Talking Around the World
For many Hams, the lure of talking to someone in a faraway place is the ultimate thrill of amateur radio. Hams call it "DX," which is an abbreviation for long-distance work. Using the ionosphere, 100 to 200 miles above the Earth's surface, to refract their signals long distances, Hams have long done pioneering work in understanding how radio waves behave, leading to more effective short-wave broadcasting stations, improved military communications, and better coverage for your local AM and FM broadcasters.
The fun comes in building and improving your station so that it can reach out farther, allowing you to talk to more and more places. You learn about building better antennas, find out which frequencies work best at different times of year, and even what microphone to use (Heil Sound's HC-4 element was specifically designed for DX work). And you learn a lot about people around the world, maybe even leading to an invitation to visit places like China, Russia, Argentina, Australia, or South Africa. You make friends fast through ham radio, and there's always a new friend to be found when you turn the radio on.
