Australia successfully tests DRM in AM/FM

On Wednesday, June 29, 2022, the ABC and the Australian network operator BAI hosted a demonstration of Global digital radio (DRM) on AM and FM in Wangaratta, a location in the state of Victoria.

The demo was the culmination of nearly two years of COVID-impacted work to assess the performance of DRM services on the VHF and MF bands.

Senior representatives from public, commercial and community stations, the regulator and interested parties, including the ABC, SBS, ACAA, RNA, ACMA, TONGUE and ACE-Radiotraveled to the regional sites to view the installation and, more importantly, to experience the audio quality available via the DRM signals on the MF (AM) band of Wangaratta MF and the VHF (FM) band of Mt Baranduda.

Attendees visited the MF site in Wangaratta where a simulcast of AM and DRM services were operating and were able to see the transmission equipment.

In the parking lot of the local Rovers Football Club, two vehicles were set up with receivers for stationary listening and demonstrations of emergency alert capabilities to ‘wake up’ the radios.

The third part of the demo consisted of test drives for participants to demonstrate on-the-go audio quality and the ability to switch between AM, FM and both DRM signals.

Feedback from attendees was universally positive.
