Shortwave Radio

Shortwave radio refers to radio waves with frequencies between 3 and 30 megahertz. These waves can travel long distances, often bouncing off the ionosphere, allowing broadcasts to reach far-off places. It is commonly used for international communication, broadcasting news, and emergency messages. Shortwave radios can pick up signals from around the world, making them popular among hobbyists, travelers, and those in remote areas. The technology is especially valuable in situations where other forms of communication may fail, as it can operate independently of the internet or local infrastructure.
