  The physical nature of the X-ray/radio correlation of AGN is still an
unsolved question. High angular resolution observations are necessary to
disentangle the associated energy dynamics into nuclear and stellar components.
We present MERLIN/EVN 18cm observations of 13 X-raying AGN. The sample consists
of Seyfert 1, Narrow Line Seyfert 1, and LINER-like galaxies. We find that for
all objects the radio emission is unresolved and that the radio luminosities
and brightness temperatures are too high for star formation to play an
important role. This indicates that the radio emission in these sources is
closely connected to processes that occur in the vicinity of the central
massive black hole, also where the X-ray emission is believed to originate in.
