The DRD (Digital Radio Decoder) uses an AMBE+2 vocoder for voice decoding. The WiNRADiO DRD Demodulator/Decoder plugin is used to receive digital transmissions with a codec employed to produce decoded audio from the transmission (this device provides the necessary codecs).

The WiNRADiO DRD makes it possible to demodulate, decode, analyze and monitor DMR/MOTOTRBO, dPMR, D-STAR and NXDN digital signals (excluding encrypted types) using the WiNRADiO WR-G39DDC and WR-G315 series of receivers. The screen shot here shows the G39DDC version of plugin where a separate window is spawned. With the G315 version, the plugin is embedded within the main application window. The decoder supports the voice traffic on both inbound and outbound channels, displays digital transmission parameters and supports a secondary transmission channel if 2 TDMA channels on a single frequency are being transmitted.
