Shout out to the early adopters currently powering SpectrumNet. We've hit 3,451 spectrum snapshots across our first 6 nodes in the US. The detail in these captures helps us identify real-world anomalies (1,553 so far). It’s amazing to see what community-driven data looks like.

The radio spectrum is an invisible landscape, and we’re just beginning to map it. With 6 active nodes, we've already logged 3,451 snapshots and 1,553 anomalies. We need more eyes on the airwaves to expand beyond the US. Plug in any SDR and help us build this open dataset.
