Stop playing A immediately and download a MorseMania software to learn how to send Morse code. Practice for six months.
Then, pass the B exam, buy a shortwave radio with a 100W machine, and obtain a license that allows for transmission up to 15W. Using Morse code with a MA-50 vertical antenna, you can essentially communicate globally. If using voice SSB (Single Sideband), the effectiveness of transmission depends on the propagation conditions.
You can learn Morse code and use it to communicate, and you'll be able to talk to anyone, anywhere. Holding a handheld radio, using the local repeater – what technical skills are involved? You need to study space weather, electrical equipment, signal propagation... Right, that gives you a direction for your university major and career path, as well as potential employers like the meteorological bureau, broadcasting companies, and the regulatory authority (No委). If your work and hobbies are related, wouldn't that make life more comfortable?
