Yes, this would be a good next step in exploring this.  I think the oscillator will become and function
as an RF mixer too. 
Provided the second crystal is willing to oscillate too, in parallel with the 13.56 MHz,   that is...   8)
You may happen to have crystals with say a few MHz less frequency than 13.56 MHz.
 And for a start, just use a single 13.56 MHz and another single crystal only, say with having a lower frequency.
Gyula


TK,  Gyula,

nice experiment, and i agree with Gyula that the oscillator will become a mixer too.

Using the normal 13.56Mhz crystal in screenshot 1 
Adding a 12Mhz crystal parallel to the first one, see screenshot 2.

I had to increase the input current to around 50mA before the 2th crystal would start.
Will try some other frequencies later tonight.


These extra peaks goes for all the harmonics too, so the whole spectrum becomes a littered with spikes

I ran my one wire energy transmission experiment again using just a 13.6MHz sine wave signal from a function generator and it worked.  The results were not as good as using the crystal oscillator however. 

Gyula-- I mentioned your name in the video and I apologize if I mispronounced it.  I did some research on mutual inductance and you are right about how it relates to what I am doing in these multiple coil experiments. 

erfandl---I tried the multiple crystal experiment on my oscillator circuit briefly.  I did not see any significant difference visually but perhaps there was a difference in the power draw.  It was just a quick test and I didn't do any measuring.

TK --- Your idea about mixing the frequencies was interesting.  I'm wondering if I can inject a signal into my 13.56MHz crystal oscillator output using my function generator.  If we got lucky there might be a compounding wave happen like a freak wave in the ocean.  Just guessing.

Here is the video of my 'hallway' one wire experiment using a function generator:

PS--Here is how a freak wave forms in the ocean.  Maybe we can do this electronically ?

Lidmotor, 

nice idea to inject an extra signal with the FG into the Xtal oscillator.
This speeds up the process of trying multiple different crystals.

Using a 100nF ceramic cap to inject the FG signal into the base of the resistor.
4Vpp sine wave ranging from 350Khz to 26Mhz creates many different patterns of signals on the SA.

itsu---  Thanks for trying that experiment of injecting a separate signal.  I was hoping for a massive tall spike to show up when a second wave showed up at just the right frequency. It doesn't look like that happens.  Perhaps if there were multiple frequencies but that is hard to figure out where to even start with that experiment. 
  Thanks again for the effort.

Lidmotor, 

i see what you mean, but there are so many tests done in the past and now involving 2 signals being mixed
that if there is a special combination that produces something like an electronic freak wave it would have
been found by now, i think.

But you never know so there are still some parameters to meet i think like should those 2 (or more) signals
need to have the exact same amplitude (which is hard to do with a FG and X-tal osc.) and should the difference
in frequency be a few Hertz or kiloHertz etc.

Hi Itsu,

Okay, so it seems your SA nicely shows the multiple output frequencies of an RF mixer and we can be sure the displayed amplitudes at their specific frequencies are present at the collector of the transistor, it is reality.

Regarding your 12 MHz crystal needed a higher input current: although there is the so called 'activity' (willingness to oscillate) behaviour for crystals in general (they are all 'different'), have you tried this: just start the same oscillator with a single 12 MHz crystal and try to run it with say 15-20 mA input current only to see how it behaves. If it is willing to oscillate 'normally', then plug in a single 13,56 MHz crystal in parallel with it and see it oscillate or not etc. Of course it is possible you find the need for increasing input current again to have both crystals work, you will see. Try a 2nd or 3rd 13.56 MHz xtal (one by one) instead of the first one if you find the need for increasing input current to have both crystals work.
And if you happen to have other crystals of yet differing frequencies, do test them when you have time.

