Some years ago a fellow amateur radio operator obtained permission from the powers that be to set up a beacon for a weekend in order to experiment with 'meteor bounce' signals. I agreed to be one of his listeners and to log any signals received. Whilst signals in the hours I listened were very short (I'm talking less than a second for the vast majority of them), I was surprised at the number of them. At a guess I'd say that most would have been invisible even had it been night time. This experiment took place at approx. 144.2 MHz.
Incidentally, as it might interest some, the arrangements between us both were made using aircraft to reflect our voice signals between our equipment (me in the Blue Mountains, near Sydney, and he in Brisbane's environs).
Thanks for the links and the memories, Mr Subatomic.
