Abstract
An active broadcast survey system ( ) is configured to identify radio stations ( ) to which tuners ( ) are tuned. The tuners ( ) have local oscillator signals ( ) emitted therefrom. The survey system ( ) employs a method ( ) that includes generating and broadcasting a survey signal ( ) that is a one of the local oscillator signals ( ) modified to incorporate a signal identifier ( ). The method ( ) further includes detecting a harmonic ( ) of the fundamental frequency ( ) of the local oscillator signal ( ) within a received broadcast signal ( ) and determining that one of the tuners ( ) is tuned to one of the radio stations ( ) when the detected harmonic ( ) includes the signal identifier ( ). The survey system ( ) also employs a method ( ) for active tuning of the system ( ), and another method ( ) for providing short range communication with a remote transceiver ( ) to facilitate uploading and downloading of system settings and data.
