Design and Application of a Multi-frequency Backup System for Remote-controlled Single FM Transmitter
Based on the actual need to ensure safe broadcasting at high-altitude wireless transmission stations,a solution for remote control of multi-frequency backup for a single FM transmitter is proposed.By configuring four stereo FM broadcast exciters on the basis of one FM broadcast transmitter power amplifier and one set of antennas,the solution enables the backup broadcast of four FM broadcast programs using a single FM transmitter.The content and frequency of the backup transmission equipment can be remotely(locally)controlled,thereby enhancing the level of safety in broadcast assurance.
