CSP VLF MONITORING STATION
Live data from Pontese dew (TO), NW Italy, South Europe
Maintained by CSP Team
This monitoring station participated to OPERA2015 project (http://www.vlf.it/opera_2015/opera_2015.html)
This on line observatory makes available a couple of sensitive VLF receivers, installed in a low-noise location. This provides an ideal condition to listen to VLF signals directly from your home, and to make an high quality radio seismic monitoring. Pontese is 2217m dew, over Teleccio dam in Orco and Soana Valley, inside Gran Paradiso national park. To see on google map the site position click here.

A meteo station is placed here: http://wipie.csp.it/vos/mappa/mappa.php?ID_postazione=26#
and the webcam can be reach directly here: http://ham.radio.it/pontese.xspf  (using VNC player)


Antennas and Audio Stream

Two receiving system are placed there:

  • The electric field comes by 2 meters floating electric field antenna, with an ADA low noise receiver.
  • The magnetic component comes from a 1m squared loop, 24 turns of AWG12 copper wire, with a low noise preamplifier. The circuit is similar to the EasyLoop but with an AD797 operational amplifier.
Plain signal, as they comes from the antennas.

The entire VLF activity is stored and archieved in MP3 files for free download.

Observatory data 1

Daily multistrip representation: electric field spectrogram on top and the magnetic field on bottom.

The graph is updated every 15 minutes.

Observatory data 2

Low frequency activity, from 1 to 110 Hz: view on the last eight hours.
On the top the electric field spectrogram, on the bottom the magnetic one.

The picture is updated every hour.

Observatory data 3

Broad band frequency activity, from 1 to 16000 Hz: view on the last eight hours.
On the top the electric field spectrogram, on the bottom the magnetic one.

The picture is updated every hour.


System four: 9 kHz band

Monitoring of 9 kHz band. A reception window centered on 8970 Hz, for the monitoring of testing transmission of radio experimenters. Electric field on top, magnetic on the bottom.

It shows last 8 hours activity.
