Many colleges and universities, middle schools and even primary schools have adopted campus FM broadcasting to broadcast English programs or other programs. The frequency range is usually between 76-87 Mhz, that is to say, it can be received by ordinary TV backup radio. Nowadays, some FM radios directly extend the frequency to 76-108 Mhz, which can meet the needs of listening to campus radio.
