Contribute a Node

Help us by setting up a node to stream your local radio frequencies. Your contribution ensures more people have access to real-time emergency information.

General Information

Volunteer hosts will receive free access to all the scanner feeds they provide. Audio from your setup is streamed using the open-source software Rdio-Scanner, ensuring high-quality transmission.

Each county with an available stream is assigned a dedicated subdomain (e.g., subdomain.tnscanner.com) for easy access and sharing. The audio is sent to our ingest servers, hosted on our main infrastructure, where it is processed and linked. You'll receive public URLs for your streams, making it simple to monitor and share local frequencies with your community.
