  We examine the sky distribution of radio galaxies in the NRAO VLA Sky Survey
(NVSS) and the Rapid ASKAP Continuum Survey (RACS). Analyses of these samples
have reported tension between their inferred dipoles and the kinematic dipole
of the Cosmic Microwave Background (CMB). This represents a challenge to the
traditional assumption that the Universe is homogeneous and isotropic on large
scales: the cosmological principle. We find that NVSS and RACS contain local
radio sources which give a non-negligible contribution to the overall dipole
signal. These need to be adequately accounted for since the aim is to probe the
composition of the Universe at large scales. By appropriately considering these
sources, the inferred dipole amplitude in either sample is reduced.
Nonetheless, we find support for a dipole aligning with that of the CMB but
larger in amplitude, especially in the joint analysis. However, the 'clustering
dipole' - the contribution of local sources to the net inferred dipole -
appears to align with the direction of the CMB dipole, and its magnitude
increases as deeper nearby sources are considered up to a comoving distance of
$\approx 130$ Mpc ($h=0.7$). The significance of this observation in the
context of the cosmological principle is unclear and prompts further inquiry.
