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.

If possible, I also hope to connect with more fellow amateur radio enthusiasts and exchange QSL cards.
