Abstract
A system for receiving a radio signal representing a radio program comprises at least first and second radio receiver units. Each receiver unit receives the radio signal at a respective frequency and produces a respective radio program signal. All of the radio program signals represent the same radio program. A decoder decodes a control signal, such as an RDS signal, from each of the radio program signals. A control device processes the control signals to determine the delay between the radio program signals. The control device uses the delay information to modify a a variable delay in the signal path of at least one radio program signal until the radio program signals are synchronized. The synchronized radio program signals are combined, e.g., by fading the signals together, to produce a resultant radio program signal.
