- Signal Capture 7C-2024-03-17 (Parts 1-6)
Unprocessed 6-hour capture from Site 7-C, March 2024
Total duration: 6:14:33 | 4.5 kHz baseline | 6 separate files
Recorded during routine monitoring operations at Site 7-C on March 17, 2024, this capture represents a continuous six-hour observation period of the 4.5 kHz carrier frequency. The recording has been divided into six one-hour segments for archival purposes. All files are unprocessed WAV format at 48 kHz sampling rate. Equipment used: Keysight N9030B PXA Spectrum Analyzer (SA-01), direct output to Data Logger (DL-03). Weather conditions: overcast, light wind, temperature 8°C. No significant anomalies detected during capture window, though minor frequency drift was observed between 14:22 and 14:47 UTC (see observation log 7C-2024-03-17-OL for details).
- North Array Ambient Recording (Parts 1-4)
4-hour baseline capture, October 2023
Duration: 4:02:18 | Full spectrum | 4 separate files
Full-spectrum ambient environmental recording captured at the North Array receiver installation site in October 2023. This baseline capture was conducted as part of initial site commissioning to document background noise profiles and establish reference data for future anomaly detection. Recording includes natural environmental sounds, equipment operation signatures, and atmospheric conditions typical of the site location. Files are archived in four one-hour segments. This baseline is referenced in Standard Operating Procedures (SRN-SOP-2024-Rev3) as the primary comparison dataset for subsequent field recordings.
