  We investigate dipole asymmetries in four large radio surveys, each spanning
more than 80\% of the sky. Two of them, the Very Large Array Sky Survey (VLASS)
and the Rapid ASKAP Continuum Survey (RACS), have recently yielded dipoles that
appear incongruent with each other as well as seem inconsistent with previous
radio survey dipoles and the Cosmic Microwave Background (CMB) dipole. Because
these radio surveys have large overlaps in sky coverage, comprising hence large
majority of common radio sources, one would not expect significant differences
between their radio dipoles, irrespective of their underlying source of origin.
We examine here in detail these radio dipoles, to ascertain the source of
incongruency amongst them. We find the VLASS and RACS data to be containing
some declination-dependent systematics, seemingly in the vicinity of the
declination limit of each survey. We show that the effects of such systematics
can be mitigated by restricting the declination limits of the respective survey
during the dipole determination. A weighted mean of the sky coordinates of thus
derived dipoles from the four radio surveys lies within $1.2\sigma$ of the CMB
dipole direction. However, the amplitude appears significantly larger, $3.7\pm
0.6$ times or more than the CMB dipole. This puts in doubt not only the
conventional wisdom that the genesis of all these dipoles, including that of
the CMB dipole, is due to the Solar peculiar motion, it also raises
uncomfortable questions about the Cosmological Principle (CP), the basis of the
standard $\Lambda$CDM cosmological model.
