Abstrakt: It is shown that inelastic proton collisions in extragalactic radio sources can account for their radio and ?-ray emissions. The proton Lorentz-factor ?p responsible for ?-ray emission is estimated to lie between 1.4 and 86. But for the radio emission (with ?e ~ 103-104) the estimated ?p values lie between 7 to 300. The estimates of total particle and magnetic energy for a typical radio source is in agreement with equipartition theory.
