Shortwave Radio: A Fascinating World of Strange Voices and Messages

Shortwave radio, often associated with a bygone era, continues to be a vibrant medium for communication and entertainment. Andrew, a computer engineer from Estonia, shares his passion for shortwave radio and its ability to broadcast music and messages across vast distances. Shortwave signals can travel thousands of miles and are used for vital communication in aviation, maritime traffic control, and government-sponsored transmissions. One intriguing aspect of shortwave radio is the presence of numbers stations, which broadcast mysterious messages for secret communication. These stations play sets of numbers and letters that are decoded by agents using one-time pads. While their purpose remains largely unknown, numbers stations are believed to have been used by intelligence agencies to send top-secret messages to spies around the world.
