Recently an updated set of binaries and build scripts were posted for GNU Radio for Windows. GNU Radio is a graphical digital signal processing language that is compatible with many software defined radios such as the RTL-SDR. Normally it is used on Linux as the Windows builds have been known to be very buggy and difficult to install. However the latest update appears to make it easier to install. The changes were announced on the GNU Radio mailing list by Geof Nieboer, and he writes:
An updated set of windows binaries and build scripts have been posted. Quick summary:
1- Added gqrx to package
2- Patched 2 x issues which would cause the generic version to crash on non-AVX systems (one in volk, one in FFTW)
3- Added gr-newmod to packagePlus a number of improvements to make the scripts more robust.

To run GNU Radio for Windows you will need a 64-bit version of Windows 7/8/10. It appears that the installation is as easy as running the installer and waiting for it to download and install the 1.7 GB worth of files.
Also, over on his blog author designing on a juicy cup posted about how he’d been able to get the GNU Radio Windows binaries to run a ATSC HDTV decoder from a file recorded using an SDRplay RSP (ATSC is too wideband for an RTL-SDR to decode). ATSC is the digital TV standard used in North America, some parts of Central America and South Korea. He writes that one advantage to using GNU Radio on Windows is the ability to use a RAM drive for faster file processing.
