Looking at the familiar old panel in front of him, Yang Heng smiled, after months of hard work, he finally had new achievements.

Yes, it's the familiar old panel, with a gray panel background, black knobs, glass-faced meter hands, black bezels, and red indicators.

The so-called old-fashioned, but also just the old-fashioned in memory, in the more than ten years before Yang Heng crossed, this style of panel has been eliminated, yes, this is the new radio station in the academy laboratory, or short-wave radio, however, the technicians still did not follow Yang Heng's requirements to make small, can carry the radio on the back out, even, these stations are not the so-called single-sideband radio, and even, this is not a carrier radio, so, the sound of this radio station has serious distortion, however, it can also be understood, this is enough.

Originally, Yang Heng handed over the development of the radio station to those technicians, but they really didn't know what short wave, what medium wave was, what long wave was, what the ionosphere was, and how the ionosphere reflected radio wave signals, so Yang Heng had been guiding them in the laboratory, such as what was open circuit emission and what was resonance.

But how to measure the frequency of this resonance, frequency meter, now Yang Heng really can't do it, besides, now he doesn't need a frequency meter, so okay, I have to test the resonant coil capacitance one by one, compare, until the exact same parts are selected, coils, as a metal laboratory, they have made some simple short waveguide magnetic rods out, so the resonant coil is also available. Capacitance. The best silver-plated ceramic capacitors are now used.

And also. The latest air fully adjustable copper sheet capacitor has also been manufactured by technicians, where is the difficulty of this, the difficulty lies in the mechanical part, when rotating, the mechanical part must be ruthless and stable, so as to ensure the distance between the copper sheet and the copper sheet, and to ensure that the capacity of the capacitor is a smooth curve change when rotating at a uniform speed.

And variable devices. Naturally, there can not only be one kind of adjustable capacitor, but also trimming capacitor, carbon film adjustable resistance, wirewound adjustable resistance, carbon film fine-tuning resistor, wirewound fine-tuning resistor. There are also fine-tuning inductors, the emergence of these adjustable parts, really ensure the normal use of the station, but also allow the station to adjust the frequency, but. Now on the use of a radio station, then. The use of adjustable radio stations is unnecessary, and the only thing that is needed is the contact of long-range long-wave radio stations of thousands of miles, and the contact of short-range tens of miles or even miles is connected by short-wave radio stations.

With the radio, this is one of the guarantees for the wedding, and then, it is the emergence of the new steam-powered car, the reason why Yang Heng can agree to the wedding according to the requirements of the Cui family is also because of the car, the real practical car has been manufactured, although this car is still very ugly, just a carriage, with a power system on it, a drive system, and even, only two people can sit on it, but a trailer can be added to the back, and a four-wheeled carriage can be added to the back, isn't it able to pull people, and this carriage, Directly converted into a half-compartment carriage, people sit on it, can expose the upper body, and even in order to block the wind, a large glass is erected in front.

In this way, as a wedding, all kinds of dowries can be placed on these carriages and pulled by cars, which is not only novel, but also allows onlookers to see what the dowry is.

Only this is still not possible, because the front of the car is to pull two people, however, there is still some space on it, these spaces, can completely put down a single unit, and then, and then in the space of the seat according to the installation of the generator, so, the power problem of the radio station has also been solved, in this way, in the process of traveling, the front car can be connected with the rear car, however, Yang Heng is each car to install a radio, the head car is the commander-in-chief, the tail car is the deputy commander.

In order to keep it secret, Yang Heng specially vacated one of his Zhuangzi, and let the villagers in the Zhuangzi go to another Zhuangzi to borrow it, and this Zhuangzi has now become a vehicle driver training class, and the new automobile factory is also working overtime to manufacture new cars, so as not to delay the time to welcome relatives.

"Husband, you really have a way to pick up your younger siblings from a hundred miles away within a limited time." Changle looked at Yang Heng with some concern. "Hey, you dare to doubt your husband, see how I teach you." This, after having the same room, Yang Heng is more and more engaged in some activities that are inappropriate for children with Changle regardless of the occasion.

"Giggles, husband, don't dare, don't dare to do it, don't do it, someone is watching, it's a big deal to ...... at night" "Okay, for your sake of begging for mercy, I'll take you to see my new weapon."

"Husband, is there a train that doesn't rely on rails?" "Haha, lady, this is not a train, this is called a car, come, come up, I'll take you around and have a look."

"Giggles, giggles, husband, this car is running really fast, it's a little louder, if you use this to pick up relatives, it can really be done, but, husband, there is no cement road in that direction, I don't know, this car can be done on the dirt road." Changle was still a little worried.

Why can Changle know that there is no cement road in that place, because there is a map in Yang Heng's home, and this map is a map about these traffic.

"There is no cement road, lady, don't worry about this, you know, there is a train station over there, besides, there is a good road from the Cui family's Zhuangzi to the railway station, which is enough, to Chang'an, you say, what else do we have to worry about." Yang Hengda said with a smile.

"But, husband, if you use the train, do you need to change trains, and in the process of welcoming relatives, can these dowries or something be transferred?" This kind of thing is really something that no one has ever seen, so Changle is worried about this.

"Don't worry, lady, we won't change trains halfway, I'm also making the train, when the time comes, directly let the car pull the four-wheeled carriage onto the train, it's not done, when you get here, let the car come down, so that no matter what the personnel, there is no need to change any tools on the road halfway."

While speaking, Yang Heng pulled Changle to a new training place, and saw that there were several cars in front of him moving forward in a long road drawn with lime, and this road was painted with a frame, in fact, this is a road drawn after the train tablet, and then these drivers will be allowed to drive the car directly from the slope to climb directly onto the train tablet, and there can be no command staff on the train tablet, only some people who run with the car stand on the side of the benchmark, Also, the staff at the train station will say hello loudly.

Why do we have people who stand on the pole, this is to let them strengthen the vehicle, and when the car is stopped on the train, they stand on both sides, one by two, one by two, to prevent someone from understanding when the train is moving, and not to turn the happy event into a funeral when the train is moving.

Moreover, the personnel of these station benchmarks are now also training at the railway station, that is, how to stand firmly on the tablet during the movement of the train, and how to strengthen the car and horse-drawn carriage on the tablet.

"How about it, lady, if I use these cars to greet my relatives, it will be okay." "Cheng, although you have changed some of the old rules of welcoming relatives, but this is also what they forced, isn't it, or, husband, when you go to pick up Changle, you can also use a car, don't Yang Hu use a car to welcome relatives, you still use a sedan chair or something, besides, so that I can balance my heart a little."

Yes, Changle said it directly, she wanted to be psychologically balanced, you know, it was relatively simple when she married Yang Heng at the beginning, but this time Yuzhang is much more luxurious than Changle, and I don't know what Li Er thinks, do you want to show off, however, have you thought about Changle's thoughts.

If it is said that it is changed to a car, then neither Changle nor ordinary people can compare, which means that no one will lose face.

"Cheng, lady, I promise you, this is very simple, let the factory speed up the production, or I will change their work to three shifts.

Could it be that the three-shift work method, this is not possible? (To be continued......)
