JIDE 3.6.18's LookAndFeelFactory contains compile-time \`instanceof com.sun.java.swing.plaf.windows.WindowsLookAndFeel\` checks in multiple methods, including a JIDE PropertyChangeListener that fires on every UIManager.setLookAndFeel call. On Linux and macOS JDKs the class is genuinely absent from java.desktop, so the JVM throws NoClassDefFoundError the first time JIDE's dispatch code is executed (during JFrame init and again from JideSplitPane.updateUI on each LAF change). Two complementary fixes: 1. Pass an explicit MetalLookAndFeel instance to the 3-arg installJideExtension(UIDefaults, LookAndFeel, int) overload so JIDE's Metal branch matches first and never falls through to the Windows branch in the normal install path. 2. Add a no-op stub class at com.sun.java.swing.plaf.windows.WindowsLookAndFeel so that the compile-time class reference resolves on non-Windows JDKs. The stub reports isSupportedLookAndFeel = false and is never instantiated - JIDE only uses it for instanceof comparisons against the active LAF, which always return false in our setup. On Windows JDKs the real class in java.desktop is loaded by the platform classloader and shadows this stub.
MacOS Tahoe 26.1 Users - Attention:
Changes to USB support in Tahoe version 26.x cause sdrtrunk to fail to launch. Do the following to install the latest libusb and create a symbolic link and then use the nightly build which includes an updated usb4java native library for Tahoe with ARM processor. There may still be issue(s) with MacOS accessing your USB SDR tuners.
brew install libusb --HEAD
cd /opt
sudo mkdir local
cd local
sudo mkdir lib
Next, find where brew installed the libusb library, for example: /opt/homebrew/Cellar/libusb/HEAD-9ceaa52/lib/libusb-1.0.0.dylib Note: the folder "HEAD-9ceaa52" is the version stamp for HEAD when you installed from it.
Finally, create a symbolic link from the installed library to the place where usb4java is expecting to find libusb (/opt/local/lib/libusb-1.0.0.dylib)
sudo ln -s /opt/homebrew/Cellar/libusb/HEAD-9ceaa52/lib/libusb-1.0.0.dylib /opt/local/lib/libusb-1.0.0.dylib

Download the Latest Release
All release versions of sdrtrunk are available from the releases tab.
- (alpha) These versions are under development feature previews and likely to contain bugs and unexpected behavior.
- (beta) These versions are currently being tested for bugs and functionality prior to final release.
- (final) These versions have been tested and are the current release version.
Download Nightly Software Build
The nightly release contains current builds of the software for all supported operating systems. This version of the software may contain bugs and may not run correctly. However, it let's you preview the most recent changes and fixes before the next software release. Always backup your playlist(s) before you use the nightly builds. Note: the nightly release is updated each time code changes are committed to the code base, so it's not really 'nightly' as much as it is 'current'.
