I first sent this into Cecil, but he obviously has better things to do. A friend recently showed me that if she presses her car alarm clicker against her chin, it increases the range of her clicker. I tried it with mine, and found I needed to press it against my cheek bone to work. I have a beard so maybe that caused a problem. Nevertheless, when I press my car alarm clicker against my cheek bone, I get at least a ten-fold increase in range. I can turn my car alarm on and off from clear across the parking garage. Try it yourself, you’ll see that it works. What is happening here? Am I amplifying the signal somehow? * * * Robert ---

[crazy guess]Just maybe you are inadvertently providing some sort of ambient signal shield for your clicker or in the alternative a makeshift floating ground of some sort. Maybe it has something to do with resonant frequencies and/or radio frequency signal wave length variables.[/crazy guess] * * * “What’s right is only half of what’s wrong and I want a short-haired girl Who sometimes wears it twice as long” George Harrison - _Old Brown Shoe_ ---

Your whole body is acting as a transmitting antenna when you do that. You observe the same effect when you only get a good TV picture while physically fiddling with the rabbit ears. As soon as you let go of them your reception deminishes.
