    Abstract: A method and associated circuitry for retuning a tuning frequency of the tuning circuitry (422) of a radio receiver (400) to a frequency channel of a set of frequency channels. The tuning frequency of the tuning circuitry is returned when the tuning circuitry (422) is initially communication signal (412) transmitted by a transmitter of a most-desired network of transmitters is detected by the radio receiver (400) when the receiver (400) is retuned, then the receiver (400) clamps to the transmitter of the most-desired network of transmitters.

    Abstract: A radio transceiver (119) including a transmitter (111), a receiver (107), and a controller (113). The controller (113) creates a fixed period reference signal (201) and a second reference signal (203) which has a variable delay in time from the fixed period reference signal (201). In addition the controller (113) creates a plurality of control signals used to control parts of the transceiver (119) and which are time dependant upon the second reference signal 203). Therefore, the adjusting of the variable delay of the second signal subsequently adjusts the plurality of control signals.
