Another interesting study on the effects of ELF (extremely low freq) EM radiation .
http://www.mas.bg.ac.rs/istrazivanje...c%2093-103.pdf

If you do not want to read all of it skip to the end.
Perhaps for us the point may be that we do not have to get exactly 7.83hz to get desired effects.

I have always assumed this much. As the ionosphere varies in height, a precise frequency seems unnecessary although making it user adjustable is probably important.

Not sure if i buy any of this New Age mumbo-jumbo anyway and suspect that the effect is entirely electrical. One of the reviews contains an interesting supporting experiment. The reviewer made recordings with the generator being both on and off and subsequently they sounded different.

Default Amplifying local Schumann resonance

The ideal position might to synchronize with local Schumann resonance and made an amplification.

Is there any suggestion for a schematic?

Eric your suggestion makes sense but this would imply that you then need a receiver circuit to catch on and then lock onto the Schumann resonance. So how do you do that? You would also want the two resonances to be in phase I think.

Interesting site

Allen I just dug up some small step down transformers which have two 120 volt primary windings and are EI style will these work ok as a radiating antenna?

I just found this site which has two basic and inexpensive units for sale.
KRT: ELF 7.8 Hz

Default CD player used as generator - step 2

I made some changes on my CD player used as a Schumann resonator to keep 2V RMS on output with 600 ohm load.
One output is directly wired to the output AOP (3V DC output), the other integrates a 100uF electrolytic capacitor to suppress the DC value. With 600 ohm load the output is about 3% lower with serial output capacitor.

I start CD player as Schumann resonator and perform a listening test comparison (listening audio system with various configuration on Schumann resonator). The direct output (including DC value) gives better results. After this first test, I made standards optimizations on the Schumann CD player by managing vibration.... Each improvements, improves rendering on listening audio system. It seems that more Schumann resonance steady and clean better results are.

It match with comparing test made by analog_sa on comparing power transformer on Schumann resonator.

Default sign wave generator...

the Healing Earth generator produces sine wave output at 7.83 Hz with a variable output. See link below.
