A method performed by an apparatus (110) is disclosed. The method comprises initiating a generation of a digital signal (195), wherein, for at least one time frame, the digital signal comprises a plurality of radio program signals (N-X, RA-X, RB-X). Therein the plurality of radio program signals (N-X, RA-X, RB-X) comprises a first radio program signal (RA-X), which is a regional radio program signal for a first region (A), and a second radio program signal (N-X), which is a supra-regional radio program signal. The method further comprises initiating a transmission of the digital signal (195) by a head-end transmitter (120) towards a plurality of back-end transmitters (150, 162, 172), the plurality of back-end transmitters (150, 162, 172) including a first frequency modulation, FM, back-end transmitter (150) configured to broadcast a radio program in the first region (A). Further disclosed is another method performed by an apparatus (130). The method comprises obtaining such a digital signal (195). It further comprises initiating an FM transmission, for at least one time frame, of a first regional radio program encoded in the first radio program signal (RA-X) by an FM back-end transmitter (150) configured to broadcast a radio program in the first region (A). Further disclosed are computer programs comprising program code for performing the above methods, apparatuses (110, 130) configured to perform the above methods and a system (100) comprising these apparatuses (110, 130).
