On World Radio Day, the world celebrates one of the most trusted and resilient mediums on earth. Radio remains immediate, intimate and free — a companion in cars, kitchens and communities.

And this year, HOT 1027 isn’t just celebrating radio’s legacy — it’s actively shaping its future.

The station has officially joined South Africa’s Digital Radio Mondiale (DRM) FM trial, becoming one of the pioneers testing what could redefine broadcasting in this country. Broadcasting from Northcliff and covering parts of Johannesburg, the trial marks a significant leap forward.

So what exactly is DRM?

As Aldred Dreyer from the DRM South Africa Group explains:

“DRM is the digital equivalent of FM. You could say that DRM is the cousin to FM.”

Just as television and mobile phones moved from analogue to digital, radio is now entering that evolution.

“Radio is the last of those that still needs to go through this digitisation process.”

Currently, one FM frequency carries a single station. DRM changes that entirely.

“You’d be able to have three programmes and a multimedia service on one frequency.”

But the real opportunity lies in what this means for countries like South Africa. DRM uses spectrum far more efficiently — a crucial advantage where infrastructure and bandwidth are limited. It can transmit text, images, educational content and emergency alerts without relying on mobile data or fibre. In areas where internet access is expensive or unreliable, that could significantly expand access to information.

For listeners, the radio experience becomes richer too — clearer digital sound, on-screen song titles, news headlines, traffic updates and even multiple language streams — all while remaining free-to-air and accessible.

For now, only those with DRM receivers can tune in. But as the technology develops, one thing is clear: on World Radio Day, HOT 1027 isn’t just celebrating radio’s past — it’s actively helping shape its future.
