I’m a programmer with a passion for electronic circuit design and amateur radio in my spare time. This blog will document some of my recent small circuit projects related to amateur radio, along with the challenges I encounter and the thoughts I have during the development process. Through this blog, I hope to summarize what I’ve learned, improve my English skills, make new friends, and share the joy of building and experimenting. If possible, I also hope to connect with more fellow amateur radio enthusiasts and exchange QSL cards.
