%X A general equation for the extragalactic background intensity is derived for the general case of an isotropic homogeneous universe. The extragalactic radio spectrum depends critically on the thermal history of the universe and numerical results have been obtained for different possible models. A brief discussion is given on the conclusions drawn from the comparison of these results with the observed background spectrum.
