Initiating static analysis...
Frequency modulation detected at 12.3 GHz. The spectral profile aligns with previously decoded signals of unidentified origin. Distortion levels are marginal, suggesting proximity to interference-free zones. The transmission contains prominent pulsations of Fourier complexity.
Decoding sequence engaged...
Initial parameters indicate a duration of 47.3 seconds, with an encoding algorithm reminiscent of classical telegraphy. Data pack structure comprises segments: Header (8 bits), Timestamp (16 bits), Message payload (variable), Closure (Checksum, 8 bits).
Extracted message component:
"...causes of disappearing phenomena within atmospheric layers, obscured by light that cannot be quantified by conventional known measures, reaching towards optical invisibility thresholds."
Final observations: The return path analysis remains inconclusive. The lightbeam hypothesis appears linked to terrestrial anomalies documented as 'Shadow Echo’ events. Further dissemination halted pending authorization.
