FACT: I was turned off from ham radio for over 2 years because of the impression that all ham operators can do is whine and cry amongst themselves on this message board. I applaude those who contribute by posting material that actually pertains to the topic. Thanks. I would like to see an experiment that would study how long a radio transmission could stay in the atmosphere bouncing around. Could it be possible that it remain there an extended period of time before bouncing back to earth?
