31Jan 2021. Prototype Data Acquisition And Procession System; Antenna-building Continued.
21Stated Clear Intention.
Still it's ever-important to understand the chain of processing necessary to get a clear signal, which is translatable into a legitimate Schumann Resonance report detail.
In the following series, we shall be continuing to examine the data acquisition and processing chain necessary in carrying the signal from detector, to an on-line graphic that the public can access, for free.

"A PROTOTYPE DATA ACQUISITION AND PROCESSING
SYSTEM FOR SCHUMANN RESONANCE MEASUREMENTS"
Giorgos Tatsis, Constantinos Votis,
Abstract
In this paper, a cost-effective prototype data acquisition system specifically designed for Schumann resonance measurements and an adequate signal processing method are described in detail.
The implemented system captures the magnetic component of the Schumann resonance signal, using a magnetic antenna, at much higher sampling rates than the Nyquist rate for efficient signal improvement.
In order to obtain the characteristics of the individual resonances of the SR spectrum a new and efficient software was developed.
The processing techniques used in this software are analyzed thoroughly in the following.
Evaluation of system’s performance and operation is realized using preliminary measurements taken in the region of Northwest Greece.

1. Introduction
The space between the earth and the terrestrial ionosphere forms a large electromagnetic waveguide, considering that the earth surface is a conducting sphere as the ionosphere boundary.
It is experimentally proven that the earth-ionosphere waveguide permits the generation of electromagnetic standing waves in the range of extremely low frequencies (ELF), where the wavelength is related to the dimensions of the earth-ionosphere cavity
(Balser & Wagner, 1960; Balser & Wagner, 1962).

We are telling you how to properly read report, and the limitations of these sensors. The nature of this job IS technical, and scientific. I am not operating in a belief bubble in reviewing the machines, and equipment; or otherwise, I would not be able to tell you the readings properly. My job IS to tell you "that's not what the machines are saying".

Cumiana, as part of the CIEN network of detector sites, measures the Electrical component, as this is what accompanies earthquake behaviour.
At the bottom of this post, is an excerpt from the conclusion of C. Fidani in his symposium of the connection with earthquakes, seismicity, and signatures at the VLF, and ELF band of frequencies; based on research at CIEN.
Tomsk, Russia, is a part of the Space Observing System, within the Tomsk State University. This station is a dedicated Schumann Resonance station, which measures the horizontal (quality) up to 40Hertz, and the Vertical (Amplitude) up to 200 deci-Bels pico-electron-Volts.
Tomsk SU has a more "modest instrumentation," as theirs is a site dedicated to only the dedicated spectrum of Schumann Energies; the resonant harmonics of which extend to ~46 Hz, in the horizontal frequency.

The first lesson of understanding the Schumann resonances is "examine your local environment first. Examine the local weather at the antenna-detector state, secondly. Compare the two, thirdly. Your results may vary from what it says in Russia."
