Our FM channel is limited, this is a very convenient communication meter-wave frequency band, mainly concentrated in 87 to 108 megahertz, these frequency bands can not be occupied without permission.

There are a lot of regulations on the management of radio. 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. That is, when you observe the signal in this frequency band in space, the whole earth is quiet, and if you observe other frequency bands, there are so many signal sources that they explode.

The same is true for the management of FM waves.

Why can black radio stations occupy the frequency band of official radio stations?

The main thing is more power!

If there is an installed black radio station in the upper floor of your house, then in the vicinity of it, it will radiate more than a hundred times more than the daily radio radiation.

With such a large level of radiation in a small area, it is reasonable to be able to seize the official channel in the vicinity.

After so many days, Bai Song looked for it on the radio several times every night, and today I finally met it for the second time!

In Das Kapital, Bai Song agrees with the statement that sufficient profits can lead to crime. As long as there will be people who will be fooled, this criminal chain will not completely disappear because of the crackdown, and there will always be a moment of resurgence.

It is almost impossible to completely eradicate crime, and the only way to stop crime is to rely on stricter laws and higher ability to solve crimes, and to raise everyone's awareness of crime prevention... It's really hard.

The public security department has been doing this work, but it has still achieved little success. Some people send money to scammers, and the police go to stop him, and he can fight with the police in order to transfer the money...

Bai Song is looking for these channels every day, basically during this time period, he is familiar with what programs should be played, what songs should be played, and what the host is.

However, today this one is not right.

Today it has become an expert forum column.

The coverage area of black radio stations is basically not very large, and it is mainly aimed at residential areas, and the content broadcast is not heard by ordinary people.

Normal channels also have these expert statements and health guide columns, and ordinary people will only switch to the next channel when they hear this, and no one will think much about it.

But white pine will.

This channel, if he remembers correctly, the current time should be the time to play cross talk.

In order to determine this matter, Bai Song thought about it and called Liu Shuyuan to explain the situation.

"Wait, White Team, I'll find out if there's a radio at home. Liu Shuyuan naturally understands this matter, in fact, he is also one of the few people in the Economic Investigation Corps who knows the truth about Bai Song's car accident. After all, the home is... This kind of thing must be known to the superiors.

After a few minutes, Liu Shuyuan said to Bai Song: "I'm here to open this channel, it's Lao Guo's cross talk." ”

"Okay, I see. Bai Song said that he understood, and hung up after chatting with Liu Shuyuan for a few words.

Now it is confirmed, and now this frequency band is indeed a black radio station.

In other words, there is a black radio station set up in this neighborhood again.

It is not easy to clean up this thing, it is not something that can be solved by one person, and even at the level of the sub-bureau there is not necessarily enough useful equipment, and the last time it was cleaned up, the sub-bureau contacted the radio committee and other relevant departments to find it.

Bai Song decided to listen to what this radio was talking about first.

Familiar bridges.

The patient called the hotline and the expert gave a lecture.

At the beginning, the two were both patients with very serious liver disease, and they were both old ladies with weak energy, and they basically knew that they were about to die when they heard this voice, and then said that their condition was very serious.

The old professor was very responsible, told the two old ladies two safe plans, and 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.

Bai Song listened, is this a serious lecture?

The Central Hospital of Jiuhe District is indeed a famous big hospital in Tianhua City for liver, gallbladder and stomach diseases.

Several classic case explanations made Bai Song, a layman, believe that this expert has a level!

If it weren't for Bai Song knowing that there must be something wrong here, he would almost believe it! I have to say that now the scammers have all paid their money, although this "old expert" cannot be an expert, but it is definitely enough to fool some non-professionals.

The next few are problematic.

Some people are not very serious, just severe fatty liver, alcoholic liver and other conditions, this expert introduced several special drugs, these drugs have a very good effect, are traditional Chinese medicine ingredients, non-toxic, harmless and no side effects, you can buy directly by phone.

I have to say that Chinese medicine has been hacked into what it is now, and these bastards have "contributed greatly".

And after these few calls, I received a thank you call.

A few old ladies and uncles are simply flying acting skills! At this moment, their acting skills are bursting, killing some big-traffic stars that we dare not offend...

Basically, my physical fitness is getting worse and worse, and I can't go to the ground, but now I've taken a few pairs of drugs, and it's basically OK, all kinds of lines, in short, it's a great body, thank you Dade!

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 almost 40 minutes, and Bai Song wanted to hear what the next program was, but he didn't expect to switch to a normal channel.

This den will definitely not be able to be destroyed today, but Bai Song didn't want them to make black money, so he called Liu Shuyuan and gave Liu Shuyuan the contact information left by the gang.

He believes that Liu Shuyuan must have a way to make this phone number not receive a single call today, and he will touch the melon. As for why this matter was given to Liu Shuyuan, Bai Song had his own ideas.

Then, Bai Song really listened to the cross talk for a while, and after more than half an hour, he heard this again in this frequency band, but it was a repetitive content.

Bai Song couldn't listen to it a second time no matter how patient he was, so he turned off the radio and rested early.

This discovery made Bai Song very excited, and he absolutely believed that this radio broadcast must be related to Tian Huan.

Criminals don't have any good intentions, and this kind of thing can't happen to them if you take this place and leave me, unless a very small number of underworld people can do it.

And the last time Shun Teng caught the melon, it has only appeared after a few months, and it is more or less related.

Thinking of this, Bai Song then called the Qin detachment again to report the situation.

As the leader of the police, he basically has to keep the phone open 24 hours a day, and after the Qin detachment received Bai Song's call, he was very concerned and listened carefully to Bai Song's explanation.
