Do you have access to a scope? it would be interesting to know what the wave form looked like at the coil with and without the small amp that you used. I am curious to know if there is any deformation of the wave when the oscillator is connected directly to the coil, if so does the distortion go away when you insert the amp between the oscillator and the coil?

Here's my question: how come all of the people associated with the "scalar wave" thing seemed to be named Moray? Is it a resonance?

Here is a picture of my test setup....
Probably the problem is with your cables.Try with an audiophile pair

Sorry, no scope.

The coil is in the trash now anyway. I'm feeling a bit better today and it's time for some spring cleaning.

What ever happened to that KBK fella? He used to be all over topics like this.

Believe it or not one of the units i've seen offers a silver coil as an upgrade.

I can see the logic of that.

Hello Moray,

Did you have time to perform your test? (comparing scalar and non scalar inductor). The result might be interesting.

No not yet I have been making flat bifilar coils and replacing the stock units in my friends units. These coils are simply larger than the factory bifilar coils so they result in an increase in radiation. I will be making a cylindrical coil to compare to the bifilar coil. Will report back as soon as I can wind a coil and install it into my friends unit.
