Abstract
The influence of the character of a numerical method used in the derivation of the evolution function of flat spectrum radio sources on the value of the redshift cut-off has been considered. An attempt has been made to apply to radio sources the general approach to the cosmological evolution based on the conservation equation. The discussion of two kinds of solutions of this equation approximating the numerical results of two methods: the fully free-form one and the method assuming pure density evolution of the most luminous sources leads to the conclusion that the general assumptions required by the latter may be responsible for shifting the value of the redshift cut-off to higher values ofz.
