DDS meets DRM

An Experimental DRM Receiver
Did you know that the BBC transmits digitally on shortwave and medium wave? The only trouble is DRM (Digital Radio Mondiale) radios are not widely available yet. This article describes how the Elektor Electronics DDS RF Signal Generator can be used together with a little extra hardware and some software to receive these high quality stereo broadcasts on a PC or Notebook.The new digital broadcasting standard for short wave radio (and all bands below 30 MHz) is known as Digital Radio Mondiale (DRM). The system requires a high specification for the receiver but if you’ve already built the Direct Digital Synthesiser (DDS) frequency generator described in the October issue of Elektor Electronics the rest of the receiver design is simple. An alternative receiver design is also included in this article that does not need the DDS generator.
