Fobos SDR support in SDRangel has been expanded: following the introduction of native support on Windows, Fobos SDR is now available as a native SDRangel source on Linux as well. Native Fobos SDR support for Linux was officially added to SDRangel in version v7.27.0. The SDRangel release notes specifically mention that the native Fobos SDR source plugin was enabled for Linux.

Fobos SDR supports operation with SDR++, but the level of support depends on which module (plugin) is used. To get the full functionality of Fobos SDR, we recommend using the SDR++ Plugin from RigExpert, which was specifically developed for Fobos SDR and supports all device capabilities.
