SDR# | Free and Open-Source Software Defined Radio Receiver
Turn your computer into a software-defined radio receiver with SDR#, a free and open-source software package that supports many popular radios and can receive and demodulate various signals.
What is SDR#?
SDR# (pronounced SDR Sharp) is a popular free software package that enables software-defined radio (SDR) reception on Windows computers. It works with many common software-defined radios like the RTL-SDR dongle to open up a wide swath of radio frequency signals for listening and experimentation.
Some key features and capabilities of SDR# include:
- Supports a wide range of SDR hardware from companies like RTL-SDR and Airspy
- Has an intuitive user interface to control the SDR receiver parameters
- Demodulates and decodes signals like FM radio, police/emergency bands, pager messages, air traffic control comms, weather satellite images, and more
- Records signals to audio files for later playback and analysis
- Strong community support for plugins, tutorials, featured requests and troubleshooting in online forums
Hobbyists, ham radio operators, scanner enthusiasts and other technical users often use SDR# to explore wireless signals that were previously difficult for consumer hardware to access. It brings powerful SDR capabilities to commodity PCs and opens up many interesting signals in the radio frequency spectrum.
