The present invention is for a high quality digital FM radio system that utilizes the subcarrier band to generate digital audio signals. The hybrid FM radio system utilizes the subcarrier band to transmit the digital FM signals that are synchronized to the analog FM signals.

The receiver may switch between the traditional analog signal and the higher quality digital signal automatically to present the best possible audio to the user.
