Some of NoraSector's code is available at GitHub.
Turbine is NoraSector's SDR software. It was purpose-built for NoraSector's use case, namely capturing and streaming all frequencies of a trunked radio system concurrently. Unlike most SDR software, it's written entirely in Go. Go's concurrency model was a natural fit for the problem, which at its core is doing many concurrent DSP operations on a single byte stream from a SDR.
Turbine was intended to be run as a server-side application, i.e., there is no UI for configuration. It can run in a Docker container. It does not bond multiple SDRs together. Its intention is to be run with a single, high sample rate SDR on a powerful computer. NoraSector's production radio runs on a dedicated Core i7-11700k and uses a HackRF one. Turbine currently only supports the HackRF one but should be easily adapted to any SDR that can output IQ samples.
Turbine features a built-in visualization web server to view graphs of each stage of the DSP pipeline for every frequency it's tuned to.
