When we were kids on the ranch, we would hook a wire to an isolated top wire of a barbed wire fence five miles long. Used to get Wolfman Jack when he was broadcasting illegal stuff underground from Mexico...
“Radio at night...” :)
I remember my brother hooking up his first crystal radio to a radiator - voices coming out of the ‘air’.
Of course we had TV by then, for years; but it wasn’t nearly as fascinating or magical as hearing that home-made radio...
