Rob,

That is ZSC, Capetown Radio, a commercial maritime
coastal station. What you are hearing is a channel
marker, or idle signal, in one of the ARQ (teletype)
modes, SITOR, I think. If one knew their schedule,
traffic could be copied. (Assuming one had the proper
decoder.) A lot of these coastal stations still use
CW, such as IAR, RomeRadio, 7TF in Algeria, etc.
