STL
STL, which stands for Studio-to-Transmitter Link, is a crucial system used in radio broadcasting that connects a radio station's main studio to its broadcast transmitter, which is often located at a different site (like a hilltop or tower). Think of it as a reliable pipeline that carries the radio station's audio content from where it's created to where it's actually broadcast to listeners. This system is essential because radio stations usually create their content in convenient urban locations but need their transmitters in elevated areas for better coverage.
