About Us

The South Indian SDR User Group Story

The South Indian SDR User Group (SI-SDR-UG) was founded in January 2021, and is a community of people, from novices to experts, spanning industry, academia, and government, who are interested in the design and implementation of Software-Defined Radio (SDR) technology and systems. This includes such diverse areas such as RF, digital signal processing (DSP), wireless communications, operating systems, computer networking, software development and optimization, machine learning, and radio hardware. The mission of our community is to facilitate the exchange of ideas and enable greater collaboration within the SDR community in India. We host a regular technical workshops and gatherings, and we also run a dedicated Slack workspace for the community. We have a YouTube channel for recordings of past events, and a GitHub page for any relevant code. Our Twitter feed contains announcements about events and other news relevant to the community. We are not focused or tied to any one single software tool, hardware platform, commercial vendor, or specific technology. The SI-SDR-UG is non-profit, and the people on the organizing committee are all volunteers. We are based in Bangalore, but we invite people from all throughout India, as well as from outside India, to join our community. Please reach out to us on Slack or by email if you have any questions or comments. Thank you!
