Gyula---Thanks for the analysis of my last video showing the one wire transmission setup.   Your 'mutual induction' explanation regarding the coils was very interesting. Those coils sure are having a conversation about something and telling that light at the end of the string to-- HEY LIGHT UP.  I'm glad that you also noticed that the DC - DC voltage booster was being effected by the whole thing.  Fascinating stuff.  Thanks.

Hi Lidmotor,
I need to make an addition to my post above:  it is inductive coupling which also happening between the two resonant coils and they 'mutually' detune each other, the closer they are placed to each other.  This also needs considering and can be corrected by retuning them.

I went back to the basic circuit like erfandl (12.5V battery, 1K resistor, 200K trimmer pot, 22pF C/E cap,
100nF coupling cap), so no tank circuit (toroid / var cap) and measured the input current and the output
signal to the L3 /ledstrip combo.

No leds where lighting.

Hi Itsu,
Very useful, thank you. 

I think Erfandl uses a 1000 uH choke coil in the collector and not a 1 kOhm resistor any more.

This involves a much higher than 1 kOhm, mainly inductive and increasing impedance for the collector current and its harmonics.

Hi Itsu,

I may have sounded a bit unpolite by mentioning quickly the choke coil in the collector while you used the 1 k resistor, sorry for this. I only wanted to indicate the current decrease with the increasing number of paralleled xtals would be more pronounced when a choke coil is in the collector, a resistor limits both the AC and DC currents while a coil limits mainly the AC current.
Anyway, it remains to be figured out why the input DC current reduces and the output RF power increases when the number of xtals is increased in this oscillator.
