When Wang Weidong went home to cook at night, he heard his grandmother's relay, and he hurried to find his father Wang Haifu.

Wang Haifu carefully told his son about his understanding and asked: "The work problem will be solved sooner or later, take your time, how good it is to find a job in peace, don't be a moth!" ”

"Am I doing it for myself? I am anxious for disabled young people like Liu Jianguo! What is my own interest when I think of them! Wang Weidong replied loudly.

Wang Haifu was choked by his son and couldn't speak.

"It's too late today, you should prepare to go tomorrow morning." Wang Haifu said helplessly.

Wang Weidong rushed to Liu Jianguo's house in a hurry when he went out.

Liu Jianguo's parents are at home, and the three of them have finished eating.

"Jianguo, tomorrow I will go with me to report to Director Shi about the establishment of the radio factory that we have discussed, and the two of us will discuss it tonight, at least draw a radio drawing." Wang Weidong said.

The director of Xiangyang Chemical Plant is a director-level cadre, and he is at the same level as the leaders of Mushi District, and now the director of the factory actually has to listen to the report of two hairy young men.

Liu Jianguo's parents are also people who have seen big leaders, but they still widened their eyes in surprise when they heard Wang Weidong say this.

Liu Jianguo saw Wang Weidong winking at him and knew that he was pretending to be his mother's letter to the leader.

Liu Jianguo took Wang Weidong to his hut.

Wang Weidong pointed to stacks of radio magazines and said: "Pick a simple line from these magazines, trace the circuit diagram on it, and the shell, and tomorrow we will take the map to report to the factory director." ”

"It's a lot simpler, what kind of one are you looking for?" Liu Jianguo asked.

Wang Weidong thought for a while and said: "The volume should be small, the structure should be simple, the fewer parts the better, and the installation should be fast and the cost should be low." Also, there is a large battery number one installed in the radio. ”

Nowadays, people's income is low, and buying batteries is also a big expense, and large batteries can save more.

No one had ever heard of the word intellectual property in this era, and Wang Weidong and Liu Jianguo looked through dozens of radio magazines and found a few suitable radio drawings for comparison.

"I think this radio is more suitable, it only has two filters, and the structure is very simple." Liu Jianguo opened a magazine and handed it to Wang Weidong to read.

"What does filtering mean?" Wang Weidong asked.

Liu Jianguo thought about how to explain it so that Wang Weidong could understand.

"It's just to make the radio a little less noisy and listen better." Liu Jianguo said.

"It is enough for the radio to be able to receive one national station, three provincial stations and three local stations with good listening effect, and there is no need to filter to listen to news commentary and cross talk." Wang Weidong said.

Recently, in addition to commenting on stories, Master Hou, who said cross talk, has come out of the mountain again, which is very popular with the masses.

Liu Jianguo is a radio enthusiast and pursues excellence, so he disagrees with Wang Weidong's opinion.

However, Wang Weidong insisted very much, and in the end, the two reached a compromise with only one filter, saving a triode and several resistors, and simplifying the circuit.

In the end, Liu Jianguo's drawings showed a radio with only a dozen components, including horns, magnetic rods, diodes, triodes, resistors, and capacitors.

Liu Jianguo drew the radio shell on the magazine as it was.

This radio has the word red plum in the lower right corner, which is the trademark brand.

"Keep this place for now, and let Director Shi name this radio when I report tomorrow!" Wang Weidong said.

He felt that the stone director must be very willing to do this.

"Can we make such a simple radio tonight, and it will be better to play it in front of Director Shi tomorrow." Wang Weidong said.

"But I don't have all the components here, so I probably won't be able to make this radio." Liu Jianguo replied regretfully.

"What's missing?" Wang Weidong asked.

"There's still a triode and a couple of resistors left, and there's no magnetic rod." Liu Jianguo replied.

"Don't you have a radio at home, I'll bring my radio at home, so I can make this radio together! It's a big deal to dismantle it when it's used up. Wang Weidong said.

Without waiting for Liu Jianguo to answer, he turned around and left.

Running home, Wang Weidong saw his grandmother sitting on the kang listening to the radio, Wang Weidong picked up the radio without saying a word and ran out!

Back in Liu Jianguo, Wang Weidong saw Liu Jianguo cutting a piece of paper shell with scissors.

"If you don't have a circuit board, use this to deal with it, and then connect it with wires." Liu Jianguo explained.

Measure the resistance on the radio with a multimeter and remove the appropriate one. If you can't find it, you can only deal with it by one or two ohms to see the effect.

Wang Weidong sat on the sidelines and watched Liu Jianguo insert the legs of each component into the paper shell, then connect them with wires, and finally weld the wires to the positive and negative poles of a battery.

Twisting the capacitor switch, Wang Weidong heard a clear click from the speaker.

Liu Jianguo turned the knob and there was a rustling sound in the speaker, and then a clear voice was heard, this was the national one.

"Transfer to the provincial station! Tomorrow morning, we will wait outside the factory director's office at six o'clock, and we will follow up when the factory director goes to work at seven o'clock. Wang Weidong explained.

Liu Jianguo carefully rotated the knob again, and after a while, he heard a clearer voice: "If I'm hungry, I'll come to two taels-"

Wang Weidong and Liu Jianguo couldn't help laughing.

The provincial station is now broadcasting the cross talk "Drunken Song", which is performed by a very famous young cross talk actor surnamed Shi in Hei Province, and the cross talk is humorous and very popular with the masses.

Today, Wang Weidong and Liu Jianguo feel very different when they listen to this cross talk, this is the fruit of their labor and their hope for the future!

"The founding of the country, we must work hard for our better tomorrow!"

Liu Jianguo nodded heavily.

At half past six the next morning, on the way to the production area of the factory, Wang Weidong stretched his hands forward and carefully held a cardboard box, and Liu Jianguo followed closely behind on crutches.

The two of them walked into the small building of the factory office and walked up to the second floor to stand outside the factory director's office.

At about 7:5 a.m., the director of the stone factory rode his bicycle to the bottom of the office building. He locked his bicycle and went up to the second floor to see two young men standing at the end of the corridor.

Wang Weidong, who was holding the cardboard box, hurriedly came up and bowed and said: "Director Shi, I am Wang Weidong, and I came to report my thoughts to the leaders today!" This is my classmate Liu Jianguo, and we are together. ”

"You are the grandson of Master Wang? Are you the son of the rich master? They are all the successors of the old workers. Come with me into the office and talk! Director Shi said enthusiastically.
