Our FM channel is restricted. This is a microwave frequency band that is very convenient for communication, mainly concentrated in the range of 87 to 108 MHz. These frequency bands cannot be occupied privately without approval.
There are many regulations on radio management. For example, the 1400-1427 MHz frequency band is an astronomical observation band stipulated by international conventions, and no one in the world can occupy it. In other words, when you observe signals in this frequency band in space, the entire earth is quiet. If you observe other frequency bands, the signal sources are so numerous that they explode.
The same is true for the management of FM radio waves.
Why can illegal radio stations occupy the frequency bands of official radio stations?
Mainly more power!
If there is a black radio station installed upstairs in your house, then its radiation frequency in the vicinity will be more than a hundred times that of everyday radio radiation.
With such a large level of radiation in a small area, it is reasonable to seize the official channels nearby.
Bai Song has been looking for it on the radio several times every night after so many days, and today I finally met it for the second time!
Bai Song agrees with the statement in Capital that sufficient profits can lead to crime. As long as there are still people who fall for it, this chain of crime will not disappear completely due to crackdowns, and there will always be a moment when it will revive.
It is almost impossible to completely eliminate crime. We can only rely on stricter laws and higher crime-solving capabilities to suppress crime, and to make everyone more aware of crime prevention...it is really difficult.
The public security department has been doing this work, but it has not achieved much results. Some people send money to the scammers, and when the police try to stop them, they will fight with the police just to transfer the money...
Bai Song searches these channels every day. Basically, he knows exactly what programs and songs these channels should broadcast during this time period, as well as the names of the hosts.
But, today this is not right.
Today it has become an expert forum column.
Basically, the coverage area of illegal radio stations is not very large, and they mainly target residential areas. Moreover, most people cannot tell that they are illegal radio stations because of the content they broadcast.
Normal channels also have these expert opinions and health guide columns. Most people will just switch to the next channel after hearing these, and no one will think much about it.
But Bai Song can.
If he remembered correctly, the current time on this channel should be the time for crosstalk.
In order to confirm this matter, Bai Song thought about it, called Liu Shuyuan and explained the situation.
"Wait a minute, Captain Bai, I'll see if there's a radio at home." Liu Shuyuan knew about this matter. In fact, he was one of the few people in the Economic Investigation Corps who knew the truth about Bai Song's car accident. After all, the family was... The superiors would definitely know about this kind of thing.
After a few minutes, Liu Shuyuan said to Bai Song, "I turned on this channel and it's Lao Guo's crosstalk."
"Okay, I got it." Bai Song expressed his understanding and hung up after chatting with Liu Shuyuan for a few words.
Now it is confirmed that this frequency band is indeed a black radio station.
In other words, someone has set up a black radio station nearby.
It is not easy to clean up this thing. It is not something that can be solved by one person. Even the branch level may not have enough useful equipment. The last time we cleaned it up, the branch contacted the Radio Committee and other relevant departments to look for it together.
Bai Song decided to listen to what the broadcast was about first.
A familiar scene.
Patients called the hotline and experts gave lectures.
The first two were patients with severe liver disease. They were both weak old ladies. Just by listening to their voices, you could tell they were about to die. They then said their conditions were very serious.
The old professor was very responsible and told the two old ladies two safe plans. He also told them that in this case, they should go to Jiuhe District Central Hospital and other professional liver disease designated hospitals for examination and treatment.
When Bai Song heard this, he wondered, is this a serious lecture?
Jiuhe District Central Hospital is indeed a well-known large hospital in Tianhua City that specializes in liver, gallbladder and stomach diseases.
After explaining several classic cases, even Bai Song, a layman, believed that this expert was very capable!
If Bai Song hadn't known there must be something wrong here, he would have almost believed it! It has to be said that nowadays scammers are spending a lot of money. Although this "old expert" is not an expert, it is definitely enough to fool some non-professionals.
Problems arose with the next few.
Some people's conditions are not very serious, they just have severe fatty liver, alcoholic liver and other conditions. The expert introduced several special-effect medicines. These medicines are very effective. They are all made of traditional Chinese medicine, are non-toxic, harmless and have no side effects. You can buy them directly by calling.
I have to say that these bastards have made great contributions to the current state of Chinese medicine being slandered.
After these calls, I received a thank-you call.
Several old ladies and uncles are really showing off their acting skills! At this moment, their acting skills are so good that they can beat some big-name stars that we dare not offend...
Basically, my physical condition was getting worse and worse, and I couldn't even walk. Now after taking a few doses of medicine, I'm basically fine again. Everything works well. In short, I feel very healthy. I'm so grateful!
At this moment, this "doctor" is basically not a doctor but a god.
Then there was another wave of promotions and purchase restrictions.
The program lasted for about 40 minutes. Bai Song wanted to hear what the next program was, but unexpectedly it switched to the normal channel.
It was certain that this den could not be destroyed today, but Bai Song did not want them to make any dirty money, so he called Liu Shuyuan and gave him the contact information left by the gang.
He believed that Liu Shuyuan must have a way to prevent this phone number from receiving any calls today, and to follow the clues to find out the cause. As for why this matter was given to Liu Shuyuan, Bai Song had his own ideas.
Then, Bai Song really listened to the crosstalk for a while. After more than half an hour, he heard it again in this frequency band, but it was repeated content.
No matter how patient Bai Song was, he couldn't listen to it a second time, so he turned off the radio and went to bed early.
This discovery made Bai Song very excited. He absolutely believed that this radio broadcast must be related to Tian Huan.
Criminals don't have any good intentions. It is impossible for them to do something like "you occupy this place and I leave". Only a few gangsters can do this.
The last time I followed the clues to catch the melon, it appeared several months later, so there is more or less a connection.
Thinking of this, Bai Song called the Qin Detachment to report the situation.
As a police leader, one basically has to keep his phone open 24 hours a day. After Captain Qin received Bai Song's call, he paid close attention and listened carefully to what Bai Song had to say.
