The LW, MW and SW band cover the range from 0.2 to 30 MHz. SW is especially interesting. Radio waves in the shortwave band can be reflected or refracted from a layer of electrically charged atoms in the atmosphere called the ionosphere.

The length of the antenna needs to agree with the length of the longest radio waves that you want to receive. Shortwave broadcasters use frequencies that are from about 50 to about 400 feet long, and an effective antenna needs to be at least one-fourth of that length — and one-half is much better.

It's a simple matter to measure and assemble a 22-foot piece of the line and then cut back one conductor on each side to the proper length for 10 meters. You can do the same thing for the 40/80-meter sections, but you can reduce the amount of open-wire line needed by splicing on a single wire for the 80-meter extension.DES encryption was developed by IBM and adopted by the U.S. government in 1977. Its 56-bit cipher was quite secure at its inception, but by the 1990s, the rapid advancement of computing power had made it possible to overcome DES through brute force — a computer could randomly guess the key in less than 24 hours.I listen to shortwave often!
