As night falls, so does dinner time. Pen "Fun" Pavilion www.biquge.info

The canteen at the weapons test site sounded the meal call at seven o'clock in the evening.

Hearing this melodious and loud military horn, Ding Chenggong felt really hungry. I looked at my watch, and it was already seven o'clock. This is the end of the day's lessons.

After a simple dinner in the cafeteria, Ding Chenggong took the guard Xiao Xu and rode a Nissan Mitsubishi military three-wheeled motorcycle specially assigned to him by Yang Jingyu to the auditorium of the headquarters.

In the auditorium, the young students who had been specially transferred from various departments to learn radio operation were already sitting upright at the desks that had been arranged.

Each desk was carefully arranged in the style of an electronic console in accordance with Ding Chenggong's requirements in advance. There is also a conspicuous white cardboard box next to the desk.

Inside, there are all the electronic components that can be assembled into a radio transmitter.

Next to each table, a pair of unopened white gauze gloves are also specially placed.

Stopping the motorcycle, he came to the door of the classroom, and through the glass window, Ding Chenggong was pleased to see that it was more than 70 students, under the leadership of the class leader, who were seriously studying the training materials distributed in advance.

Seeing the students concentrating and studying hard, Ding Chenggong couldn't help but think of himself when he was in his third year of high school and wholeheartedly prepared for the college entrance examination.

Touching the scene with a knowing smile, Ding Chenggong gently pushed open the door and walked into the quiet classroom with gentle steps.

"Mr. Ding is here. Stand up, everybody! ”

The squad leader noticed that someone had quietly walked into the classroom, so he raised his head and saw that it was Ding Chenggong, he immediately put down the textbook in his hand, immediately stood up, and shouted loudly: "Everyone stand up and salute the instructor!" ”

At the sound of an order, all the students put down their textbooks in a uniform manner, stood up in unison, and saluted Ding Chenggong with a standardized military salute, and shouted neatly and powerfully: "Hello instructor!" ”

"Hello students!"

Strode to the podium. Ding Chenggong replied with a military salute very solemnly, and said loudly: "Everyone sit down!" ”

As soon as the students sat down neatly, Ding Chenggong said seriously: "Everyone knows that we have won a big victory on the skyscraper, and the team has expanded from the original four or five thousand people to nearly 20,000 people at once!"

As the ranks expand, the task of communication and liaison between the various units will inevitably become a top priority. Therefore, the leaders of the command decided to create a professional radio communication unit.

And entrusted me to buy electronic components from the outside world that can be assembled into radio stations, and at the same time let me serve as a training instructor for our radio school! ”

Speaking of this, Ding Chenggong sighed slightly, picked up a preliminary radio operation manual on the table, and said with some regret: "Radio communication is a complex science, and its principle alone involves advanced theories such as electromagnetism, electronics, applied mathematics, and so on.

Formal professional training in radio is at least two years. In order to train professional radio communication command personnel, the study period is four years or even longer! ”

Hearing Ding Chenggong's words, every student present showed an expression of disbelief.

Ding Chenggong then said solemnly: "But the murderous and cunning little devil won't give us so much time!" Everyone must also know that the little devil has suffered such a big loss in the skyscraper this time, and he will definitely not give up, and he is already deploying troops at this moment, ready to attack our anti-United Nations!

Therefore, the leadership of the command gave me the task of training all of you into qualified radio operators within twenty days! ”

When they heard that the training lasted only 20 days, the trainees were even more surprised.

Ding Chenggong said very confidently: "I have already made a package ticket in front of Commander Yang, saying that I will definitely be able to complete this task, and now, it is up to you."

Do you have confidence in accomplishing this task? ”

"Yes!"

The squad leader immediately stood up and took the lead in replying.

"Be louder, I didn't hear it!" Ding Chenggong said very sternly: "Didn't you all eat? ”

"Report to the instructor, we are confident!"

The squad leader raised his head, straightened his waist with the students, and replied loudly: "Guarantee to complete the task!" ”

"The slogan is quite loud, but you must remember that it must be implemented!"

Ding Chenggong nodded secretly, but his face was still very serious and said: "Time is pressing, we will start learning the first step now, which is to let everyone assemble the electronic components in this cardboard box into a qualified wireless telegraph!" ”

As soon as the words fell, Ding Chenggong put on white gauze gloves. Lift the box, pour it lightly on the table, and pour all the electronic components inside onto the countertop.

