A method for finding the evolving Radio Luminosity Function (RLF) for radio galaxies and quasars is described. The RLF describes the co-moving density of objects as a function of intrinsic luminosity and epoch. An equation for determining the function exactly is derived, based on a number of recent radio surveys. Selection effects are expressed simply in terms of total flux, since there is no contamination from objects in the Galaxy. A maximum likelihood procedure was used to fit the data to two different data sets. The solution to the equation is presented in the form of graphs describing the redshift constraints of two spectral types. It is shown that both spectral types exhibited behavior similar to that reported for optically-selected quasars in the third redshift.
