How a link works

  • Your radio hears someone and passes the audio to a small computer.
  • The computer sends it over the internet to another node.
  • That node plays the audio into its own radio, and the people near it hear you.

What you need

  • A license that matches the radio service you link
  • A radio, an interface, and a computer or hotspot
  • A stable internet connection
  • Permission from any repeater owner you link into

Good habits

  • Listen first. Linked systems can have people all over the world on them.
  • Say your call sign clearly, keep it short and keep it clean.
  • Check each network's own rules before you connect.

General information, not legal advice. Check the current FCC rules before you transmit.
