Warship of Great Power

  Chapter 73 Radio Debugging

  Huating Shipyard, Wharf.

  The 7,000-ton ro-ro ship has been built and outfitted, and the only thing left is the final radio adjustment.

  Director Wang stood on the pier, looking at this brand new ro-ro ship with anxiety on his face.

  The old Shanghai car drove directly to the pier, and several people came down from it. When he saw them, Director Wang finally breathed a sigh of relief: "You guys are here."

  Among the few people, the leader Zhang Dagang said: "Director Wang, we are willing to do our best to help, but we have never touched this equipment before, and we are not sure about it."

   "You go ahead and do it. If it goes bad, it's mine. If it's done, it's yours." Director Wang said.

Of course he knows the risks involved. This set of equipment was designated by the Belgian shipowner. The shipyard is only responsible for the installation, and the commissioning is not their responsibility. But now, the person in charge of commissioning in the contract does not come, and the shipowner refuses to accept it Boat.

   I can't wait, what should I do? Let's treat a dead horse as a living horse doctor. These technicians are all engaged in missiles.

   Several people walked onto the bridge of the ro-ro ship and came to the front of the radio equipment.

  In the initial era of great voyages, ships did not have any communication equipment. If there was an accident, they could only put a drift bottle and expect to be picked up by other crew members. This probability is much lower than buying a lottery ticket.

  Later, simple wireless stations began to appear, but their power was not large, and the distance for a call was only tens of kilometers, but the distance for sending a telegram could be thousands of kilometers. Internationally, special frequency bands have also been stipulated for ships to use.

  Up to now, the radio equipment of ships has become a system, and there are clear requirements. Alarm, communication, radar positioning, and receiving maritime safety information, these functions must be complete. In the future, after the emergence of high-end global positioning systems and maritime satellite phones, these functions will also be necessary.

  In order to meet these requirements, a reasonable combination is generally selected. Currently, the usual A plan used on this Norwegian cargo ship includes Taiwan ship ground station, direct printing telegraph sending and receiving alarm, watch, and line telephone or DPT communication. The station is fully equipped with DSC and line telephone functions and MFInstallation (line radio station) for DSC on duty to meet the needs of DSC alarm sending and receiving, line communication and on duty. There is also a device in the 406MHz frequency band that sends an alarm to the shore and is in distress, which is realized through a special polar satellite.

  These three devices are all installed in a cabinet. No one knows how to debug them.

   "Give us the instructions." Zhao Dagang said.

   "Here is the manual." Someone immediately handed over the manual.

   Zhao Dagang took it over, opened the instruction manual, and was immediately dumbfounded.

   Japanese? How can I use Japanese as an instruction manual? These guys clearly did it on purpose!

  Generally speaking, the international language is English, and the instructions of machines exported from various countries are written in English. Zhao Dagang and his technicians have also learned English a long time ago, so they can communicate with the world and communicate in pure English without translation.

  However, it is good to know a foreign language, but it is difficult to know other languages.

   Looking at the Japanese explanation, Zhao Dagang was a little annoyed.

   "Why is there no instruction manual in English?"

"I don't know either." Carrasco, the pick-up representative sent by the Belgian shipowner, spread his hands, and then looked at his watch: "Now, it is less than twenty-four hours before we pick up the ship. Please hurry up."

   "Let's study the circuit diagram quickly." Zhao Ergang said.

  Circuit diagrams are common symbols all over the world, so there is no way to make a fuss about this. It is useless to talk to the other party now, so we should quickly compare the circuit diagrams and study the circuits.

  However, from front to back, there are only wiring diagrams, no detailed circuit diagrams at all! What is this manual?

   "Let's do the wiring." Zhao Dagang took a deep breath.

  Input and output ports, you can refer to the wiring diagram and try to connect them.

   Everyone is holding their breath, if you connect the wrong wires and burn the equipment, it's all over.

  Carrasco watched with interest as the cables were installed one by one. An hour later, Zhao Dagang let out a long breath: "Now, we can power on and test."

  The gate of the circuit switch was closed by Zhao Dagang, and the switches were opened one by one, and various indicator lights flashed. Zhao Dagang turned the **** of the radio station with his left hand, picked up the communicator with his right hand, and pressed the switch.

   "This is the ro-ro ship that is about to be delivered by Huating Shipyard. I request to test the radio equipment with the Guangzhou station. Please answer if you receive it. Please reply if you receive it!"

  He released the switch, but there was no sound. After waiting for more than ten seconds, he pressed it again and called again.

   Still no answer!

what happened?

  Zhao Ergang looked at the display instrument on the radio station and frowned: "The frequency oscillator of the transmitter is not working!"

   Regardless of any radio equipment, a frequency oscillator is required to provide the original signal, and then through modulation, add sound or other signals, amplify and send it out. If the oscillator does not work, there will be no output at all.

"This equipment is broken when it leaves the factory!" Xu Qiang said: "It is impossible to debug at all! Even if the equipment is reordered, it will take a week or two to transport it from abroad. Because of this reason, the delay in delivery is not ours. Responsibility!"

   "NO, NO, NO!" Carrasco shook his head like a rattle: "No matter what the reason is, it is your responsibility that you did not deliver the ship on time. Even if there is a problem with the radio, it is because you did not find it early."

   "We are not responsible for debugging at all!" The young and energetic Xu Qiang was annoyed, and his voice was louder: "It is the Norwegian service provider who did not come to debug, and they are responsible! The compensation is also paid by them!"

  Director Wang smiled wryly at the side. They had already raised this point of view with the shipowner, but it was useless.

"You are the general contractor, the delay in delivery is your responsibility, and the compensation is your responsibility. As for the Norwegian service provider, it is a commercial dispute between them and you, which has nothing to do with us. In short, the delay in delivery, we Just follow the contract." After finishing speaking, Carrasco looked at his watch again: "It's less than twenty-two hours now, instead of wasting time arguing with me, you might as well hurry up and fix it."

  Fixed? How to fix it? The instruction manual is in Japanese, and there is no detailed circuit diagram yet!

   "It doesn't take twenty-two hours, two hours is enough." At this moment, a voice came from outside, and a young man and two women came up from the gangway.
