The common-wave broadcasting of radio programs is known in the art. Common-wave operation of radio transmitters allows the available transmission band width to be particularly well utilized, for example for national scale common-wave broadcasts. A new process now allows a stereo transmission channel to be divided into two mono transmission channels during radio broadcasts and to broadcast certain programs only through particular transmitters. Information concerning the division of the stereo transmission channel into two mono transmission channels is further broadcast over the entire common-wave transmission network. This information causes receivers tuned to this transmission channel to automatically switch to mono evaluation of the reception signal. On a regional level, information may also be broadcast concerning which of both mono transmission channels may be received. Alternatively, the receiver or user himself may select the mono transmission channel he wishes to receive. This process may be implemented with all common-wave broadcasting modes.
