We present qualitative models for the non-thermal radio emission of single O stars, in terms of synchrotron emission by wind-embedded shocks. When we include the fact that shocks weaken as they move out with the wind, as predicted by time-dependent hydrodynamical simulations, these models produce a radio spectrum with a positive slope (as function of frequency), in contradiction with the observed negative slope. We conclude that non-thermal radio emission cannot originate from wind-embedded shocks, and is likely to be caused by a wind-colliding shock. A radio light curve analysis of two non-thermal O stars that are generally assumed to be single supports this conclusion.
