Magnetic Resonance Devices based on Don Smith Concepts

[stprue]

Hi marco
I have ordered the book Don references to with the charts but it has not arrived yet.

I am slowly getting to the point where i can progress, my main concern so far has been getting my coils to the right dimensions.

I have just powered up using a sig gen and a 200nF cap across my primary, i wanted to see what i would get on an untuned secondary coil.

I have attached 2 FFT shots

I am not yet ready to power this with an NST as it hasn't arrived yet but soon.

Looks great Peter...but how do you keep your work desk so clean

Hi stprue
Simple i only built it last week , rest assured it will be the last time i post a picture of it that clean

As far as I understand Don Smith device is using quarterwave length receiver with a EXECT coil copy of receiver being "untuned" part of L2 wich act as VIRTUAL GROUND for first L2 part. If both L2 parts were tuned you would have a real dipole but since only one part tuned so its seems to be nothing else but as I have said quarterwave length receiver with virtual ground plane.

Quarter wavelength antennas must be grounded to work properly so basicaly such an inductor must be grounded to recreated its missing dipole part image in earths ground. So. We can use earth ground OR we can attach a "MIRROR" coil or "VIRTUAL"  ground to finish up a dipole.

Here is a recent vid I made of a air core TPU.  I'm not sure if you have seen it but it is related to this topic as well.  Let me know what you think!

Thank you for that description Minde, I actually understand this concept much better now!
