Confirmation of OU devices and claims

[AlienGrey]

Tinsel, if it's any help Donald Smith's original device he was selling, I've seen that device he was selling years ago the original 2 coils and an oscillator it was a Royer OSC assembly.

'Anyone' or his mate 'Someone' or 'Someone else' can make there own.

3) Does the the coupling factors or total energy transfer  be different  in this case maybe because we use a transmission (coupling) from
the coil part in a series resonance circuit (gen.)  to a parallel resonance circuit

  compared with (common radio)  parallel resonance circuit coupled to a parallel resonance circuit(s) ??

My guess is that they are equivalent

Regards Arne

You are correct, they are essentially equivalent. Because of the low output impedance of the signal generator current is basically injected into (by being in series with) the parallel resonant primary circuit.

In common radio tuning circuit, the parallel resonant circuit would provide an impedance match to the antenna and ground which uses to advantage the high impedance at resonance.

Instead of a gate gate driver it's possible to use an impedance transformer
I see some impedance mismatch at the secondary side too
see my suggestion

Heh... at that frequency you are most probably operating in a pure EM mode, so you don't have to worry about "real HV". You may find that you can achieve "supernova mode" close coupling that does not result in a 1/r2 falloff with distance (to a certain limit.) Your receivers seem to be essentially the same as used in my system. The main difference is that I use coils of much lower inductance (and hence less power-wasting in ohmic resistance) and autoresonating drivers, in this case a Royer oscillator:

Hi TK,

yes i remember your experiments and the supernova mode.
Did you ever find out for sure what it caused?  (filament resonance?).

Arne,    you draw a parallel circuit, but i am using a series resonance setup for both RX and TX.
