January 2023, the capital of country F, Xiangmo City
The General Security Bureau of Country F is the main intelligence agency of Country F, which is equivalent to the Overseas Intelligence Agency of Liang Country.
Kanina Dinai is the director of the network communications department of the General Administration, which connects the military's military satellites and long-wave stations that communicate with submarines.
Because of work needs, I also have contact with space experts from country F at the European Space Agency (ESA).
Canina Diné's age is an absolute taboo, but she has been known as Miss Diné in the General Administration for at least 20 years.
Miss Dinai is a typical egalitarian modern white-collar worker in Country F, who spares no effort in work, vacations, and fitness.
She maintains a good figure, her complexion is a healthy wheat color, and she dresses smartly. Even if she changes her style at work, a skirt suit is always the standard.
At three o'clock in the afternoon, two old friends of Miss Dinai hurried to Xiangmo City as scheduled, Professor Louis from Sirule University and Lieutenant Colonel Wilford from Changbo Station in Lu Zhongcheng.
The very low-frequency long-wave station responsible for communicating with submarines is located in Luzhongcheng in the center of country F.
The long-wave radio antenna system consists of 13 cable antenna masts. The central antenna mast is the highest in the world at 357 meters; the inner ring of 6 antenna masts is 310 meters; the outer ring of 6 antenna masts is also 270 meters.
Country F has four main submarines. It is of course ideal to use extremely low frequency communications. However, extremely low frequency long-wave stations require hundreds of square kilometers of underground antenna networks and dozens of kilometers of above-ground antenna facilities. The maintenance cost is extremely high. When a war actually starts, And it is extremely easy to be destroyed by the enemy.
Even in a country as wealthy as Liangguo, its only extremely low-frequency long-wave station was closed in 2004.
Public intelligence shows that in addition to Xiongguo and Tuoguo, Liangguo, F and several other major countries communicate with submarines through very low frequency long-wave stations.
Even for very low frequency stations, the technical requirements are very high and failures occur frequently. Technical expert Lieutenant Colonel Wilford is responsible for daily maintenance and repair work, and he is also extremely busy.
After Lieutenant Colonel Wilford praised the coffee and warm muffins in Miss Dinay's office, he entered the topic and said:
"Ms. Dinai, you know that our long-wave station has been debugged while in use. Yesterday, we accidentally received a strange signal of 3 kilohertz during the FM exercise."
"Wilford, you already told me on the phone. Please tell me and Professor Louis the details." Miss Dinai said.
"The signal source has been ruled out from the ground, but from space. If the signal source is a natural celestial body, it falls within the scope of our astronomical research." Professor Louis said.
"It must come from space, but the signal source should be in low-Earth orbit. The signal lasted for several minutes. We judged that it should come from man-made celestial bodies." Lieutenant Colonel Wilford took a sip of coffee and continued:
"But it's not like the radio waves used for satellite communications. The power of this signal is much greater than that of radio waves, and strangely it can be received in the entire very low frequency band."
"What does it mean that the entire VLF band can be received? Only natural source radiation can have such an effect. There are only artificial satellites in low-Earth orbit, so there can be no natural sources." Professor Louis asked puzzledly.
"This is exactly what I don't understand. The wave I received seems to be in the whole band, and the lower the frequency, the stronger the radiation intensity. This means that the peak frequency of this radiation wave is lower than the very low frequency band, and it is likely to be extremely Low frequency. The lowest frequency limit that my antenna can receive is 3 kilohertz." Lieutenant Colonel Wilford explained.
Professor Louis believes that there cannot be a natural source with such strong radiation power in low-Earth orbit.
The radio contact frequency of any country's satellite is a fixed frequency. It is not necessary and impossible to send and receive radio waves in the entire band.
Mademoiselle Dinay seemed to understand why Wilford reported this matter to her, and asked:
"Wilford, are you worried that a certain country is doing some kind of experiment that we don't know about, and you highly suspect that this experiment is related to military weapons?"
