sdrtrunk

A cross-platform Java application for decoding, monitoring, recording, and streaming trunked mobile and related radio protocols using Software Defined Radios (SDR). SDRtrunk is an integrated application for demodulating radio signals and decoding trunked radio network protocols and some related radio signal formats. The application does NOT require a discriminator tapped scanner and it does NOT require the use of audio piping applications like Virtual Audio Cable. All connections between the tuner or sound card and the decoders are provided by the sdrtrunk application. SDRTrunk uses channel definitions to configure and set up each demodulation and decoder processing sequence. In order to successfully decode radio signals, each channel configuration requires:

• Source – specifies where to get the radio samples from (tuner or sound card)
• Decoder – which demodulator or decoder to use in processing the source samples

Each channel definition allows you to optionally configure:

• Aux Decoder – additional in-band audio digital signal protocol decoding
• Logging – log decoded messages or events
• Recording – record audio calls or digitized baseband samples

The SDRTrunk application is programmed in Java and can run on any computer where Java is supported for the operating system and where the computer hardware (processor/memory) is sufficient for the processing workload.
