The Weak Signal Challenge - Decode and Win $100

superid writes "Several years ago while reading comp.dsp I found a link to The Weak Signal Challenge. On that page is a .wav file of a morse code signal bounced off the moon. The page author Mike Cook is offering $100 to the next person to successfully decode the morse code. Since I was the one who originally solved this, I promised Mike that I wouldn't divulge the answer or provide any clues. I can say thought that I didn't use anything special other than traditional signal processing techniques, octave, matlab, and patience. I think that overall I spent about 24 hours total sitting at my '486. I think it would be great to generate some interest in this. Maybe someone could come up with a novel solution and win $100!"

Who needs Matlab? I can hear the morse code beeps

I can clearly hear the morse code beeps. With some head phones (if I knew morse code) - I could decode this using only the world's most powerful real-time signal processing and pattern recognition device - the human brain.
