Since Afrikaans is one of South Africa's 11 official languages, the SABC is required to carry an Afrikaans-language service on both radio and television.

RSG broadcasts mostly on FM utilizing transmitters owned and operated by Sentech, the former signal distribution division of the SABC.

It was known as the "Afrikaanse Diens van die SAUK" (Afrikaans Service of the SABC) for many years until the Corporation restructured its entire radio portfolio in 1986 and it became known as "Radio Suid-Afrika".

RSG was a publisher of a chart of the best-selling CD albums in South Africa called SA Top 20.