Wilford seemed to have met a confidant, nodding his head in approval of Miss Dinay's judgment.
Professor Louis disagreed. He was still struggling with the issue of natural sources. He said:
"Low-Earth orbit is hundreds to tens of thousands of kilometers above our heads. It is very cold there, with an ambient temperature of only about 3 Kelvin. A natural object that can emit such intense radiation must be a big fireball, but in that case, telescopes around the world will see it. Arrive." The professor continued:
"Even if it is a high-heat object that is not seen by an observer, its peak frequency cannot be extremely low frequency. I can't think of how low frequencies can be weaponized!"
This speaks to the expertise of Miss Dinay, an intelligence expert. She smiled mysteriously and said:
"My dear professor, there are indeed low-frequency weapons. Not only that, they have been used by the former Heroes United Nations."
There was an unsolved case in the last century known as the "Ninsk Signal".
It is said that in the 1960s, at an academic conference in Xiangmo City, former Xiong United Nations scientists proposed that microwaves and radiation with longer wavelengths would cause damage to the human body, especially the blood circulation and the heart and brain systems.
Liangguo's academic authorities present firmly denied it, saying that it was nonsense to claim that low-frequency radiation would cause harm to the human body.
After the theory of the former hero allied scientist was rejected by the authorities, it gained the attention of the intelligence agency BHB.
The latter set up a high-power microwave transmitting antenna on the roof of a building 100 meters away from the Liang Dynasty's embassy in Ninsk, and directed microwaves towards the embassy.
Microwave refers to electromagnetic waves with a frequency of 300M Hz to 300G Hz. It is the abbreviation of a limited frequency band in radio waves, that is, electromagnetic waves with a wavelength between 1 meter and 1 mm. It is a collective name for decimeter waves, centimeter waves, and millimeter waves.
Modern microwave weapons irradiate targets with extremely high intensity, interfering with or damaging the electronic components of the target equipment, rendering it ineffective.
In addition, high-power microwave weapons can destroy the communication link of the drone, affecting its onboard detection equipment and data transmission and processing, or even malfunctioning and causing a crash.
There are many types of microwave weapons. In modern military equipment with electronic warfare as the core, microwave weapons have long become an indispensable standard conventional weapon.
Evidence shows that in addition to microwaves, the former Allied Powers also emitted lower-frequency radiation waves to the Liang country’s embassy.
Years later, people who had been working at the embassy for a long time developed symptoms such as heart palpitations, headaches, and nausea. In 1975, an ambassador from Liang who had lived here for a long time died of leukemia.
A survey report published in 2019 showed that the cancer incidence rate of Chinese officials who worked in the embassy in Ninsk before 1976 was much higher than that of colleagues in other embassies in Eastern Europe.
"Obviously, the very low frequency signal received by Wilford is not a microwave. Whether ultra-long wavelength radiation can also be weaponized is a question that needs to be studied." Miss Dinai concluded, and then said:
"But more importantly now, after excluding natural sources in low-Earth orbit, we need to know what kind of radiation it is, and what kind of man-made spacecraft was launched by which country?"
Lieutenant Colonel Wilford fully agreed with Miss Dinay's opinion, but he said to Professor Louis in confusion:
"Are you saying that you believe the radiation comes neither from high-energy natural sources nor from known spacecraft?"
The professor nodded helplessly in approval.
Miss Dinai asked if there were any other clues. The professor was reminded and said paradoxically: "The Jade Khanate launched a new type of spacecraft a few months ago, called an orbital maneuvering vehicle. I wonder if it has something to do with it?"
"I noticed that you are talking about the commonly known space tugboat!" Lieutenant Colonel Wilford seemed to see hope and suggested:
"We can't figure out the situation. Should we report this strange signal to the Liang Dynasty? Sharing intelligence may be more helpful in finding out the truth."
Mademoiselle Dinay shrugged her shoulders and said:
"Report to Liangguo? When have they done this to us?"
