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.

Changelog v0.5.0 beta3

1. Features:

• USB Tuner Management Redesign
• Enable/Disable Tuners on Startup
• Tuner Tab & Tuner Editors Redesign
• Embedded Java 18

2. Requirements:

• Windows x86 (64-bit)
• Linux x86/aarch64 (64-bit)
• OSX x86/aarch64 (64-bit)

Note: JMBE library must be manually downloaded/built for OSX aarch64 due to OSX sandboxing of downloaded code.
Note: Linux for arm-32 is NOT currently supported

3. Optional Requirements

JMBE version 1.0.9+ is required for decoding APCO25 Phase 1/2 and DMR digital audio on Linux and OSX aarch64.

Starting with Version 0.5.0 Alpha 2, you no longer have to install Java and compile the JMBE library. sdrtrunk now has integrated support for creating the JMBE library.

Legacy instructions for compiling the JMBE library are located at: https://github.com/DSheirer/sdrtrunk/wiki/JMBE
