Patent ID: 8315587

Claim:
An integrated circuit (IC) comprising: a single chip integrated circuit radio receiver including: an analog front end having an amplifier to receive a radio frequency (RF) signal and a mixer to downconvert the RF signal to a baseband signal; a demodulator to receive the baseband signal and obtain an audio signal therefrom; and a controller to receive a control signal based on and corresponding to a level of a single potentiometer coupled to the IC, wherein the single potentiometer is coupled to a manual tuning wheel of a radio including the IC, the mechanical tuning wheel to be manually adjusted by a user to tune to a radio channel, the single potentiometer to couple between a reference voltage and a ground potential, the controller to control a local oscillator coupled to the mixer responsive to the control signal, the controller to further control a pre-selection capacitance responsive to a ping signal transmitted from and received and processed by an antenna coupled to the single chip integrated circuit radio receiver, wherein the controller is to cause transmission of the ping signal to enable the controller to determine a frequency offset between the transmitted ping signal and the received ping signal.