In the surprised eyes of the students, Ding Chenggong quickly selected the electronic original. The telegraph was skillfully assembled.

"The wireless telegraph consists of an oscillator with a frequency of one megahertz, an audio transformer, a circuit board, a headphone plug, a set of springs and wires.

And, of course, there is a battery pack as a power source and a hand-cranked generator. ”

While assembling the wireless telegraph machine step by step, Ding Chenggong explained in detail: "You don't need to explore the principle of these electronic components, as long as you firmly remember their names and functions.

The oscillator is the heart of the transmitter. Another major component is the audio transformer, which adjusts the length of the radio waves to match the loudness of the sound or music we are transporting.

The diode and headset are the core components of the receiver. After assembling, you must remember to set up the antenna and ground wire in time. ”

Under the attentive gaze of the students, a large pile of scattered electronic components, in Ding Chenggong's hands, turned into an exquisite and complete wireless telegraph.

After assembling the wireless telegraph, Ding Chenggong noticed the admiring eyes of the students.

He has been interested in radio communications since he was a child, and has been studying in his spare time since he was a child. He also received professional training in radio technology, but he did not feel proud at all.

He smiled very modestly and said, "Don't look at me like that, it's nothing, as long as you practice diligently, you can do it to this extent, even better than what I did!" ”

Speaking of this, Ding Chenggong pointed to the cardboard box next to the students' desks, and said loudly: "If you want to master the operation skills as soon as possible, you must study hard and practice repeatedly.

Each of you has a cardboard box next to you, which contains the electronic components that can be assembled into a complete telegraph. Now, you can immediately start assembling these originals into a complete radio station on your own! ”

Ding Chenggong gave an order, and the trainees picked up the cardboard boxes, took out the electronic components inside, and began the assembly work according to the schematic diagram sent down and the action essentials demonstrated by Ding Chenggong.

A few more courageous students still wanted to learn Ding Chenggong's movements, and poured the original directly from the box on the table, but they were immediately stopped and severely criticized by the squad leader.

"What's wrong?"

Ding Chenggong hurriedly walked over and asked curiously, "Why don't you let them just pour the electronic components on the table?" ”

"Report to the instructor. These components were finally bought from abroad, and at great risk, they were transported to the base area after a lot of hardships through the blockade of devils and traitors. It is very precious! ”

The young squad leader immediately straightened up and replied seriously: "Therefore, we must treat every electronic component carefully and seriously, and we must not use them simply and rudely!" ”

Looking at the sincere eyes of this young soldier, he must have successfully felt the respect and trust of the soldiers of the Anti-Japanese Federation.

Nodding with deep feeling, he said, "You're right, it's to treat every electronic component carefully and carefully!" ”

Speaking of this, he changed his words and said with a smile: "The task given to us by the leader, but in just twenty days, we have mastered the skills of radio operation.

If you want to master these skills as soon as possible, you must not be afraid of making mistakes, and practice boldly and repeatedly. ”

"But, Mr. Ding......"

The squad leader wanted to explain, but was stopped by Ding Chenggong with a smile.

"It's nothing, you tell Xuemei, don't worry about boldly tossing these electronic components!"

Ding Chenggong smiled heartily: "This time, I brought a large number of such components, which are broken and can be replaced at any time, big deal, next time I will bring more ones!" ”

"Yes!"

The squad leader solemnly gave a military salute to more success, and conveyed his words to every student.

Although he has been encouraged by Ding Chenggong, who is not afraid of being bad, and is bold in practice. These lovely and simple students are still very careful to carry out assembly experiments, for fear of breaking every electronic component.

I couldn't help but be touched to see the students cherish and care for the things they bring so much, and succeed. He also no longer emphasizes letting everyone practice boldly. Instead, he walked among the students and carefully observed the students' practice movements.

As soon as he saw a student whose movements were irregular or made mistakes, he immediately walked to his side, carefully pointed out the mistakes, and patiently taught him to correct them.

When encountering students who have questions and take the initiative to ask questions, Ding Chenggong is even more tireless, patiently and meticulously explaining.

Under the meticulous and tireless teaching of Ding Chenggong's heart, the students who studied hard and practiced hard made rapid progress!

Before you know it, the night is already deep.

Outside the conference room, a melodious lights-out horn suddenly sounded.

Ding Chenggong looked at his watch, only to find that it was already twelve o'clock in the middle of the night.
