The audio frequency response is restricted to 15 kHz, which is rather poor by modern standards. Talk and news, formats popular on AM are also heard on FM. A transmitting antenna, which sends out radio waves having the same frequency as the current supplied by the oscillator. An FM radio station broadcasts at a frequency of 100 MHz. How Does a Radio Station Work? AM/FM & Online Explained.
