sdrtrunk: A Cross-Platform SDR Tool for Trunked Radio Protocols
Welcome to the world of Software Defined Radio (SDR) with sdrtrunk, a powerful Java application designed to decode, monitor, record, and stream trunked mobile and related radio protocols. Whether you’re a hobbyist or a professional, sdrtrunk simplifies working with SDR hardware to unlock the potential of trunked radio systems.
📌 What’s New?
The sdrtrunk project is continuously evolving, with recent updates including:
- JDK 25 & Gradle 9.2: Enhanced compatibility and performance.
- USB4Java Fork: Updated libraries for better macOS support (Tahoe 26.1+).
- JMBE Creator Support: macOS x86-64 compatibility for advanced features.
- APCO25 Phase II Decoder: Improved decoding capabilities for modern protocols.
⚠️ macOS Tahoe 26.1 Compatibility Fix
A recent change in macOS Tahoe 26.x caused sdrtrunk to fail on launch. Here’s how to fix it:
Step-by-Step Solution:
- Install libusb from HEAD:
brew install libusb --HEAD- Create Directories:
sudo mkdir -p /opt/local/lib- Link the Library:
Find your installed libusb path (e.g.,/opt/homebrew/Cellar/libusb/HEAD-9ceaa52/lib/libusb-1.0.0.dylib) and create a symbolic link:
sudo ln -s /opt/homebrew/Cellar/libusb/HEAD-9ceaa52/lib/libusb-1.0.0.dylib /opt/local/lib/libusb-1.0.0.dylib- Use Nightly Builds: For the latest fixes, download the nightly build and ensure you back up your playlists.
