RFChat

No internet, no account, no server. RFChat turns compatible amateur radio gear into simple offline group chat over AX.25, with TCP and Bluetooth LE support.

RFChat is an offline group-chat client for amateur packet radio. Connect to a KISS-compatible TNC over TCP or Bluetooth LE and exchange short messages as standard AX.25 UI frames — no account, server, or internet connection required.

FEATURES • Offline rooms and directed messages • KISS over TCP and Bluetooth LE • Local message history, members, channel monitor, and position reports • Explore Offline mode for trying the interface without radio hardware • English and Simplified Chinese • No ads, analytics, or tracking

Radio transmissions are public by nature. Transmitting requires a valid amateur radio license and compatible equipment. RFChat is not for emergency communications, and delivery is not guaranteed.
