For the high-frequency transmission of radio broadcast signals in the terrestrial domain, FM transmitters are used, which are modulated with the program signal produced in the studio. The delivery of this modulation signal to the exposed transmitter sites is carried out via a variety of paths (wired links, satellite reception, microwave radio links, etc.) and is implemented redundantly due to the high availability requirements. The FM modulation input rack is installed upstream of the FM transmitter and, in the interest of secure and high-quality broadcasting, automatically selects the optimal modulation path. Each FM program to be transmitted is assigned its own dedicated FM modulation input rack.
