The chair of Digital Radio Mondiale, Ruxandra Obreja , writes, "a picture is worth a thousand words and a digital radio coverage map might be worth a million dollars or more in business.

"We might stress in documents and presentations the undeniable benefits of digital radio: Better audio, extra data, more choice, emergency warning capability and less spectrum. For DRM specifically the list also includes, the capacity to offer improved audio and data for large or local coverage very often using the existing basic infrastructure."
