									DRM Decoder/Demodulator Plug-in for WiNRADiO G313 Series Receivers

                        This DRM Demodulator/Decoder Plug-in makes it possible to receive and listen to DRM
                        transmissions on a WiNRADiO G313 Series receiver. DRM (Digital Radio Mondiale) is a non-
                        proprietary digital system for short-wave, medium-wave and long-wave bands which offers a
                        dramatic improvement over conventional analogue AM transmissions with its near-FM quality of
                        sound.

                         For this project, WiNRADiO joined forces with VT Merlin Communications to develop and provide a
state-of-the-art DRM decoder and demodulator for the WiNRADiO G313 receivers, which have now become fully integrated
DRM-capable receivers, the first of its kind, pioneering the DRM technology for the benefit of the radio enthusiast and
professional community.


The DRM Demodulator/Decoder is an XRS Plug-in which, upon installation, can be selected from the G313 receiver
Demodulators top bar menu, as simply another alternative demodulator. The DRM Demodulator/Decoder then appears fully
integrated within the receiver front panel:




The DRM Demodulator/Decoder panel consists of the following main parts:

   Spectrum scope, which shows the real-time spectrum of the received signal
   Demodulator/Decoder status, which indicates the progress status of the main stages of the demodulation/decoding
process
   Services display, which shows the various DRM "services", making it possible for the user to select a service
   Text message window, which shows a decoded text message, if it exists in the DRM transmission
   Notch filter, which may improve reception with DRM signals damaged by interference
   Recorder/player, which can record audio in a variety of formats, as well as the intermediate frequency signal
   Playlist, which makes it possible to easily and quickly select previously recorded files
