In fact, for some things, Hancheng had no choice. The generator was moved to a bicycle, and the wheels of the bicycle were used to drive the electricity. This caused a problem. If you want to use electricity, you have to find someone to pedal a few times on the bicycle.
It takes hours to fully charge. There is a reason why the engine is not used to drive the generator. At least gasoline is extremely expensive, and it is not easy to get some.
"Chief of Staff, Chief of Staff, the light bulb went on!"
Han Cheng, who was resting, was woken up all of a sudden, and after hearing the not-so-surprising news, he got up in a hurry.
"You're going to die!"
Han Cheng cursed helplessly. Ever since he said he wanted to build a telegraph machine, the battalion commander had become a little excited. Some people had to run to pass on to their superiors. But they seemed to have forgotten one thing, that is
The Eighth Route Army's telegraph equipment was only equipped at the brigade level, and you had to use a runner to report to the regiment. Besides, what kind of emergency do you have to report to a battalion? You are looking for death.
"What's wrong with the light bulb turning on? What's wrong with the light bulb turning on? Listen to your radio!"
When Han Cheng came to the headquarters, his face turned green when he saw the mineral radio on the table. There are actually a lot of these things in China, because the technical content is very low, and the entire radio may only have one, or even no tube. This
It is actually good that the gadget can be used, but the problem is that it cannot be used. You cannot build a radio station with a bunch of semiconductor ores.
Mineral radios are also beneficial. It is said that mineral radios do not have oscillators, so counterintelligence organizations cannot detect the monitored frequencies. There are still many 500,000 people using mineral radios to engage in espionage activities. In some modern shortwave
On the radio, you can still hear someone using the call code in an open place, but you don't know what it means.
This thing can only passively receive messages and cannot be transformed into a simple transmitting station, so it is basically impossible. Maybe the only problem that can be solved is the problem of headphones. Headphones must still be used, because
The power is only 6W, and it is difficult to hear clearly without headphones.
"Why can't you use the radios that the comrades collected with great difficulty?"
Several company commanders don't understand technical matters at all. Can this technical matter be the same as fighting? It's really too simple.
"Except for the earphones, this radio is of no use at all. I just said it briefly and haven't given you any specific requirements yet. You guys are so proactive."
Han Cheng saw this pile of things last night and wanted to say something to the battalion commander, but after asking for a long time, the battalion commander was not at the station.
"Come two people and help me move this thing!"
"Battal Commander, where have you been? And where did this radio come from?"
"Stop talking nonsense, there are several more in the back, move them in quickly!"
I was speechless here when I saw the battalion commander bringing in several foreign radios. They were all in big boxes, but many of these big boxes were damaged.
"Hey, where did you get this thing? Your sense of smell is very sensitive!"
"I know what you are looking for. During the Long March, I saw what was inside the radio. It was just small glass. During the war, I found that the radio also had some of them. Don't worry about where you got these things.
Come on, there are a lot of these things anyway, so it’s easy to get them.”
"Have you paid all the money?"
"Yes, they wanted really black ones. They paid 20 yuan for each unit. There are 15 units in total, which cost 300 yuan. If they are all good, they sell them for more than 100 yuan. Now they are cheaper at 20 yuan.
Sold to us."
Han Cheng lifted the radio on the ground and carefully removed it. He breathed a sigh of relief when he saw that the tubes inside were not damaged. He looked at the marks on it and breathed a sigh of relief. There were other tubes inside, but
This tube is the most important.
"Look at what the battalion commander has made, it's just different from yours. What I want is this little thing inside!"
Han Cheng took it apart and put it in front of everyone, letting them take a closer look.
"It is only because of this thing that we can build a radio station. Without this thing, you can't do anything you want! Who, the guard, find me a small box, put cotton in it, this thing is handed over
I will keep them under your personal care, if one of them is missing, I will shoot you!"
Hancheng has dismantled everything available. No one knows how many radio stations can be produced with a few machines. Some things may not develop as imagined.
"What did you find?"
"No, over there, the chief of staff lost his temper when he saw it."
The battalion commander and company commander spoke quietly next to them, and then pointed to the ore radio next to them.
"Can you not lose your temper? I don't even want this thing. The radio station is not a hammer. It's all iron."
It is very necessary for troops in various regions to communicate in a timely manner. Although there is a regiment of troops in the defense area, what if the Japanese invaders gather together from several strongholds to attack one area? Such a situation has not been thought of before, and I have not encountered it yet.
If you arrive, you will encounter it in the future.
For example, in this case, the time it took to deliver a message to the regiment headquarters far exceeded the preparation time, and many of the orders were also very vague, relying more on the improvised performance of the combatants. More importantly, giving a few
The region has developed a joint early warning system. After the Japs in City A leave the city, they will immediately know that as long as the Japs leaving the city do not go to other cities, they are here to raid.
By then, not only the regiment headquarters, but also the men and horses of the three battalions will know, and orders and combat requirements will be more accurate. As for the monitoring and other things, Hancheng does not have the ability to make that thing, so it can only be made to send out signals.
It's just a matter of reporting and receiving things for fun. If it weren't for those things in my head, maybe this radio station wouldn't be built.
"Hey, battalion commander, if we report it to the regiment headquarters, can our radio station be saved?"
"Don't worry, others may really look down on our thing. It's such a small box and doesn't have many specific uses. You didn't look at the brigade commander's side. The antenna is a little higher than the roof.
Our radio is just a small box without an antenna, so how much can it do?"
Han Cheng listened to the words next to him and shook his head helplessly. Who said that if something is small, it cannot be transmitted far. With this simple little thing, the transmission distance can be transmitted from Chongqing to Yan'an, without setting up additional antennas at all. The most important thing is
The reason is that today's China has not experienced the kind of transformation that later generations have, and there is almost no electromagnetic interference, so it naturally spreads very far.
"Prepare a room for me later, and I will build it by myself. From now on, this will be our top secret, and no one is allowed to reveal it."
Han Cheng placed the parts one by one, and then said solemnly to the battalion commander.
