  • Greetings all!

    We are Open Research Institute. We do open source digital radio work. We teach people digital signal processing and digital communications through open source work. We believe demonstrations are central to the process and lead very quickly to better understanding. All of our work is published on github and we have weekly project meetings on Zoom at 1000 US Pacific time. We have a website with a getting started link at [openresearch.institute/getting-s...](https://openresearch.institute/getting-started&10;&10;Thank) you to everyone helping us do ambitious things in radio! We appreciate your energy, time, and support very much.
