"Rtanj" is a mountain situated in eastern Serbia, approximately 200 km southeast of Belgrade. It belongs to the Serbian Carpathians. Its highest peak is Šiljak (1,565 m), a natural phenomenon of karsts terrain. A widely known traditional product of Rtanj is the "Rtanj tea", made from herbal of winter savory. It is celebrated for its antiseptic and aromatic properties, and is allegedly an aphrodisiac.

According to a legend, the castle of a wizard was situated on the Rtanj Mountain, in which a great treasure was hidden. However, the castle has disappeared over the years - if ever it was there - and now, on the top of the Rtanj's highest peak Šiljak, there is the ruins of a little chapel dedicated to St. George. It was built in 1932 by the wife of a former local miner. Today, the chapel is in ruins, as it was partly destroyed by dynamite, when treasure hunters tried to find the hidden gold...



For some New Age believers, the pyramidal shape of the mountain is due to it containing an alien pyramid emitting mystical energies. Likewise, lot of legends about dragons and fireballs as well as testimony about the excursionists meeting with ball lightning (!) can be heard In the vicinity of Rtanj mountain... A mere sight on the mountain, which is in the form of a three-sided pyramid raised abruptly from the plains, causes admiration. These sharp edges nature is hardly able to create without the help of some "intelligence".

Anyway, the facts are these.

The longest edge of the pyramid, that stretches to the north, is three kilometers long, the southwest is a long a kilometer and a half, while the south-east edge stretches up to 750 meters. So, it is obvious that their mutual relationship is 4: 2: 1, and the same occurs in the difference of a three-sided pyramid ending points altitudes. And yet, Rtanj has slope side identical to that on the pyramid dedicated to the Moon in Mexico, as well as its triangular sides angles that match those on the Cheops pyramid!

For me - as a Nikola Tesla Technology expert - most interesting is the fact that Rtanj attitude is exactly 1565 m - that is a number very familiar with Nikola Tesla most controversial machine: “Magnifying transmitter" from Colorado Springs, and its ability to produce a standing waves i.e. a “Scalar Fields”.

That was a main reason to make the “energy fenomena” measurements with the scientific equipment, according to scientific methods.



Measuring equipment:

1. Teslameter TM 40 [H50Hz,nT]

2. Trifield meter, 100XE [H, mG; E, V/m]

3. The digital multimeter Mastech MS8229 [T, oC; Hum, %; Noi, dBrel]

4. HF-broadband amplifier IB Mraz, "E" - probe: rod antennas, L = 30 cm; "H" - Probe: open coil;

5. PC oscilloscope OWON, VDS1022

6. Notebook MSI, Quad Core, Win 8.1

7. S-meter, Bedini version of Dea / Faretto Detector, IB Mraz, [Sc, Ampl., % Deflection]

8. Experimental life energy meter, Heliognosis model LM3, [[Or, Range, Fine, Coarse, % deflection]


Note 1:  EM spectrum varies slightly, the signals are changeable in amplitude and frequency, except ordinary signals generated by measuring equipment (Inverter/ Oscilloscope switch + sampling rate, etc).The signals that originate from measuring equipment and devices used during measurements were registered before measuring at selected locations. Vrms value registered by equipment no 5 and 6 should be considered as a relative values, considering that the equipment no 4 was used during the measuring. In case of need, the registered values can be recalculated and expressed as absolute.


Measurement Method:

Magneto Telluric (MT) and Audio Magnet Telluric (AMT) methods /ref. 1/



MT and AMT methods /ref. 1/ are a electromagnetic methods that measures variations in the earth's surface electromagnetic fields at different frequencies.

It samples the electric and magnetic fields in the low (IF-Audio-UF) frequency range. Sources of the MT/AMT signals may be either artificial or natural.

Solar energy and lightning cause natural variations in the earth's magnetic field, inducing electric currents (known as telluric currents) under the Earth's surface. Earth currents arise from both natural and man-made sources, including the magma in the earth’s core and the normal distribution and use of electricity. Combined, these phenomena create strong magneto telluric source signals over the ULF/LF frequency spectrum.

MT measurements can investigate depths down to hundreds of kilometers. Greater depth requires lower measuring frequencies, which in turn requires longer recording times. Very deep, very long-period measurements (mid-crust through upper mantle depths), may require recordings of several days to weeks or more to obtain satisfactory data quality. AMT is a higher-frequency magneto telluric technique for shallower investigations. While AMT has less depth penetration than MT, AMT measurements often take only about one hour to perform (but deep AMT measurements during low-signal strength periods may take up to 24 hours) and use smaller and lighter magnetic sensors. 

Magnetic fields in the frequency range of 1 Hz to approximately 20 kHz are part of the audio-magneto telluric (AMT) range. These are parallel to the Earth surface and move towards the Earth's centre. This large frequency band allows for a range of depth penetration from several meters to several kilometers below the Earth's surface. Due to the nature of magneto telluric source, the waves generally fluctuate in amplitude height. Long recording times are needed to ascertain usable reading due to the fluctuations and the low signal strength.

The multidirectional MT sounding, performed on different locations can clearly indicate a different ratio of the electric to magnetic field and theirs phase shifting caused by the different speeds of propagation, pointing in that way to different subsurface areas mechanical, magnetic and electric conductivity, i.e. its anisotropy and in fact - its structure.


Measuring values:

The research include the recording of electromagnetic and mechanical energy spectra, and are performed on magnetotelluric method in the frequency range from extremely low to medium frequencies (25 mHz – 50 kHz) for electric and/or magnetic phenomena.

Measuring of mechanical vibrations covers an area of infrasound, audio and ultrasound range. For these measurements we used the conventional devices numbered as 1. to 6. in the list of measuring equipment.

In addition to these measurements the detection of the presence of scalar fields [10] was performed by "S-meter" (Eq. 7). Investigations of unconventional energy fields, as “Orgone energy” is e.g., was carried out by special alternate energy device (Eq. 8.) that is intended for scientific research into life processes.

Furthermore, at each measuring point control parameters were measured: a) presence and intensity of the "EM smog" caused by power network (50 Hz); strength of the dynamic magnetic (b), dynamic electric (c) fields and radio waves strength (d); temperature (e), humidity (f) and noise (g).

Complete measurement recordings are stored in my database but in this paper we introduce only the most interesting findings just as a illustration of ours analyses and conclusions.




Location 1: "Rtanj, Šiljak, position on the edge of the vertical hole", 09. April 2017, 14.06 h.





Measured values:

H50Hz = 4 nT, H = 0.6 mG, E = 30 V/m, T = 16.4 oC, Hum = 15 %, Noi = - 28 dBrel, Sc = 10,0.5; Or = 100,3,1,100

Note 1: The device for “alternative energy phenomenon’s” measuring (Eq. 8) was reacted a very intensive. This device is calibrated in relative units and therefore is set to "calibrated" sensitivity. Any change (reduction) of sensitivity would reduce possibility of comparing this measurements and measurements performed earlier - at other locations. My impression, for this measuring setup, is that the relative value of “life energy” at this location is several times higher than all so far measured by this apparatus.
