♂?，，

  Lin's big hall, Lin Changming looked at his son who was fiddling with the radio, still in a state of shock and hadn't come back to himself yet.

  He felt as if he had just dreamed it, the son who was originally called "fool" suddenly became the "electronic genius" in Xu Lao's mouth, and actually designed and made a radio that even Xu Lao couldn't help but marvel at.

  Although Lin Changming didn't know what Xu Lao specifically did, he knew that Xu Lao used to be a university professor and later came down to Heiyan Village due to the times. This was something he learned from his wife's mouth.

  So all along, he has been at ease and encouraged his son to have more contact with Old Xu.

  It seems that both Xu Lao and Sun Lao intend to cultivate their own sons, but Lin Changming has some hidden concerns in his heart.

  Is this good or bad for Xiaohong?

  Lin Changming's original intention was to let his son live a plain and peaceful life in Hei Yan Village, wait until he grew up, find him a wife, honestly farm a few acres of land, and live the life that rural people should have.

  It seems that this path is no longer suitable for him. As Old Xu said, this child has a special talent and needs to be well-cultivated.

  Take Little Hong over there?

  Lin Changming's expression was complex and he couldn't make up his mind.

  Well, let's take it one step at a time.

  Under the disturbance and confusion, Lin Changming chose to avoid it, he is still unable to make a decision for the time being.

  "Son, Dad won't hit you again from now on." Lin Changming said to his son.

  The benefits that the "offering a humble apology" incident brought to Lin Hong were obvious, his old man explicitly told him that from now on, no matter what he did, as long as it wasn't illegal or criminal, he basically wouldn't interfere.

  At first, Lin Hong thought his father was just talking casually, but after experiencing a few things, he found that his father really kept his promise and didn't ask about it. This made him overjoyed, and from then on, he didn't have to do things secretly like a thief, he could openly and honestly do what he liked.

  Another benefit is that Old Xu treats him even better. Not only can he pick and choose from the items in the waste collection station, but he also has free access to the books on the bookshelves at any time.

  Lin Hong's crystal radio performance has reached its limit, and he originally wanted to replace some components to improve its performance. However, he was stopped by Old Xu. He said that the crystal radio had become a work of art, and it would be a pity to dismantle it like that. He suggested that Lin Hong find spare parts and make another one himself.

  This way, Lin Hong was no longer in a hurry. If he really wanted to start making it again, he wouldn't make a crystal radio this time, but instead move on to amateur radios. However, the complexity of amateur radios is many times that of crystal radios, including not only receivers for receiving signals, but also transmitters for sending signals. Lin Hong decided to continue researching before officially starting work.

  Another reason is that amateur radio has high requirements for components, and he temporarily doesn't have suitable ones on hand.

  As the number of people coming to find Old Xu decreased, he himself ran to the county town more and more times. Lin Hong didn't know the specific reason, he asked his master, but the other side let him focus on learning and practicing, don't worry about it blindly.

  Old Xu went to the county town, usually a day's time was not enough to return, and Lin Hong naturally did not want to miss this opportunity. Every time he told his father that he would "help Grandpa Xu keep watch at night", but in fact, he would secretly use his wireless radio.

  Most of the time, Lin Hong just searched for radio stations and listened to other hams' calls, only actively chatting with the other party when he encountered VBB. As time went on, Lin Hong's knowledge of amateur radio also became more and more extensive, eventually surpassing even his little teacher.

  However, Lin Hong did not show this. He knew that VBB was "good at teaching others", and sometimes he clearly knew the answer to a question, but when asked by the other party, he pretended not to know. Then, enthusiastic VBB began to give him detailed explanations. Sometimes, occasionally Lin Hong would ask one or two questions, and VBB might not be able to answer on the spot, but next time they contacted each other, she would definitely supplement the previous question.

  Lin Hong liked this night listening to VBB giving himself a lecture, he liked chatting with VBB, and liked hearing her sweet voice.

