Echolink: Connecting Ham Radios via the Internet
Echolink is a revolutionary system that combines traditional ham radio communication with the power of the internet. It allows licensed amateur radio operators to communicate with each other using their radios, computers, or smartphones, regardless of geographical location. This guide explores the features of Echolink, its benefits, and how to get started with this innovative platform.
What is Echolink?
Echolink is a software application that enables licensed amateur radio operators to connect with other operators around the world via the internet. It integrates Voice over IP (VoIP) technology with amateur radio, allowing seamless communication between radio stations and internet-connected devices.
How It Works
Echolink nodes (stations) can be linked to repeaters, simplex nodes, or individual computers and smartphones. When a transmission is made, the audio is converted to digital data, sent over the internet to the remote node, and then converted back to audio for transmission over the air or playback on the receiving device.
