We present the results of an 8.4 GHz VLA survey of the CfA Seyferts. W
e find that the luminosity functions for Seyfert ls and 29 are essenti
ally identical, but that the type 2 objects are more likely to contain
extended radio structures. This seems to be consistent with unified m
odels for Seyferts, in which the differences between the two classes a
re largely due to orientation effects.
