IK1QFK VLF MONITORING STATION Live data from CUMIANA (TO), NW Italy, south Europe

(To see on google map click this link  (44,96° NORTH - 7,42° EAST)
 

System one: LIVE mp3 audio streaming

Audio signals coming from Marconi antenna: a big "T" 11 m high with a double top hat 45 m long.
You can listen the audio streaming live clicking here: http://67.207.143.181/vlf15.m3u
 

The audio streaming server is provided by Paul Nicholson.
See at Paul's page "Live VLF Natural Radio" for others audio stream availables: http://abelian.org/vlf/

Here below the first LIVE spectrogram, updated every hour at xx:01.
It shows the last 8 hours VLF activity, as received by Marconi antenna (electric field).

System two: GEOMAR

Amplitude scale: two channels listed below.

• Channel 1, seismic monitor. Frequency range: 1 to 40 Hz for the top spectrogram. Signals coming from geophone I/O SENSOR Nederland b.v. model SM-4/UB8 (see at http://www.geophone.com/techpapers/SM-4%20Brochure.pdf) 50 dB amplified with a very low noise preamplifier.
• Channel 2, electric field. Frequency range: 1 to 105 Hz for the bottom one. Signals coming from Marconi antenna: a big "T" 11 m high with a double top hat 45 m long (see the first picture in the article http://www.vlf.it/romero/seismic_rdf.htm)

Picture, updated at xx:05 minutes of every hour, shows last 8 hours. All date and times are in UTC.
The scroll time is 20 s, and the frequency resolution 42 mHz.
As the receiving station is placed not too far from an industrial area, sometimes strong tones are detected by geophone sensor, caused by mechanical machine (1 km far from here).

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 at xx:05 minutes of every hour. Four traces are reported:

• Geophone trace , it shows the average and peak signals coming from the geophone sensor, in 1-20 Hz range.
• ULF noise 10 Hz , it shows the medium value between 3 and 30 Hz.
• ELF noise 100 Hz , it shows the medium value between 30 and 300 Hz.
• 2th SR freq. , it shows the frequency of second Schumann resonance (in Hz).

System three: MINIMAL

Amplitude scale: two magnetics components of the RDF spectrogram below.
Spectrogram: radio direction finding colors, obtained with two orthogonal loops EW and NS oriented (see at the article http://www.vlf.it/minimal/minimal.htm and http://www.vlf.it/minimal2/minimal2.html for technical details). Frequency range 1 to 105 Hz. System sensitivity of 0.5 pT @ 10 Hz.

OOS ALM //The system is temporarily out of service

Picture, updated at xx:03 of every hour, shows last 8 hours. All date and times are in UTC.
The scroll time is 20 s, and the frequency resolution 42 mHz.
Magnetic landscape is worse than the electric one: the receiving station, although in a country place,  is placed few km far from an high power line (380 kV !) and next to an industrial area (1 km).
