SWL (Shortwave Listener)

A Shortwave Listener (SWL) is someone who listens to radio broadcasts transmitted using high-frequency (HF) signals, typically between 3 and 30 MHz. These signals can travel long distances by bouncing off the Earth's ionosphere, allowing listeners to receive broadcasts from around the world without needing a subscription. SWLs enjoy exploring diverse programming such as news, music, cultural content, and even emergency communications. The practice requires a radio capable of tuning into shortwave frequencies and often involves identifying stations, understanding signal patterns, and sometimes recording or logging transmissions for personal interest or study.
