A model for a class of quasars and active galactic nuclei is proposed in which a shock around a massive black hole randomizes the infall kinetic energy of spherically accreting matter producing a nonthermal spectrum of high energy protons. It is suggested that these protons are responsible for the secondary production of the radio-emitting high energy electrons and also of high energy γ-rays. The correlation between radio and γ-ray emission implied by the model is in good agreement with observations of 3C 273.
