A self-taught signals & electronics hacker from Helsinki spotted a curious pattern in an audio recording of a helicopter and figured out how to decode it...and what it meant.
Mystery signal from a helicopter http://www.windytan.com/2014/02/mystery-signal-from-helicopter.html Last night, YouTube suggested a video for me. It was a raw clip from a news helicopter filming a police chase in Kansas City, Missouri. I quickly noticed a weird interference in the audio, especially the left channel, and thought it must be caused by the chopper's engine. I turned up the volume and realized it's not interference at all, but a mysterious digital signal! And off we went again. -Tom _______________________________________________ Hardwarehacking mailing list [email protected] http://lists.blu.org/mailman/listinfo/hardwarehacking
