Compared to the level of the RF carrier of the adjacent frequency FM service or the FM service in the middle, the level of the plurality of RF carriers is selected to be sufficiently low in the sense of a signal to noise ratio that is sufficient for FM reception of the FM service or services. Moreover, the mentioned level is selected to be sufficiently high in the sense of noise immunity against more remote FM services which fall into the frequency range or frequency gap intended for the transmission of the plurality of RF carriers. The data stream modulating the RF carriers is provided with increased error protection in the sense of providing sufficient noise immunity against the adjacent frequency FM service or services or the FM service or services in the middle.
