Abstract
When mixed modulation signal may be erroneously determined to be a signal intended to be received by a particular receiver the receiver checks whether prevailing received signal is a signal intended to be received by that receiver. When the received signal intended is other than a signal to be received, by that receiver the receiver turns off an antenna tuner to prevent impedance matching between the antenna side impedance and the radio section side impedance. When the received signal intended is a signal to be received, by that receiver the receiver turns on the antenna tuner to allow impedance matching between the two impedances.
