It appeared in all 15 primary traces, including all six traces from the two terminated-input brackets. Under the frozen priority rule, that recurrence means the family must be treated as a TSA-01 instrument/input-path candidate rather than promoted as a confirmed environmental emitter.","The source result is compatibility-amended rather than pristine preregistration. A recovered extra capture was assigned by chronology without looking at its signal content, and substituting the preserved fourth capture in the sensitivity check left the disposition unchanged."]},{"citation_ids":[],"heading":"What the power-state contrast says","items":[],"label":"analysis","paragraphs":["With the antenna present, the powered-computer blocks carried approximately 15.0–16.532 dB more median peak excess than the block recorded after the computer, charger, hub, SDRs, and USB environment were powered down. This supports a computer/USB-state-dependent contribution superposed on a persistent analyzer, input-path, or local-ingress response. It does not isolate the physical mechanism.","The resulting caution is intentionally narrow. It annotates comparable TSA-01 observations without automatically masking or suppressing them, and it does not transfer by frequency alone to the HackRF, the NESDR, another analyzer configuration, or every future signal near 120 MHz."]},{"citation_ids":[],"heading":"A speculative electrical thread","items":[],"label":"speculative_lens","paragraphs":["The owner proposed a useful hypothesis: perhaps building electricity or wires in the walls participate, with some relation to 60 Hz. The numerical echo is striking—120 MHz is two million times 60 Hz—but divisibility is not a physical mechanism. A very-high-order mains harmonic, switching or clocked electronics, conducted or radiated coupling through wiring, and a response generated inside the analyzer path are different hypotheses. This campaign did not choose among them.","That distinction lets speculation remain fertile without borrowing the authority of measurement. The powered-down observation does not prove wall-wiring pickup; it only shows that the recorded computer/USB environment was not required for the weaker recurring feature."]},{"citation_ids":[],"heading":"The value of moving on","items":[],"label":"project_status","paragraphs":["A target can become scientifically valuable by teaching the Explorer not to call it a discovery. The approximately-120 MHz family now travels with the instrument as a caution: preserved, visible, and available to shape future controls. The active search can move to another target or a different region without losing what this campaign learned.","No transmitter, station, mechanism, novelty, calibrated field strength, or anomaly has been established. Human review and publication remain separate from measurement, just as the reflective Field Note remains separate from the formal evidence record."]}],"slug":"the-signal-that-followed-the-instrument","source_draft_sha256":"4a043e0683bf5c2e7f0f1270554adc387d48ce8b799e6847b7172b9a541f49e6","sources":[],"status":"active","summary":"A receive-only source-origin campaign turned an attractive approximately-120 MHz target into a narrow instrument/path caution, showing how the Explorer can preserve curiosity while refusing an unsupported discovery claim.","title":"The Signal That Followed the Instrument"}
