Conditions Shortwave and VHF 

Shortwave refers to a range of radio frequencies that are used for long-distance communication. Shortwave signals can travel vast distances by bouncing off the Earth's ionosphere, allowing them to reach different parts of the world. This characteristic makes shortwave radio useful for international broadcasting, emergency communications, amateur radio, and utility services. Shortwave radio receivers are designed to tune in to these frequencies and listen to broadcasts from around the globe.
