Heritage On The Air

Preserving Our Heritage Through Amateur Radio

Discover HOTA

What is HOTA?

Heritage On The Air is an amateur radio initiative that motivates operators to discover, learn about, and preserve history by activating historical sites across South Africa using SSB, AM, FM, CW and even Heliographs.

Activate Sites

Set up your station at registered heritage sites and make contacts to earn activation points and bring history to life on the airwaves.

Chase Activations

Contact activators from anywhere in the world. Log your contacts and climb the chaser leaderboard while learning about heritage sites.

Explore Heritage

Discover South Africa's rich cultural and historical landmarks. Every activation helps map and preserve our shared heritage for future generations.

Our Three Pillars

Amateur radio, historical landmarks, and cultural heritage come together in HOTA.

Our Heritage

A concerted effort to preserve our heritage is a vital link to our cultural, educational, and inspirational legacies.

A people without the knowledge of their past history, origin and culture is like a tree without roots. — Marcus Garvey
