Amateur Radio
Experiment, communicate, and keep learning.
My amateur radio callsign is KD9YTT.
From cybersecurity to software-defined radio
My interest in amateur radio began with software-defined radio (SDR) and its applications in cybersecurity. Exploring how to observe and listen to electronic signals drew me into the radio side of technology.
That starting point grew into a fascination with amateur radio and the possibilities of SDR. I enjoy following the connections between cybersecurity, electronics, and the signals around us.
A hands-on way to explore radio
Amateur radio brings communication and technical curiosity together. The hobby spans local conversations, long-distance contacts, antennas, electronics, and digital modes. It offers many ways to learn how signals travel and how equipment, operating technique, and conditions shape a connection.
Clubs and experienced operators can help newcomers learn the practical side: choosing equipment, understanding operating practices, and making those first contacts. In the United States, transmitting on amateur bands requires the appropriate FCC license and operating privileges.
