Digital Radio Mondiale
The On-line Receiver contains DRM Decoder/Demodulator Plug-in.
This makes it possible for listeners to receive and listen to DRM transmissions. 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.
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
