 From version 3 transmission or signal generation is supported for BladeRF and HackRF (since version 3.1) using a sample sink plugin. These plugins are:
 
-  - [BladeRF output plugin](https://github.com/f4exb/sdrangel/tree/dev/plugins/samplesink/bladerfoutput) Linux only

   - [File output or file sink plugin](https://github.com/f4exb/sdrangel/tree/dev/plugins/samplesink/filesink)
 
-Transmision with "real" devices (BladeRF and HackRF) is supported in Linux versions only. Be also aware that this is **very experimental**. Code is not very efficient so you may experience **performance problems**. Contributions are welcome to enhance the transmission side.
