What's All This Open-Source Stuff About?
In recent years, many open-source projects have started, which has fueled the Open Source Hardware Association (www.oshwa.org). We believe the largest open-source hardware project is www.OpenCompute.org which was started by Facebook, and many smaller how-to design projects from 3D printers to one IC radios. Open-source software projects like the many flavors of Linux, Apache, OpenOffice, Android, and thousand others less well known have existed for decades. Designers across the globe have created open-source projects with the hope others can help improve their designs, create more improved hardware based upon those designs, and eventually drive the price of that hardware down to commodity prices, as done in the computer field. We hope the open-source concept grows in the LMR field, providing ever declining prices for all users, whether hams, businesses, or for public safety.
