New signal between 420 and 470 MHz

We first detected this signal in Oarsoaldea, at the foot of Jaizkibel, and the signal did not come from Jaizkibel, but from Donostia. Some days with very high values, others none at all. Recently, we have not detected any moments without signal, and the distribution is very different in terms of values, measured throughout the peninsula or measured in a single town. It is also possible that it is of satellite origin.

For now, we have not found a clear source. In a house where the signal enters through a window, when there are other frequencies, if you place a person between the window and the meter, the signal decreases, because the person screens and absorbs this signal, for example with the lowest mobile telephony frequencies, GSM900, in the 900 MHz range, or 4G at 800 MHz and 5G at 700 MHz. In a house in Renteria, an electrosensitive person's screen made of aluminum panels, instead of shielding, was used to repeat the signal, greatly increasing the radiation inside the house.

In places with little pollution from antennas, it is often the dominant signal, and it increases when the meter is pointed at cars. In an area of Irun, there are values of more than 1,000 µW/m², even inside houses. With these values, when using mobile telephony, we usually notice the radiation in our ears or head, in a much more unpleasant way than with this signal. We have no proof of its harmfulness. Its noise is an apparently constant "prrrrrr". We still know little about this signal, although according to some scientific research data, one of its uses could be to affect the human brain, a frequency of 450 MHz has been used as a signal to affect brain frequencies, and, curiously, graphene increases the power of a signal of around 6 GHz with a bandwidth of 450 MHz. We will continue to investigate.
