Winrad and its forks (HDSDR & WRplus) are software radio interfaces that run on Windows. They support a number of SDRs as input sources (known as ExtIO plugins). There was previously one for the USRP, however I decided to write a new one with UHD and legacy support, and much more (e.g. remote control and streaming over a LAN).

For instructions, help and more technical information, please visit the wiki page.

You can download this plugin, with BorIP, on the download page.
