WiNRADiO WA-0871 8-channel Digital Radio Decoder

The WiNRADiO WA-0871 8-channel Digital Radio Decoder is an extension unit that provides hardware codecs for up to 8 (optionally 16) channels of digital transmissions. All decoder channels are accessible over a single USB interface which is also used to power the decoder unit.

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 to decode up to 8 (optionally 16) digital transmissions simultaneously.

The WiNRADiO DRD can be used on systems with a single receiver, or up to 8 receivers. It is especially suitable for multichannel systems (like the WiNRADiO MS-8128).

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 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.

Under a multichannel environment, the WiNRADiO DRD comes with a transparent software management system that assigns free channels to the DRD upon request. When the channel is no longer used, the decoder can release it, making it available for another decoder or transmission.
