@nul-points .You beat me to it on the subject of parasitic oscillation . If you refer back to the thread I started , called" Overunity Parasitic Oscillator?" you will see that most of the designs mention use abrupt parameter changing by switching . If this device is using parametric oscillation . it is closer to an ideal design , in that the parameter in question , inductance , is changed in a "dynamic" or sinewave like manner .Hope that makes sense .

yes - i just looked back to try & find a scope trace which i though might be relevant to this & it seems to have been removed 

the conversion you guys were discussing involved two frequencies 'f' & '2f' which doesn't on the face of it seem immediately applicable here - but that's not to say that a parameter change on a regular basis within a pulse event may not exhibit something of the same effects

let's see if this strikes a chord for whatever Ben was remembering?

thanks

sorry to find that you removed your post

i don't think it's a case of 'no interest' - more a question of a large number of people getting dragged into bl..dy stupid wild-goose chases

would you reconsider your edit & repost for us please?

maybe today we can regain focus on the issues at hand

thanks

Sorry if that bring some noise to the discussion, but I don't understand why the scope shot Romero posted is slowly translating down through time ? is it supposed to be a voltage scope ? what does that mean ?

@tanakat
I have seen this type of scope display many times.
If you set the scope to a much lower freq. you will often see a low freq. sign wave,
that's being modulated by the higher freq.
So this means there are 2 freq. at play here. 
Maybe Romero can give us a much lower freq. scope shot
so we can get a look at that much lower wave as well. 
At a different time you will see the signal slowly translating upwards at the same rate.

... or his trace rotation is off.
