Should be aware the planet is a flattened ovoid. N/S circumference is smaller than equatorial. Difference in diameter is about 50 miles, IIRC.

ahh you beat me to it, the Earth is mostly flat! NOT Spherical.
Give me a break. It's almost perfectly spherical. Which is why you can calculate the wavelength of a Schumann frequency based on the radius of the Earth. Duh! Ever see the view of the Earth from space? It's a sphere!

50 miles would show up in the second decimal place of the Schumann frequency and even then only by about one or two hundredths. That's the worst case. Big deal. The diameter of the earth at the equator is 7,926.41 miles (12,756.32 kilometers). But, if you measure the earth through the poles the diameter is a bit shorter - 7,901 miles (12,715.43 km). A difference of only .003. Hel-loo!More to the point even if there were some small difference in frequency say between Alaska and Australia, for a stationary person anywhere on the Earth the frequency would be stable. Nobody said there is absolutely zero variation, it's just that it's negligible. Wake up and smell the coffee.

It's NOT an Oblate spheroid? That's what I always thought!Yes, of course. This fact was apparently known to even the Ancient Egyptians. The length of degree varies as a function of Latitude. There exists a regular additive series which expresses this change.
We can talk about Egyptian Cubits, if you like, or even the ancient measure of Stadium, which is apparently 185 meters or 1/10 minute of arc.Modern 'shape of Earth' stuff revolves around whose 'spheroid' you use as reference.
When I talk about the shape of the Ionosphere, it is NOT conformal to the shape of the Earth, but rather responds to the Solar Wind, as well. At a particular point on Earth, the Schumann Resonance measure will change as a function of time of day and solar orientation.

Also length of a waveguide is determined by the length if the center line between two surfaces
'start' of ionosphere varies by who you read. I don't even know hi / lo numbers but for purposes of this discussion, doesn't make much difference.
What DOES matter, and is unknowable, is the long-term history of the resonance frequency. Apparently long enough that mammals are responsive to it, though variations in Alpha Wave frequency MAY indicate other factors at play or even a change in frequency over long time periods.
I'm searching for an EASY to build Schumann Generator. I've seen one using a 555 but the coil / inductor part of the discussion was lacking.
Any tips in this regard are appreciated. This is one avenue which seems worth exploring.
Too much is never enough
The other issue ignored thus far is that the Schumann frequency is the lowest base line frequency. The planet's surface does not follow Euclidean geometry. An electrical Schumann occurrence will not necessarily follow the longest path (across the center line of the planet), but will go in all directions, hence we will have many higher frequencies with the shorter wavelengths.
Yes, and they also do NOT appear to be 'harmonically' related to the 'fundamental'.

You must be referring to the partials. You guys can't even Google right. Lol"In the normal mode descriptions of Schumann resonances, the fundamental mode is a standing wave in the Earth-ionosphere cavity with a wavelength equal to the circumference of the Earth. This lowest-frequency (and highest-intensity) mode of the Schumann resonance occurs at a frequency of approximately 7.83 Hz, but this frequency can vary slightly from a variety of factors, such as solar-induced perturbations to the ionosphere, which comprises the upper wall of the closed cavity.[citation needed] The higher resonance modes are spaced at approximately 6.5 Hz intervals,[citation needed] a characteristic attributed to the atmosphere's spherical geometry. The peaks exhibit a spectral width of approximately 20% on account of the damping of the respective modes in the dissipative cavity. The 8th partial lies at approximately 60 Hz.[citation needed]"

"In normal mode descriptions", ....
It doesn't say that it is the only mode. The fundamental mode is always the lowest frequency, QED.
The passage quoted totally ignores other possible pathways for the source of the Schumann disturbances.
Oh Yeah, 60 hz as the 8th partial is certainly way beyond the percentages you were quoting.
What are you referring to? If you believe there are fundamental modes other than 7.83 Hz by all means provide evidence. Just repeating the same thing over and over again doesn't really do much good. You can even cut and paste if you prefer, you know, if you don't know off the top of your head. Of there are other fundamental frequencies why does the Acoustic Revive device utilize ONLY 7.83 Hz? Not only that but the new RR-888 device actually generates the 7.83 Hz frequency MORE ACCURATELY.
