid output and using the 2th probe across collector/emitter
shows the below signals:

(Blue is the collector/emitter signal, yellow again the toroid output).

Hi Itsu,
Unfortunately, the probe capacitance can affect the resonant frequency of the tank, though in a smaller way because the collector is tied to the tap and the emitter AC wise also connects to the positive rail via the internal impedance of the supply and any filter cap across the supply rails.  But this probe issue can be fine tuned by trial and error.
Thanks for the collector waveform. I think it will still change a little when the tank has the correct resonant frequency. I indicated the distance between the zero and the minimum collector voltage, it is about 2.5 V.
