Digital Modes Overview

Digital modes allow radio operators to send information using computers and radios working together.

These modes may be used for keyboard messaging, weak-signal communication, position reporting, voice, or data transfer.

What is this page about?

This page introduces digital modes in amateur radio and explains why they are useful for modern communication and experimentation.

Digital modes can often work well under weak-signal conditions and can provide efficient communication when voice operation is difficult.

They are also useful for experimentation, data transfer, and linking radios with computers.

Many digital modes require a radio, a computer or control device, and some form of audio or data interface.

Some digital voice modes may also require radios designed specifically for those systems.
