Chen Zuwang said in surprise: "Master, isn't this magic? It's like transmitting a message thousands of miles away."
Yaoguang has made it clear that if you develop basic principles and equipment and break through the boundaries between what you have and what you don't have, you can purchase more advanced equipment through teleportation. You cannot teleport in areas where there is no breakthrough.
Yang Fan is preparing to set up an electrical and electromagnetic research team. The wires have already been made. With wires like enameled wire, both hydroelectric generators and thermal generators can be made. Winding and rotors are not difficult tasks.
The principle of electromagnetism is not complicated. With modern data, it is not a problem to make primitive wired telephones and telegraphs. Radios can also be made. The next step is to purchase vacuum tubes from modern times and assemble old-fashioned radio stations.
In this era, without electromagnetic interference, a very low-wattage shortwave radio station can complete nationwide broadcast transmission. If you purchase modern obsolete analog shortwave equipment, achieving global broadcasting in this era is not a problem.
Yang Fan is considering the next step, how to realize the communication problem of the navy. After all, it is very inconvenient on the vast sea without advanced communication and contact means.
Yang Fan went on an expedition after the Spring Festival. He had no radio equipment and it was not conducive for him to keep track of the trends in the new city and grasslands at any time.
"Master, look, there is a fleet ahead, it seems to be the navy's fleet." Mingyan said.
Yang Fan picked up the telescope and looked ahead. Here we have entered Hangzhou Bay. Today, we caught up with the tide and moved through it very quickly.
In the distance is a long fleet of seven Guangzhou ships. The Guangzhou ship type is so named because it is mostly built along the coast of Guangdong. Its basic characteristics are long pointed nose, small beam arch, and low deck ridge.
The transverse structure of the hull is composed of tight ribs and bulkheads, and the longitudinal strength is maintained by the keel. The structure is solid and has good seaworthiness and endurance.
Looking at the flag fluttering on the mast, it says Dongjiang Town General Soldier, Left Commander Mao.
"Mao Wenlong's fleet, if they are not guarding Dongjiang Town, why are they coming to Hangzhou?"
