When Lin Hong and the others arrived at the Friendship Hotel, Cook had already been waiting there for a long time.

When he saw Lin Hong take out the drawings of the amplified circuit again, he became more confident in Lin Hong's product. He strongly recommended that Lin Hong integrate the signal amplification function into the original drawings.

The integration was not difficult, and Lin Hong completed the design of the overall drawings almost on the spot.

With nothing to do with him, Mu Simin took over the work and began to talk to Cook in detail.

According to Mu Simin's opinion, it is not only necessary to apply for a patent for this product, but also for this design method and the most basic circuit diagram, so that even if others want to imitate similar products later, they cannot use similar circuit principles, and can only find another way.

Cook couldn't agree more. They quickly reached a series of consensuses and drew up a relevant entrustment agreement, because Lin Hong is still relatively young and does not have the corresponding identity certificate, so his guardian Feng Wan signed it on his behalf.

After getting this done, Cook was anxious to see the final effect of the finished product, so he proposed to go to the amateur radio club in the capital S and let Lin Hong demonstrate it live.

Mu Simin acted as a temporary driver again, and everyone went to the capital to kill.

Xu Wenjing was a little delayed this morning, so when she arrived at the Friendship Hotel, she found that Cook was no longer in the room.

Carefully asked the hotel front desk, and the other party was not very sure about Cook's itinerary, but said that he heard them mention the word "Beijing S".

Xu Wenjing did not hesitate, hurriedly ran to the hotel parking lot, and said to the driver: "Hurry, go to S." ”

Air Force Radar Research Institute.

"Jingle bell—"

As soon as Feng Anguo returned to his office, the phone on his desk rang non-stop.

"Hey, who's that?"

"Second, it's me."

Feng Anguo was stunned: "Big brother? How did you remember to call me? ”

He felt very strange that under normal circumstances, his eldest brother, Feng Anbang, rarely called his office.

A deep voice came from the other end of the phone: "Let me ask you, did Xiao Wan go to Lingnan Province?" ”

Feng Anguo paused for a while, and finally said, "Yes." She went to Lingnan Province a few days ago to attend a conference. ”

"Some people say that when she comes back, she brings back a child, do you know that?"

"Who told you?"

"You don't care about this, I just want to make sure if there's such a thing."

Feng Anguo said helplessly: "Yes." Big brother, after so many years of this, do you still want to be stubborn? Xiaowan is so old now, do you still want to delay her? ”

"I see." The other party was indifferent to his questioning, "You can take the time to come back on the weekend." ”

After saying that, the other party hung up the phone.

Feng Anguo listened to the busy sound in the earpiece, sighed, and hung up the phone with a snap.

Xu Wenjing hurried to the capital S, and after getting out of the car, she went straight to the amateur radio club.

When she was in the car, she thought that there should be only one reason for them to go to S, that is, to test the thing made by Lin Hong.

But when she ran to the door of the club, she saw Chen Xiaoyu, a member of the club, closing the door and locking it.

Chen ...... Chen Xiaoyu, what about them? Xu Wenjing was already tired and panting, she held her stomach and breathed in the air and asked.

"Them?" Chen Xiaoyu was slightly stunned, and then reacted, "Oh, you mean Mr. Cook, right?" You're late, they've been gone for a while. ”

"Wen Jing, do you know, just now they brought a small box, directly connected between the radio station and the antenna, it can filter out most of the noise, you don't need to adjust the frequency to hear it clearly, and after connecting another gadget, the signal that was originally only 36 turned directly into 59, it's amazing......" Chen Xiaoyu said excitedly.

This is simply the artifact of ham, with those two small things, the efficiency of radio transmission and reception will be greatly improved, and the threshold of amateur radio will be greatly reduced, even beginners can easily operate the radio.

Xu Wenjing didn't have the heart to listen to what he said at this time, but she was lost in her heart.

She came all the way, but she didn't expect to be a step too late.

"Do you know where they went?" Xu Wenjing asked reluctantly, "Are they going back, or are they at school?" ”

"This ...... I don't know. Chen Xiaoyu said helplessly, "But a group of leaders of the school are accompanied, so they shouldn't have left yet." ”

Hearing his words, Xu Wenjing immediately ran towards the political and religious office again.

The Political and Educational Office is located on the north side of the campus, and the buildings there are all Western-style, or the old school building built by foreigners when S Middle School was established, but the design is very good, and after the expansion of S Middle School, those buildings have become the school's place to handle government affairs.

Between the place where the amateur radio club is located and the political and religious office, there is a garden called Bichun Garden, with a pond in the center.

Xu Wenjing hurriedly walked through Bichun Garden and ran towards the Political and Educational Office.

However, as soon as she left Bichun Garden, Lin Hong walked in from the other side.

He went to the central pool, looked bored at the few red carp left, and threw a pebble into it from time to time.

Just now, Cook has confirmed the function of his "adaptive signal filter", and Lin Hong merged the circuit of the signal amplifier with the previous circuit on the spot, designed a drawing that integrates signal filtering and amplification functions, and handed it to Cook to apply for a US patent on his behalf.

After this matter was over, at the warm invitation of the school leaders, his mother Feng Wan and Mu Simin both held a symposium in the conference room of the Political and Educational Office.

The main content of the meeting was to let those exchange students from the United States freely choose their Chinese families, and then they will live in the families of their choice for a whole year.

Lin Hong didn't like crowded places, so he found an excuse to come out of the venue, he had seen that this Bichun Garden was relatively quiet, so he walked all the way here.

Looking at the carp swimming in the water, Lin Hong felt a little lonely. He misses home in the countryside a little.

I don't know what happened to my father's car and wood factory business, the business is not good, and he can't make money, but the business is good, and he can't be busy, he has to work overtime every day, I'm not at home, he shouldn't be too lazy to cook, right?

When will Daddy come over?

I don't know how Huang is, I'm not at home, it should be hungry all the time, right?

Hey, I knew I should have fostered it at Master's house. But fortunately, it has known how to go out to find food since it was a child.

……

Lin Hong has never been far away since he was a child, but this time he ran thousands of miles away, and he couldn't help but feel a little homesick in his heart. He still has little affection for this home in the capital because the time is too short.

Well, I'll call Sun Wu later and ask him to come to me to play games, he'll definitely like it.

At this moment, a crisp voice suddenly sounded in his ear:

“xzz！”
