I'm trying to find a solution for organizing recordings produced by SDRTrunk on the Linux platform. I decided to try Rdio-scanner, and I have it working with one system using the API method (not Dirwatch). I have two other systems that I monitor and want to add them to Rdio, however I am unclear about setting the API key for additional systems: do I reuse the API key that I created for the first system; or do I create unique API keys for each system that I want to monitor?
