An apparatus and a method for automatically establishing a new wireless link when the original wireless link between the apparatus and a commercially available FM radio receiver is interfered by other signal sources and reception conditions become poor, thereby eliminating the need to manually configure both the target FM radio receiver and the apparatus to a suitable FM frequency. The apparatus receives an audio signal, modulates and transmits the audio signal to the target FM radio receiver over a selected frequency, scans an FM spectrum for an alternative frequency, transmits an Radio Data System compatible command and a forcible switching signal to configure the target FM radio receiver to tune to the alternative frequency when signal quality of the received signal deteriorate sufficiently. |
