Hi ION
Yeah i could see where EM and yourself were pointing with the mixer, it is very unlikely i am clever enough to get that working so will let you guys carry on your great work.
Thanks for the interest in my circuit.
All the circuits are in my bench, for the above video link the setup is relatively simple.
Here's a brief discovery path.
I built a nS digital Monostable capable of nS pulse delay and nS pulse width control, when 2 of these are fed from a single pulse source one module can be swept on the delay thus phase delaying one channel by 0-255nS, width also has a setting of 0-255nS although after fet stages minimum is about 60nS, I use a micro board to automate the thumb switch increment for phase scan.
Circuit of Digital Mono Board
http://www.overunityresearch.com/index.php?topic=217.0This led to the discovery of a very sharp pulse appearing using both channels to drive either a bifilar or connecting together to drive one coil, i have loads of videos of this, when one coil was driven by both fet channels every now and then a burst of RF would be released at certain phase delays which caused my electronics to become unstable, this caused random firing of the fet stages, during this random firing of sharp pulses i heard explosion noises from a 22 turn piece of wire wound on a wooden former, i could also hear white noise from the coil.
The Pulse with videos

I heard these explosions when i first started TPU research by mixing Fundamental, 2nd and 3rd harmonics in a coil wound on a ferrite ring, the explosion noises were weak and coming from the core. Fundamental Freq was about 35kHz
I then decided to inject white noise into each channel of the digital mono. it occurred to me that SM's discovery path was probably to inject white-noise into his bifilar speaker coil, the digital mono was only really producing narrow pulses i didn't need to use the phase delay for this, with the white-noise generators i could now produce the explosions by driving bifilar coils, before with the re triggering i could only get it using a monofilar drive coil.
White Noise Module
http://www.overunityresearch.com/index.php?topic=273.0With both channels being driven by white-noise generators the video was taken of the resulting crackling noise from the single core coax which had the bifilar wound axially for the coax length.
Note a 20 Ohm load resistor was across the 1 loop of coax inner wire and was scoped to produce the video
