Radio RSA

Radio RSA existed from 1966 until 1992 and was based in Johannesburg, South Africa.  The government-run, pro-apartheid, external voice of the country broadcast into Europe, North America and the rest of Africa via shortwave.  Although their stated goal was "to present the nation in a positive and correct image," much of the station's role was to promote white power and black subservience.  The station's interval signal, which marked the beginning of each broadcast, was a traditional folk song combined with the call of the native Bokmakierie bird which appears on the above stickers.

Following the end of the apartheid government Radio RSA was renamed Channel Africa.
