SMR was not very successful and was replaced by Radio SR which was the first South African radio station playing entirely music by black South African and American artists. Radio SR was an instant success and broadcast from the SMR studios and transmitters. Rob Vickers of LM Radio fame was the programme manager at Radio SR. When Issie Kirsh set up 702, he appointed Rob Vickers, Gary Edwards, Frank Sanders and Stan Katz, all of whom had worked on SMR / Radio SR as well as Clark McKay who had previously worked at LM Radio and Springbok Radio. John Berks who had spent time on Radio 5 and later Capital Radio 604 joined shortly thereafter. Cocky Two-Bull Tlhotlhalemaje, a jazz musician and broadcaster was the first black African to work on Radio 702. He helped to break down the barriers between the youth of all ethnic groups.
