Field notes

Ondula presents a physical RF receiving node in Monterrey as a public, queryable measurement service. Its interface separates scheduled observations from on-demand requests, exposes an MCP endpoint for external clients, and provides job references for queued work. The page says results include signed receipts and derived artifacts rather than raw IQ data. It also defines operational boundaries: two measurements per IP every 120 seconds, an envelope-capture ceiling of 2.437 GHz, and no RF transmission from the node.
