Radio Main Control (RMC), Auckland Park:
The RMC is the main hub of all the RMC’s in the country.  Each SABC centre has a satellite RMC but the one in Johannesburg does the bulk of signal distributions.

• Distribution of SABC radio stations originating in Johannesburg like SAFM, RSG, R2000, 5Fm, MetroFm and Channel Africa and enabling add splits.
