signals coming from Marconi antenna: a big "T" 11 m high
with 30m long top hat.

Here below the first LIVE
spectrogram, updated 30 minutes.
Marconi Antenna + Geophone
Amplitude scale: two channels listed below.
Picture, every 30 minutes, shows last
8 hours. All date and times are in UTC.
Electric filed multistrip daily
representation, useful for comparing anomalies from day
Scroll time 110 sec, updated every 30
Geophone Multistrip hourly
representation, useful for local seismic events
Scroll time 4.6 sec, updated every 60
Here below the same data elaborated as plotting traces. The picture shows the last 30 hours, and values are detected every 150 s.
Picture, updated every 30 minutes. Four traces are reported:
Electric field coming from Marconi antenna: two short portions in 8.2 and 6.4 kHz band at very high frequency resolution, for testing transmission monitoring of radio experimenters.
It shows last month activity.
Frequency resolution 50 µHz, spectrogram scroll time 1
Panoramic view captured from my garden, and a couple of Induction coils, orthogonally placed, inspected by a hen.
ULF magnetic field
Spectrum scale: magnetic components
of the spectrogram below with long term average curve
(red) and last waterfall line.
FFT resolution 10,5 mHz, scroll time 40 seconds. Schumann resonances are almost always visible: when not covered by local noise coming from 380 kV high power line. Also the cars, passing 25 m away from the sensor, leave their trace in the area below 10 Hz. The coil is simply connected to the LINE input of a Realtek 97 audio card. Picture updated every 30 minutes. The spectrogram part below, 0,1 to 4 Hz, it is good for the PC1 detection.
Another representation from the same system:
Induction coil multistrip
spectrogram, for shorter time event representation.
Magnetic field received by induction coil. FFT with 168
mHz resolution, scroll time 4.5 sec. More than 4
hours are showed. Picture updated every 30 minutes.
Multistrip daily representation,
useful for comparing anomalies from day to day:
Scroll time 110 sec, 7 mHz resolution, updated every 30 minutes.
