  We present new XMM-Newton EPIC observations of the nuclei of the nearby radio
galaxies 3C 305, DA 240, and 4C 73.08, and investigate the origin of their
nuclear X-ray emission. The nuclei of the three sources appear to have
different relative contributions of accretion- and jet-related X-ray emission,
as expected based on earlier work. The X-ray spectrum of the FRII narrow-line
radio galaxy (NLRG) 4C 73.08 is modeled with the sum of a heavily absorbed
power law that we interpret to be associated with a luminous accretion disk and
circumnuclear obscuring structure, and an unabsorbed power law that originates
in an unresolved jet. This behavior is consistent with other narrow-line radio
galaxies. The X-ray emission of the low-excitation FRII radio galaxy DA 240 is
best modeled as an unabsorbed power law that we associate with a parsec-scale
jet, similar to other low-excitation sources that we have studied previously.
However, the X-ray nucleus of the narrow-line radio galaxy 3C 305 shows no
evidence for the heavily absorbed X-ray emission that has been found in other
NLRGs. It is possible that the nuclear optical spectrum in 3C 305 is
intrinsically weak-lined, with the strong emission arising from extended
regions that indicate the presence of jet--environment interactions. Our
observations of 3C 305 suggest that this source is more closely related to
other weak-lined radio galaxies. This ambiguity could extend to other sources
currently classified as NLRGs. We also present XMM-Newton and VLA observations
of the hotspot of DA 240, arguing that this is another detection of X-ray
synchrotron emission from a low-luminosity hotspot.
