About The App

Latry - A Mobile SvxLink Client

Latry is an application that lets amateur radio operators connect to digital voice networks from mobile platforms. It functions as a client for SvxLink, allowing you to join talkgroups on SvxReflector systems or HAM TETRA networks and chat with other users over the internet.

After entering your server host, port, callsign, authentication key, and desired talkgroup, Latry establishes a secure connection and handles audio streaming using the Opus codec.

Latry supports displaying names for other users on the network when available. Settings are saved locally, so your server details are ready the next time you connect.

This project is provided for hobbyist use and is not affiliated with the official SvxLink project. Use it responsibly and comply with your local amateur radio regulations.
