As resolved by the VLA and MERLIN, the radio structures of Seyfert galaxies commonly resemble linear outflows, or jets, that may be low-power versions of the large jets observed in radio galaxies. It is rare, however, that Seyfert galaxies show a compact radio source that can be identified unambiguously as the location of the central engine. To explore the nuclear environment of Seyfert radio jets, we have used the Very Long Baseline Array (VLBA) to image a radio flux-limited sample selected from the CfA Seyfert catalog. We identify new flat-spectrum radio sources that might be self-absorbed components near the central engine. Several Seyfert nuclei show resolved, parsec-scale jets that align well with the larger scale radio structure. Both MERLIN and the VLBA resolve out the central, flat-spectrum radio source of NGC~5929. We consider radio emission and scattering models to explain this peculiar source.
