Abstract: The invention discloses a method for operating a communication terminal comprising a receiver chain (EK) with at least one receiver component (RXD) and with an amplifier device (LNA) connected upstream thereof for receiving broadcast radio signals transmitted in first time periods in a predetermined frequency band, and also a transmission device (SEM) for transmitting radio signals. The method has the following steps. First of all, the noise occurring upon transmission of the radio signals in the frequency band of the receiver chain is measured in the receiver chain and then the gain of the amplifier device is set on the basis of the measured noise such that a maximum signal level on the receiver component is not exceeded.
