JOHANNESBURG, South Africa - Johannes von Weyssenhoff, representing the community station Wecodec in Johannesburg, presented the case of DRM to an international audience at the "Radio Days Africa," an annual event taking place at the Witwatersrand University in Johannesburg. His presentation also included results and findings of WECODEC's ongoing DRM+ trial, the first of its kind on the African continent, according to DRM news.
The trial has demonstrated that there is no interference with analog stations on either side of the digital signal in the crowded FM spectrum of Johannesburg. The DRM power for the test is 1/4 that of FM, giving similar coverage at 4QAM.["]
