The Americans have learned to quietly scan all existing radio frequencies.

The US military has learned to scan all existing radio frequencies, which makes it possible to obtain, including classified information, including the radio frequency range used by the Russian military. At the moment, it is known that we are talking about a frequency range from 0 to 100 gigahertz, which creates a threat.

“The experiments of the US military showed that they created a quantum receiver capable of picking up signals from the entire range of radio frequencies. Scientists from the Army Research Laboratory have developed a quantum detector capable of detecting signals from the entire spectrum of radio waves with just one antenna. Conventional devices cannot recognize such a wide range of radiation unless they are equipped with many antennas and amplifiers. In the work, scientists quantitatively evaluated the sensitivity of the sensor to the effects of oscillating electric fields. The field oscillation frequency that the receiver successfully registers ranges from 0 to 100 gigahertz. Such results cannot be achieved using devices based on electro-optical crystals or passive electronics with a dipole antenna. ”- сообщает Informational publication "Popular Mechanics".

Given the capabilities of the experimental setup, experts do not exclude that with its help it is also possible to carry out additional substitution of radio signals, which in turn allows not only to intercept information, but also send it by radio frequency.
