Singing Antennas

[Chuck K3FT]

The basic reason it 'sings' as it does it is that it has rectified the RF and produced a
signal in the audio range detectable to human ears. Just like the old situation of the
person who heard 'radio' coming out of their mouth, from the bedsprings in their bed,
etc. (Those instances are not fantasy, they have and do happen!) It's simple
rectification of the RF by the object being excited by the RF which reproduces it as
audio range emission.  Kinda spooky if you're not aware of the WHY or are suprised by
it.

Come to think of it.. would be a great gag to pull on an unsuspecting person. "Hey! Look
at what I can make my stuff do!" If nothing else, you will inspire them to look at you
in a very different light!
