We have used a sample of 263 Parkes half-Jansky flat-spectrum radio so
urces to measure the spatial correlation function of radio galaxies an
d radio-loud quasars on scales up to 1000 h(-1) Mpc. We do not detect
any clustering in the sample. If any undetected clustering is describe
d by a power-law spatial correlation function [xi(tau) = (tau/tau(0))(
-1.8)], we can rule out clustering with scales tau(0) greater than or
equal to 50 h(-1) Mpc at the 99.9% confidence level. We have also used
the sample to test for the 'possible' large concentration of quasars
in the direction of the microwave background dipole found by Shaver (1
987). There is no evidence for such a concentration in our data and we
show that the earlier result was probably biased by the use of non-un
iform image classifications.
