ExpertSDR3 is a next-generation software suite engineered to provide a powerful, intuitive interface for modern SDRs. Built on a high-performance, cross-platform architecture, it delivers a professional command centre experience featuring high-fidelity audio, lightning-fast spectrum visualisation, and advanced signal processing.

While ExpertSDR3 is a world-class local controller, its true power is unlocked as the flagship component of the Expert Remote System (ERS). This comprehensive, software-defined environment allows you to bridge the gap between the radio and operator, placing the full capability of a high-end radio shack in your hands – anywhere in the world.

Note: External link to the manufacturer’s ExpertSDR3 download page, where you can choose Windows, Linux, and macOS versions of ExpertSDR3 and ExpertStarter. ExpertStarter is also available for ARM64-based devices such as the Raspberry Pi.

The SunSDR2 PRO is extremely sensitive with performance similar to ANAN-100. With the 10 dB preamp turned on you can expect MDS figures better than -131 dBm and up to -136 dBm on some bands.  On the 2m band I could hear a signal at -140 dBm which is exceptional. This would make the radio a real contender for weak signal work on the 2m band.
