BBC and Encompass have been transmitting DRM for testing the distribution of audio, text and graphics in parts of the world where the internet is not available.
The broadcast has been transmitted via a shortwave RIZ transmitter, which has been upgraded by RFmondial’s DRM Exciter LVe to be capable of performing DRM as best as possible.
On Wednesday 29 June 2022, ABC, the public broadcaster, and the Australian network operator BAI hosted a demonstration of Digital Radio Mondiale (DRM) on both AM and FM in Wangaratta, a location in the state of Victoria with the support of the DRM Consortium and some of its key members, including RFmondial.
Hannover - In the event of a failure of the distribution link (modulation lines) to digital radio transmitters (DAB+), a stable radio broadcasting provision to the population must be guaranteed. As recent events have shown in the event of a disaster, broadcasting coverage in particular is an essential building block for informing citizens, since mobile phone networks are usually the first to fail. In order to increase the reliability of the broadcast an alternative distribution must be used during standard link failure (land-based lines in the event of flooding or satellite reception in the event of storms).
