APRS

APRS (Automatic Packet Reporting System) is a digital communication method used by amateur radio operators to share real-time information like location, weather data, messages, and station status. It works by transmitting small data packets over radio frequencies, which are then received and displayed on maps or devices, allowing users to track each other’s positions or exchange messages instantly. Think of it as a specialized, radio-based social network that enables operators to monitor and share information across distances without relying on the internet, making it useful for emergency response, event coordination, and hobbyist activities.
