Abstract

Apparatuses, circuits, and methods for receiving at least one radio signal in a radio controlled timing apparatus using a single timing source. The present invention advantageously eliminates the need to provide an additional timing source to receive at least one radio signal, and therefore reduces the material cost and eliminates many engineering challenges.
