Wang Defa's family made ore radios by himself when he was a teenager, so there was no difficulty in actually making them. Pen, fun, pavilion www. biquge。 info

The ore radio designed by Wang Defa's family now has military characteristics, of course, only for this time and space.

Its chassis is a wooden box painted with green paint, which contains a skeleton-type winding coil, a tin foil type variable capacitor, and a tin foil type ordinary capacitor...... These are very easy, a little difficult is the need for a high-impedance headphone, here must be high-impedance, otherwise it will not be able to make a sound.

The others are the simplest, just a pyrite ore crystal, some wires coated with eucommia gum, and some silk enameled wires.

The longer the receiving antenna, the better, and the longer the signal can be received.

A little more difficult is the high-impedance headphones.

Previously, after repeated trial production, Wang Defa's family carefully designed a simple and effective high-impedance headphone.

The materials he uses are: special shaped magnets, iron rods, iron boxes, thin celluloid sheets, and enameled wire.

The specific structure is that the magnet is at the bottom layer, the iron rod is on top of the magnet, the skeleton of the winding coil is sleeved on the iron rod, and then the thin celluloid sheet acts as a vibrating diaphragm at the top layer.

In order to make the thickness of the vibrating diaphragm moderate, Wang Defa's family personally polished no less than ten, tested them one by one, and finally picked out the more suitable ones.

The final test results show that when the antenna is high enough, thanks to the excellent radio environment in time and space, the signal can be received smoothly within the range of 300 kilometers.

Of course, there must be a good enough geographical environment...... Therefore, with the cooperation of the technicians accompanying the team, Captain Huang Zu chose this place, because the location of the hill next to it is the best.

Captain Huang Zu was looking at the old village chief with compassion at that time, and the old village chief was still chewing on his request: I accepted the goods, I hope you can leave here, no matter where you go, as long as you leave here------ I don't care why you came here.

Captain Huang Zu said in a deep voice: "Why are you so afraid of the Tatars, they are not a Chinese clan, they are not a Chinese clan, and they are almost going to eat meat and drink blood to my people, why are you still afraid that we will infringe on you?"

When the real troubled times come, where will there be a paradise?! We don't ask you to cooperate with us, even if you don't know it?!! ”

The old village chief also said seriously: "Zi said: 'The road is not good, you can float in the sea by riding the pole------ you can also hide in the mountains!'" ”

Captain Huang Zu nodded and said: "Yes, if you don't have the ability to change anything, you can escape, naturally there will be capable people for it------ when the capable people act, why do you stop it?"

This is the best reception point for spark wireless telegraphy, and it can't be moved, you know?! ”

“------”

Captain Huang Zu looked at the old guy's puzzled face, his heart was cold, and said: "I wanted you to bring all the fake things back, but I thought that you were also dead along the way, and they were also useful things for us, so I laughed and accepted it, but according to the meaning of courtesy, we can give you some materials equally." ”

After speaking, he waved his hand and asked his assistant to take them to get the objects------ Captain Huang Zu turned around and left firmly, these people were not enough to ------ but his back was a little lonely.

The old village chief wants to say something more, these objects are not gifts, they are fakes, and there is no need to exchange gifts!

However, the team members learned that there was a group of mountain people who wanted to move out of here!

Their real reason was that they thought that their people might bring them trouble, and Captain Huang Zu had previously said that his people were just going to save them!

This is really angry and helpless------ dozens of team members stepped forward, they were in groups of two, each "politely" fighting, and all the young and strong people in those villages couldn't move.

The old village chief was also "politely" held back by a person who claimed to be Captain Huang's assistant.

This frightened the old village chief's son, and he was afraid that his father would have any accidents, but he was also held by two strong men, and he couldn't move for a while.

The old village chief was frightened at first, but seeing that they didn't mean to hurt, he was a little bold, and he was about to shout something, when the person who claimed to be Captain Huang Zu's assistant said with a smile: "This old man, the captain of my family said that the exchange of gifts is the exchange of gifts, if you can send it, we can send it!"

Don't be polite, it's bad for righteousness! ”

After saying that, he took them to the munitions tent------ where the person in charge of logistics glanced at them and found out a general market for their gifts, and gave them back a few pieces of military supplies.

The military assets were cotton linen, canned meat, tea bags, some sugar, and even some small items such as noodles and shoes.

In terms of quantity and volume, it is obviously less than the other party, but the person in charge of logistics puffed up his chest and said:

"These mountain people who don't understand bullshit have made a bargain, not to mention that they are more practical, the price is more than twice as high------ if they send anything again, they will resolutely not accept it, this time we are all fooled, and we think they are taking the initiative to reward our army!"

The person in charge of logistics was by no means talking nonsense, and the military resources of the Guards had always been easy to sell, even if it was ordinary fruit or canned whale meat and venison.

Judging from the advantages of not being bad for a year or two, it is definitely an important procurement project for long-distance sea ships or military supplies of the Great Song Dynasty.

Due to the problem of production capacity, the products produced for a time were mainly supplied to the Liuqiu Guard------ and in the folk of the Great Song Dynasty, it was a very novelty for ordinary merchants to greet guests with Liuqiu canned food.

It is said that in Japan or the Bo Ni region, canned food is only eaten by nobles, regardless of the price, but there is no goods.

Of course, due to the natural characteristics of canned food, and the fact that primary chemical products must be added to it as preservatives, the taste cannot be much better------ of course, it will definitely not be able to eat people, but it will definitely not be good to eat for a long time!

It is a sense of novelty, and the hunger and thirst caused by the main supply of the army, makes it popular in the market.

In addition to cotton linen and tea bags, most of the other items are also the same.

Due to the unscrupulous piracy of handicraft workshops in the Great Song Dynasty, cotton linen and tea bags now basically surpass Liuqiu Island in terms of output, but these products are still good goods for the northern region of the Great Song Dynasty.

No one knows the markets of the North better than the one in charge of logistics.

The old village chief, his son, and the young men in the village were all "gifted" away by the team members.

After they had been "gifted" for a while, they looked back and saw that there was no one to give them away, so they stopped to rest, although they did not bring much in return, and they did not go fast, but everyone was worried that those people would shoot crossbow arrows in their backs, or slash their own steel knives, and they were all nervous, and they seemed to be more tired than when they came.

The people who "gifted" them, all of whom carried crossbows and steel knives, and with smirks------ villagers could sense that they didn't like them.

Fortunately, no one was harmed, and the old village chief put down the gift they had sent back, feeling that the gift seemed to be a failure, and that there was some shame, but he still did not understand why the young leader looked at him with sympathy.

He was a little angry, and wanted everyone to throw each other's return gifts into the forest, even if they fed the mountain wolf, but after careful inspection, they were reluctant------ so they should bring it. (To be continued.) )
