SDR–, developed by [Julian Haag], enables software-defined radios to be configured through a modular, synthesizer-like interface. Users can add blocks such as a radio, demodulator, and speaker, and route signals using connection cables.
The program includes various decoders and tools:
- ADS-B
- POCSAG
- SSTV
- DAB
- RDS
- Passive radar
- Direction finding
Files are published on GitHub.
Why it matters
For users who want to handle different radio signals in a single working environment, SDR– offers an approach based on creating a visual flow instead of switching between separate tools. This structure provides a framework that makes it possible to experiment within the same project not only with decoding broadcasts but also with areas of signal analysis such as passive radar and direction finding. Options such as ADS-B, POCSAG, SSTV, DAB, and RDS show that the tool appeals to communities interested in different types of communications and broadcasts. Publishing the code on GitHub allows users to examine how the project works, while leaving open the question of how the tool’s scope and supported functions will take shape over time.