We may deduce from your tests now why the SA is not able to display the multiple output frequencies of the 2 or 3 or 4 or 5 pieces of the 13.56 MHz crystals in parallel: the outputs of the frequency components due to the mixing process simply coincide. This means that say the sum of two 13.56 MHz xtals is simply almost equal to the 2nd harmonic, 27.12xx MHz, the small difference may range from some 10 Hz to some 100 Hz (up to some kHz at the higher harmonics) only, so that the SA resolution is simply not fine enough. I think it is the RBW (Resolution Band Width) setting on the SA which can only be reduced to a given smallest setting. depending on sweep time (SWT) or frequency span etc.  The RWB was set to 30 kHz on your SA when you zoomed in on the 13.56 MHz frequency and probably a 10 Hz or less RBW would be needed to see the different frequency components which differ from each other by say 34 Hz. Of course this 10 Hz RBW or less may be a strict requirement for an SA, though not impossible.   

Thanks, 

Gyula

Hi Lidmotor,

Yes, when energy is taken from a resonant LC circuit (i.e. from the 'L3' coil) by coupling to it another resonant LC tuned to the same frequency (or to a frequency close to it within the bandwidths involved), then the one wire energy transfer suffers: you 'tap' its source.

You may find this link interesting:  https://en.wikipedia.org/wiki/Grid_dip_oscillator  and this link on how to use it: https://www.electronics-notes.com/articles/test-methods/grid-gate-dip-oscillator-meter/how-to-use-gdo.php

If I may suggest another link: https://en.wikipedia.org/wiki/Absorption_wavemeter  and this video: https://www.youtube.com/watch?v=fOnlyU2Qlwg

Regarding your freak wave example, I will return to it later tomorrow or so.

Thank you for mentioning my name in the video. To pronounce it 'correctly',  say the word  'due'  for the 'Gyu'  (the 1st) syllable and add to it the 'la' syllable (which sounded ok).

THE ELECTRONIC FREAK WAVE PHENOMENA HAPPENS IN THE KAPADNAZE CIRCUIT. BUT HE USES
SWR TO GENERATE THIS.

I SEE THIS HAPPENING ALMOST EVERY DAY ON THE BEACH ON PRASLIN SEYCHELLES.
FREAK WAVE THAT IS.

I ran the drain supply all the way up to 15V, with 0.96A DC input current, yielding 14W RF output.  Not bad for active devices barely visible to the naked eye, and no heat sink!  (EPC says R(ja) ~ 100C/W.)  I wish I had better efficiency numbers, but I was measuring rms load voltage with my Rigol scope, which isn't terribly accurate:  I was calculating drain efficiency ~ 96% or even higher, awesome... until I started getting some "over unity" efficiencies at low power (http://www.eevblog.com/forum/Smileys/default/facepalm.gif)  Oops.

Hi All


To get your nice high spike you need the same frequency from two sources combined in free space with the same phase, polarisation and amplitude; Some here know I have been working on this.

Hi all. today I build another circuit and paralleling two circuit together. the light output is now 2x (super high brightness) and current is about 50mA @24 volt. when I receiving parts as soon as I build 4 circuit and test. also there is no need to using ferrite rod

Hi all try sticking your crystal in this circuit if you want harmonics!

erfandl----What you just did is exactly what crossed my mind about paralleling two complete crystal oscillator circuits.  I didn't think that it would do much---and you proved me wrong!  Great results!  I have all the parts to do this and will replicate your experiment as soon as I can.  Your lumen per watt situation is starting to look really good.  Looking at this on a scope and spectrum analyzer should be interesting. Perhaps the big freak wave I am looking for happens with this simple two circuit setup.  The two circuits are probably not exactly identical. Perhaps the two waves generated might be just enough off to generate the big boy I'm after.  I don't think that this will look pretty on the scope but the LEDs don't care.  The bad boy waves that I have seen at sea are ugly looking things but very powerful.

Hi lidmotor. Thanks for reply. I think now we can switching to 2n2222 or mpsa06 transistor with this method. Because 2n2222 at 12 volt the output like the bd243c transistor at 24 volt. I don't have an oscilloscope or spectrum analyzer to looking the frequency :(

Sorry for bad English.
