ABSTRACT:
A method and associated circuitry for acquiring a channel of a set of frequency channels by a radio receiver. The radio receiver scans selected control channels and measures the power levels of signals generated upon the respective ones of the control channels and stores values. An attempt to effectuate a communication link with a transmitter which transmits a data signal upon one of the control channels is only attempted if the measured power level on such control channel increases beyond a certain amount. The tuning frequency of the tuning circuitry can be retuned when the tuning circuitry is initially tuned to receive a communication signal transmitted by a transmitter of a less-than-most desired network of transmitters according to a second embodiment.
