**SDRangel** is an Open Source Qt5 / OpenGL 3.0+ (Linux) SDR and signal analyzer frontend to various hardware.
**SDRangel** is an Open Source Qt5 / OpenGL 3.0+ SDR and signal analyzer frontend to various hardware.
**Check the discussion group** [here](https://groups.io/g/sdrangel)
**⚠ Warning**: Windows distribution is provided as a by product of the Qt toolchain. The platform of choice to run SDRangel is definitely Linux. You are encouraged to use the group to seek help from other Windows users but the author cannot give help or any support for problems related to running the software on Windows. Issues specific to Windows problems opened on Github will be closed systematically. Windows distribution may be discontinued in the future.
**⚠ Warning**: Windows distribution is discontinued at version 4.0.0. This is the last version with a Windows build.

Although such serial devices work with a serial interface at 400 kb in practice maybe for other reasons they are capable of handling only one conversation at a time. The software will allocate the device dynamically to a conversation with an inactivity timeout of 1 second so that conversations do not get interrupted constantly making the audio output too choppy. In practice you will have to have as many devices connected to your system as the number of conversations you would like to be handled in parallel.
Note that this is not supported in Windows because of trouble with COM port support (contributors welcome!).
Alternatively you can use [mbelib](https://github.com/szechyjs/mbelib) but mbelib comes with some copyright issues (see next). If you have mbelib installed in a custom location, say `/opt/install/mbelib` you will need to add these defines to the cmake command: `-DLIBMBE_INCLUDE_DIR=/opt/install/mbelib/include -DLIBMBE_LIBRARY=/opt/install/mbelib/lib/libmbe.so`
Possible copyright issues apart (see next) the audio quality with the DVSI AMBE chip is much better.
