Created for repeater owners, trusted by operators, and built on the belief that amateur radio data should be open, accurate, and free.

The Amateur Repeater Directory (ARD) makes repeater data free, open, and community-maintained. Hosted on GitHub and fully open source, ARD is a transparent alternative to closed databases.

ARD uses real elevation and line-of-sight analysis to find repeaters you can actually reach. Search a radius and it may reveal a repeater 180 miles away — not by guesswork, but by terrain and physics.

You can mark yourself online on a repeater, and the live activity map shows where conversations are happening. Yon can also subscribe to a repeater, when changes are made to it's settings, you are alerted.

ARD is lightweight and fast — pure HTML, JavaScript, and Bootstrap. No frameworks. Easy to contribute.

What sets ARD apart is ownership and openness: repeater owners maintain their listings, operators improve the data, and the community builds the directory together.
