ABOUT K9CHU
Radio, experimentation, and staying connected.
K9CHU is an amateur radio station focused on radio experimentation, digital communications, RF projects, antenna systems, repeaters, and hands-on technical projects. This site documents station equipment, ongoing builds, operating activities, and other amateur radio projects, in collaboration with neighboring operators and group stations.
The lighthouse theme comes directly from the K9CHU logo — a visual fit for radio: a fixed signal, a recognizable identity, and a beacon that reaches well beyond the shoreline.

What’s on the bench
DIGITAL
XLX722 Reflector
XLX722 is a multi-mode digital reflector that bridges D-STAR, DMR, and Yaesu System Fusion, allowing operators on different digital modes to meet in shared reflector modules — essentially a common chat room across modes.
