Doug,

I have to laugh. I too built a parabolic reflector out of an old circular snow disc, sled, as a kid. I think I paid 75 cents for the plans. Kind of like X-Ray specs. I still don't understand why clear audio transmissions of environmental activity can't be achieved on Mars rovers for instance. It seems that radio technology would be simple to incorporate into the otherwise complex deal. Is my question really so naive? 

Regards,
Bill


-------------- Original message from MexicoDoug at aol.com: -------------- Hola, Stan would seem completely right to me.  I just have one question, though.  I remember being fascinated with the idea of building a supersensitive microphone as a kid, the kind that could hear a bird at 1000 feet and a whisper in the next room, etc.  I actually did, though my inexperienced use of ferric chloride produced something that best picked up breathing that sounded like scuba diving sounds.

One claim -since I wasn't able to make a good parabolic antenna- and they were not really available at that time like now, that always had me dream about reaching out to the universe was the supposed ability of the microphone to pick up "sounds" from Jupiter.  Is there anything to this, and if there is, what Jovian "sound" is actually picked up from earth's surface?

Gracias
Doug
