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, WR-G69DDC and WR-G315 series of receivers.
The adjacent screenshot shows the WR-G39DDC and WR-G69DDC receiver application, where a separate window is spawned. With the WR-G315 receiver, the decoder panel 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.
