"I have also been a radio nerd of sorts since I was a little kid. I still love to find faraway broadcasts late at night. When I am in Central Washington camping, I have picked up stations off the "skip," from as far away as New Mexico and Texas. The "skip" refers to a radio signal bouncing off, unimpeded, the top part of our atmosphere and traveling greater distances because of it. The area where the signals bounce off this ionosphere is higher at night, allowing them to travel even farther."
Now that is a radio nerd (my kind of people). You just don't read that sort of thing very much anymore.
