Shortwave broadcasting is a method of transmitting radio signals over long distances using shortwave radio frequencies, typically between 3 and 30 megahertz. This type of broadcasting can reach listeners far beyond the horizon, making it useful for international communication and reaching remote areas. The signals can bounce off the ionosphere, allowing them to travel thousands of miles. Shortwave radio is often used by governments, international organizations, and amateur radio operators to share news, information, and entertainment with audiences around the world, especially in regions where other forms of communication may be limited.
