What would I hear on a 1Hz AM reciever? Nothing. Even were such a thing possible, and you converted the 1Hz RF carrier to audio, the human ear can't hear that low anyway. Ed |

If you follow the rule of thumb that the signal bandwidth should be less
than the carrier -- nothing. Your signal would be less than 1Hz, and you can't hear sounds that low. If you modulate your 1Hz "carrier" with something audable you'd hear your original signal fading in and out at a 2Hz rate. I imagine that a geo- or astro-physicist might be interested in electromagnetic effects below 1Hz, though. "Curious" wrote in message om... What would I hear on a 1Hz AM reciever? |

What would I hear on a 1Hz AM reciever?
========================= Nothing. Far too low below human audibility. Even elephants can't get down that low. |

OK. I'm going to reveal my secret idea, so PLEASE don't tell anyone.
Take one old farm silo. Fit it with an old sweat 16 speaker system, or something big-- at it's bottom. You'll need a big amp as well. Open the top. This bugger should resonate somewhere around... Lets see...silo...about 30 feet tall...well about half the frequency of 16' pipe organ pipes. In the sub bass range. Oh yea, make sure the silo is tall enough to get below the audible range. Find another the same size or several around the country. There you have it. Sub audible CW. How far do you think it'll travel. I suspect you may need some elephant repellant. No, it IS to keep elephants away. But, you say. There aren't any elephants anywhere on this continent. SEE! it works! 73 -- Steve N, K,9;d, c. i My email has no u's. "Curious" wrote in message om...
