Many thanks to SWLing Post<\/em> contributor, Andrew, who writes:<\/p>\n

Not kidding, a friend told me that NSA released a bunch of software to open source, the main list being here:<\/p>\n

https:\/\/code.nsa.gov\/<\/a><\/p>\n

\"\"<\/a>While looking at the list of projects on that page, halfway down the page, I found a project called “RedHawk” which is described as:<\/p>\n

“A software-defined radio (SDR) framework designed to support the development, deployment, and management of real-time software radio applications.”<\/strong><\/p>\n

Now, being curious I opened the github link:<\/p>\n

https:\/\/github.com\/redhawksdr<\/a><\/p>\n

[It] contains quite a number of subprojects, modules and other stuff, then I checked the main “RedHawk” project:<\/p>\n

https:\/\/github.com\/RedhawkSDR\/redhawk<\/a><\/p>\n

Here’s the documentation:<\/p>\n

https:\/\/redhawksdr.github.io\/Documentation\/index.html<\/a><\/p>\n

It seems really interesting; apparently it allows to define a wealth of processing stages (e.g. filters, converters…) and connect them to process signals coming from an SDR; I think it may be a very interesting and useful tool to fiddle\/experiment with SDR receivers, if I’m not wrong it may allow to push an SDR to the limits, improving its performance, and may also be useful to write SDR software!<\/p><\/blockquote>\n

Fascinating! Thank you for the tip, Andrew!<\/p>\n

Post Readers:<\/em><\/strong>\u00a0It appears this project has been in the public domain for a little while. Please comment if you’ve tried implementing RedHawk in your SDR system!<\/p>\n
