In this video, I dive deep into one of the most intriguing pieces of UFO evidence ever captured — an audio recording allegedly broadcast over CB radio by an American police officer in 1981. The officer claimed to witness a UFO hovering over a river, and the eerie, otherworldly sound was captured on tape.🎧 I break down the audio using modern analysis tools — waveform, spectrogram, and frequency scans — to uncover whether this bizarre sound is mechanical, natural, or something else entirely.💡 You'll hear:The full original audio with no interruptionsA dissection of key frequencies including persistent tones at 465–475 Hz and 861 HzComparisons to known sources like engines, signal tones, and electromagnetic interferenceInsights into whether this aligns with classic UFO encounter patternsWhether you're a skeptic or a believer, this breakdown lets the evidence speak for itself.Full analysis breakdown of all the data in a nice tidy article can be found here: https://open.substack.com/pub/uapf/p/the-sound-of-a-ufo-1981-police-encounter?r=3avcjy&utm_medium=iosLinksIG https://www.instagram.com/uap_files/Website https://linktr.ee/uapfilesSUPPORT/DONATEIf you’re able, your support would be greatly appreciated 👇👇https://buymeacoffee.com/uapfiles#UFO #UFOsighting #UFOaudio #Paranormal #PoliceEncounter #1980sMystery #UnexplainedSounds #AudioAnalysis #UFOEvidence #CBRadio #sgtyokum #uapfiles #uapfilespodcast
