When I was younger, I thought it was really cool how spies used telegraphs in spy movies. But I never knew that the CW technique was still popular among ham radio enthusiasts. I bought a shortwave transceiver kit and, without connecting an antenna, just stuck a flat-head screwdriver into the transmitting port to listen to the side tone. Of course, as expected, I fried the device. It wasn't until my first year of high school that I accidentally came across a post about amateur radio (probably on Zhihu) and immediately got hooked. Soon after, I took the A license exam (I was still underage at the time), secretly bought an USDX, but I never had the energy to set up an antenna. My interest eventually waned, and I ended up selling the device until I finally decided to get back into it during my first year of college in the summer. I should start with QRP!🤣
