  The CoNFIG (Combined NVSS-FIRST Galaxies) sample is a new sample of 274
bright radio sources at 1.4 GHz. It was defined by selecting all sources with
S_1.4GHz > 1.3 Jy from the NRAO-VLA Sky Survey (NVSS) in the North field of the
Faint Images of the Radio Sky at Twenty-cm (FIRST) survey. New radio
observations obtained with the VLA for 31 of the sources are presented. The
sample has complete FRI/FRII morphology identification; optical identifications
and redshifts are available for 80% and 89% of the sample respectively,
yielding a mean redshift of ~0.71. One of the goals of this survey is to get
better definitions of luminosity distributions and source counts of FRI/FRII
sources separately, in order to determine the evolution of the luminosity
function for each type of source. We present a preliminary analysis, showing
that these data are an important step towards examining various evolutionary
schemes for these objects and to confirm or correct the dual population unified
scheme for radio AGN. Improving our understanding of radio galaxy evolution
will give better insight into the role of AGN feedback in galaxy formation.