  Every time Old Xu was at home, he thought of mustering up the courage to ask for permission to use his wireless radio several times, but every time the words reached his lips, he swallowed them back. He feared that if he were rejected, he would lose the opportunity to secretly use it at night.

  So, during the day, Lin Hong spent all his time in the electronic waste pile of the purchasing station "digging for treasure", preparing to make his own amateur radio, and at night when he was not chatting with VBB, he studied hard related knowledge, striving to quickly produce a finished product as soon as the components were ready.

  However, Lin Hong's secret use of the radio at night was eventually discovered by Old Xu.

  It was on a sunny afternoon when Old Xu and Old Sun were playing chess together again.

  Then a medium-sized van drove directly to the entrance of the scrap collection station, and four people got out of the van, two of whom were wearing police uniforms.

  Lao Sun heard the noise and looked up, delighted. This game of chess was about to be lost to Lao Xu, but the arrival of these people came just in time to help him escape.

  He spread his hands and said, "I'm not going down."

  "I said this guy is so shameless, he's clearly going to lose but still won't give up." Old Xu immediately became displeased.

  "The comrades from the police station have all come to our door, what else can we do?"

  As he spoke, Old Sun nodded his chin towards the doorway.

  Old Xu turned his head and took a look, and indeed the public security had arrived. He could only reluctantly give up at that point.

  "Which one is Comrade Xu Zhi Zhong?"

  One of the younger public security comrades asked.

  "Alright, Comrade Public Security, I am Xu Zhi Zhong. What's the matter?" Old Xu stood up.

  "Is there a wireless radio at home?" The public security comrade's tone was very stern.

  Old Xu nodded calmly: "Yes, is there anything wrong?"

  "What's the problem? The problem is big!" The public security comrade saw that Old Xu seemed to be looking down on him, and his face suddenly sank. He pointed at Old Xu with his hand and said sternly, "You set up a radio station privately and didn't report it to the relevant authorities. I'm telling you, this has the suspicion of colluding with the enemy. If it were several years ago, this would be punishable by death!"

  Lao Sun's face sank upon hearing this, and he immediately stood up, blocking Lao Xu in front of him.

  "Little comrade, how are you talking? Do you understand respect for elders and care for the young?"

  The public security officer's face turned red with anger upon hearing this, and he took a step forward in agitation, as if to take some action, but was restrained by another older public security officer behind him.

  He gave a signal to one of the middle-aged men wearing glasses, then showed an apologetic smile to Old Sun, and pulled the young police officer out of the yard.

  Lao Sun's eyes, which had been gleaming with anticipation, suddenly dimmed, and he thought to himself, "This is really disappointing."

  A middle-aged man wearing glasses looked at the two departing police officers in surprise, then took a step forward and said:

  "Alright, Comrade Xu. I'm a staff member of the Municipal Wireless Monitoring Station, my name is Lu Yue. Sorry about this, our comrade here has a bit of a temper."

  "Young people can be a bit impulsive, it's understandable." Old Xu nodded without comment.

  "It's like this, our surveillance vehicle recently detected that there are often amateur radio signals emitted nearby, and after our detailed location, it was finally confirmed that the signal was sent from here. According to the information we have, no amateur radio license has been obtained. Therefore, whether it is using a radio station to receive or send signals, it is a violation of the Radio Management Regulations."

  Just as Lu Rui was speaking, his other colleagues noticed the strange antenna in the courtyard. Several people walked to the side of the poles and examined them carefully, exchanging their views with each other while examining.

  Old Sun's face didn't change color, but in his heart he felt some surprise.

  Although his wireless station has been set up for a long time, he has never used it to send signals outside, but only to test the antenna's signal reception effect. In theory, the other party should not be able to track it here.

  There is no so-called more advanced technology, even receiving letters can be monitored, because the monitoring equipment used by the domestic wireless monitoring station is still what he participated in designing and developing back then.
