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!"
I actually tried the steak thing while doing Science at college level. It works.
We used a standard sized sirloin steak, in a glass bowl and a litre of normal Coke, left it covered in a normal 22 deg c room over the weekend, and on monday morning all that was left was some really icky coke and scum on the surface.
Sometimes it pays to try out some of this stuff, if you can. This was cheap and simple to try, so I tried it. Oh and all this was before I was even on the Internet.
